Glastonbury Window Cost Calculator

How Installing Energy-Efficient Windows in Glastonbury Saves You Money

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

  • Better temperature control in your home: Living in a very cold city like Glastonbury often means depending on your heater to keep your house cool. Energy-efficient windows can lower how much heat is lost through your windows when heating your home.
  • Save money on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Glastonbury

Windows come in different shapes, purposes and styles, so costs and services will differ tremendously based on several factors. Below, we describe the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

According to our research, the typical cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. This is because the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

It's important to keep 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 certified energy-efficient windows can save Glastonbury homeowners $446+ a year when replacing single-pane windows.

Getting free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the complete window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has noticeable damage or rot. Full-frame installations are more involved and will raise the overall cost. Pocket installations are simpler and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

Your window installation company will be able to help you decide what's best for your needs. In Glastonbury, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Glastonbury

EcoWatch reviews are different from most reviews because we're examining these companies through a sustainability lens. We've assessed the top window installation companies in Glastonbury primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve Glastonbury so you can find a quality window installation company near you.

Work Quality

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

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have nice things to say about their experience with a certain company, it won't be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important. 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 installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
