CAWC crew

We get the job done!

CAWC has an outstanding and committed crew.


Our foreman and supervisors have been with us for an average of 15 years and completed 4 years of training through Local Union 220 (State-certified Roofers and Waterproofers Apprenticeship Program ).

Meet the Team


CAWC Waterproofing & Restoration has been a family-run business for three generations, beginning with Ted Mayer, Sr. who founded the company in 1968 with his wife Mary. In time, their two sons Ted, Jr. and Roy joined the business, and CAWC became 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 that quality and service meet or exceed client expectation. 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.







Roy was a high school freshman when the company was started by his father. Roy began working at CAWC as a laborer during summer vacations. After graduating from San Jose State with in 1980 with a BS Degree in Business he joined CAWC as an estimator, learning more of the trade, along with attending seminars and meetings with manufacturers. In the early 90’s, Roy began overseeing the daily operations and received his General Contractor's License. With over 40 years of experience, Roy takes pride in offering clients his experience, personal attention, and availability to solve their waterproofing problems — his knowledge and dedication are widely respected. 



Office Manager

Formerly employed at AT&T and at Bank of America (where she met Roy), Sharon became a key member at CAWC in 1992. Sharon oversees all of the accounting aspects of the business. Her administrative skills, background in finance, and her friendly approach with clients are key to running a smooth and efficient organization.



Executive Assistant

Gabi is a Jill of all trades. Not only did she catch Brennan's eye, the entire family recognized her professional merits when she joined CAWC in 2016. Her construction background and extensive IT and organizational skills have become indispensable in updating and streamlining office procedures. She also visits job sites with estimators to assist with job quotes. Gabi's efforts are key to keeping the operation current in today's environment.



Project Superintendent

Victor joined CAWC in 2006, and has since been an integral part of project operations. He coordinates with owners, directs the labor crew. and oversees scheduling. Above all, he ensures safety on the jobsite and quality control with all installations. In the field Victor is our "go-to" guy.



Project Manager

Brennan joined the team in 2010 after graduating from Cal Poly with a degree in Business. In managing the daily operations, he has become an expert in the field, along with receiving his painters contractors license. Brennan has gained a reputation for delivering excellent customer service with the competency to oversee the most complex project. And he has the expertise to complete each project on time and to the customer's satisfaction.



Project Estimator

Darren came on board in 2017 after graduating from San Francisco State University. He has the background, knowledge, and critical analytical skills to fully assess job specifications, identify product requirements, and factor labor costs to determine the most cost-effective solutions to meet our clients’ needs.



Head of Security / Greeting Committee

Last, but not least, is Rennie. His bark has no equal — and he could probably run the entire show on his own since he joined CAWC as a pee-on. But now that he's The BIG Dog, he would rather greet the mail carrier and check out the lunch room.
