How Installing Energy-Efficient Windows in New Britain Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could help you:
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 147 pounds per year on average.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $437 a year on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
Estimated Cost of Window Replacement in New Britain
Each window installer provides varying services and has different costs depending on a few factors.
How Much Do New Windows Cost?
Typically, New Britain homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at approximately $600. How much it will cost you varies depending on several factors, such as material, the location of your home, size, number of windows, type and more.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $437 a year on your energy bills in New Britain.
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, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without taking out the entire frame, which tends to be less expensive than a full-frame installation.
Your window replacement company will be able to help you figure out what's best for your needs. In New Britain, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in New Britain
EcoWatch reviews differ from other reviews since we look at these companies through a sustainability lens. We've decided to assess the best window replacement companies in New Britain mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
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 best window installation company near you.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type 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 super important review factor is customer feedback. If most customers don't have good feedback 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 installers won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer 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 a proven track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
New Britain, CT Window Replacement FAQs
What is the typical cost to replace windows?
The national average cost of replacing one window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common types of windows for homes are transom windows, double-hung and single-hung windows, slider windows, awning windows, bay windows, picture windows and casement windows.
Can you install your own windows?
Although you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on energy costs, replacing all the windows at the same time is the only way to gain that benefit. However, if you have just a few windows that are broken or leaky, you can replace just those.
