How Installing Energy-Efficient Windows in Fairfax Saves You Money

- Reduce your carbon footprint: In Fairfax, you can lower your indirect greenhouse gas emissions by about 324 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Fairfax
Let’s take a look at the cost of updating your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Even though the average cost to install one window is around $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, like size, the location of your home, type, number of windows, material and more.
It’s important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Fairfax homeowners $359+ a year when replacing single-pane windows.
We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In regard to window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. Because these installations are more involved, they will raise the total cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re unsure which kind of window installation service you need, your installer can advise you. Generally, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Fairfax
In our search to find the most reliable, eco-friendly window installers in Fairfax, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Fairfax and ranked them using the following methodology:
Service Area
Since this is a guide for Fairfax, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Fairfax.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in insulation 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, warranty, quality of parts, cost, professionalism and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a hefty investment, so you’ll want to be certain 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
Lastly, 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, VA Window Replacement FAQs
How much should a window install cost?
The national average cost of installing one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is typically dependent on the location of your property, the type and material of the window and the size of the window. Also, bear in mind 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 best for energy efficiency?
A window’s energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can I replace my own windows?
If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or experience, we recommend getting a professional to do it for you.
How often do you need to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
How long does it generally take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
