How Installing Energy-Efficient Windows in Manassas Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, such as:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Decrease your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Manassas
When researching window installation, each company provides different services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
Though the typical cost of replacing one window is about $600, it can range from $200 to $1,200. These figures vary depending on the specifics of your installation, such as number of windows, material, the location of your home, 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 by lowering your energy bills. Investing in Energy Star certified windows can save Manassas homeowners $359+ a year when replacing single-pane windows.
Requesting free quotes from multiple providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Manassas
EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. We’ve evaluated the best window installers in Manassas mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty 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
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured on this list to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, quality of installation, quality of parts, cost, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers may not provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Manassas’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Manassas window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Manassas, VA Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is typically influenced by the type and material of the window, the location of your property and the size 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.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be 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.
Can I install my own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it usually take to install windows?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
