Commercial plumbing for buildings that can't spring a leak.
Domestic water, sanitary and storm drainage, medical gas, backflow and water heating — Gerasa delivers the full plumbing scope for commercial projects across Ashburn, Northern Virginia and the Greater D.C. metro, built to code and built to last.
Pressure, drainage and code — handled.
Commercial plumbing carries risk most trades don't: a buried defect can flood a finished floor or fail an inspection weeks before opening. Gerasa engineers the plumbing scope in BIM, coordinates it with the structure and other trades, and builds it to pass the first time.
We deliver new construction, fit-out and retrofit plumbing as a design-build partner, in design-assist, or to an engineer's plan-and-spec drawings — one accountable partner from rough-in to final fixtures.
Why it matters for your bid
Coordinated, code-compliant plumbing keeps inspections clean and the schedule intact. We identify conflicts and long-lead fixtures early and prefabricate risers and assemblies where it tightens the program.
