Why Insulate Your Home?
How Can Insulation Improve a Home’s Comfort & Efficiency?
When the neighbors are loud, you can hear it. When the weather is cold, you can feel it. When the energy bill comes in, you dread it.
The good news is one home improvement could solve most of your problems: spray foam insulation. Spray foam insulation is versatile. It can be used to re-insulate older homes that contain little or no insulation. Best of all, the process is simple, taking one or two days, with very little disruption to your household.
Choosing foam insulation is a very effective way to prevent large amounts of heat loss, filling voids and cracks in the walls, attic, crawl space, rim joist, and basement, even filling irregular shapes and gaps.
Because foam insulation has sound deadening characteristics, you will enjoy a home that is quieter from outside noise. Because foam insulation creates a seal around your home, warm air won’t escape, and cold air won’t creep in. Because foam insulation ensures a more consistent temperature in your home, your energy bills will be much, much lower.

Our Homeowners Say
Adding Insulation has lowered my electric bill significantly! Thanks to the incredible, prompt, quick and reasonably priced job by South Texas Insulation. I would highly recommend them to anyone. We thought our AC unit was not getting the job done but it was lack of insulation!! Thanks again!
This has been the absolute best company to work with! From the estimate to actual job completion was fast and easy and very professional!! Ernie, the owner is an awesome guy and really cares about his clients! By far the best insulation company I’ve ever used!!!
Great work and a great price! Antonio explained the entire process and all the guys were great. I would highly recommend them.
It’s been a pleasure doing business with South Texas Insulation, when they say there going to do something it gets done on time and on budget.
Outstanding customer service and great job in the attic. The job was performed as required and professional manner.
Always go with STI! They are nothing but professionals. They get the job done right the first time. Ernie was the best! He stayed in contact with us making sure everything was going smoothly, and of course it was. We could have gone with a company closer to us that was about the same costs, but I read the reviews of STI and was sold they were the ones to go with. SO GLAD WE DID. Great job guys. It’s been a year and our shop is 20 degrees cooler than the outside temps and that’s saying something! ?
