Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a considerable impact on home energy conservation. The Department of Energy estimates that heat or cool air lost through outdated or drafty windows could represent about 30% of residential energy climate usage. In Delaware, where the electric bills are an average of $41 per month, that's almost $$149 per year wasted.

That's also bad news for the environment, as the extra energy used by drafty windows increases your carbon footprint.

Unlike other sites, EcoWatch ranks window replacement companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Delaware Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:

  • Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient windows can help decrease that number, which helps you save $310 a year on your bills.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Delaware, that's about 525 pounds per year on average.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Delaware

Windows come in varying purposes, shapes and styles, so costs and services will vary considerably depending on several factors. Below, we go over the average cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range anywhere from $200 to $1,200. These amounts vary based on specific characteristics of your installation, including material, size, type, the location of your home, number of windows and more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want to change the style of your windows or your window has significant deterioration. With this service, your professionals will replace the whole window, including the trim, frame and sill. Pocket installations are on the simpler end and won't cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Delaware, the choice will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Delaware

In our search to make your home improvements easier and more eco-friendly in Delaware, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Delaware and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Delaware, we only included companies that serve the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Delaware.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, warranty, quality of installation, professionalism, quality of parts and more.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Delaware, OH Window Replacement FAQs

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

The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally dependent on the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What type of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you're handy and have the time to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.

How often should you replace windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at once?

If you're upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to gain that benefit. However, if you have only one or two windows that are broken or drafty, you can replace just those.
