How Installing Energy-Efficient Windows in Potomac Mills Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Potomac Mills
Let's take a look at the cost of replacing your windows and the types of services offered by installers.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost depends on several factors, including number of windows, type, material, the location of your home, size and more.
It's also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Potomac Mills home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise requesting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Potomac Mills
In our search to make your home improvements easier and more eco-friendly in Potomac Mills, the EcoWatch team landed on the above companies as the best window installation companies in the city. We have decided to assess the best window replacement companies in Potomac Mills mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Potomac Mills, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Potomac Mills.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included in our guide to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction. 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, quality of parts, professionalism, cost, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies 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
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Potomac Mills' climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Potomac Mills window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Potomac Mills, VA Window Replacement FAQs
What is the typical cost to install windows?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the location of your property, the size of the window and the type and material 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.
What are the most common kinds of replacement windows?
There are several different kinds of windows you can get for your home, such as casement windows, awning windows, transom windows, slider windows, bay windows, double-hung and single-hung windows and picture windows.
What do window installers do?
Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up afterward. Additionally, a lot of companies offer window manufacturing, customization and repairs.
How long does window installation generally take?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
How do you know it's time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
