How Installing Energy-Efficient Windows in Greenbelt Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, including:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 249 pounds per year on average.

Estimated Cost of Window Replacement in Greenbelt

Each window installer provides varying services and has different price points depending on a few factors.

How Much Do New Windows Cost?

Generally, Greenbelt homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost you varies depending on several factors, like number of windows, the location of your home, size, material, type and more.

Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Getting free quotes from multiple providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the total window, including the sill, trim and frame. A pocket installation entails installing a new window within the old frame. This means instead of taking out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Greenbelt

In our hunt to make your home improvements easier and more eco-friendly in Greenbelt, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Greenbelt, we only included companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Greenbelt.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

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

Greenbelt, MD Window Replacement FAQs

How much should window installation cost?

The national average cost of installing 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 upfront but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

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

What do window installers do?

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

How long does window installation take?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed during a typical 8-hour work day.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
