Whole-House Repiping in San Jose, CA

CSLB #723684 · 24/7 emergency service

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 and 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 to 4 days of pipe work. We quote the whole scope, including pipe, patches and permits, in one written number.

Questions we get asked

Copper or PEX: which should I choose?+

Both are good, and the right answer depends on the house more than on the material. Copper is rigid, it has decades of track record, and it looks like proper work when it is exposed in a garage or a crawlspace. PEX is flexible, which means fewer joints and far less opening of walls to route it, so on a finished house with awkward runs it often means noticeably less drywall repair. PEX also tolerates our water chemistry well and does not develop pinholes the way copper eventually does. Where we lean copper is on exposed runs and where it connects to existing copper; where we lean PEX is long concealed runs through finished space. We will walk the house and tell you which parts suit which.

Will I have water during the repipe?+

During working hours the water is off while we are cutting and connecting, and we turn it back on at the end of each day so the house is usable overnight. That is the normal rhythm: no water during the day, water in the evening. We work room by room rather than opening the whole house at once, so on a multi-day job there are usually fixtures still in service even while we are working. If there is a particular bathroom or the kitchen you need kept running for a specific reason, tell us before we start and we will sequence the work around it. What we will not do is leave you without water overnight without warning you well in advance.

Who handles the permit and inspection on a repipe?+

We do. On a job this size the paperwork and the inspection are part of what you are hiring us for, not something we hand back to you to chase, and the cost of handling it sits in the quote rather than appearing later. It is worth being wary of anyone offering a whole-house repipe noticeably cheaper by leaving that side of it out. It tends to surface at the worst possible moment: when you sell the house and a buyer asks what was done, or when an insurer wants to know who signed off on work that later failed. Documented work is worth a good deal more than the small saving of undocumented work.
