How Installing Energy-Efficient Windows in Fairfax Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to think about making the switch:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 162 pounds.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save on energy bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in Fairfax
When considering window installation, each company offers different services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
Although the typical to install a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost depends on several factors, such as material, number of windows, size, the location of your home, type and more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Getting free quotes from multiple providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
When it comes to window replacements, there are generally two kinds that your installer will have: full-frame and pocket installations.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. 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 may need a full-frame installation instead.
If you're still trying to decide which kind of installation you need, you can talk to your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Fairfax
EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. We've reviewed the best window installers in Fairfax mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When selecting 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 get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, cost, quality of parts, professionalism, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) 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 experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Fairfax, VT Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on 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.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get 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 I really have to use a window installation company?
You should use a window installation company whenever you want new windows. Installing windows is a complex process that can be difficult to do on your own, so it's best left to the professionals.
How long does it generally take to install windows?
Since a window takes about 30 minutes to install, about 16 windows can be installed in an 8-hour work day.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all of your windows at once is the only way to gain that benefit. However, if you have only one or two windows that are broken or leaky, you can replace just those.
