A UNIQUE STORY
CAWC Waterproofing & Restoration has been a family-run business for three generations beginning in 1968. Over time, CAWC has become one of Northern California's leading waterproofing and restoration contracting firms.
Since the beginning, our approach has been to personally supervise each project to ensure quality and service meet or exceed client expectations. Today, the company is run by Roy Mayer with his wife Sharon and their family. Each family member is a highly skilled professional, which makes them uniquely dedicated to the company's reputation for quality and craftsmanship.
CAWC is committed to the highest standards, reflected in cost-effective analysis, product durability, providing the latest technology, and a well-trained crew of dependable workers.

RENEGADE
Head of Security / Official Greeter
His bark had no equal — Rennie could have run the entire show on his own since he joined CAWC as a pee-on (literally). But after he became The BIG Dog, he preferred greeting the mail carrier and checking out the lunch room. We will miss him.
