Calculate how much you can expect to pay for window installation and replacement in Claymont, DE using our customized window cost calculator.

How Installing Energy-Efficient Windows in Claymont Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- More efficient energy use in your household: Because the summers can get quite hot in Claymont, homeowners usually rely on their air conditioner a lot. Energy-efficient windows decrease the amount of cool air that is lost through your windows, making it easier to keep your home cool.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. 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 Claymont
Windows come in different styles, shapes and purposes, so costs and services will vary greatly based on your project. Below, we detail the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
On average, homeowners in Claymont can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at around $600. This is due to the fact that window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your Claymont home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from multiple providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two types 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 windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you figure out what's best for your needs. In Claymont, the decision will mostly be based on how old your windows are 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 examine your frames and window sills.

How We Choose the Best Window Installers in Claymont
In our search to find the most reliable, eco-friendly window installers in Claymont, EcoWatch landed on the above companies as the best window installation companies in the city. We've reviewed the best window replacement companies in Claymont mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Claymont, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Claymont.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a hefty investment, so you'll want to be certain that investment is protected. 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.
Claymont, DE Window Replacement FAQs
How much should a window install cost?
The national average cost to install one window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
You should hire a window installation company whenever you need to replace your windows. Installing windows is a involved process that can be difficult to do on your own, so it's best handled by the professionals.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, it shouldn't be raining, since rain can make the installation harder.
