*All BBB ratings in this article are accurate as of May 2024.
★★★★★
“Very professional crew. Outstanding workmanship. Kept inside and outside of house clean. Would wholeheartedly recommend this crew, these windows, and sliding glass door to anyone!”
—Tim S. via BBB
★☆☆☆☆
“They are great about reaching out prior to installation. Once the windows have been installed, they no longer return your calls. I am missing the sliding glass door screen, one window, and one window was installed with a crack. I have made multiple calls and spoken to several people. They have sent two different contractors out to measure and nothing comes of it. This has been going on for over a year.”
—Heather T. via BBB
Installation Process
Renewal handles installation in-house, so you won’t need to go through an installer network or hire an outside contractor. The brand has its own installation team trained to install its windows. Its installation process is meticulous, including cleaning the jobsite and disposing of your old windows.
Champion Windows
Best for Sunrooms
State availability: 28*
Warranty options: Limited lifetime warranty
Price range: $400–$850

Champion’s other energy efficiency features include its airtight meeting rails, weather-proof composite locking, triple weatherstripping, and insulated pocket sill.

Champion Windows Products We Like
We like that Champion offers numerous eco-friendly products, such as its ENERGY STAR-certified Comfort 365 Window Glass. This glass features a specialized low-emissivity (low-e) coating and an insulating argon gas filling that blocks roughly 94% of harmful ultraviolet (UV) rays. These features mean that you, your guests, and your pets stay cool during summer and warm in winter, while still receiving plenty of natural sunlight. This is a standout benefit given that the homeowners we surveyed cited improved energy efficiency as their second-highest motivation for investing in new windows.
We especially recommend Champion for sunroom or patio projects. The company offers completely customized sunrooms with an in-depth, personalized installation process. This includes projects such as all-season sunrooms, three-season sunrooms, patio enclosures, and screen rooms.

- Bay and bow
- Casement
- Double-hung
- Garden
- Glass block
- Picture

Reputation and Customer Reviews
Champion isn’t currently accredited with BBB, and we noticed its once-high score has recently been changed to “Not Rated.” One reason may be the alert shown on its profile, which notes that many customers have filed complaints that the company isn’t responsive and misses appointment times.
Despite this, Champion still has 3 out of 5 stars from customers out of more than 800 reviews. Positive themes include professional installers and beautiful, high-performing windows. Some customers reported ignored warranty claims and communication gaps.
★★★★★
“Champion installers did a fabulous job! Explained all the aspects of the work and installation.Carefully installed my beautiful windows. So very polite and professional! I appreciate the attention to detail.”
—Linda K. via BBB
★☆☆☆☆
“Terrible customer service. Delivery of items not timely or correct. Phone calls to customer service & local office not returned. Job not completed until 10 months after contract signed.”
—Karol W. via BBB
Installation Process
Champion is another company that has its own in-house installation team. Its site says it finishes most installations in a day and that its limited lifetime warranty covers every aspect of the installation. The company even includes a video on its full installation process.

We like that Castle features a 24/7 customer support line, which we tested by calling at 10:30 p.m. ET. We also like that Castle offers a transferable lifetime warranty, covering all parts, glass, and components of your windows, including screens.
Castle’s site doesn’t include many details about its energy features, but it does say it constructs its windows using double-pane, double-strength glass and dual security locks. We did find that it applies a low-e glass coating to its windows and adds nontoxic argon gas between panes for added insulation.

★★★★★
“This was my best experience with a home renovation company. Castle is nothing but professional from top to bottom. Start to finish, the process was surprisingly fast. When calling the company, you reach a live person who listens and gets you to the correct people to keep the process moving forward. Installers went above and beyond to correct issues caused from previous installation. I would recommend to anyone. The product and service were worth the cost.”
—Craig U. via BBB
★☆☆☆☆
“Our windows are actively leaking and causing damage to our trim and drywall. They are claiming it’s not covered by the warranty, which the warranty states it is. We asked for an appt for repair to the windows, which we would pay for. The appt day and time comes and they don’t show up.”
