Why you can trust EcoWatch
A guide on the top window replacement companies in Ashburn may not seem like the most riveting article on the EcoWatch site, but trust us, windows have more of an impact on your life than you might realize. Outdated windows can cost you in electricity bills. In fact, the Department of Energy estimates that 25-30% of your house's heat or cool air could be lost through your windows.
That's also bad news for the environment because the additional energy required by outdated windows increases your carbon footprint.
So if you're building a new home, renovating or updating your windows in Ashburn, you've found the best place to get started.

How Installing Energy-Efficient Windows in Ashburn Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on power bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Ashburn
Windows come in different purposes, shapes and styles, so costs and services will vary remarkably based on your project. Below, we describe the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
Typically, Ashburn homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at around $600. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that upgrading the windows on your Ashburn home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're unsure which type of window installation service you should get, your installer can advise you. Generally, the choice 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 Ashburn
EcoWatch reviews are different from other reviews because we examine these companies through a sustainability lens. We have decided to evaluate the best window installers in Ashburn mostly based on their energy efficient offerings, 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 takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company included in our guide to make sure its contractors are well-qualified and that the company has gotten lots 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 positive things to say about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
