Repiping in Newark & the East Bay

A lot of the homes we work in across the East Bay were built between the 1950s and the 1970s, and many still run on the original galvanized steel supply piping. Galvanized pipe corrodes from the inside out. The zinc coating wears away, rust and mineral scale build up on the interior walls, and the usable diameter of the pipe slowly closes in. You cannot see this from the outside, so the pipe can look fine while the inside is nearly choked off.

Our moderately hard ACWD water in the Tri-City area adds to it. Scale settles in the same spots where corrosion is already narrowing the line, which speeds up the loss of flow. By the time most homeowners call us, the pipe has been declining for years.

When pressure drops at one faucet, the problem is usually that fixture: a clogged aerator, a bad cartridge, or a stop valve that is partly closed. We always check the cheap, local causes first, because a repipe is a real project and you should not pay for one you do not need.

When pressure falls off across the whole house, when hot water runs weaker than cold (the hot lines scale faster), when you see rusty or discolored water on the first draw in the morning, or when you start getting pinhole leaks in more than one spot, that pattern points to the supply piping itself. One pinhole in old galvanized usually means more are coming, because the whole run is the same age and in the same condition.

We replace supply lines with either PEX or copper. PEX is flexible, which means fewer fittings and joints, and it can often be routed through existing wall and ceiling cavities with smaller access openings, so there is less to patch afterward. It also handles our hard water and any seasonal cold well. Copper is rigid and time-proven, and some homeowners simply prefer it. Both are good materials installed correctly. We will walk you through the trade-offs for your house rather than pushing one.

A partial or section repipe replaces only a defined run, for example one bad branch or the line feeding a single bathroom. It can be the right call when the failure is genuinely isolated and the rest of the system is sound. We are honest about the limit here: if the whole house is original galvanized of the same vintage, replacing one section often just moves the next pinhole leak down the line. In that case a whole-home repipe usually costs less over time than chasing repeated repairs through finished walls.

Most of the disruption in a repipe is not the pipe, it is the drywall. So before we cut anything, we map the existing routing and plan access points that follow the path of the old lines and use closets, the garage, the attic, or the crawlspace wherever we can reach them. The goal is the fewest, smallest openings that still let us do clean, inspectable work.

We will tell you up front roughly where the access openings need to be and what will be left open for the inspector. We make controlled cuts and leave them ready for patching. Drywall finishing and paint are usually handled separately, and we are clear about that boundary before we start so there are no surprises.

Repiping is permitted work in East Bay cities. We pull the permit, schedule the inspection, and leave the new lines open where the inspector needs to see them before anything gets closed up. That paper trail protects you when you sell the home, and it means the work was checked by someone other than the person who installed it.

If you have a single active leak or sudden total loss of water, treat it as an emergency and call us, because we are available 24/7 and stopping water damage comes first. A full repipe, on the other hand, is planned work we schedule with you. One thing that is not on us: if the low pressure or discoloration is happening at the street side or across your neighborhood, that can be a water main or utility issue, and the right first call is the water district, not a plumber.
