How Installing Energy-Efficient Windows in Wilmington Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
• 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.
• Decrease your carbon footprint: By using less energy after you switch to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
• Save on energy bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $234 annually on your energy bills in Wilmington.

Estimated Cost of Window Replacement in Wilmington

Windows come in different purposes, styles and shapes, so costs and services will differ tremendously depending on several factors. Below, we describe the typical cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

According to our market research, the typical cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. But costs will differ considerably based on the quality of your products, your location, the current condition of your home and the number of windows you need. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.

It’s also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star predicts that switching out the windows on your Wilmington home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Requesting free quotes from multiple installers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

The first step when considering a replacement is to clarify whether you need a full-frame or pocket installation.

A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails installing a new window without replacing the frame. This means instead of tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to recommend the best type for your project. In Wilmington, the decision will mostly be based on the efficiency of your home and the condition of your existing frames.

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Wilmington so you can find the best 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 featured in our guide to ensure its technicians are well-qualified and that the company has received lots 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 may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, professionalism, quality of parts, warranty, cost and more.

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Wilmington’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 window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