—Lauren E. via BBB
Installation Process
Castle’s website doesn’t mention installation services, but its customer reviews and warranty details tell us it offers in-house installation services.
Marvin Windows
Best for Coastal Homes
State availability: 50
Warranty options: Limited warranties
Price range: $250–$900
Energy-efficient products available: Yes
Based out of Minnesota, Marvin Windows has more than 100 years of experience in the window replacement industry. This leading manufacturer has eight factories across the United States to produce various window types and materials. Marvin produces windows with wood, fiberglass, and extruded aluminum materials, and it offers three signature collections.
Though Marvin’s site thoroughly details what to look for when assessing energy efficiency, it doesn’t describe how its windows perform. Marvin does mention that its proprietary fiberglass frame material is three times stronger than vinyl/wood composites and will outlast vinyl framing by 38%. The brand claims its fiberglass materials provide superior thermal performance.
Pros and Cons
Pros
- Has hurricane-rated windows for coastal homes
- Sells skylights
- Has many custom design options, including hardware
Cons
- Features limited warranty options compared with other providers
- Doesn’t have in-house installation services
- Doesn’t make vinyl window options
Marvin Windows Products We Like
We recommend Marvin’s Signature Ultimate windows and doors. These are available in a range of wood species and various stains and paint options. Marvin sands, conditions, stains and oven-cures each piece of wood for an added layer of luxury. This process provides a rich finish. We also suggest Marvin’s Signature Coastal windows if you own a coastal home. The company designs these windows to operate in extreme storms and hurricanes.
Types of Windows Available
Marvin makes the following windows:
- Awning
- Bay and bow
- Casement
- Corner
- Double-hung
- Picture
- Single-hung
- Skylight
- Sliding
- Specialty
Reputation and Customer Reviews
Marvin has an A+ rating on its BBB profile, but its 1.3 out of 5 stars from customers is much lower than the customer ratings of competitors. A common complaint is finding faulty window parts that the company doesn’t replace or repair promptly.
Our rating of the company using our methodology scores Marvin 4.6 out of 5 stars in key categories, so we’re still including it on our list as an option. We’re also mentioning it here because it’s one of the few brands that makes energy-efficient skylights and has a range of coastal-friendly window options.
★★☆☆
“While the windows are pretty, the jams were bowed on nearly every window. What is worse is that one of our windows arrived damaged. Our contractor has been waiting for four months to get a replacement window. We spent over $35,000 on Marvin windows and have been on hold for four months waiting for them to respond.”
—Christine H. via BBB
★☆☆☆☆
“We purchased seven windows and a slider window in 2022. Nothing but problems with the windows. The installer has done everything possible to correct our issues. While condensation is normal and expected in the winter months due to high humidity, our windows sweat to the point the frames, sills, sash around the window, and window pull are dripping wet on every window.”
—Dan A. via BBB
Installation Process
Marvin is another manufacturer that doesn’t provide installation. You can use its Find a Dealer page to locate an office near you.
Harvey Windows
Best for Wooden Windows
State availability: 22*
Warranty options: 10-year and lifetime warranties
Price range: $500–$1,350
Energy-efficient products available: Yes
A trusted name in the Northeastern United States, Harvey Windows and Doors offers two different window lines. We consider its solid Ponderosa Pine Majesty Wood collection one of the best wooden windows on the market. These windows have been specially treated to resist rot, degradation, splitting, warping, and mildew. They also have extruded aluminum exterior cladding to protect the sashes from outdoor conditions. Additionally, Harvey bevels these windows to match the aesthetics of other wood windows.
Harvey lists several energy efficiency features that enhance its windows’ performance, starting with the thick walls and multiple air chambers it builds into its frames and sashes to enhance thermal insulation. The company also applies a low-e coating to control heat transfer, as well as advanced weatherstripping, argon gas filling between panes, and a u-channel spacer system that better insulates around the edges of the glass.
