Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's energy efficiency can also have a large impact on home energy conservation. During the cold winter months, the last thing you want is your heat to leak out of your drafty windows.
That's also bad for the environment because the additional energy used by damaged windows increases your carbon footprint.
We've made a guide on the best installation companies to help you in your research, so you can not only enjoy brand new windows, but also save money on your power bills.

How Installing Energy-Efficient Windows in Wilton Saves You Money
When you switch to energy-efficient windows, you may see some benefits, such as:
- Reduce your carbon footprint: In Wilton, you can cut your indirect greenhouse gas emissions by about 163 pounds per year once you switch to energy-efficient windows.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, 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.
Estimated Cost of Window Replacement in Wilton
Windows come in varying purposes, shapes and styles, so costs and services will differ greatly depending on several factors. Below, we go over the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will add extra costs to your project.
It's also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your Wilton home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Another factor that affects the overall cost is the material of the frame you choose. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window replacements, there are generally two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which increase the overall cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're unsure which type of window installation service you need, your installer can advise you. Generally, the choice is influenced by factors such as 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
EcoWatch reviews differ from other reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Wilton area so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and range 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, professionalism, warranty, cost, 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 awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Wilton's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Wilton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Wilton, ME Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a window ranges between $450 and $650. There are many factors that affect the cost, which include your property's location, how energy-efficient the windows are, styles and sizes of windows, the number of windows, local labor costs and the materials used in designing the windows.
What are the different kinds of windows?
There are several different kinds of windows you can get for your house, including awning windows, bay windows, transom windows, double-hung and single-hung windows, casement windows, picture windows and slider windows.
Can you replace your own windows?
While it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How often should you replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
