How Installing Energy-Efficient Windows in South Berwick Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Better temperature control in your home: When you reside in a city like South Berwick where the summers can be pretty warm, you often need to rely on your air conditioner to keep your home cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
Estimated Cost of Window Replacement in South Berwick
When looking into window installation, each company provides different services and costs. Let's go over some average costs and services.
How Much Do New Windows Cost?
Although the national average to install one window is about $600, it can range anywhere from $200 to $1,200. These numbers vary based on the specifics of your installation, including size, type, the location of your home, material, number of windows and more.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Getting free quotes from multiple companies is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has considerable deterioration. Full-frame installations are more involved and will increase the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In South Berwick, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in South Berwick
EcoWatch reviews are different from most reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in South Berwick and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the South Berwick area so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, quality of parts, warranty, professionalism, quality of installation and more.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a range 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 give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to South Berwick's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of South Berwick window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
South Berwick, ME Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost of replacing a single window ranges between $450 and $650. There are several factors that affect how much it costs, including the materials used in designing the windows, local labor costs, styles and sizes of windows, the number of windows, how energy-efficient the windows are and your property's location.
Which type of window should I get?
A window's energy efficiency is affected by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
You should use a window installation company whenever you want to replace your windows. Installing windows is a involved process that can take a lot of time, so it's best left to the professionals.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. 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 isn't necessarily a big factor. What's most important is that the weather should be dry.
