How Installing Energy-Efficient Windows in Knoxville Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could help you:

• Better temperature control in your home: Living in a hot place like Knoxville can often mean relying on your air conditioner to keep your house cool. Energy-efficient windows can cut back on how hard your AC needs to work to cool your home.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Better temperature control in your home: Residing in a very cold place like Knoxville can often mean depending on your heater to keep your home cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.

Estimated Cost of Window Replacement in Knoxville

Let's take a look at the cost of window installation and the types of services offered by installers.

How Much Do New Windows Cost?

According to our market research, the average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. Costs will differ significantly based on the number of windows you need, your location, the current condition of your home and the quality of your products. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

It's also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Knoxville home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of damage. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails installing a new window without replacing the frame. So, instead of removing the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can recommend the best type for your project. In Knoxville, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Knoxville

In our hunt to make your home improvements easier and more eco-friendly in Knoxville, the EcoWatch team assessed dozens of companies before settling on these. We have assessed the top window installation companies in Knoxville mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Knoxville, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Knoxville.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, cost, warranty, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Knoxville's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Knoxville window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
