Turn off every faucet and appliance, then check the water meter. If the dial keeps moving, water is running somewhere hidden, likely under the slab.
Put your hand on the warm area and nearby floor. A distinct warm patch, damp carpet, or a faint hiss of water are all clues worth noting for the plumber.
If you see pooling water, buckling floors, or a fast-moving meter, close the main shut-off valve to stop the damage until we arrive.
Move furniture and rugs off the warm spot so we can access it and check for moisture.
Many homes around Hollister and Ridgemark sit on concrete slab foundations with water lines run underneath. When a hot water line springs a leak down there, the heat rises through the concrete and shows up as a warm patch on tile or flooring. You might also notice a higher bill, weak hot water pressure, or the sound of water moving inside the walls.
Two things drive slab leaks in this area. Our hard, mineral-heavy water wears at pipe walls over the years, and the clay-heavy soil in the valley swells and shifts as it dries out and wets again, which stresses the pipes buried in the slab. A plumber uses electronic leak locating and, where needed, a camera to pin the exact spot before touching your floor. That means we open one small area instead of guessing across the room.
Call right away if the floor is buckling, baseboards are damp, or your meter spins with everything off. A slow slab leak can rot flooring and feed mold before you ever see standing water. Catching it early usually means a smaller repair and far less damage to deal with.
