How Installing Energy-Efficient Windows in Wilmington Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to consider making the switch:

  • 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 money on electricity bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $464 annually on your energy bills in Wilmington.
  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Wilmington

Let's take a look at the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

Generally, Wilmington homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. But prices differ considerably 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 offer door installations, which will add extra costs to your project.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $464 a year on your energy bills in Wilmington.

Another factor that affects the overall cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has a lot of deterioration. With this service, your professionals will replace the entire window, including the trim, sill and frame. Pocket installations are simpler and won't carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

Your window installation company should be able to help you choose what's best for your needs. In Wilmington, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Wilmington

EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve the Wilmington area so you can find a quality 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 make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, professionalism, cost, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a significant 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

Because of Wilmington's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Wilmington window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Wilmington, MA Window Replacement FAQs

What is the average cost to install windows in a home?

The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually dependent on the size of the window, the type and material 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 are the types of windows?

The most common types of windows for homes include: transom windows, bay windows, casement windows, slider windows, awning windows, double-hung and single-hung windows and picture windows.

Can I install my own windows?

While you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.

How long does it generally take to install windows?

Since the average installation time is 30 minutes per window, about 16 windows can be installed in a typical 8-hour work day.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows at once is the only way to gain that benefit. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
