Richard R. says, "From estimate to final walkthrough, OT Bay Builders was outstanding. We thought we just needed cosmetic updates, but Aviad Cohen found major plumbing and electrical issues during the first walkthrough and explained everything honestly, with photos. He didn't try to scare us, he just laid out the options clearly. Breanna Magar handled scheduling for 3 months and kept all the different trades lined up perfectly - no waiting, no downtime. The tile work in the bathrooms is flawless, the cabinet work in the kitchen is perfect, and the finishing around every door and window is so clean. Great communication, very fair for this scope, and amazing workmanship. Yotum Vezumuski even stopped by on the last day to walk the house himself. That tells you everything about this company."See more

Reviews for San Francisco attic insulators on Thumbtack

From Thumbtack Customer

Quick and fair service to install insulation in my attic and crawlspace. They also rodent proofed the crawlspace.

From Ben R.

Eilon and his crew were quick to provide attic insulation services and were very considerate of the space - cleaned up when they were finished and completed the job quickly.

From Scott A.

Johnson’s Insulation

Johnson’s Insulation

Johnson’s did incredible work. In less than a week, we went from zero insulation in a messy attic to R38 installed at a much lower price than we expected and on-quote. The owner came by the next day to verify everything was done properly, too. We’d recommend Johnson’s to anyone.

From Sean D.

In the end work quality is good for the value, but unless you are there to inspect the work quality and don’t mind being rushed based upon when they complete their work, don’t expect communication and payment to be easy. This company did not have the boss supervising the quality of the finished product at the end and they really push to pay you on the same day regardless if you inspected or not. The insulation was laid professionally. Air seal with foam the boss had to come back and do. However they were extra helpful with getting me someone to help install my attic ladder and pick up the material from Home Depot. I would have given five stars if it would have been easier dealing with the boss. I included the photos of before because the guys did great work just needed direction and understanding
