Willimantic Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Willimantic, CT using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Willimantic Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, such as:

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
  • Better temperature control in your home: Energy-efficient windows can lower how hard your heating system needs to work to heat your home.
  • Save on energy bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.

Estimated Cost of Window Replacement in Willimantic

Windows come in different styles, shapes and purposes, so costs and services will vary tremendously based on several factors. Below, we detail the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. This is because window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $457 a year on your energy bills in Willimantic.

Requesting free quotes from several installers 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 kinds of window replacement services you can get: full-frame and pocket installations.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation entails replacing a window within the frame that's already there. So, instead of tearing out the whole unit 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 help you choose what's best for your needs. In Willimantic, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Willimantic

The EcoWatch Reviews team differs from most reviewers because we examine these companies through a sustainability lens. We have evaluated the best window installation companies in Willimantic primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window 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

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, quality of installation, quality of parts, warranty, cost and more.

Cost

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

Warranty

As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Willimantic's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Willimantic window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