*Available in Alabama, Connecticut, Delaware, Georgia, Illinois, Indiana, Kentucky, Maine, Maryland, Minnesota, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, and West Virginia.
Pros and Cons

- Protects quality vinyl windows with lifetime warranty
- Offers UV Tough Coat paint
Cons
- Has limited state availability
- Offers only 10-year warranties on its Majesty Wood windows
- Doesn’t offer in-house installation services
Harvey Windows Products We Like
The Majesty Wood collection is backed by only a 10-year warranty, but Harvey’s Classic Vinyl collection includes a lifetime warranty. Its Classic Vinyl collection comes with five BetterGrain interior finishes, which mimic the look of natural wood windows. You can pair these premium vinyl windows with the company’s UV Tough black or bronze stock colors. This coat is seven times stronger than industry-standard water-based paints, ensuring your windows will look great longer.

Harvey sells these window types:
- Awning

- Picture
- Rolling

Reputation and Customer Reviews
Harvey has an A+ rating on its BBB profile and an impressive 4.8 out of 5 stars, the highest customer rating we’ve seen in the window industry. Reviewers point out quick, easy communication and problem resolution, as well as good window quality and an easy warranty claim process. The few negative reviews mention niche issues, such as changes in distribution, which the average customer isn’t likely to have a problem with.
★★★★★
“Great experience with Harvey. When I moved there were several broken window sashes. Called Harvey and someone answered the phone right away and it was no problem to replace the damaged sashes even though I was not the original purchaser. Replacements were mailed directly to my home and I only had to pay for shipping. There was an issue with one of them, but customer service was great and sent out a replacement. They were easy to install and look great.”
—Nancy O. via BBB
★★★★★
“I called to find out if my 16 year old window was guaranteed against seal breakage and your rep was more than patient and helpful. She located my original order and confirmed that I was still under guarantee to replace the glass and how to go about having it installed. I couldn’t have been more pleased with how I was treated.”
—Donna S. via BBB
Installation Process
One downside to Harvey is that it doesn’t handle installation in-house. Rather, you must go through one of its distributors or hire a licensed outside contractor.
Milgard Windows
Best Specialty Windows
State availability: 12*
Warranty options: Full and limited lifetime warranties
Price range: $200–$600
Energy-efficient products available: Yes
Unlike other window companies that rely on third-party providers to produce their glass and hardware components, Milgard manufactures all parts of its windows entirely in-house. We tested Milgard’s chat feature on its website to ask what the benefits of in-house manufacturing are. A representative explained that keeping everything under one company allows for better communication due to fewer parties involved, as well as faster production and delivery, a higher likelihood of product quality, and more comprehensive customer support. It also means a more robust warranty.
Milgard is one of the few brands that offers three frame materials: vinyl, fiberglass, and aluminum. All of its windows can be customized with a range of colors, grid layouts, and hardware options. You can also choose from different glass packages, such as tinted or obscured. All glass is made with Milgard’s SunCoatMAX low-e coating and dual-glazed technology, which it says gives double-pane windows triple-pane performance. Like many energy-efficient window brands, Milgard inserts insulative gas between window panes for added performance.
*Available in Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Texas, Utah, Washington, and Wyoming.
Pros and Cons
Pros
- Provides a full lifetime warranty option for some series
- Sells three frame material options
- Offers SmartTouch Hardware for easy locking and unlocking
Cons
- Doesn’t offer in-house installation services
- Has limited state availability
- Has a limited window selection compared to many brands
Milgard Windows Products We Like
Though Milgard doesn’t offer wooden windows, it provides various other options to fit your home’s style. Its Trinsic Series | V300 has a modern look with thin frames and a minimalist design. TheUltra Series | C650 uses wood-clad fiberglass, so it withstands heavy weathering but maintains a traditional wooden window aesthetic.
Milgard offers an excellent selection of specialty windows, including skylights. Other specialty window options include high-quality radius, bay, bow, and garden windows.
