Every project operates under licensed general contractor oversight, combining structural framing with waterproof substrate engineering built to outlast wet urban conditions.
Curbless Showers and Tile
Architectural Kitchen Rebuilds
Plumbing Stack Modernization
Linear trench drain installation, bonded uncoupling waterproofing, and calibrated large-format stone setting tailored to historic settling and subfloor deflection.
Load-bearing partition removals engineered with structural steel posts, continuous exhaust venting, integrated task illumination, and bespoke hardwood casework.
Cast-iron waste stack replacement, acoustic pipe insulation inside shared condo demising walls, and high-pressure manifold loops dialed for multi-story pressure balance.
Methodical Jobsite Execution
Permits and Engineering
Negative-Air Dust Containment
Rough-In and Waterproofing
Tile Setting and Finish Out
We submit architectural drawings, coordinate structural engineering calculations, and pull all San Francisco DBI building, plumbing, and electrical permits before demo.
Plumbing valves, electrical homeruns, and sheet-applied waterproof membranes undergo continuous hydrostatic flood testing prior to city rough inspection sign-off.
Mitered stone margins, plumb cabinet reveals, and calibrated fixture trim are installed under razor-sharp quality controls before final inspection and handover.
Heavy-mil poly enclosures, HEPA air scrubbers, and neoprene floor armor seal your living quarters and common corridors against microscopic drywall and mortar dust.
Immediate Intervention for Active Plumbing Failures
Active supply line breaches and failed waste stacks threaten building structures within hours. Our Hayes Valley team deploys diagnostic scopes, containment tooling, and licensed pipe remediation throughout the city.
