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!

John O

Outstanding customer service and great job in the attic. The job was performed as required and professional manner.

Alfred B

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! 👍
