How Installing Energy-Efficient Windows in Knoxville Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:

• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Knoxville, that’s about 477 pounds per year on average.
• Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient windows can help decrease that number, which helps you save some money on your bills.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Knoxville

Windows come in different purposes, styles and shapes, so costs and services will differ considerably depending on your project. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These figures are based on the specifics of your installation, such as type, material, number of windows, size, the location of your home and more.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $305 a year on your energy bills in Knoxville.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also provide 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?

When considering window installations, there are typically two types that your provider will offer: full-frame and pocket installations.

A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation involves replacing a window without taking out the whole frame, which is generally cheaper than a full-frame installation.

If you’re still debating which kind of installation to get, you can talk to your installer and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Knoxville

EcoWatch reviews differ from most reviews, as we evaluate these companies through a sustainability lens. We have decided to assess the top window installation companies in Knoxville mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window companies won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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