How Installing Energy-Efficient Windows in Griswold Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Better temperature control in your home: Living in a very cold place like Griswold usually means depending on your heater to keep your house cool. Energy-efficient windows can lower how hard your heating system needs to work to heat your home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Save money on energy 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 lower how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Griswold
Each window installation company provides varying services and has different costs based on several factors.
How Much Do New Windows Cost?
On average, homeowners in Griswold can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost you varies based on several factors, such as number of windows, size, type, material, the location of your home and more.
It's important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Griswold homeowners $424+ a year when replacing single-pane windows.
Asking for free quotes from several installers 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 replacement services: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the entire window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Griswold
In our search to find the most reliable, eco-friendly window installers in Griswold, the EcoWatch Reviews team examined dozens of companies before deciding on these. We've reviewed the best window replacement companies in Griswold mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your power 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 the Griswold area so you can find the best window installation company near you.
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 in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent 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 installation, professionalism, quality of parts, warranty, cost and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the highest quality service. On the other hand, 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer 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 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.
Griswold, CT Window Replacement FAQs
What is the average cost to replace windows?
The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is typically influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window's energy efficiency depends on a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Do you really need to use a window installation company?
Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.
What time of year should I replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
