I spoke with one of their team members, Earl, over the phone for about half an hour about a noise problem in my apartment. Earl was very knowledgeable, honest, and patient, and he answered all my questions clearly. He gave me practical advice on how insulation could help reduce the sound issues in my walls. Before finding this company, I had reached out to three other insulation contractors who said they couldn’t help with my situation. Earl, on the other hand, explained how their approach is different and how they could sol... read more

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
