How Installing Energy-Efficient Windows in Gray Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- More efficient energy use in your home: Because the summers can get pretty warm in Gray, homeowners usually depend on their air conditioner a lot. Energy-efficient windows lower how much cool air is lost through your windows, making it easier to keep your home cool.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- More efficient energy usage in your household: Because the winters can get cold in Gray, homeowners usually depend on their heater a lot. Energy-efficient windows lower how much heat is lost through your windows, which makes it easier to keep your house warm.
Estimated Cost of Window Replacement in Gray
Let's go over the cost of installing new windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
Generally, Gray homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at approximately $600. Costs will vary significantly depending on your location, the quality of your products, the current condition of your home and the number of windows you need. Many window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase your overall project costs.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
We recommend getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company should be able to help you understand what's best for your needs. In Gray, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Gray
EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Gray area so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation 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
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of installation, warranty, professionalism, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Gray, ME Window Replacement FAQs
How much does window installation cost?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is typically influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Do you really need to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring the pros. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.
How long does window installation generally take?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then 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.
