How Installing Energy-Efficient Windows in Potomac Mills Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, including:

  • Save money on power bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save about $360 annually on your energy bills in Potomac Mills.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Potomac Mills, that's about 376 pounds per year on average.
  • More efficient energy usage in your household: Because the summers can get quite hot in Potomac Mills, homeowners usually rely on their air conditioner a lot. Energy-efficient windows cut back on the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.

Estimated Cost of Window Replacement in Potomac Mills

Let's take a look at the cost of replacing your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range from $200 to $1,200. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will add extra costs to your project.

It's also worth noting that energy-efficient windows will typically cost more initially, but Energy Star predicts that switching out the windows on your Potomac Mills home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Another factor that affects the overall cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In regard to window replacements, there are typically two kinds that your provider will have: full-frame and pocket installations.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

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 Potomac Mills, the decision will mostly be based on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Potomac Mills

EcoWatch reviews are different from other reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Potomac Mills and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve the Potomac Mills area so you can find the right window installation company near you.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. 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 patterns in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, quality of parts, professionalism, cost, warranty and more.

Cost

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

Warranty

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Potomac Mills' climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Potomac Mills window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Potomac Mills, VA Window Replacement FAQs

What is the typical cost to install windows?

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

Which kind of window should I get?

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

What services do window replacement companies do?

Window installation companies will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, many companies offer window manufacturing, customization and repairs.

Should I replace all my windows at once?

If you're upgrading your windows to get more efficient windows, replacing all of your windows at the same time is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or leaky, you can replace just those.
