How Installing Energy-Efficient Windows in Coventry Saves You Money

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

  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Reduce your carbon footprint: In Coventry, you can cut 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

Each window installer provides various services and has varying costs depending on several factors.

How Much Do New Windows Cost?

Generally, Coventry homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. These estimates are based on specific characteristics of your installation, such as type, size, number of windows, material, the location of your home and more.

It’s important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Coventry homeowners $461+ a year when replacing single-pane windows.

Another factor that influences the overall cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the complete window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which kind of installation you need, you can talk to your provider and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Coventry

In our search to make your home improvements easier and more eco-friendly in Coventry, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:

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 choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency 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

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a variety 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Coventry, CT Window Replacement FAQs

What is the typical cost to install new windows in a home?

The typical cost of installing one window ranges from $450 to $650. There are many factors that influence the price, including styles and sizes of windows, the materials used in designing the windows, your property’s location, the number of windows, how energy-efficient the windows are and local labor costs.

What kind of window is the most energy-efficient?

A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

Do I really have to use a window installation company?

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

What time of year is the best time to replace my windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
