Where Walnut Creek homes leak

Walnut Creek grew fast in the 1950s, 60s and 70s. The typical house from those years is a single-story ranch on a concrete slab, with copper water lines under the floor. That is true in Larkey Park, Parkmead, Northgate and much of the rest of the city. Copper of that age develops pinholes, and under a slab nobody sees them.

The other common leak here is the main water line between the meter and the house. On large lots with mature oaks that line can be long, and a leak in it shows up as a soggy patch of lawn or simply as a high bill.

What to watch for

Inside: a warm area of floor, flooring that lifts or darkens, a faint hiss in a quiet house, or hot water that runs out sooner than it used to. Outside: wet ground in dry weather. On paper: a water bill that climbs while your habits stay the same. Any of these is reason enough to call (510) 626-9773.

How we work

We test your water lines to confirm the leak and pin down which line it is on and where. We do that before any floor, wall or yard is opened. Then we show you what we found and go through the ways to repair it:

  • a spot repair at the leak,
  • a new line routed around the slab through walls or attic,
  • or a repipe if the home has a history of leaks.

Each comes with its cost. You decide.

Condos and shared buildings

In condos and attached homes, a leak can cross property lines: your pipe, a neighbor's ceiling. Tell us when you call if you are in an association, and whether it needs notice before plumbing work. We can describe what we found in plain words for you to pass on.

Walnut Creek leak detection questions

How do you find a leak under a concrete floor?

We test the water lines to confirm the leak and narrow down its location before opening anything. You see what we found before any repair is proposed.

My water bill doubled. Is that a leak?

It may be. A hidden leak in a slab line or the main line to the house is a common cause. Call and we can check.

Can a leak in the yard line be fixed without digging up the whole lawn?

Often, yes. Once the leak is located, the repair can usually be limited to that area, or the line can be replaced with little trenching.

Do you work in gated and condo communities?

Yes. Tell us about gate access and any association rules when you call.

Is the estimate free?

Yes. Estimates are free.
