How Installing Energy-Efficient Windows in Chantilly Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:

  • More efficient energy usage in your household: Because the summers can get quite hot in Chantilly, homeowners usually depend on their air conditioner a lot. Energy-efficient windows cut back on the amount of cool air that is lost through your windows, making it easier to keep your home cool.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Chantilly, that's about 376 pounds per year on average.
  • 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.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $359 a year on your bills.

Estimated Cost of Window Replacement in Chantilly

Windows come in various shapes, styles and purposes, so costs and services will differ tremendously based on your project. Below, we go over the average cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.

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 depending on your local climate, energy rates and individual home characteristics.

We advise getting free quotes from multiple window installers to find the one that works best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want a new style or your window has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations are on the simpler end and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

If you're still debating which type of installation you should get, you can consult with your provider and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Chantilly

EcoWatch reviews are different from other reviews since we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Chantilly and ranked them based on the following methodology:

Service Area

Because this is a guide for Chantilly, we only included companies that cover the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Chantilly.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, cost, quality of installation, warranty and more.

Cost

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

Warranty

As discussed, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that give you 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 quite some time. 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.
