How Installing Energy-Efficient Windows in Wilmington Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
• Reduce your carbon footprint: In Wilmington, you can reduce your indirect greenhouse gas emissions by about 299 pounds per year once you install energy-efficient windows.
• Save money on energy bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save about $301 annually on your energy bills in Wilmington.

Estimated Cost of Window Replacement in Wilmington

When looking into window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. This is due to the fact that window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $301 a year on your energy bills in Wilmington.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether 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?

In regard to window installations, there are typically two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations require more time and labor and will increase overall costs. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

If you’re still trying to decide which kind of installation you should get, you can consult with your installer and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Wilmington

EcoWatch is different from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Wilmington and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, quality of installation, professionalism, cost, quality of parts and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

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.

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
