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.

Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's energy efficiency can also have a large impact on home energy conservation. According to the Department of Energy, heat gained or lost through traditional, outdated windows could make up 25-30% of residential energy climate control usage.

Installing efficient windows on your house can help you save money each month on your electricity bills — and you can help the environment, too.

Efficient windows are of particular importance in Wilton, where winters are long and cold. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $384 a year.

How Installing Energy-Efficient Windows in Wilton Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to consider making the switch:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
  • Decrease your carbon footprint: In Wilton, you can cut your indirect greenhouse gas emissions by about 152 pounds per year once you upgrade to energy-efficient windows.
  • Save money on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Wilton

Windows come in various shapes, styles and purposes, so costs and services will differ tremendously based on your project. Below, we detail the typical cost and services that you'll find from window installers.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations depend 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.

It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Wilton homeowners $384+ a year when replacing single-pane windows.

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

What Services do Window Installers Offer?

The first step of a window replacement is to clarify whether you want a full-frame or pocket installation.

A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation means replacing a window without removing the complete frame, which is usually less expensive than a full-frame installation.

If you're not sure which type of window installation service you need, your installer should be able to assist you. Generally, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Wilton

In our hunt to make your home improvements easier and more eco-friendly in Wilton, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We have decided to evaluate the best window installers in Wilton primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your power 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 installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, quality of parts, cost, warranty, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher points 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Wilton, NH Window Replacement FAQs

How much does window installation cost?

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

Which kind of window should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

If you're handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don't have the time or know-how, we don't recommend doing it on your own.

How long does it typically take to install windows?

Since the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.

Should I replace my windows all at once?

If you're upgrading your windows to get more efficient windows, replacing all your windows together is the only way to gain that benefit. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
