Your routine has not changed but the utility says you used far more. That gap has to go somewhere.
A leaking hot line heats the concrete above it. One homeowner measured 90°F there against 73°F elsewhere.
Moisture that wicks up at a baseboard, with no plumbing fixture nearby, is often coming from below.
Water washing soil out from under a slab can let it settle, and hard flooring shows it first.
Baseboards swelling or staining
Trim that darkens or bulges at floor level.
Water sounds with everything off
A faint hiss or trickle in a wall or under the floor at a quiet hour.
Hot water running short
Showers go lukewarm sooner than they used to.

The method
Booking slab leak detection in Paramount, CA gets you these checks, in this order, with notes you keep at the end.
Read the meter with the house silent
Gauge test on an outside tap
With the main closed for fifteen minutes, a gauge threaded onto an outdoor tap shows whether pressure falls. A drop means water is escaping even if the meter hardly registers it.
Split hot from cold
Isolate the failing branch
Where the plumbing allows, each run is capped and tested on its own so the search is limited to the one line that is actually leaking.
Listen through the concrete
Thermal scan on hot lines
Heat escaping from a failed hot pipe shows on a thermal camera as a glow under tile or carpet, backing up what the microphones picked up.

Call (708) 982-5593Expect $150 to $400 for slab leak detection in Paramount, CA, agreed before the visit. The price covers every test in the sequence and a taped location, anywhere in ZIP code 90723 in Paramount.
They confirm the loss at the meter, test pressure with a gauge, separate hot from cold, isolate the failing branch, then use ground microphones and thermal imaging to find the exact spot.
Very much so. Leaks on the cold side stay invisible because they add no warmth, and the water can soak away into the ground rather than show up indoors.
Usually it is urgent, not an emergency. The water keeps flowing and the ground under the floor keeps getting wetter, so book soon, and close the main if water is coming up.
Phone (708) 982-5593, describe what you are seeing, and leave the call with a price and a time.
