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! ?
