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 consider making the switch:
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Save on power bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, the switch can help you save around $441 annually on your energy bills in Wilton.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.
Estimated Cost of Window Replacement in Wilton
Each window replacement company offers various services and has different prices depending on several factors.
How Much Do New Windows Cost?
Although the average cost of replacing a single window is around $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, like the location of your home, material, type, size, number of windows and more.
It’s also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Wilton home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re still trying to decide which kind of installation you need, you can talk to your provider and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage present.

We’ve decided to evaluate the best window replacement companies in Wilton primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
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
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured 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
Customer feedback is another super important review factor. If the majority of customers don’t have positive things to say about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the highest 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 significant investment, so you’ll want to make sure that investment is 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 been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Wilton, CT Window Replacement FAQs
How much does window installation cost?
The average cost of installing a window can range from $450 to $650. There are several factors that affect how much it costs, including the number of windows, your property’s location, local labor costs, how energy-efficient the windows are, styles and sizes of windows and the materials used in designing the windows.
What are the kinds of windows?
The most common kinds of windows for homes are bay windows, picture windows, casement windows, transom windows, double-hung and single-hung windows, slider windows and awning windows.
When do I have to use a window installation company?
You should hire a window installation company whenever you need to replace your windows. Installing windows is a involved process that can be difficult to do on your own, so it’s best handled by the professionals.
How often should you replace windows?
Windows usually last about 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have them looked at by an expert to determine if they are in need of a repair or replacement.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
