How Installing Energy-Efficient Windows in Kittery Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:
- Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Save money on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $383 annually on your energy bills in Kittery.
Estimated Cost of Window Replacement in Kittery
When researching window installation, each company provides different services and prices. Let’s look at some average costs and services.
How Much Do New Windows Cost?
According to our research, the typical cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost varies based on several factors, like type, number of windows, size, the location of your home, material and more.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also provide 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 require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the frame that’s already there. So, instead of taking out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Kittery, the choice will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Kittery
In our hunt to make your home improvements easier and more eco-friendly in Kittery, EcoWatch examined many companies before landing on these. We’ve evaluated the best window installers in Kittery mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can 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 Kittery, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Kittery.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company included on this list to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have positive things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies won’t always provide the most quality service. On the other hand, 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
As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Kittery, ME Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a single window can range from $450 to $650. There are many factors that affect the price, which include styles and sizes of windows, the number of windows, local labor costs, the materials used in designing the windows, how energy-efficient the windows are and your property’s location.
Which kind of window should I get?
A window’s energy efficiency is affected by several factors, including 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 need new windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best handled by the professionals.
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. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
