Calculate how much you can expect to pay for window installation and replacement in Reston, VA using our customized window cost calculator.
Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.
How Installing Energy-Efficient Windows in Reston Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Reston, that's about 376 pounds per year on average.
- More efficient energy use in your home: In Reston where the summers can get quite hot, energy-efficient windows reduce the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.
- Better temperature control in your home: Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
Estimated Cost of Window Replacement in Reston
Each window installer offers varying services and has different price points based on a few factors.
How Much Do New Windows Cost?
Although the average to replace one window is about $600, it can range from $200 to $1,200. But prices 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 offer door installations, which have a higher price tag.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $359 a year on your energy bills in Reston.
The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations involve replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot. Because full-frame installations are more involved, they will raise overall costs. A pocket installation entails installing a new window within the existing frame. So, instead of tearing out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which window installation service you should get, your installer should be able to assist you. In general, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Reston
In our hunt to make your home improvements easier and more eco-friendly in Reston, the EcoWatch Reviews team examined dozens of companies before settling on these. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Reston, we paid more attention to companies that cover the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Reston.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a substantial investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Reston's climate, homeowners need to be wary of low efficiency, water damage and rot. 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.
Reston, VA Window Replacement FAQs
What is the typical cost to replace windows?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally 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.
What kind of window is the most energy-efficient?
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're getting 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 do window installation companies do?
Window installation professionals will do the entire process — from replacing your old windows with new ones to cleaning up afterward. Additionally, a lot of companies offer window manufacturing, customization and repairs.
Should I replace all my windows at once?
If your windows are more than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
