How Installing Energy-Efficient Windows in Greenbelt Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could help you:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing 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 value, especially if your home is on the older side.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Greenbelt

Windows come in various purposes, shapes and styles, so costs and services will vary greatly based on several factors. Below, we go over the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

Typically, homeowners in Greenbelt can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. Costs will differ considerably based on the number of windows you need, the quality of your products, the current condition of your home and your location. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.

It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Greenbelt homeowners $283+ a year when replacing single-pane windows.

Requesting free quotes from multiple companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two kinds that your provider will offer: full-frame and pocket installations.

A full-frame installation replaces the total window, such as 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 (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re unsure which kind of window installation service you need, your installer can assist you. Typically, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Greenbelt

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

Service Area

Because this is a guide for Greenbelt, 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 Greenbelt.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have positive things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Greenbelt, MD Window Replacement FAQs

What is the typical cost to install windows?

The national average cost to replace a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is often influenced by the location of your property, the type and material of the window and the size 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.

Which type of window should I get?

A window’s energy efficiency is influenced by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installers do?

Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

How do you know it’s time to replace your windows?

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