How Installing Energy-Efficient Windows in Coventry Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:

  • 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.
  • Save money on power bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
  • Better temperature control in your home: Residing in a very cold place like Coventry can often mean needing your heater to keep your house cool. Energy-efficient windows can lower how hard your heating system needs to work to heat your home.

Estimated Cost of Window Replacement in Coventry

Let's take a look at the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

According to our research, the typical cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. These amounts are based on specific characteristics of your installation, including material, size, the location of your home, type, number of windows and more.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $461 a year on your energy bills in Coventry.

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

Generally, there are two types of window installation services you can get: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're still trying to decide which kind of installation you need, you can consult with your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Coventry

The EcoWatch Reviews team is different from other reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Coventry 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 the Coventry area 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 in our guide to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that give you 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 installers that have more experience 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 windows?

The typical cost to install a window can range between $450 and $650. There are a variety of factors that affect how much it costs, which include local labor costs, styles and sizes of windows, your property's location, the materials used in designing the windows, how energy-efficient the windows are and the number of windows.

What are the different kinds of windows?

The most common kinds of windows for homes are picture windows, bay windows, double-hung and single-hung windows, slider windows, awning windows, transom windows and casement windows.

Can I replace my own windows?

If you're handy and have experience with installing a replacement window, you may be able to install your own windows. But if you don't have the time or skills, we recommend hiring a professional.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
