Why you can trust EcoWatch

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.

Although green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house’s energy efficiency can also have a large impact on home energy conservation. Potential leaks or drafts can lower your home’s energy efficiency by up to 30%, according to the Department of Energy. In Montville, that’s an average of $424 a year that you could save on your electricity bills after making the switch.

Installing efficient windows on your property can help you save money every month on your electric bills — and you can help the environment as well.

Unlike other review sites, EcoWatch ranks window replacement companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Montville Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to think about making the switch:

  • Decrease your carbon footprint: In Montville, you can lower your indirect greenhouse gas emissions by about 147 pounds per year once you upgrade to energy-efficient windows.
  • Save money on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Montville

Each window replacement company provides varying services and has varying prices based on a few factors.

How Much Do New Windows Cost?

Though the national average cost to replace one window is around $600, it can range from $200 to $1,200. How much it will cost is based on several factors, like size, number of windows, material, type, the location of your home and more.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $424 a year on your energy bills in Montville.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your installers will replace the entire window, including the frame, trim and sill. Pocket installations are simpler and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re still debating which kind of installation to get, you can talk to your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Montville

In our search to find the most reliable, eco-friendly window installers in Montville, the EcoWatch team evaluated many companies before landing on these. We’ve decided to evaluate the best window installers in Montville primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower energy 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 installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, cost, quality of installation, warranty, quality of parts and more.

Cost

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

Warranty

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

Years of Experience

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

Montville, CT Window Replacement FAQs

What is the typical cost to install windows?

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

What kind of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be 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.

Can you install your own windows?

Even though you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

What time of year is the best time to replace my 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 harder.

How long does window installation typically take?

Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
