We are a different kind of general contractor
After working in the construction business for years, Eric Raff and Dave Beck joined forces in 1992 and founded XL Construction. They chose the name "XL Construction" because they wanted their employees, subcontractors, and clients to know that their company's foremost mission was to EXCEL in each project they executed and to commit themselves to complete customer satisfaction. Within a few short years, XL Construction tackled some of the industry's most challenging and interesting projects, and their client list continued to grow. To support this growth, Mario Wijtman, a long-time leader in the biopharmaceutical sector, joined Eric and Dave as a partner in 1998.
While developing into one of the top general contractors in the Bay Area, we have retained our commitment to complete customer satisfaction, and live by our company values:
We value excellence, safety, integrity, innovation, passion and people
We support each of our projects with a team of experts and principal partners, ensuring we meet and even exceed our clients' expectations. In helping our clients achieve their goals, we have earned an extraordinary level of repeat business.
