How Installing Energy-Efficient Windows in Wilton Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to make the switch:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Better temperature control in your home: When you live in a city like Wilton where the winters can get cold, you usually need to depend on your heater to keep your house warm. Energy-efficient windows can decrease how hard your heater needs to work to heat your home.
- Better temperature control in your home: Residing in a warm city like Wilton can often mean needing your AC to keep your house cool. Energy-efficient windows can reduce the amount of cool air lost through your windows when cooling your home.
- Reduce your carbon footprint: In Wilton, you can reduce your indirect greenhouse gas emissions by about 65 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Wilton
Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and the primary services that you'll find from window installers.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range from $200 to $1,200. This is because window installations are based on several 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 keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Wilton homeowners $386+ a year when replacing single-pane windows.
The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In regard to window installations, there are generally two types that your provider will have: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage. Because full-frame installations are more involved, they will raise the total cost. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
Your window installation company will be able to help you understand what's best for your needs. In Wilton, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Wilton
EcoWatch is different from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Wilton and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Wilton so you can find the best 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 company in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, quality of parts, professionalism, cost, quality of installation and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Wilton's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Wilton window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
