Why you can trust EcoWatch
Whether you're updating for aesthetics or have windows that need repairs, windows play a vital role in conserving energy in your home. If your windows are outdated or drafty, you could be losing 25-30% of your home's heat or cool air right out of them.
That's also bad for the environment, as the extra energy used by damaged windows increases your carbon footprint.
Unlike other review sites, EcoWatch ranks window installation companies based on energy efficiency while also factoring in cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Sterling Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Better temperature control in your home: Residing in a hot place like Sterling can often mean relying on your AC to keep your home cool. Energy-efficient windows can cut back on how hard your AC needs to work to cool your home.
- Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $353 annually on your energy bills in Sterling.
Estimated Cost of Window Replacement in Sterling
Windows come in various purposes, shapes and styles, so costs and services will differ considerably depending on several factors. Below, we detail the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, including the location of your home, number of windows, material, size, type and more.
It's important to note 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 certified energy-efficient windows can save Sterling homeowners $353+ a year when replacing single-pane windows.
We advise getting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
The first step of a window replacement is to think about whether you want a full-frame or pocket installation.
A full-frame installation is a replacement of the total window. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without replacing the frame. So, instead of taking out the whole window and rebuilding it, the installer will just slide 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 Sterling, the decision will mostly be based on the age of your home and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Sterling
EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Sterling and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Sterling, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Sterling.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine 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 indicates the quality of services across most other categories, including quality of installation, professionalism, warranty, cost, quality of parts and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure 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. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Sterling's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Sterling window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Sterling, VA Window Replacement FAQs
How much should a window install cost?
The typical cost of installing a single window can range between $450 and $650. There are many factors that affect how much it costs, such as your property's location, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, the number of windows and local labor costs.
Which kind of window is the best?
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'll have the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Do you really need to use a window installation company?
Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
How long does window installation take?
Since a window takes about 30 minutes to install, around 16 windows can be installed during a typical 8-hour work day.
Should I replace my windows all at once?
If you're upgrading your windows to get more efficient windows, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
