Why you can trust EcoWatch
Whether you're doing renovations or have windows that need repairs, windows play a vital role in conserving your home's electricity. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could make up about 30% of heating and cooling usage. In Topsham, where the electricity bills are an average of $30 per month, that's almost $$108 per year wasted.
That's also bad news for the environment, as the extra energy required by leaky windows increases your carbon footprint.
Efficient windows are of particular importance in Topsham, where winters are long and cold. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $387 a year.

How Installing Energy-Efficient Windows in Topsham Saves You Money
When you upgrade to energy-efficient windows, you may see a few benefits, such as:
- Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Topsham, that's about 163 pounds per year on average.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Topsham
Let's take a look at the cost of window replacement and the kinds of services offered by installers.
How Much Do New Windows Cost?
According to our market research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost you varies depending on several factors, such as the location of your home, type, number of windows, material, size and more.
It's also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your Topsham home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. 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?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has noticeable rot or deterioration. Because full-frame installations are more involved, they will raise the total cost. A pocket installation entails installing a new window within the old frame. So, instead of taking out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can recommend the best type for your project. In Topsham, the choice will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Topsham
In our hunt to make your home improvements easier and more eco-friendly in Topsham, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Topsham, we only included companies that cover the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Topsham.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer included on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of installation, quality of parts, cost and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the highest quality service. Still, we want to ensure 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 that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Topsham's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Topsham window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Topsham, ME Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost of replacing a single window can range between $450 and $650. There are a variety of factors that influence how much it costs, including styles and sizes of windows, the number of windows, local labor costs, the materials used in designing the windows, your property's location and how energy-efficient the windows are.
What type of window is the most energy-efficient?
A window's energy efficiency depends on a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can you replace your own windows?
While you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
How often do you need to replace windows?
Windows have an average 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.
