How Installing Energy-Efficient Windows in Groton Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Reduce your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Groton
Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
On average, homeowners in Groton can expect that most replacement window installations will range from $250 to $1,200, with the average cost at around $600. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Groton homeowners $424+ per year after replacing single-pane windows.
Another factor that influences the total cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves installing a new window within the frame that’s already there. So, instead of removing the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to advise you on the best type for your project. In Groton, the choice will mostly be influenced by the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Groton
EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We’ve decided to review the best window installation companies in Groton primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Groton, we gave more points to companies that serve the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Groton.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, warranty, professionalism, quality of installation, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Groton, CT Window Replacement FAQs
How much does a window install cost?
The average cost to install one window ranges between $450 and $650. There are many factors that influence how much it costs, such as the materials used in designing the windows, your property’s location, the number of windows, local labor costs, how energy-efficient the windows are and styles and sizes of windows.
Which type of window should I get?
A window’s energy efficiency is affected by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installers do?
Window installers cover the entire process — from replacing old windows with new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.
How often should you replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
