We've ranked the top 10 window replacement companies that operate within 50 miles of Knoxville. We base our ranking off average customer ratings weighted against the number of reviews. For more information, check out our full methodology.
Updated windows with the newest features can keep your home comfortable and energy efficient by helping you save on monthly energy bills and preventing your HVAC system from overworking. The U.S. Department of Energy found that both heat and cold can transfer from inadequate windows, which accounts for 25% to 30% of energy expenses for homeowners. The best window replacement companies in Knoxville can help you find aesthetically pleasing, energy-conserving alternatives.
Investing in high-grade, energy-efficient windows begins with knowing what to research. First, we suggest opting for replacement windows with an Energy Star label. This certification confirms that the window complies with the performance criteria defined by the National Fenestration Rating Council. The label also displays the climate where the window will function best: northern, north-central, south-central or southern.

Find the best window replacement company for you in Knoxville
The best window replacement companies in Knoxville provide extensive product options, comprehensive warranty policies, competitive estimates and a track record of quality work.
Since Knoxville is located in a north-central climate zone, you should look for a U-Factor of less than 0.25. This ensures the window is insulated enough for colder months. The lower the number, the better the window retains heat. You should also look for a Solar Heat Gain Coefficient (SHGC) of less than 0.4. The lower the SHGC, the better the window resists unwanted heat gain and the less you’ll spend on cooling in summer.

What are signs that I need my windows replaced?
Your windows will often indicate when replacement is necessary. Usual clues that it's time for an upgrade include the following:
- Escalating energy bills
- Condensation between glass panes (moisture on the exterior or interior of panes is normal)
- Poor operation, such as not opening or closing easily
- Air leakage around windows
- Poor curb appeal due to age or weathering
- Damage, such as cracked glass or broken framing
- Problematic noise pollution from outside
You can just update a single window if it's faulty or otherwise needs upgrading. However, if you have windows throughout the house with poor efficiency or outdated looks, swapping all of them out will give you the most successful upgrade.
Deciding not to replace your inefficient or broken windows can cost you down the road. Problems like air infiltration can make your utility bills spike dramatically and put extra strain on your HVAC system. Excess moisture can result in window decay and potentially mold in your house. Faulty windows might also pose a security risk if the damage could allow intruders to easily enter your home.
How much does it cost to replace windows in Knoxville?
Window replacement costs depend on various factors, but expect to spend about $220 to $330 per window for materials in Knoxville, according to RSMeans. Factors such as the size and complexity of your project will affect labor costs. October 2023 survey of homeowners put the national average cost for a window installation project with up to five windows at $9,014 for aluminum-frame windows and $9,403 for wood-frame windows.
Window replacement cost factors
Several components determine what you’ll ultimately spend to replace your windows, including their style, materials, energy-efficiency features, glass type, the age of the house and the placement of the windows around the home. Costs are higher for more detailed styles, such as bay windows or bow windows, and you'll also pay more for higher-quality materials like wood, composite and fiberglass.
Window replacement cost by replacement type
Window replacements come in two forms: pocket and full-frame. If your issue is confined to a cracked pane, you'll simply need glass replacement done by an installer, rather than a completely new window unit installed. But for defective window framing, poor insulation that causes drafts or moisture seepage, you'll need to consider a full-frame replacement, despite the bigger price tag attached.

How can I save money on Knoxville window replacement?
Window replacements offer ongoing value, but paying the most reasonable price now is important, too. We recommend saving money in the following ways:
- Pay in cash or by check: Plenty of companies add fees if you pay with a credit card. An extra 3% on top of spending hundreds or thousands of dollars can steeply inflate your final bill.
- Consider a different window style: If pricier windows catch your eye, write down their most appealing visual features and then find reasonably priced options with the same traits. If you want ample natural light and a great view, choosing a picture window over a bay window can save you a ton of money and still provide both attributes.
- Purchase in the off-season: To replace units, the windows will need to be open over the course of a few days, so many people do updates during the warmer months. If you’re okay with a winter installation, you may be able to get a deal from window companies seeking clients in those months.
- Compare estimates: Ask for the estimated project cost from multiple sellers to contrast pricing. Evaluate the quality each window type is to ensure you're optimizing your investment.
- Choose standard colors and sizes: Customizations can raise what you pay without helping the windows function any better.
- Buy in bulk: Bundling all window replacements together costs less overall compared to buying windows individually over time. Window retailers often cut prices if you purchase a lot of units together in one order. Companies also commonly increase the price of windows yearly, so purchasing everything together helps avoid those gradual hikes.
Our methodology for selecting window replacement companies
The Homefront Local team employs a proprietary scoring algorithm that evaluates companies based on key factors you value, such as average customer review ratings and trustworthiness indicators. Our method for determining trust involves a comparative analysis of the number of reviews a company receives compared to its local competitors. This leads to companies that have earned more trust from your local community being awarded a higher score.
We review national window companies against our full methodology. We score window companies based on window options, energy-efficiency features, warranties, reputation and reviews, customer service and communication, and installation and other services.
