"Home Genius came by and installed my insulation into my attic and I couldn’t be more thrilled and happy with the results! I noticed an initial change with the first temperature drop of the winter! And I wasn’t cold one bit! Angel And Michael were both professional and knowledgeable and were available for any questions or concerns that I had! Thank you to Home Genius for my new roof and my new insulated attic! I would love to recommend them to all family and friends!"

"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"The team was excellent. Professional, timely, and courteous. Jessie the sales rep was very reliable and straight forward. He answers calls texts promptly. Did not push for extra sale, as a matter of fact they fixed things for me in the attic (switch box and AC ducts) without any extra charge. Mark the installer was very knowledgeable and did a thoroughly job. I would definitely recommend this company and team. I have dealt with many many contractors in California and these two were the best."
