How Installing Energy-Efficient Windows in Green Knoll Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:

  • Reduce 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.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Green Knoll

When looking into window installation, each company offers different services and prices. Let's go over some typical costs and services.

How Much Do New Windows Cost?

Although the average to replace a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost you varies depending on several factors, like number of windows, the location of your home, type, material, size and more.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $273 a year on your energy bills in Green Knoll.

We recommend requesting free quotes from multiple window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first step when considering a window replacement is to figure out whether you want a full-frame or pocket installation.

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you're still debating which type of installation you need, you can ask your provider and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Green Knoll

EcoWatch reviews differ from most reviews since we evaluate these companies through a sustainability lens. We have evaluated the top window installers in Green Knoll mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Green Knoll area so you can find the best window installation company near you.

Work Quality

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

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, professionalism, quality of parts, warranty, quality of installation and more.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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