How Installing Energy-Efficient Windows in Manassas Park Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- More efficient energy use in your home: In Manassas Park where the summers can be quite hot, energy-efficient windows reduce the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.
- More efficient energy usage in your household: In Manassas Park where the winters can be very cold, energy-efficient windows decrease the amount of heat that is lost through your windows, which makes it easier to keep your home warm.
- Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Manassas Park
When considering window installation, each company provides different services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
According to our research, the typical cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. This is because the cost of window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Manassas Park homeowners $359+ a year when replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the full window, including the frame, trim and sill. A pocket installation means replacing a window without removing the complete frame, which tends to be less expensive than a full-frame installation.
If you're not sure which kind of window installation service you should get, your installer can help you out. Generally, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Manassas Park
EcoWatch differs from other reviewers since we assess these companies through a sustainability lens. We've assessed the top window installation companies in Manassas Park mainly based on energy efficiency, 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 considers the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Manassas Park 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 installer included in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of installation, professionalism, quality of parts, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher scores 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Manassas Park, VA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a window is around $600 but can range between $200 and $1,200, depending on several factors. The price is usually influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want 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.
Do you really need to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring the pros. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.
How often do you need to replace your windows?
Windows usually have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
