How Installing Energy-Efficient Windows in Falls Church 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:
- Save on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your home.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Falls Church
Each window installer offers varying services and has varying costs based on several factors.
How Much Do New Windows Cost?
On average, Falls Church homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at about $600. How much it will cost varies based on several factors, including size, number of windows, the location of your home, material, type and more.
It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Falls Church home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from several window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the total window, including the trim, frame and sill. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
Your window replacement company will be able to help you understand what’s best for your needs. In Falls Church, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if it’s not maintained properly 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 Falls Church
In our hunt to make your home improvements easier and more eco-friendly in Falls Church, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings based on 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 on this list to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, warranty, professionalism, quality of parts, quality of installation and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Falls Church’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Falls Church window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Falls Church, VA Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost of replacing one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the types of windows?
There are several different kinds of windows you can get for your house, such as casement windows, awning windows, slider windows, bay windows, transom windows, double-hung and single-hung windows and picture windows.
Can I replace my own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional 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.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
How long does window installation take?
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 have a lot of windows that need to be installed.
