Postwar homes, postwar pipe

San Lorenzo Village was built in the 1940s and 50s, thousands of homes in a few years. Their water lines are now around seventy years old where they have not been replaced. Many houses have been updated in pieces: a new kitchen here, a new bath there. The pipe between those updates is often still original.

That is where leaks start. Old steel pipe rusts thin from the inside. Old fittings give out where new pipe was joined to old.

How a leak shows itself

Sometimes it is plain: a stain spreading on a ceiling or wall. More often it is quiet. The water bill goes up. Pressure at the shower drops. A cabinet floor swells. A room smells damp. A patch of floor feels warm underfoot. If something like this has been nagging at you, it is worth having it checked before the damage grows.

What we do

We listen to what you have noticed, then test the water lines to confirm a leak and narrow down where it is. Nothing gets opened until we know. Once we have found it, you get a plain explanation and your choices:

  • repair the one bad section,
  • run a new line around it,
  • or, if the old pipe is failing in several places, repipe so you are done with leaks.

We give you the cost of each. Estimates are free.

San Lorenzo leak detection questions

Do you do leak detection in San Lorenzo?

Yes. San Lorenzo is next to our Hayward base and part of our regular service area.

Why is my water pressure low in an older home?

Old steel water pipe rusts on the inside and narrows, which lowers pressure. A hidden leak can do it too. We can check which it is.

Is it better to fix one leak or replace the old pipes?

It depends on the pipe. One leak in sound pipe is a simple repair. Several leaks in old steel pipe usually mean more are coming, and a repipe may cost less in the long run. We price both.

How soon can you come?

For an urgent leak, emergency arrival is 60–90 minutes, any time. For a leak that can wait, we book a visit that suits you.

Are you licensed?

Yes. California license CSLB #1156315 (C-36 plumbing).
