I had a great experience with Alliance Room Addition & ADU Contractors when they worked on my small insulation project in Atherton. Before they arrived, I discussed my needs with them and we thought a denser spray foam would be best. But when Earl came out, his experience really showed—he explained that a less dense, better spreading foam would do a better job for what I wanted, which was both insulating and sealing up my house to keep mice out. Instead of just using whatever they had on hand, they actually packed up and cam... read more

I usually don’t write reviews, but I wanted to share my great experience with Alliance Room Addition & ADU Contractors. Landon and the crew did a fantastic job insulating our attic in Atherton. They installed a radiant barrier and added 10 inches of insulation, and we quickly noticed a big difference inside our home. Our AC now cools the house much faster and actually shuts off when it’s supposed to, instead of running all day. The indoor temperature stays comfortable, and the cool air lasts much longer. I’m sure the extra i... read more

not many reviews talk about the results of energy efficiency after insulation work, but i’ve been keeping an eye on it for months. since we had extra cellulose blown into our attic, there’s been a big drop in our electric bill. before the insulation, our 3000 sq ft house used an average amount of power, but now it’s one of the most efficient homes compared to others like it nearby. all thanks to jamie for doing a great job with the insulation!

The crew did a great job adding insulation to my attic. Earl and the team were professional and finished the work quickly. They made sure to clean up everything afterwards and treated my home with respect. I’m expecting my energy bills to go down because of the new insulation. In the office, Landon and Nolan handled all the rebate paperwork for me and answered my questions right away. They made the whole process easy. I highly recommend their insulation services.
