How Installing Energy-Efficient Windows in Knox Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to think about making the switch:

• Save on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Knox, that's about 642 pounds per year on average.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Knox

When looking into window installation, each company provides varying services and costs. Let's look at some typical costs and services.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range from $200 to $1,200. These figures vary depending on specific characteristics of your installation, like number of windows, type, the location of your home, material, size and more.

It's also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Knox home translates to 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. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, 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?

There are typically two types of window installation services: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Knox, the decision will mostly depend on the efficiency of your home and the age of your existing frames.

In our search to make your home improvements easier and more eco-friendly in Knox, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Knox and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Knox, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Knox.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of installation, cost, quality of parts and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
