I recently hired California Attic & Build for an attic insulation and clean-up project, and I couldn’t be happier with the results! From start to finish, their team was professional, punctual, and extremely knowledgeable. They walked me through the entire process, answered all my questions, and delivered high-quality work on time and within budget. The crew was respectful of my home, cleaned up thoroughly after the job, and made sure everything was up to code. I noticed a difference in my home’s temperature control almost immediately. If you’re looking for a reliable, honest, and skilled company, look no further than California Attic & Build. Highly

I called California Attic for my Insualtion project and they were stellar! Didn’t know what type of insualtion would be best for my home and their technician Sean was so good at explaining to me my options. I went ahead with the cellulose and I couldn’t be happier with the result! My home is so much more stable now and I feel like I’m never turning on the air. Couldn’t recommend this team more! Thank you Sean and the California Attic team
