“Excellent trustworthy company. Honest & upfront & QUALITY materials. We had all new LowE glass, double-paned windows installed.  Our energy bills have been cut in half! Recommend this professional company to all I come in contact with!”
– Kim

“Good quality windows at a fair price. The crew who installed the windows for the entire house did an excellent job. Left the job site clean, were fast, and it was a full crew, not just two guys. Fast service and the office staff is very helpful. Highly recommended! Just do it!”
– Tracy

“Great windows. The install crew Dave, Richard and Mike were top-notched. If I could give 10 stars I would. Their windows blocked the noise from road traffic next to my house.”
– Devin

“No longer is our A/C struggling to keep up with the 100+ degree August days and our energy-efficient windows are to thank. Lastly, we live in a dense and sometimes noisy neighborhood with a garage band that sometimes practices next door, so we added on the Sound Reduction package and it made a huge difference helping keep our house quieter.”

Expensive: The amount you save when you purchase standard windows, you lose on your energy bills, and when you sell your house.

Inefficient: Most houses come installed with aluminum-framed windows. As you may know, aluminum is an excellent thermal energy conductor making it a horrible material for energy efficiency.

x icon

Basic Design: Ordinary windows are just that: ordinary. No one is going to take notice of them, and they don’t add any curb appeal to your home.

x icon

Easily Breakable: Single-pane windows break incredibly easily. Thieves looking to break into your home through a window will have no problem.

Difficult to Maintain: With wooden windows, you have to sand, repair, and repaint them year after year. Even then, they don’t age well.

Don’t get stuck paying more over time for old-school windows.

Frequently Asked Questions

Why should I replace my windows?

You should consider replacing your windows if they are difficult to clean and operate, lead to mold development, have a poor appearance, are inefficient at conserving energy, or allow noise pollution or windy drafts to enter your home.

What type of windows should I choose for my home?

Today, over 70% of all replacement windows installed are vinyl. At Green Energy of San Antonio, all of our windows are made with vinyl. With full insulation, they keep your home cooler in the summer and warmer in the winter.

How much will it cost to replace my home’s windows?

Through our current promotion, customers can purchase 10 double hung windows for $8,990. With this promotion, labor is included and you can save over $2,500 from our original price of $11,500. If your home has more or less windows, contact Green Energy of San Antonio to receive a quote for your window replacement needs. We always aim to offer affordable windows for our replacement window services.

Is financing available for window replacement?

Yes, financing is available for our replacement window services. For more information, use our Financing Calculator at the top of this page or contact us to learn more.

What is the ROI for installing energy-efficient windows in my home?

According to Realtor.com, homeowners can expect to recover up to 70% of their investment in energy-efficient windows. Additionally, the U.S. Department of Energy estimates that homeowners can save "between $126 to $465 a year by replacing single-pane windows".

Where is my home’s energy lost?

The majority of your home's energy can be lost through its windows and doors. More specifically, 70% of heating and 46% of air conditioning is lost through these avenues. If you don't replace your windows or doors, your home's energy costs could continue to rise.

How often should my windows be replaced?

Most home windows have an average lifespan of anywhere from 15 to 20 years. Once windows reach this age, their seals tend to start to weaken or fail. Failing or weakened window seals can lead to water seepage from rain or snow, as well as drafts. Additionally, if your home still has standard single pane windows, you should consider replacing them as soon as possible regardless of age. The energy efficiency and insulation provided by standard single-pane windows simply do not compete with the benefits provided by double-paned windows.

Should I replace all my windows at once?

In most cases, the more replacement windows you install in one go, the cheaper the project will end up being. By replacing your windows all at once, they will also age at about the same rate, allowing you to save money the next time you require replacement as well. Green Energy has several financing options available so you can accomplish whole house window replacement without breaking the bank.

Can I replace my windows myself?

Green Energy of San Antonio does not recommend performing DIY window replacement. Not only can a small mistake mean drafts and water leaking into your home through the windows, but DIY window replacement is dangerous when working on the 2nd and 3rd floors. Our experts have performed window replacement in San Antonio countless times, and you can be sure that the job will be done correctly and safely.

What kind of windows are offered by Green Energy of San Antonio?

At Green Energy of San Antonio, we offer energy-efficient windows of several different styles. With Green Energy, you can choose from slider, casement, picture, double hung, and even custom specialty windows for our window replacement services.

Will windows from Green Energy of San Antonio reduce outside noise?

With our Serenity Sound Package, you can enjoy noise reduction of up to 33 decibels. Many homeowners don’t realize that their homes will be plagued with noise pollution until they’ve been moved in for a while. Windows from Green Energy of San Antonio can provide your home with considerably more peace and quiet.