Types of Windows Available
Milgard makes the following window types:
- Awning
- Casement
- Double-hung
- Picture
- Single-hung
- Sliding
- Specialty
Reputation and Customer Reviews
Milgard has an F rating on its BBB profile, but we’ve included it on our list because it has one of the highest customer ratings of any brand, so this rating may be inaccurate. Milgard has 4.6 out of 5 stars from more than 700 customers, which we feel is a more accurate representation of the company.
Customers cite high-quality windows, efficient and respectful employees, and a positive warranty experience. A small percentage of customers report a lack of responsiveness and claim denial.
★★★★★
“We’ve had our Milgard windows for almost 20 years. They are outstanding quality, and when we’ve had a few minor issues they are handled quickly and professionally.”
—Darrell H. via BBB
★★★★★
“My service guy did a really great job. The windows look wonderful. He was careful of my furnishings and kept his work area clean. He was courteous and quick. I am very pleased with the results.”
—Charlene W. via BBB
Installation Process
Milgard doesn’t have an in-house installation team. You can check its Dealer page to find a location near you that you can arrange installation through, or you can hire a third-party contractor. Milgard provides detailed installation guidance on its site.
Pella Windows
Best Eco-Friendly Windows
State availability: 50
Warranty options: Limited warranties
Price range: $450–$2,000
Energy-efficient products available: Yes
Pella is one of the largest window manufacturers in the United States and can be found at home improvement retailers such as The Home Depot and Lowe’s. We like that it prioritizes green technology and energy-efficient windows, helping you to keep your home comfortable during cold winters and hot summers while benefiting the environment. Pella uses sustainable sources and works with wood vendors who practice responsible harvest and replenishment.
Additionally, most Pella windows and doors meet ENERGY STAR performance guidelines and include a low-e insulating coat. The Environmental Protection Agency (EPA) even recognized Pella for its efforts in pollution prevention with an ENERGY STAR Award in 2009. Pella claims its 250 series’ triple-pane windows are 62% more energy efficient than single-pane windows on average. Upgrading to Pella’s energy efficiency package allows you to bundle triple-pane glass design with upgraded AdvancedComfort low-e glass and built-in blinds or shades designed for maximum efficiency.

Pella Windows Products We Like
Pella offers a large selection of window lines. Its Architect and Lifestyle series include high-quality, detailed wooden windows. These windows feature a traditional, timeless design with finely detailed sash and grille profiles to add architectural interest to your home. Pella also offers a minimalist, durable line of fiberglass windows in its Impervia series.
Types of Windows Available
Pella makes the following window designs:
- Awning
- Bay and bow
- Casement
- Custom
- Double-hung
- Picture
- Sliding
- Single-hung
- Specialty
Reputation and Customer Reviews
Pella’s A+ BBB rating affirms the brand’s quality, but its customer rating of 1.3 out of 5 stars signifies some issues in how the company does business. However, we did see that its most recent reviews indicate that quality and service are on an upswing, so it’s possible former issues have been resolved. Customers report loving their windows long-term, while others said window features weren’t as promised and support professionals were unhelpful in resolving issues.
★★★★★
“Pella is back on top with their quality and service! Very thoughtful company and quality with their products and follow-up with their staff.”
—Janet S. via BBB
★☆☆☆☆
“I will never put Pella windows in my house again! I built a home 20 years ago and put all Pella windows in. I have one window that the roll-down screen will not lock in place. I called for a service and they said it would be $225 just to come out, and they cannot guarantee they will have a part to fix it and I would still have to pay the $225 because all these windows have been discontinued.”
—Tom I. via BBB
Installation Process
Pella doesn’t have in-house installers. You can enter your location on its site to find a Pella-certified contractor or purchase Pella windows at a local home improvement retailer and ask about professional installation there. Another option is the company’s Power by Pella partnership with Power Home Remodeling, which is also featured on our list. Power Home expertly installs certain Pella window collections, meaning you’ll get a Pella manufacturer’s warranty and Power Home workmanship warranty.
