All Seasons Construction is a general contracting firm that specializes in foundation and drainage work for residential clients in Oakland, Berkeley, and the neighboring communities. In addition to foundation replacement and perimeter drainage/waterproofing, the company handles earthquake retrofitting, retaining walls and concrete work.

President Mark Corrallo, a former trial attorney and businessman, says proper retaining walls, concrete application and drainage systems are critical for keeping homes protected from rainfall, groundwater and runoff. Mr. Corrallo started All Seasons Construction when he noted an overall lack of professionalism in the industry and “decided to do something about it.”

All Seasons Construction’s experienced foremen supervise every job and ensure all work will stand the test of time. Likewise, says Mr. Corrallo, they work hard to build trust and lasting relationships with customers. The company’s workers are all insured employees, not day laborers, and all its foremen have been with the company for more than 15 years.
