Leak Detection in Westlake, Daly City, CA
Westlake homes were built in a compressed postwar period, and many still run original galvanized supply inside the walls. Galvanized fails by thinning from the inside, so the first sign is usually a pinhole behind plaster rather than anything visible. Acoustic detection matters more here than in newer stock because there is rarely an accessible run to inspect.
Why are leaks harder to find in Westlake homes?
Because the original galvanized supply is largely concealed and fails from the inside out. There is often no visible run to check, so we locate acoustically and confirm with thermal imaging before opening anything.

Leak Detection in Westlake — FAQs
Why are leaks harder to find in Westlake homes?
Because the original galvanized supply is largely concealed and fails from the inside out. There is often no visible run to check, so we locate acoustically and confirm with thermal imaging before opening anything.
Do you provide leak detection in Westlake?
Yes. Daly City Plumber Bros provides leak detection throughout Westlake and all of Daly City, CA. You get a free estimate and a upfront price before any work begins.
Will you cut into my walls to find the leak?
Not until we're confident where the leak actually is. Acoustic and thermal tools narrow it down first, so any opening we make is small and targeted.
How do you tell a real leak from Daly City fog moisture?
Fog damp is surface-level and usually seasonal. A plumbing leak shows a pressure drop we can measure at the meter, and the moisture pattern points back to a supply line rather than an exterior wall.
