I like working with the Stellrr team on my crawlspace conversión. It was dirty and moldy. Now it is súper clean and I can store my stuff down there. A plus. Christian Rice2024-01-05Trustindex verifies that the original source of the review is Google. I would recommend Stellrr to anyone. They insulated my attic at a fair price and I know I can trust them. Angel and his team replaced the old fiberglass insulation in my attic with cellulose, air-sealed my attic, and insulated my catwalk. They were on-time, communicative, and did great work. I was impressed every step of the way. They also went above and beyond, adding extra insulation at no charge! Mr. Wayne followed up weeks later for quality control and added more insulation and air sealing that was even more than what we had contracted for. I can't recommend Stellrr enough! This isn't a paid promotion or anything, I just think more people should contract with Stellrr and want to let people know that my experience with them was phenomenal. I recommend them 100%. Amber Spring2024-01-05Trustindex verifies that the original source of the review is Google. From my first phone call with Jeremy, to my consult with Sheldon… and the install crew, I could not be more pleased with how respectful everyone was. They vacuumed out all the old insulation. We don’t know the house had rat problems because it had been burried. But I’m so glad to have that out of the house. And now our air is so much cleaner. They spray foamed the roof for me and it is just like a cozy blanket. RJD Studios2024-01-05Trustindex verifies that the original source of the review is Google. I had my insulation replaced by stellar and I have to say it was a way better experience than I expected! The staff was very well mannered and gave me all the answers to every one of my questions. My electric bill is lower and my life is much easier. Highly reccomend! Kristina Noble2024-01-05Trustindex verifies that the original source of the review is Google. My house had this really uncomfortable room that we just couldn't keep under control. We hired stellar to come out and do the Space Age Cleanse. The process took a little longer than the minimum expected time. But we are very happy with the results. My bills are way down a d the room finally stays the same temperature as the rest of the house. Couldn't be better. Zelma Iannalo2023-10-15Trustindex verifies that the original source of the review is Google. The team at Stellrr Insulation did an exceptional job with our attic insulation. Sheldon was incredibly helpful in explaining the process and the crew led by Robert was efficient and professional. We're noticing the difference already - the temperature is more consistent throughout the house, and our HVAC is running much better. James Dinwiddie2023-09-22Trustindex verifies that the original source of the review is Google. Shawn and his team have truly changed our lives. Their professional and efficient work in removing our old insulation and installing new spray foam insulation has resulted in a more comfortable home and a more efficient HVAC system. We are very satisfied with their services. Jacob Ballard2023-09-18Trustindex verifies that the original source of the review is Google. I had an issue with Stellrr where they missed a portion of my attic when insulating, however when it was caught they went above and beyond to ensure it was fixed properly and I wasn’t charged for the fix I appreciated the professionalism of them and their motivation to take care of a client.

Answers You Need About Spray Foam in South Lamar
How long does spray foam insulation last in South Lamar homes?
Spray foam insulation can last over 30 years if installed correctly. South Lamar’s warm climate and building types make it a long-term solution for reducing energy costs.
Will spray foam reduce humidity inside my house?
Yes. Closed cell foam forms an air and moisture barrier, which helps control indoor humidity especially helpful in older homes near Zilker and Galindo.
Can I install spray foam in an existing home?
Absolutely. We specialize in retrofitting existing structures without major disruption. Many South Lamar homes see big improvements with attic or wall upgrades.
What’s the difference between open cell and closed cell foam?
Open cell is lighter, sound-absorbing, and better for interior spaces. Closed cell is denser, adds structural support, and blocks moisture. We help you choose based on your space.
How do I know if I need insulation removal first?
If your current insulation is moldy, rodent-damaged, or ineffective, removal is often the first step. We assess your attic or crawl space to recommend what’s next.
