How Installing Energy-Efficient Windows in Harpswell Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:
- Protect your investment: When you have an older home, your windows could also be outdated or leaky.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.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- More efficient energy use in your home: Because the summers can get pretty warm in Harpswell, homeowners usually rely on their air conditioner during that time. Energy-efficient windows lower the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.
- Save money on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll need less energy to heat or cool your house.
Estimated Cost of Window Replacement in Harpswell
Each window replacement company offers various services and has different price points depending on a few factors.
How Much Do New Windows Cost?
Though the average of installing one window is about $600, it can range anywhere from $200 to $1,200. This is because of the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Harpswell home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from multiple window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Harpswell, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Harpswell
In our hunt to make your home improvements easier and more eco-friendly in Harpswell, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We have assessed the best window replacement companies in Harpswell mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Harpswell, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Harpswell.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, warranty, professionalism, cost and more.
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 previously, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Harpswell, ME Window Replacement FAQs
How much does window installation cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200, based on several factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the different kinds of windows?
The most common kinds of windows for homes are slider windows, awning windows, transom windows, double-hung and single-hung windows, picture windows, bay windows and casement windows.
Can I replace my own windows?
If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or skills, we don't recommend trying it.
How long does it generally take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that have to be installed.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
