How Installing Energy-Efficient Windows in Gillespie Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
- Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on energy bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save about $319 annually on your energy bills in Gillespie.
Estimated Cost of Window Replacement in Gillespie
Windows come in various shapes and sizes, so costs and services will differ considerably. Here are the average costs and services that you'll find from window installers.
How Much Do New Windows Cost?
On average, Gillespie homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. But costs will vary significantly depending on the quality of your products, the number of windows you need, your location and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Getting free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first step when considering an installation is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
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 Gillespie
EcoWatch is different from other reviewers since we're examining these companies through a sustainability lens. We've evaluated the top window replacement companies in Gillespie mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your 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 best window installation company near you.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you get. 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 determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, warranty, professionalism, quality of installation, quality of parts 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
Protecting your investment in new windows is important. For that reason, window installation companies that give you 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 good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
