Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a large impact on home energy conservation. If your windows are drafty or damaged, you could be losing 25-30% of your home's heat or cool air out of them.
That's bad for both your bank account and the environment, but one of the top window installation companies can help you with that.
Efficient windows are of particular importance in Norwich, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $424 a year.

How Installing Energy-Efficient Windows in Norwich Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Norwich, that's about 147 pounds per year on average.
- Save on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- 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 due to their ability to filter out harmful UV rays.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Norwich
Windows come in varying shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you'll find from the average window installation company.
How Much Do New Windows Cost?
The national average cost to install one 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, such as the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star estimates that upgrading the windows on your Norwich home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each 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.
Getting free quotes from several providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which increase the total 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 should opt for a full-frame installation instead.
Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Norwich
The EcoWatch Reviews team is different from other reviewers because we look at these companies through a sustainability lens. We've assessed the best window installers in Norwich primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Norwich, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Norwich.
Work Quality
When choosing new windows, the quality and breadth of services can often play 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 consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you 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 been in the industry for a while. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Norwich, CT Window Replacement FAQs
What is the average cost to replace windows in a home?
The average cost of replacing one window ranges from $450 to $650. There are a variety of factors that influence the price, which include the materials used in designing the windows, your property's location, how energy-efficient the windows are, local labor costs, the number of windows and styles and sizes of windows.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your home, such as slider windows, double-hung and single-hung windows, awning windows, bay windows, transom windows, casement windows and picture windows.
Can I install my own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. But if you don't have the time or skills, we don't recommend doing it on your own.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, it shouldn't be raining, since rain can make the installation more difficult.
How often do you need to replace windows?
Windows typically last about 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them looked at by an expert to see if they are in need of a repair or replacement.
