Signs you have a hidden leak
An unexplained jump in your water bill, the sound of running water when everything’s off, warm or damp spots on floors, mold or a musty smell, low water pressure, or a water meter that keeps moving when no fixtures are on. Any of these is worth a professional leak check before the damage grows.
Our leak detection & repair services
We locate leaks accurately before opening anything up, then repair or reroute the line. Common jobs include slab leaks under the foundation, pinhole and pipe leaks inside walls, leaking fixtures and supply lines, and outdoor/underground leaks. Finding the exact spot first means a smaller, cleaner, less expensive repair.
