Local Plumbing Repiping in San Francisco, CA
Repiping is local work in San Francisco: the conditions here decide which parts hold up. Set in California's Mediterranean climate region — a mild Mediterranean climate of warm, dry summers and gentle, damp winters, with low annual rainfall and abundant sun — homes here contend with hard, mineral-heavy water that scales pipes and water heaters and long dry spells that shift soil and crack buried pipe, so we spec corrosion- and climate-rated pipe, fittings, and fixtures rather than whatever's cheapest on the shelf. The failures we see most around San Francisco County are scale-clogged pipes and fixtures from hard water and slab leaks in aging copper under the foundation, and our repiping trucks are stocked for them. With 78% of local homes built before 1980, original galvanized pipe and aging fixtures past their service life are common — we size every fix to the system in front of us.
Local conditions put San Francisco squarely in California's Mediterranean climate region: a mild Mediterranean climate of warm, dry summers and gentle, damp winters, with low annual rainfall and abundant sun. On a home's plumbing that translates to hard, mineral-heavy water that scales pipes and water heaters, long dry spells that shift soil and crack buried pipe, and intense afternoon UV that degrades exposed PVC and hose bibs — which is why we spec corrosion- and freeze-rated pipe, fittings, and equipment for the local climate.
San Francisco's most common plumbing failures are scale-clogged pipes and fixtures from hard water, slab leaks in aging copper under the foundation, and failing water heaters past their 10–12 year life. None of it is coincidence — 40 days above 90°F push water heaters and expansion tanks to their limit, salt-laden coastal air corrodes copper, brass fittings, and water heater tanks, and 78% of local homes predate 1980 (median build year 1945), so many still run original galvanized steel or polybutylene pipe and fixtures well past their service life. We stock every San Francisco truck for precisely this corrosion and wear, and fix it in a single visit.
A whole-home repipe is the permanent fix for a house whose supply pipes have reached end-of-life — original galvanized steel closing up and rusting the water, polybutylene from the 1980s–90s failing without warning at the fittings, or copper that keeps developing pinhole leaks on run after run. Instead of chasing one leak at a time inside the walls, a repipe replaces the entire supply distribution in one planned project, restores full pressure to every fixture, and resets the clock on the most failure-prone system in the house.
We repipe in PEX-A and type-L copper. PEX-A is flexible, freeze-tolerant, corrosion-proof, and fast to route with fewer fittings inside the walls, which means fewer potential leak points and a lower cost; type-L copper is rigid, time-proven, and preferred where exposed runs, high heat, or local code call for it. Our plumbers map the runs, open the minimum number of access points, pull the new lines, tie in every fixture, and pressure-test the whole system before anything is closed.
Repiping is turn-key: free on-site consultation, a written quote good for 30 days, permits pulled and the municipal inspection scheduled, drywall access points patched and textured, and the water restored the same day in most single-story homes. Financing is available through Synchrony at 0% APR for the first 12 months on projects over $1,500, and the work carries a 10-year workmanship guarantee on top of the pipe manufacturer's warranty.

Signs you need repiping
Locally in San Francisco, it usually surfaces as slab leaks in aging copper under the foundation.
Home built before 1975
Homes from before the mid-1970s often still run original galvanized steel well past its 50-year life. If it's never been repiped, the pipe is living on borrowed time.
Weak pressure throughout the house
When every fixture runs weak, not just one, the supply pipe has narrowed from the inside across the whole home. New full-bore pipe restores the pressure the fixtures were designed for.
Polybutylene pipe anywhere in the home
Gray polybutylene supply pipe becomes brittle and fails at the fittings unpredictably. Insurers often won't cover it, and a proactive repipe removes the liability before it lets go.
Repeated pinhole leaks
A copper system that leaks a pinhole, gets patched, then leaks another one on a different run within months has aggressive water eating it everywhere. Patching becomes a losing game — a repipe ends it.
Rusty or discolored water
Brown water at the first draw, or a metallic taste, means galvanized pipe is corroding from the inside. When it's happening at multiple fixtures, the whole distribution is due.
Why it happens & what we fix
Galvanized steel at end-of-life
Galvanized pipe corrodes and closes from the inside over decades until flow drops and the water rusts. There's no reversing it — the material has simply reached the end of its service life.
Hard-water and coastal corrosion
Mineral scale narrows pipe from the inside while coastal salt air corrodes it from the outside, and both accelerate a supply system toward whole-home failure.
Aggressive-water copper pitting
Acidic or high-velocity water pits copper from the inside until pinholes weep through, clustering on hot and recirculation lines. When it recurs across runs, the system is the problem.
Polybutylene brittleness
Poly pipe and its acetal fittings degrade with exposure to chlorinated water and become brittle, failing at the joints without warning. Whole-home replacement is the only reliable fix.
Undersized original distribution
Homes plumbed with undersized trunk lines never delivered proper pressure to simultaneous fixtures. A repipe is the chance to correct the sizing, not just replace the pipe.
Weather wear, San Francisco edition
Being in California's Mediterranean climate region means hard, mineral-heavy water that scales pipes and water heaters; in San Francisco the result we see most is scale-clogged pipes and fixtures from hard water, and the trucks are stocked for it.
