How Installing Energy-Efficient Windows in Gorham Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Better temperature control in your home: Living in a warm place like Gorham can often mean relying on your air conditioner to keep your home cool. Energy-efficient windows can cut back on the amount of cool air lost through your windows when cooling your home.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient windows can help decrease that amount, which helps you save $396 a year on your bills.
Estimated Cost of Window Replacement in Gorham
Windows come in all shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Typically, Gorham homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at approximately $600. These figures are based on the specifics of your installation, such as number of windows, type, the location of your home, size, material and more.
It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Gorham homeowners $396+ a year when replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering a window installation is to decide whether you need a full-frame or pocket installation.
A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
Your window installation company should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Gorham
In our hunt to find the most reliable, eco-friendly window installers in Gorham, EcoWatch examined dozens of companies before landing on these. We've evaluated the best window installation companies in Gorham mainly 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 lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Gorham, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Gorham.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its contractors 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 most customers don't have positive feedback about their service from a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies with 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 proven track record in the industry. 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.
Gorham, ME Window Replacement FAQs
How much should window installation cost?
The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
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. If you want to be sure you'll have 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.
When should I use a window installation company?
Unless you're handy and have the time needed to replace your own windows, we recommend hiring a professional. The window installation process is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.
How long does it usually take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
