How Installing Energy-Efficient Windows in Wilmington Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, including:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- More efficient energy use in your home: Because the winters can get very cold in Wilmington, homeowners usually rely on their heater a lot. Energy-efficient windows reduce the amount of heat that is lost through your windows, making it easier to keep your home warm.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Wilmington
When looking into window installation, each company provides varying services and costs. Let's look at some typical costs and services.
How Much Do New Windows Cost?
According to our research, the average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. But costs will vary considerably based on the current condition of your home, your location, the quality of your products and the number of windows you need. Many window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.
It's also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Wilmington home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step of a window replacement is to decide whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the complete window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has significant rot. Because full-frame installations are more involved, they will raise the overall cost. A pocket installation entails installing a new window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Wilmington
EcoWatch is different from most reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Wilmington area so you can find the right window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, quality of parts, quality of installation, professionalism, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the highest 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 to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Wilmington's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Wilmington window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Wilmington, MA Window Replacement FAQs
How much does a window install cost?
The average cost to install a window can range from $450 to $650. There are several factors that affect the cost, such as the number of windows, the materials used in designing the windows, styles and sizes of windows, your property's location, local labor costs and how energy-efficient the windows are.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Do I really have to 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 window installation process is complicated and can take anywhere from four to six hours for a single 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 alternative.
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 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.
