Leak Detection in Serramonte, Daly City, CA
Parts of the Serramonte tracts sit on slab, which changes leak detection entirely. A hot water line failing under concrete produces a warm floor patch and a rising bill long before anything is visible. We locate these electronically rather than opening concrete speculatively.
Do you find slab leaks in Serramonte?
Yes, and it is one of the more common calls here given the slab construction in parts of the tract. Electronic location pinpoints the line so any concrete work is targeted to a small area rather than exploratory.

What we find in these homes
- 1960s-era tract construction with largely original drain lines
- Water heaters and fixtures reaching end of service life together
- Slab-on-grade foundations in parts of the tract, which affects leak location
- Established landscaping near sewer laterals, a common root intrusion source
Signs worth calling about
- A water bill that jumped with nothing at home to explain it
- A hissing or dripping sound behind a wall or under the floor
- A warm spot on the floor, which often points to a hot water line under a slab
- A musty smell or damp patch that persists even on dry days

Leak Detection in Serramonte — FAQs
Do you find slab leaks in Serramonte?
Yes, and it is one of the more common calls here given the slab construction in parts of the tract. Electronic location pinpoints the line so any concrete work is targeted to a small area rather than exploratory.

Yes. Daly City Plumber Bros provides leak detection throughout Serramonte 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.
