Fixture, fitting, and in-wall pipe repairs once the leak's exact location is confirmed.
Petra Q., a SoMa, San Francisco homeowner, had been living with a warm spot on the floor that didn't make sense for the season for weeks before calling us. Repairs in San Francisco's older plaster-walled homes require more careful access planning than a typical drywall repair, since plaster doesn't patch the same way and matching the surrounding wall texture is a real part of the job once the plumbing itself is fixed. The leak was marked in that same visit, and the repair crew only had to open a small section instead of the whole area.

Repairs in San Francisco's older plaster-walled homes require more careful access planning than a typical drywall repair, since plaster doesn't patch the same way and matching the surrounding wall texture is a real part of the job once the plumbing itself is fixed.
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.
Interior water leak repairs range from a simple fitting or valve replacement to a targeted section of wall or ceiling pipe being cut out and replaced. Because the leak has already been located precisely, the repair scope is usually narrow: open the smallest access point needed, replace or reseal the failed section, and confirm the fix holds under pressure before any drywall or finish work goes back.
We confirm the repair holds under normal water pressure before closing up any access point, and provide a written summary of the work for your records or for your insurance claim if applicable.

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.”
