How Installing Energy-Efficient Windows in Ashburn Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, including:

  • Save on electricity bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
  • 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: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Ashburn, that's about 376 pounds per year on average.

Estimated Cost of Window Replacement in Ashburn

Each window installer offers various services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

According to our research, the national average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. This is because window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

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. These savings vary based on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

When considering window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installation company can advise you on the best type for your project. In Ashburn, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Ashburn

The EcoWatch Reviews team is different from most reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Ashburn and ranked them based on the following methodology:

Service Area

Because this is a guide for Ashburn, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Ashburn.

Work Quality

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

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Ashburn, VA Window Replacement FAQs

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

The average cost to install one window can range between $450 and $650. There are several factors that influence the cost, which include how energy-efficient the windows are, your property's location, local labor costs, the materials used in designing the windows, styles and sizes of windows and the number of windows.

What are the most common types of replacement windows?

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

What do window installation companies do?

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

How long does it generally take to install windows?
