Whole-House Repiping in San Jose, CA
If your San Jose home was built before the 1970s and still has its original galvanized steel pipes, they are rusting from the inside out right now. The symptoms creep up: pressure fades year by year, water runs brown after vacations, and pinhole leaks start appearing — first one, then a pattern.
Repiping replaces the supply system entirely with Type L copper or PEX. It sounds disruptive; done well, it is not. We work room by room, keep water on overnight, protect floors and furniture, and coordinate drywall patching so the house comes back together properly.
A repipe is also the moment to fix everything at once: new shut-off valves at every fixture, a proper pressure regulator, and clean hose bibs. Most single-family repipes take 2–4 days of pipe work. We quote the whole scope — pipe, patches, permits — in one written number.
Signs you need whole-house repiping help
- Low water pressure that has worsened over years
- Brown or yellow water after the house sits unused
- Repeated pinhole leaks in different spots
- Galvanized pipe visible at the water heater or under sinks
- Insurance carrier asking about plumbing age
Frequently asked questions
Copper or PEX — which should I choose?
Both are excellent. Copper is time-proven and rodent-proof; PEX is freeze-tolerant, quieter, cheaper, and faster to install. In practice we often recommend PEX for whole-house repipes and copper for exposed runs. We will price both for your home.
Will I have water during the repipe?
Yes — we run the new system alongside the old one and switch over near the end, so you are without water only for short, scheduled windows, never overnight.
Does a repipe require permits in San Jose?
Yes, a plumbing permit and inspection. We pull the permit, schedule the inspection, and meet the inspector — it is included in the quote, and you should be wary of any bid that skips it.
