About Pagac & Co
East Bay’s Trusted General Contractor Since 2009
David Pagac founded this company on a simple principle: do the work right the first time, be honest about what it costs, and treat every client’s home or building as if it were your own. More than 15 years and 200+ completed projects later, that principle still drives every decision we make.
We’re a licensed Class B General Contractor (CA Lic #812248) based in Concord, serving homeowners, property managers, and commercial clients across Contra Costa County. We self-perform our core work — no subcontractor relay, no communication breakdowns.
From a kitchen remodel in Walnut Creek to ADU construction in Lafayette, unit turnovers for a 40-unit complex in Martinez, or a commercial TI in Pleasant Hill — same crew, same standards, same accountability on every job.
