Olson Superior Plumbing — Leak Detection Experts
Hidden leaks can cause serious damage before they're ever visible. We use advanced detection methods to locate the source accurately, then repair it with minimal disruption — so you get answers quickly and results that last.
Problems We Solve
We diagnose and resolve a wide range of leak issues, from visible water damage to hidden slab leaks and pressurized line failures.
Visible Water Intrusion
Water stains on walls, ceilings, or floors often indicate an active leak behind the surface that needs to be located and repaired.
Hidden Leaks
Leaks behind walls, under floors, or in ceilings can go undetected for weeks, causing mold growth and structural damage.
Slab Leaks
Leaks in pipes running beneath the concrete slab of your home can cause foundation damage, hot spots on floors, and unexplained water bills.
Pressurized Waterline Leaks
Leaks in pressurized supply lines can waste significant amounts of water and cause rapid damage if not detected and repaired quickly.
Drain Leaks
Leaks in drain, waste, and vent lines can cause slow water damage and create conditions for mold growth beneath floors and behind walls.
HVAC Condensation Leaks
Clogged or damaged condensation lines from HVAC systems can cause water pooling, ceiling stains, and moisture damage in attics and walls.
Roof Leak Identification
Not all water stains come from plumbing. We help identify whether the source is a plumbing leak or a roofing issue so you get the right solution.
Behavior-Based Leaks
Unexplained increases in water bills, the sound of running water when fixtures are off, or a water meter that won't stop spinning all suggest a hidden leak.
