How Installing Energy-Efficient Windows in Newtown Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, such as:

• Save on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Protect your investment: When your home is on the older side, your windows could also be outdated or drafty.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.

Estimated Cost of Window Replacement in Newtown

Each window installation company provides varying services and has different price points depending on a few factors.

How Much Do New Windows Cost?

Generally, homeowners in Newtown can expect that most window installations will range from $250 to $1,200, with the average cost at around $600. But costs will differ considerably based on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.

It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Newtown homeowners $312+ a year when replacing single-pane windows.

Requesting free quotes from multiple providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

In general, there are two types of window installation services companies offer: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to advise you on the best type for your project. In Newtown, the choice will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Newtown

EcoWatch reviews differ from other reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for Newtown, we only included companies that provide services to the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Newtown.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a range 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 that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
