How Installing Energy-Efficient Windows in Leesburg Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Leesburg, that’s about 376 pounds per year on average.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Leesburg
Windows come in different styles, purposes and shapes, so costs and services will vary remarkably based on your project. Below, we describe the typical cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
According to our research, the typical 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, like number of windows, size, material, the location of your home, type and more.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Leesburg homeowners $353+ per year after replacing single-pane windows.
Asking for free quotes from multiple companies is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window within the old frame. So, instead of taking out the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company will be able to help you decide what’s best for your needs. In Leesburg, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Leesburg
The EcoWatch Reviews team differs from other reviewers since we evaluate these companies through a sustainability lens. We’ve decided to evaluate the top window installation companies in Leesburg mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, cost, quality of installation, quality of parts, warranty and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a substantial investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, 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.
Leesburg, VA Window Replacement FAQs
What is the average cost to replace windows?
The average cost of replacing a window ranges between $450 and $650. There are several factors that influence the cost, including your property’s location, the materials used in designing the windows, local labor costs, styles and sizes of windows, how energy-efficient the windows are and the number of windows.
What are the most common types of replacement windows?
There are several different types of windows you can get for your house, including awning windows, transom windows, picture windows, slider windows, casement windows, bay windows and double-hung and single-hung windows.
Do you really have to use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional. The window installation process is complex and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
How often should you replace your windows?
Windows typically last 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have them checked by an expert to determine if they need any repairs or replacements.
How long does it generally take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed during an 8-hour work day.
