How Installing Energy-Efficient Windows in Plymouth Saves You Money
When you switch to energy-efficient windows, you may see several perks, including:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
- Save on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Plymouth
When researching window installation, each company offers different services and costs. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
Though the typical cost of replacing a single window is about $600, it can range from $200 to $1,200. But costs will differ considerably based on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Plymouth homeowners $486+ a year after replacing single-pane windows.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering an installation is to clarify whether you want a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.
If you’re not sure which type of window installation service you need, your installer should be able to assist you. In general, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Plymouth
In our search to find the most reliable, eco-friendly window installers in Plymouth, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We have reviewed the top window replacement companies in Plymouth 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 cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Plymouth area so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have good feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide 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 have 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 good track record in the industry. Window installation companies that have more years of experience are going to 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 typical cost to replace a single window can range from $450 to $650. There are several factors that affect how much it costs, which include the number of windows, how energy-efficient the windows are, the materials used in designing the windows, your property’s location, local labor costs and styles and sizes of windows.
What are the most common types of replacement windows?
There are several different kinds of windows you can get for your home, including picture windows, slider windows, awning windows, casement windows, double-hung and single-hung windows, transom windows and bay windows.
What services do window replacement companies provide?
Window installation professionals will do the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. Additionally, many companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, 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 house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
