How Installing Energy-Efficient Windows in New Castle Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, including:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In New Castle, that’s about 154 pounds per year on average.
Estimated Cost of Window Replacement in New Castle
Let’s take a look at the cost of window replacement and the kinds of services offered by installers.
How Much Do New Windows Cost?
On average, homeowners in New Castle can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost varies depending on several factors, such as number of windows, type, the location of your home, material, size and more.
It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your New Castle home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by switching to 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 based on the kind of material you choose for the frames. Wood windows are generally the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When considering window installations, in general there are two types that your installer will offer: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. 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. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without taking out the entire frame, which is generally less expensive than a full-frame installation.
Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in New Castle
The EcoWatch Reviews team differs from most reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in New Castle and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the New Castle area so you can find a quality window installation company near you.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, cost, professionalism, quality of parts, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that provide 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 a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn’t be raining, as rain can make the installation more difficult.
How do you know it’s time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