What to Consider When Buying New Windows
The right windows for your home are the ones that suit your style while being within your budget and offering a substantial return on investment through their performance. Performance should be your top priority. If you must compromise on anything, make it superficial features, such as hardware or customization options. Invest first in energy efficiency.
Generally, here are a few big factors to consider when buying new windows:
- Value: You likely don’t need to invest in every feature a company offers. Focus on the performance that most provides value for you. For example, if you live in a mild or moderate climate, there’s no need to splurge on triple-coated windows.
- Energy efficiency: Improving energy efficiency is among the best and most common reasons to upgrade windows. If you live in an area with extreme temperatures or weather, the material and design of your windows need to be suitable for that climate. Look for windows that are ENERGY STAR-certified. These will have a label that details which climate the window is best suited for.
- Window type: Windows come in all shapes and sizes. Choose styles that complement your home’s architecture, age, and scale. For example, bay, bow, and picture windows are ideal for large rooms with great views.
Average Cost by Window Type
The cost for new window installation or replacement depends on the brand you choose, but that’s not the only factor. Material and style selection also play an important role in the final price. Expect to pay significantly more for a large bay window than a standard double-hung window. You might also pay more for materials such as wood window frames—however, in our research, this cost difference is minimal. We found that double-hung wood windows, on average, cost $300 more than aluminum windows of the same style.
Below, we’ve broken down the costs you can expect for several popular window materials.
*RSMeans data from Gordian
Energy Efficiency
Nearly 92% of the homeowners we surveyed said ENERGY STAR certification was important to them, and over 78% said they noticed a reduction in electricity bill costs after upgrading their windows. If you want windows that don’t just look nicer in your home but also help you save money, look for an ENERGY STAR-certification, National Fenestration Rating Council (NFRC) certification, and other markers of energy efficiency. Common features include triple-pane glass, low-e coatings, and additional insulation.
The Department of Energy recommends looking for two main ratings when buying windows: U-factor and the Solar Heat Gain Coefficient (SGHC). The U-factor measures how well the window insulates. The lower the U-factor, the better the window insulates. The SGHC measures how much of the sun’s heat comes through the window. The lower it is, the less solar heat the window allows.
For northern climates, ENERGY STAR recommends windows with the following ratings:
| U-Factor | SHGC |
|---|---|
| ≤ 0.22 | ≥ 0.17 |
| = 0.23 | ≥ 0.35 |
| = 0.24 | ≥ 0.35 |
| = 0.25 | ≥ 0.40 |
| = 0.26 | ≥ 0.40 |
For other climates, ENERGY STAR recommends:
| Climate Zone | U-Factor | SHGC |
|---|---|---|
| North-Central | ≤ 0.25 | ≤ 0.40 |
| South-Central | ≤ 0.28 | ≤ 0.23 |
| Southern | ≤ 0.32 | ≤ 0.23 |
“[Energy Star] carries the reputation of being the best on the market, and will put a few dollars back in your pocket with your heating and cooling bills,”
– Colin Sullivan, Director of Production for Renewal By Andersen’s Carolinas Division
Types of Windows
While double-hung windows are a popular type of window, casement windows are one of the best choices due to their energy-efficient characteristics and low maintenance. Below are the most common window styles you’ll encounter during your search.
- Awning Windows: These windows swing open to the outside of your home as if you are pushing a latch open. This design makes them easier to clean and ideal for climates with a lot of rain, as the design pushes rainwater away from your home rather than towards it.
- Bay Windows: Bay windows extend from an exterior wall and create a small shelf in the home. They use multiple flat windows set into an angled frame that protrudes from the home. This design creates a beautiful accent to your home’s walls and provides curb appeal.
- Bow Windows: Bow windows use custom curved windows to create a circular area along the outside of your home. They provide extended views of lawns or gardens and are ideal for breakfast nooks and dining areas.
