Slab leaks hide under your foundation, so they're easy to miss until the damage adds up. Watch for these signs — if you notice one or more, get it checked early.
A slab leak runs 24/7 under the foundation, so a sudden jump in usage with no change in habits is one of the most common first signs.
With all fixtures closed, a faint hissing or running-water sound can mean water escaping from a line beneath the slab.
A leak in a hot-water line under the slab can heat the floor above it — noticeable on tile especially.
Water eroding the soil under a slab can shift the foundation, showing up as new cracks.
Persistent moisture under flooring can create mildew and odor even when you can't see standing water.
A significant leak can drop pressure throughout the home.
Noticing any of these? Early detection keeps a slab leak from becoming a foundation problem.
