How Installing Energy-Efficient Windows in Scarborough Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could benefit you:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce that number, 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 because of their ability to filter out harmful UV rays.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Scarborough, that’s about 163 pounds per year on average.
Estimated Cost of Window Replacement in Scarborough
Let’s go over the cost of updating your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Although the national average cost to install a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, like size, type, material, the location of your home, number of windows 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 $396 a year on your energy bills in Scarborough.
Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services you can get: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end 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 installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Scarborough
EcoWatch differs from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Scarborough and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Scarborough so you can find the best window installation company near you.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their service from a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Scarborough’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Scarborough window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Scarborough, ME Window Replacement FAQs
What is the typical cost to replace windows in a home?
The average cost to install a window can range from $450 to $650. There are a variety of factors that influence how much it costs, such as how energy-efficient the windows are, your property’s location, local labor costs, the materials used in designing the windows, the number of windows and styles and sizes of windows.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
Can you replace your 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 experience, we recommend getting a professional to do it for you.
Should I replace my windows all at the same time?
If you’re upgrading your windows to get more efficient windows, replacing all of the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
