How Installing Energy-Efficient Windows in Reston Saves You Money

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

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Reston, that’s about 376 pounds per year on average.
• 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 fading of your furniture, carpet and other valuables.
• Save on power bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.

Estimated Cost of Window Replacement in Reston

Let’s go over the cost of replacing your windows and the types of services offered by installers.

How Much Do New Windows Cost?

Generally, homeowners in Reston can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost depends on several factors, like the location of your home, number of windows, type, material, size and more.

It’s also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Reston home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

In general, there are two types of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

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

How We Choose the Best Window Installers in Reston

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

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Reston area so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have nice feedback about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like 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 previously, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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