San Francisco County · Detection
Find pool shell, plumbing, and equipment leaks before water loss becomes structural damage.
The Iqbal Family, who lives in Bayview, San Francisco, reached out after noticing rising water bills during pool season. San Francisco's cooler, fog-influenced microclimate means residential pools are far less common here than in almost any other major California city, so pool and spa leak calls in San Francisco concentrate on hot tubs and small in-ground spas rather than full backyard pools. Instead of guessing and re-testing for weeks, the location was confirmed on the first visit and handed straight to repair.

San Francisco's cooler, fog-influenced microclimate means residential pools are far less common here than in almost any other major California city, so pool and spa leak calls in San Francisco concentrate on hot tubs and small in-ground spas rather than full backyard pools.
Water service in San Francisco is provided by the SFPUC, and confirming whether an issue is on your private plumbing or the utility side of the meter is one of the first things we check.
With California's climate, pools and spas run for most of the year, which means even a small leak adds up fast in lost water and can eventually undermine the surrounding decking or yard. We test pool shells, skimmers, return lines, main drains, and equipment pad plumbing to determine whether water loss is from evaporation or an actual leak, and if it's a leak, exactly where.
We use a bucket test to separate evaporation from true leaks, dye testing to check skimmers and fittings, and pressure testing on plumbing lines. For suspected shell leaks, a dive inspection can visually confirm the leak point.

A technician arrives with acoustic listening equipment, thermal imaging, and pressure or camera tools matched to your specific leak type.
The leak's exact location is marked and explained to you in plain terms, so nothing gets opened up on a guess.
You receive a written diagnostic report you can hand to your plumber, restoration team, or insurance company, with repair or fix options discussed on the spot.
“Old Victorian with plaster walls everywhere, so I was dreading this. They used thermal imaging and found the leak behind one wall panel instead of opening up the whole room. Saved us a big repair bill.”
“Ground near our garage had been soft for a while. Turned out to be the main line. They marked the exact dig spot and our plumber only had to open a two-foot section instead of the whole path.”
“The floor in our hallway had a warm spot for weeks. They found the slab leak in under an hour with the listening equipment and marked a tiny area instead of tearing up the whole hallway. Huge relief.”
“Our water bill jumped for two months straight and we couldn't find why. Turned out it was a slow leak behind the water heater. Professional, on time, and explained everything on the spot.”
“Salt air had corroded a fitting outside near the meter box. They traced it with the acoustic equipment without digging up my whole side yard first. Appreciated the straightforward report.”
