Trusted San Rafael Water Leak Detection Pros — Find It, Fix It, Prevent It

Hidden water leaks in San Rafael are costly because they travel silently through walls and slabs. We combine
technology and craftsmanship to locate the problem precisely and stop the damage before it spreads.

Older bungalows and mid‑century homes benefit from proactive valve and supply line upgrades.

Hillside lots and longer plumbing runs can mask leaks until surfaces show damage.

Five clues you may have a hidden leak:

1. Water meter movement even when all fixtures are closed.

2. Hissing sounds behind walls or near fixtures when water is off.

3. Warm spots on floors or damp carpet over slab areas.

4. Unexplained spikes on your water bill despite normal use.

5. Mildew odors or persistent humidity in specific rooms.

Why leaks happen:

- Aging copper with pinhole corrosion from water chemistry.

- Over‑pressurized systems without a working PRV or expansion tank.

- Old galvanized piping rusting from the inside out.

- Slab movement and soil conditions stressing buried pipes.

Our step‑by‑step approach:

Step 1: Open a small access point and make a clean, permanent repair.

Step 2: Confirm with pressure testing or tracer gas for small, silent leaks.

Step 3: Isolate lines to narrow the suspect branch without opening walls.

Step 4: Acoustic listen and thermal scan to triangulate the leak position.

Step 5: Restore finishes neatly and verify with a final pressure test.

Prevention plan for peace of mind:

- Replace old angle stops and braided supplies proactively.

- Install leak alarms under sinks, behind washers, and near water heaters.

- Know where your main shut‑off is and make sure it turns easily.

- Keep water pressure in spec with a functional pressure‑reducing valve (PRV).

Case snapshot (San Rafael): A homeowner noticed a warm floor patch near the hallway. Thermal imaging confirmed
a hot‑side slab leak. We isolated the run, performed a clean access repair, and verified with a pressure hold
— all in one day.
