Leak Detection in Top of the Hill, Daly City, CA
Top of the Hill homes have often been renovated more than once, leaving copper, galvanized, and sometimes newer PEX in the same house. Leaks concentrate at the transitions between those materials, which are rarely documented and almost never where a homeowner expects.
My Top of the Hill home has mixed plumbing — where do leaks usually start?
At the joints where different pipe materials meet. Those transitions corrode faster than either material alone, and in a multiply-renovated home they can be anywhere. We trace the system rather than guessing.

Leak Detection in Top of the Hill — FAQs
My Top of the Hill home has mixed plumbing — where do leaks usually start?
At the joints where different pipe materials meet. Those transitions corrode faster than either material alone, and in a multiply-renovated home they can be anywhere. We trace the system rather than guessing.
Do you provide leak detection in Top of the Hill?
Yes. Daly City Plumber Bros provides leak detection throughout Top of the Hill 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.
