How Installing Energy-Efficient Windows in Gainesville Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Save on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Reduce your carbon footprint: In Gainesville, you can reduce your indirect greenhouse gas emissions by about 376 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Gainesville
Windows come in varying styles, purposes and shapes, so costs and services will differ tremendously based on several factors. Below, we detail the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Generally, Gainesville homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at about $600. These numbers are based on the specifics of your installation, like size, the location of your home, number of windows, material, type and more.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $360 a year on your energy bills in Gainesville.
We recommend requesting free quotes from several window installers to find the one that works best for you.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re still debating which kind of installation to get, you can ask your provider and get their advice. The choice mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Gainesville
In our hunt to find the most reliable, eco-friendly window installers in Gainesville, the EcoWatch team assessed dozens of companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Gainesville and assigned rankings using the following methodology:
Service Area
This one is 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 best window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you opt for. 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 customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, cost, warranty, quality of parts 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 the prices of providers, 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. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Gainesville, VA Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost of replacing a window ranges between $450 and $650. There are several factors that affect the cost, such as the number of windows, the materials used in designing the windows, your property’s location, styles and sizes of windows, how energy-efficient the windows are and local labor costs.
What are the most common kinds of replacement windows?
There are several different kinds of windows you can get for your home, including double-hung and single-hung windows, casement windows, awning windows, slider windows, picture windows, bay windows and transom windows.
What do window installation companies do?
Window installation professionals visit your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.
Should I replace my windows all at once?
If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
