How Installing Energy-Efficient Windows in Wilmington Manor Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could help you:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 299 pounds per year on average.
- Save money on energy bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save around $301 annually on your energy bills in Wilmington Manor.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
Estimated Cost of Window Replacement in Wilmington Manor
When looking into window installation, each company offers different services and costs. Let's go over some average costs and services.
How Much Do New Windows Cost?
Generally, Wilmington Manor homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at around $600. This is because window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Wilmington Manor homeowners $301+ a year after replacing single-pane windows.
The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, but 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?
Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. This means instead of taking out the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're not sure which type of window installation service you need, your installer should be able to advise you. In general, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Wilmington Manor
In our search to find the most reliable, eco-friendly window installers in Wilmington Manor, EcoWatch assessed dozens of companies before settling on these. Along with energy efficiency, we analyzed several window installers in Wilmington Manor and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities 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 company in our guide to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, professionalism, quality of installation, warranty, cost and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a sizable investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Wilmington Manor's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Wilmington Manor window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Wilmington Manor, DE Window Replacement FAQs
How much does a window install cost?
The typical cost to install a single window ranges between $450 and $650. There are many factors that affect how much it costs, such as how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows, the number of windows, your property's location and local labor costs.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don't have the time or know-how, we don't recommend doing it on your own.
How often do you need to replace your windows?
Windows generally have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to see if they need any repairs or replacements.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all the windows at once is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or leaky, you can replace just those.