- Casement Windows: Casement windows swing out to the side or up to open. One of the most popular windows you see in homes, they tend to be constructed of solid glass and lend to a sleek, minimalist design.
- Custom Windows: Most window replacement companies offer custom windows. So whether you want a window designed to look like a sailboat or one that captures the spirit of nearby mountains and forests, if you dream it up, a window replacement company can most likely help make it a reality.
- Double-Hung Windows: These are among the most common types of windows you find in homes. Though similar to a single-hung window, a double-hung window has a lower sash and upper sash that moves up and down. Often, these windows feature a built-in slash tilt for easier cleaning.
- Garden Windows: These windows are one of the best ways to instantly add character and charm to your home. Garden windows are similar to bay windows as they protrude from your home. However, they feature small shelves to store plants and herbs to receive sunlight and be visible from outside.
- Hopper Windows: Typically found in basements and bathrooms, hopper windows are ideal for any room with limited wall space. Commonly used for ventilation, they open from the top and usually crank open to tip down.
- Picture Windows: Picture windows don’t have visible frames or other breaks, making them ideal for enjoying an obstructed view and making your interior feel larger. These fixed windows can’t be opened, but they are often paired with other windows for design and functionality.
- Skylight Windows: Skylight windows act like windows for your roof and allow you to add more natural light to homes with limited wall space.
- Single-Hung Windows: Single-hung windows open vertically with their bottom window panel. The lower sash moves up and down, but the upper sash remains stationary.
- Sliding Windows: Ideal for elongated walls, sliding windows feature two sections usually made from single windows. One of the sections slides horizontally over the other to open or close.
- Transom Windows: Transom windows are often used as decorative accent windows. They help break up space or add a design focal point. You often find them around doors or above other windows, and they tend to be semicircles, rectangles, or squares.
Window Warranties
Most window manufacturers offer limited lifetime warranties and/or labor warranties. Limited lifetime warranties cover the cost of the window parts but do not always cover the labor.
The term lifetime often refers to the estimated time the window will maintain its manufactured quality. For example, lower-quality windows may have an estimated life span of fewer than five years, while higher-quality windows may be expected to last for more than 15 years. The length of the warranty will match those estimations. However, some manufacturers mean the actual lifetime of the window. These warranties also tend to be transferable to new homeowners.
Lifetime limited window warranties typically cover the following items:
- Window materials
- Cosmetic defects
- Broken/malfunctioning hardware
- Energy-efficient glass
- Obstructed vision/seal issues
- Installation/contractor errors
- Custom aspects of your design
- Accidental damage to the glass
A labor warranty covers installation errors, not manufacturing defects. Labor warranties may require you to pay a service call fee.
Window labor warranties typically cover the following:
- All installation and labor
- Glass systems and frames
- Pieces, parts, and materials
- Locks and hardware
We recommend hiring a window installation contractor that the manufacturer approves. This makes it easier to receive coverage if an issue occurs. Otherwise, the manufacturer may try to blame the installer or vice versa.
What to Look for in Homeowner Reviews
Reading other homeowners’ reviews will help you gain an accurate insight into what it’s like dealing with a particular company. We read more than 100 reviews for each company we researched to see what homeowners had to say about product performance, customer service, timeliness, responsiveness, professionalism, pricing, and other factors that affect your experience.
Below are the most common factors customers report making or breaking their window-buying experience. We recommend paying close attention when these factors come up in customer reviews.
- Response time and scheduling: Take note of how long homeowners said they waited for windows to be installed. A company that takes a while to schedule an installation date may not be a dealbreaker if your remodel doesn’t require a fast turnaround. However, if you need a shattered window replaced quickly, you may want to find a company homeowners praise for speedy response times.
- Warranties: Customer reviews are also an excellent opportunity to tell if a company honors its warranties or puts misleading language in them. Pay attention to reviews that mention trying to use a warranty for glass repair or a malfunctioning lock to gauge whether or not the window brand stays true to its word.
