How Installing Energy-Efficient Windows in Reston Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Reston, that's about 376 pounds per year on average.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Reston
Each window installation company provides various services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
According to our research, the typical cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. These estimates vary depending on specific characteristics of your installation, like size, type, number of windows, material, the location of your home and more.
Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Asking for free quotes from multiple installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the frame, trim and sill. You most likely need a full-frame installation when you want a new style or your window has significant deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation entails installing a new window without replacing the frame. So, instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company should be able to help you choose what's best for your needs. In Reston, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Reston
In our hunt to find the most reliable, eco-friendly window installers in Reston, the EcoWatch team assessed many companies before settling on these. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Reston, we paid more attention to companies that serve 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 Reston.
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 on this list to ensure 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 good things to say about their experience with a certain installer, you won't see it 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. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that provide 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 installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Reston, VA Window Replacement FAQs
How much should window installation cost?
The national average cost of installing one window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Do you really need to use a window installation company?
You should use a window installation company whenever you need new windows. Installing windows is a complicated process that can take a lot of time, so it's best handled by the professionals.
How often do you need to replace your windows?
Windows usually have a lifespan of about 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them looked at by an expert to see if they are in need of a repair or replacement.
Should I replace my windows all at once?
If you're upgrading your windows to save on your energy bills, replacing all the windows at the same time is the only way to gain that benefit. However, if you have only a few windows that are damaged or drafty, you can replace just those.
