Taylor Morales2024-01-05 i called to get a quote to top off my attic insulation they call this putting lipstick on a pig! lol had them come out for a diagnostic and they uncovered the real deal about what was going on. i hired them and it took several weeks to get on the schedule to do the work they did a really good job. very happy Albian Barban2024-01-05 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 Rice2024-01-05 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 Spring2024-01-05 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 Studios2024-01-05 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 Noble2024-01-05 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 Iannalo2023-10-15 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 Dinwiddie2023-09-22 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 Ballard2023-09-18 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.
