Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Whether you're updating for aesthetics or have damaged windows, windows play a key role in conserving your home's energy. The Department of Energy estimates that heat or cool air lost through outdated or drafty windows could account for nearly 30% of residential energy climate costs. In Coventry, where the energy bills are an average of $37 per month, that's almost $$132 per year wasted.

That's bad news for both your wallet and the environment, but one of the top window installation companies can help you with that.

Efficient windows are of particular importance in Coventry, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $461 a year.

How Installing Energy-Efficient Windows in Coventry Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:

  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • 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.
  • Reduce your carbon footprint: In Coventry, you can lower your indirect greenhouse gas emissions by about 147 pounds per year when you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Coventry

Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and services that you can 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 around $600. However, window replacement costs can range from $200 to $1,200 a window. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Coventry homeowners $461+ a year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window installation is to figure out whether you need a full-frame or pocket installation.

A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're not sure which kind of window installation service you should get, your installer can help you out. Typically, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Coventry

The EcoWatch Reviews team is different from most reviewers since we look at these companies through a sustainability lens. We have reviewed the top window replacement companies in Coventry mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

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

Work Quality

When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Because of Coventry's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Coventry window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Coventry, CT Window Replacement FAQs

How much does window installation cost?

The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on several factors. The price is typically influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What type of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

Do I really need to use a window installation company?

You should hire a window installation company whenever you need to replace your windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best handled by the professionals.

When is it time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.

Should I replace all my windows at the same time?

If you're upgrading your windows to save on your energy bills, replacing all of the windows together is the only way to gain that benefit. On the other hand, if you have only a few windows that are broken or leaky, you can replace just those.
