How Installing Energy-Efficient Windows in Delaware Saves You Money

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

  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Reduce your carbon footprint: In Delaware, you can lower your indirect greenhouse gas emissions by about 206 pounds per year after you install energy-efficient windows.

Estimated Cost of Window Replacement in Delaware

Let's go over the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

According to our research, the average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost you varies depending on several factors, including number of windows, material, type, the location of your home, size and more.

It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Delaware homeowners $264+ a year when replacing single-pane windows.

Another factor that affects the overall cost is the material you pick for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as 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?

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

Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the entire window, including the sill, frame and trim. 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 or rot, you may have to get a full-frame installation instead.

Your window installer should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Delaware

EcoWatch is different from most reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Delaware area so you can find the right 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 installer in our guide to make sure its technicians 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 good things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Delaware, NJ Window Replacement FAQs

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

The typical cost of replacing a window can range from $450 to $650. There are many factors that affect how much it costs, including the number of windows, local labor costs, your property's location, how energy-efficient the windows are, styles and sizes of windows and the materials used in designing the windows.

What are the kinds of windows?

There are several different types of windows you can get for your home, including casement windows, awning windows, double-hung and single-hung windows, picture windows, bay windows, slider windows and transom windows.

What services do window replacement companies offer?

Window installation companies cover the entire process — from replacing old windows with brand new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.

How often do you need to replace your windows?

Windows usually last around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them looked at by an expert to determine if they are in need of a repair or replacement.

Should I replace all my windows at once?

If your windows are greater than 20 years old, you probably 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.
