I had mold on my garage ceiling from a roof leak. Called Zona because of its high Yelp rating. I was really impressed with the quality of people Zona sent out. They were all friendly and competent.
Zona removed part of the sheet rock and washed down any areas that might have mold. Nonetheless, their air test showed there was still mold around. So, they cleaned it again, and the garage passed the air test.
Zona has a construction division to restore areas they dismantle. I had them rebuild the ceiling portion that had been removed. The rebuilt ceiling looks like new.
These are really good people to deal with.