- Workmanship: Note how homeowners describe the quality of both the installation and the windows themselves. Avoid brands whose workmanship might involve cheaper parts or a sloppy design.
How to Compare Window Quotes and Pricing
Window companies allow you to get a quote online and by phone. Most brands’ websites include a quote form you can quickly fill out. Some ask only for your contact information, while others may ask a few other questions about your home or the windows you’re interested in. You’ll have to wait for a representative to reach out to you to get your quote, which may take a couple days. Since the representative will ask you further questions over the phone about your home and what you’re looking for, you may want to just call and skip the wait.
We recommend getting a quote from at least three companies to compare pricing. When comparing costs, don’t just look at the number. Rather, compare the value for the price. Look at which customization options, energy features, labor, warranty coverage, financing options, etc. at that cost.
Financing and Payment Options
The most cost-effective way to pay for new windows is to pay in full upfront. If this expense is too high, window companies offer financing options. Some brands offer financing in-house, while some work with third-party lenders. The most common types of window financing options include:
- FHA rehab loan: The Federal Housing Administration provides mortgage loans to help homeowners finance necessary home improvements. The process is typically easier than traditional loans, but you do have to make a down payment and may face a high interest rate.
- Home equity loan: A home equity loan allows you to borrow against the equity of your house. You’ll get a lower interest rate than an FHA loan, but your home will be considered collateral.
- In-house loan: Plenty of brands offer in-house financing with attractive incentives, such as 0% down, 0% interest, and no payments for 12 months. Champion is one brand with appealing loan terms.
- Personal loan: This loan type commonly has a fixed interest rate. If you have a high credit score, you can arrange a personal loan with your bank.
Also look for other incentives that help make paying for your windows more manageable, such as discounts for buying a certain number of windows or seasonal deals.
Choosing a Local Window Installer
Choosing the right windows and manufacturer isn’t all there is to consider. If your manufacturer doesn’t provide in-house installation, you’ll need to go through its installer network or browse local contractors to put the windows in. This shouldn’t be an afterthought. The quality of the window installation is just as important as the quality of the windows themselves. Improper installation can lead to poor energy efficiency, voided warranty coverage, and window or wall damage.
Steps to Take When Choosing an Installer
Take the following steps to find a reputable local window installer:
- Check for certification: Many window manufacturers recommend or sometimes require hiring an installer trained and certified for their products. We suggest visiting a local showroom of the brand you’re interested in to connect with local certified installers. Double-check for certification from the American Window and Door Institute, and check that the contractor is properly licensed and insured for window installation in your state via your state’s contractor licensing board.
- Read customer reviews: Google Reviews and the BBB are two great sites to find reviews. We suggest paying special attention to the criteria listed above when reading homeowner reviews, such as scheduling, warranty options, customer support, energy efficiency, and workmanship. You can also ask a company for references. Ask these individuals about any delays in their project, window performance, energy bill changes, the crew’s professionalism, their labor warranty, and whether the crew cleaned up the project area and disposed of the old windows.
- Pay attention to the quote process: A reputable installer should measure each replacement window, explain their installation process, and estimate how long the job will take. You want an installer who will replace each window one at a time, rather than taking out all the old windows at once and installing new ones. If an installer seems too quick to start the job or tries to avoid some of your concerns and questions, you may want to check out another local installer. Don’t work with an installer who wants to start working before giving you a legally binding, itemized cost rundown.

What Type of Window Is the Most Durable?
The most durable type of window is fiberglass. This refers to window material rather than style. Window frames are typically made from aluminum, vinyl, composite, fiberglass, or wood. While all are considered plenty durable, fiberglass is superiorly weather-resistant and low-maintenance. It won’t rust, warp, corrode, or rot. It provides excellent insulation and energy efficiency and is known for its long life span. Many window brands include longer and more comprehensive warranties for their fiberglass window options due to how reliable and high-quality it is. You’ll typically pay more for fiberglass windows than any other material type, but you’ll also see a better return on investment on average for such a durable material.
