The linen closet in the hall has a gray band along the bottom of the back wall, and the baseboard gives when you press it. The tile outside the closet door has felt warm underfoot since late summer. The house is a 1960s ranch on a slab, and the copper under that slab is the copper it was built with.

Nothing gets cut until the walls are metered. A pin meter on the drywall and a non-invasive meter across the slab tell the crew how far the water traveled, which on a slab is usually farther sideways than the stain admits. They mark the line in the closet, in the hall, and in the bedroom that shares the wall, and they mark the floor where the slab reads wet.
Then the room is sealed. Plastic goes across the hall, the supply and return grilles in that wing are taped over, and a HEPA air scrubber is ducted out a bedroom window so the closet runs under negative pressure. Dust from the demolition stays behind the plastic instead of reaching the kitchen.
If the floor is warm, a hot line under the slab is the likely source, and a plumber needs to find and reroute it; that work runs alongside the mold work, not after it. Photograph the baseboard, the wall, and the warm tile. Do not pull the baseboard or cut the drywall yourself; a wet board sheds spores when it tears, and without plastic up they ride the air handler through the house.
Leave the air conditioning running with the fan set to auto, not on. Skip the bleach: it wets the paper face and leaves the growth inside the gypsum. If the wet wall backs onto a bathroom or the kitchen instead of a closet, check under the sink and behind the fridge for a swollen cabinet floor.
The wet drywall, the baseboard, and whatever insulation is in the wall come out to a margin above the meter line and are bagged before they leave the plastic. Studs, bottom plate, and slab stay in place when they read dry after the cleaning. A bottom plate that sat in slab water for a season sometimes has to be cut and sistered, and the crew says so before they do it.
After demolition every surface inside the plastic is HEPA-vacuumed and wiped. Air movers and a dehumidifier run until the framing and the slab read dry, which on a long slab leak can take most of a week. If the growth has reached the ducts or the attic, see HVAC mold cleaning or attic mold remediation. When the wet footprint runs into three or four rooms, the job is whole-home mold remediation. Closing the wall afterward is mold damage repair.
Escondido's 1950s to 1970s ranches in Felicita, Mountain View, and the flats around Grand Avenue were plumbed with copper run under the slab, and after sixty years of hard inland water those lines pinhole from the inside. Garage water heaters in the same houses are often on their third replacement, and a tank that weeps at the seam wets the shared wall long before it floods the garage. Houses from the 1990s on in Rancho San Pasqual and East Valley have newer pipe but add an attic air handler to the list of suspects.
California issues no mold license. Removal is a trade the provider represents its own training in; replacing drywall, cabinets, and trim is contractor work under the Contractors State License Board, and a rebuild that touches plumbing or electrical needs a permit through the City of Escondido or San Diego County depending on where the house sits. Most California homeowner policies pay for a sudden leak and exclude a slow one, so tell your adjuster the date you first felt the warm tile.
Have the address, which pipe or appliance you suspect, and how long the wall has looked this way. Mention whether a plumber has located the line yet, and whether the spot has been painted over before. Call (760) 546-5839.
