Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. Traditional, outdated windows can cost you in electric bills. As a matter of fact, the Department of Energy estimates that 25-30% of your home's heat or cool air could be lost through your windows.
Installing efficient windows on your home can help you save money each month on your electric bills — and you can help the environment, too.
Efficient windows are particularly important in Mount Vernon, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $359 each year.

How Installing Energy-Efficient Windows in Mount Vernon Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Better temperature control in your home: Living in a hot city like Mount Vernon can often mean depending on your AC to keep your house cool. Energy-efficient windows can cut back on the amount of cool air lost through your windows when cooling your home.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Mount Vernon
Windows come in different purposes, styles and shapes, so costs and services will vary remarkably based on several factors. Below, we go over the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
According to our market research, the national average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, such as type, the location of your home, number of windows, material, size and more.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially 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+ each year after replacing single-pane windows.
Something else that affects the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two types that your installer will offer: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a 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 installation company can recommend the best type for your project. In Mount Vernon, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Mount Vernon
EcoWatch reviews differ from other reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:
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 a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to 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 trends in recent customer feedback to determine the companies with the most 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 nearly every category, including professionalism, quality of installation, cost, warranty, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. 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 Mount Vernon's climate, homeowners will want to mitigate low efficiency, rot and water damage. 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.
Mount Vernon, VA Window Replacement FAQs
What is the average cost to install new windows in a home?
The typical cost of installing a single window ranges from $450 to $650. There are several factors that affect how much it costs, such as how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, local labor costs, the number of windows and your property's location.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — this 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 handiness. Using a window installation company can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it usually take to install windows?
Each window takes about 30 minutes to install depending 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.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
