Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. Potential leaks or drafts from your windows can make your AC or heater work extra hard in the summer or winter.
Installing new, efficient windows on your home can help you save money every month on your power bills — and you can help the environment, too.
Efficient windows are of particular importance in Plymouth, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $486 per year.

How Installing Energy-Efficient Windows in Plymouth Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Protect your valuables: Many Energy Star certified 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.
- More efficient energy usage in your household: In Plymouth where the winters can get very cold, energy-efficient windows reduce how much heat is lost through your windows, which makes it easier to keep your home warm.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Save money on electricity 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 Plymouth
Windows come in various styles, purposes and shapes, so costs and services will differ tremendously depending on your project. Below, we detail the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Typically, Plymouth homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
It's important to bear in mind 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 Energy Star certified windows can save Plymouth homeowners $486+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In regard to window replacements, there are generally two kinds that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
Your window installation company should be able to help you decide what's best for your needs. In Plymouth, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Plymouth
In our hunt to make your home improvements easier and more eco-friendly in Plymouth, the EcoWatch Reviews team examined many companies before settling on these. Along with energy efficiency, we reviewed several window installers in Plymouth and assigned rankings using the following methodology:
Service Area
Since this is a guide for Plymouth, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Plymouth.
Work Quality
When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers more points 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 consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, professionalism, quality of installation, warranty, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and labor 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.
Plymouth, CT Window Replacement FAQs
How much does a window install cost?
The average cost to install one window ranges from $450 to $650. There are many factors that affect the price, such as your property's location, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs and styles and sizes of windows.
Which type of window should I get?
A window's energy efficiency is affected by 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.
When should I use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved 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 safer option.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the 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.
