CAWC Waterproofing & Restoration has been one of Northern California’s leading waterproofing and restoration contracting firms since being founded in 1971 by Ted Mayer Sr. To ensure both quality and durability, our San Mateo-based company uses only the latest products and technology on every project. Customer satisfaction is our top priority.

With decades of experience, Ted and Roy Mayer, co-owners of CAWC, can address any of your immediate and long range concerns. Since the beginning, our approach has been to personally supervise the projects to ensure that quality and service meets or exceeds client expectations. Our foreman and supervisors have been employed by CAWC for an average of 15 years and have completed four years of waterproofing apprenticeship training through the local union state certified school. Our experience, technical expertise, and high-quality service provide our customers with the highest possible return on their maintenance investment.
