All Seasons Construction has been serving Alameda and West Contra Costa Counties since 1993. Focusing on foundation and drainage work, it specializes in foundation replacement and perimeter drainage/waterproofing, and also provides retaining walls, earthquake retrofitting and decks.

Owner Mark Corrallo says proper retaining walls, concrete application and drainage systems are critical to keeping homes protected from rainfall, ground water and runoff. Mr. Corrallo started All Seasons Construction when he noted an overall lack of professionalism in the industry and, he says, felt he needed to address this issue.

All Seasons Construction’s experienced foremen supervise every job to ensure all work will stand the test of time. Likewise, says Mr. Corrallo, they strive to build trust and lasting relationships with customers. The company’s workers are insured employees, not day laborers. Even the most junior laborer has been on the company payroll for at least two years.
