  Our home is 33 years old and needed insulation installed based on age and not maintaining cool air from escaping and heat coming in. After research and meeting with Peter for an assessment we selected Kasi based on pros and cons. The team arrived and educated us the whole way. We were impressed with everyone especially Abel and Dustin. They identified unexpected issues and did a great job with recommendations and solutions. We love the temperature gauge which allows us to monitor and compare attic and the in home temperatures. Thank you Kasi!! Browns of Phoenix

  The experience with foam insulation of my garage was exceptional, and the results are unbelievable. The entire team—sales, owner, and installers—was easy to work with, professional, and applied zero pressure. The thermal performance is night and day. Even when it's scorching hot outside, the interior temperature is drastically reduced and remains manageable. My mini-split rarely runs, and when it does, it cools by 10∘F in just one hour! This efficiency is a massive improvement. A huge thank you to Dustin, the installer, who went above and beyond. He added extra insulation in corners and patched everything so cleanly that I won't need to repaint. In fact, the results were so impressive that I showed two neighbors, and they both instantly decided to foam insulate their own garages. Highest recommendation!

  Kasi foamed my walls and attic in my new build, I couldn't be happier with the quality of work and professionalism. This is the first house I have lived in with foam as my insulation and does makes a huge difference with comfort and costs. Highly recommend.

  We used Kasi foam insulation on an interior room and garage roof. The installation team of Joe and Dustin did an outstanding job. On time, clean and delivered a thorough job.

  They came to our home on time. They did an excellent job. We had some siding installed by a "handy man" a couple a years ago. Retrofoam noticed that they had not adequately screwed down about half of the siding that was installed. They fixed it for us at no additional charge. The man that came was very courteous and finished the job within the time he said he would. Our home is cooler in summer, and warmer in winter. Plus, it is quietier as well. We are very happy with the work they did and would highly recommend them to anyone who wants to make their home more energy efficient.
