How Installing Energy-Efficient Windows in Wilmington Saves You Money

There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save $301 a year on your bills.
• Reduce your carbon footprint: In Wilmington, you can cut your indirect greenhouse gas emissions by about 299 pounds per year when you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Wilmington

When considering window installation, each company offers different services and prices. Let's take a look at some typical costs and services.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will make your project cost more.

It's also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Wilmington 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.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. So, instead of tearing 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.

Your window installation company will be able to advise you on the best type for your project. In Wilmington, the decision will mostly depend on how much damage there is currently and how old your existing frames are.
