Calculate how much you can expect to pay for window installation and replacement in Mount Vernon, 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 Mount Vernon Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save $359 a year on your bills.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Mount Vernon
Each window installer provides various services and has varying price points depending on several factors.
How Much Do New Windows Cost?
On average, Mount Vernon homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at about $600. These estimates vary depending on the specifics of your installation, like the location of your home, size, number of windows, material, type and more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Mount Vernon homeowners $359+ a year after replacing single-pane windows.
Something else that influences the overall cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a window installation is to figure out whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations are on the simpler end and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Mount Vernon
The EcoWatch Reviews team is different from other reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:
Service Area
Because this is a guide for Mount Vernon, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Mount Vernon.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most 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 spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Mount Vernon’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Mount Vernon window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
