How Installing Energy-Efficient Windows in Lorton Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- More efficient energy use in your home: In Lorton where the summers can be quite hot, energy-efficient windows decrease how much cool air is lost through your windows, which makes it easier to keep your home cool.
- Better temperature control in your home: Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
- Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Lorton
Let's go over the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Although the typical of replacing a single window is around $600, it can range anywhere from $200 to $1,200. But costs will differ significantly depending on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lorton homeowners $359+ a year after replacing single-pane windows.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. So, instead of removing the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Lorton
The EcoWatch Reviews team differs from most reviewers because we look at these companies through a sustainability lens. We have evaluated the best window installers in Lorton primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Lorton, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Lorton.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, cost, warranty, professionalism, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
