I noticed my water bill had nearly doubled over three months but could not find any visible leaks. Professional Leak Detection came out, used their thermal camera equipment, and found a hidden pipe leak inside our concrete slab. They repaired it with minimal disruption to our flooring. Fair pricing, honest team, and excellent results.
