20 Best Window Companies in Gorham, ME (2025 Reviews)

How Installing Energy-Efficient Windows in Gorham Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:

• Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Many window companies also provide door installations and replacements, which will make your project cost more.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $396 a year on your energy bills in Gorham.

Getting free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

The first step when considering a window replacement is to clarify whether you want a full-frame or pocket installation.

A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company should be able to help you decide what’s best for your needs. In Gorham, the decision will mostly depend on the age of your home 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 Gorham

In our search to find the most reliable, eco-friendly window installers in Gorham, EcoWatch examined dozens of companies before landing on these. We’ve reviewed the best window installers in Gorham mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Gorham, we only included companies that cover the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Gorham.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of installation, quality of parts, warranty, professionalism and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Gorham’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Gorham window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
