Why you can trust EcoWatch
Whether you're doing home renovations or have old windows, windows play a crucial role in conserving electricity in your home. Outdated windows can cost you in electricity bills. In fact, the Department of Energy estimates that about 30% of your home's heat or cool air could be lost through your windows.
Installing efficient windows on your property can help you save money every month on your electric bills — and you can help the environment, too.
Unlike other sites, EcoWatch ranks window installation companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Herndon Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- 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.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 376 pounds per year on average.
Estimated Cost of Window Replacement in Herndon
Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. This is due to the fact that the cost of window installations are based on several factors specific to your home, such as 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 typically cost more upfront, but Energy Star predicts that upgrading the windows on your Herndon home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material of the frame you choose. Aluminum frames are typically the least expensive and are sturdy and light, but they provide 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 as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies offer: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation means replacing a window without removing the whole frame, which is generally cheaper than a full-frame installation.
Your window replacement company will be able to help you understand what's best for your needs. In Herndon, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Herndon
In our hunt to make your home improvements easier and more eco-friendly in Herndon, the EcoWatch Reviews team examined many companies before deciding on these. We have decided to evaluate the best window replacement companies in Herndon mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Herndon, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Herndon.
Work Quality
When selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded 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 installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Herndon, VA Window Replacement FAQs
How much should a window install cost?
The typical cost of replacing one window can range between $450 and $650. There are many factors that influence the cost, which include styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows, the number of windows, your property's location and local labor costs.
Which kind of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are 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 attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, it shouldn't be raining, because rain can make the installation harder.
How often do you need to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
