How we handle slab leak water damage in Pasadena
Call and dispatch
A real person answers 24/7 and the nearest Pasadena crew rolls with pumps, air movers, and moisture meters.
On-site assessment
We trace the source and the full reach of the water, including what soaked into subfloor, plaster, and wall cavities.
Extract and dry
We pull the standing water, then run air movers and dehumidifiers to a verified dry standard, not just the surface.
Verify and bill
We log moisture readings until the structure reads truly dry, then document the loss and bill your carrier directly.
A slab leak can run for weeks under your floor before you see it, quietly soaking the slab, subfloor, and framing while your water bill climbs. Our crew answers live around the clock and reaches homes across Pasadena and the west San Gabriel Valley in 30 to 60 minutes. SOS Restoration handles the water damage side, the detection assist, extraction, and structural dry-out, and coordinates a licensed plumber for the pipe repair. Call (626) 314-6471.
Signs you have a slab leak
A slab leak sits below the concrete, so you read it from the clues it leaves in the rooms above. Watch for any of these:
- A warm patch on the floor, which points to a hot-water line failing under the slab
- A water bill that jumps with no change in how your household uses water
- The sound of running water when every tap and toilet is shut off
- Flooring that cracks, lifts, buckles, or feels damp underfoot
- A musty or mildew smell that settles low near the floor
One sign can be minor. Two or three together usually mean water is escaping under the slab, and the sooner we map the wet area the less it spreads into your floors and lower walls.
Why Pasadena and San Gabriel Valley homes get slab leaks
The large postwar tracts in Hastings Ranch, Daisy Villa, and East Central Pasadena were built on concrete slabs with the copper supply lines run right through the slab, so a pinhole in that buried copper leaks straight into the foundation.
The valley's hard water carries a heavy mineral load that scales up those copper lines and corrodes them from the inside until they weep or split, and it shortens the life of water heaters in San Marino, Arcadia, and Chapman Woods garages. Pasadena Water and Power explains local water hardness and where to find your main shutoff.
What we do, and what a plumber does
We are the water damage crew, not the plumber. A licensed plumber reroutes or repairs the failed line under the slab, while our technicians find the wet area, pull the water out, dry the slab and subfloor, and stop mold before it starts. If the leak turns out to be an aging supply line inside a wall instead, our corroded and galvanized pipe cleanup crew works it the same way.
Because we do not sell the pipe repair, our only job is getting your home dry and the damage small, and we document every step so your claim moves.
Drying your floors, insurance, and getting started
Wherever we can, we dry hardwood and tile in place rather than tearing them out, which matters in older Pasadena homes with original oak floors and mid-century tile over slab. Trapped moisture under a floor is how a hidden slab leak turns into mold, so once the structure reads dry we confirm it and, if needed, our mold remediation team treats any affected area. The EPA guide to mold covers why fast drying stops mold under a floor.
Sudden slab-leak water damage is covered on most homeowners policies even when the pipe repair itself is not, and access and tear-out are often included. We record the loss with dated photos and moisture readings so the sudden nature is clear, and our structural drying crew logs the dry-down to a verified standard. Call (626) 314-6471 and a crew will start right away.

☎ Call (626) 314-6471A warm floor and a high bill
The two clearest slab-leak tells are a warm patch on the floor over a hot-water line and a water bill that climbs while nothing about your household changed. Catch those early and we can often dry the floor in place. Left for months, the same leak can undermine flooring and feed mold beneath it, which is why a quick moisture check pays off.
"They traced our slab leak, dried the floor in place, and saved our original hardwood. The crew was quick, tidy, and walked us through every reading. A plumber fixed the pipe and they handled all of the water damage and the paperwork."

Common questions, answered
How do I know if I have a slab leak?
Common signs are a warm spot on the floor, a water bill that jumps for no reason, the sound of running water when everything is off, cracked or lifting flooring, and a musty smell near the floor. Two or three of those together usually mean a leak under the slab. Call (626) 314-6471 and we will find the wet area.
Do you repair the pipe under the slab?
No. A licensed plumber reroutes or repairs the pipe. We handle the water damage side, the detection assist, extraction, drying the slab and subfloor, and stopping mold, and we coordinate around the plumber so the area is dry and ready.
Why are slab leaks so common in Pasadena and San Gabriel Valley homes?
Many mid-century homes here were built on slabs with copper supply lines run through the concrete, and the hard local water corrodes that buried copper from the inside over the years, so pinhole leaks under the slab are one of the most common causes of interior water damage in the area.
Can a slab leak cause mold under my floors?
Yes. Water trapped under a floor keeps the subfloor and framing damp, and mold can start within 24 to 48 hours. Fast extraction and drying stop it, and we confirm the area is dry and treat anything at risk before we finish.
Will insurance cover slab-leak water damage?
Sudden slab-leak water damage is covered on most homeowners policies even when the pipe repair itself is not, and access and tear-out are often included. Gradual, long-term leaks are treated differently. We document the loss so the sudden nature is clear and bill most carriers directly.
Do you dry hardwood and tile in place or tear them out?
We dry floors in place wherever we can, which often saves original hardwood and mid-century tile over slab. We only remove what cannot be dried safely, and we tell you plainly which is which before any work.
How fast can you respond, and how long does the dry-out take?
We reach most of Pasadena and the San Gabriel Valley in 30 to 60 minutes. A typical slab-leak dry-out runs about three to five days depending on how long the leak ran and how far the water spread, and we monitor daily until it reads truly dry.
