How Installing Energy-Efficient Windows in Wilmington Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to make the switch:
- Save on energy bills: Because energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save about $464 annually on your energy bills in Wilmington.
- Decrease your carbon footprint: In Wilmington, you can cut your indirect greenhouse gas emissions by about 139 pounds per year after you install energy-efficient windows.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Wilmington
When looking into window installation, each company offers varying services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the national average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. These numbers are based on the specifics of your installation, including number of windows, material, size, the location of your home, type and more.
It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Wilmington homeowners $464+ a year when replacing single-pane windows.
Getting free quotes from several providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step when considering a window installation is to decide whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations are simpler and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window replacement company will be able to help you figure out what’s best for your needs. In Wilmington, the decision will mostly be based on how old your home is and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Wilmington
In our search to find the most reliable, eco-friendly window installers in Wilmington, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We’ve reviewed the best window installers in Wilmington primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. 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
Since this is a guide for Wilmington, we only included companies that serve the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Wilmington.
Work Quality
When selecting new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do rate window installers higher 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 most customers don’t have nice things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Wilmington, MA Window Replacement FAQs
What is the average cost to install new windows?
The average cost of installing one window ranges between $450 and $650. There are many factors that influence the cost, which include local labor costs, the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows, the number of windows and your property’s location.
Which kind of window should I get?
A window’s energy efficiency is affected by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
You should hire a window installation professional whenever you want new windows. Installing windows is a complex process that can take a lot of time, so it’s best handled by the professionals.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all of the windows together is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
How long does window installation usually take?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
