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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way.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 when you install energy-efficient windows.
  • Save on energy bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $301 annually on your energy bills in Wilmington.

Estimated Cost of Window Replacement in Wilmington

Let’s take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

Although the typical cost of replacing a single window is about $600, it can range from $200 to $1,200. But costs will vary significantly based on the current condition of your home, your location, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase overall project costs.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will typically 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 kind of window material you choose for the frames. Wood windows are typically 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 more efficient.

What Services do Window Installers Offer?

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

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window replacement company will be able to help you choose what’s best for your needs. In Wilmington, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Wilmington

EcoWatch reviews differ from other reviews because we assess these companies through a sustainability lens. We have reviewed the top window installation companies in Wilmington mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured on this list to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive feedback about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the highest quality service. Still, we want to ensure 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 considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that offer 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 water damage, low efficiency and rot. 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, DE Window Replacement FAQs

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

The national average cost to replace a single window is around $600 but can range between $200 and $1,200, depending on several factors. The price is typically influenced by the type and material of the window, the size 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 different types of windows?

There are various kinds of windows you can get for your house, including slider windows, double-hung and single-hung windows, transom windows, bay windows, awning windows, casement windows and picture windows.

What do window installers do?

Window installers travel to your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

Should I replace my windows all at once?

If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.

How long does it usually take to install windows?

Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
