Signs of Hidden Leaks

Unexplained water bill increases

Usage hasn't changed but your bill jumped? Even small hidden leaks waste thousands of gallons monthly.

Sounds of running water with everything off

Water moving somewhere it shouldn't. Could be in walls or under your slab.

Damp or warm spots on floors

Especially warm spots, which often indicate slab leaks from hot water lines under concrete.

Mold, mildew, or musty odors

Persistent moisture from hidden leaks creates perfect conditions for mold.

Low water pressure throughout the house

Sudden pressure drops sometimes indicate main line leaks.

Soggy yard areas when it hasn't rained

Underground or main line leaks creating telltale wet spots.

Leaks We Detect and Repair

Slab leaks

Water lines under concrete developing leaks from corrosion or ground shifting. Particularly destructive because they're hidden, continuous, and undermine your foundation.

Behind-wall leaks

Supply lines inside walls, especially in older homes. These create wall damage, mold, and structural issues if not caught quickly.

Underground and yard leaks

Main water lines and irrigation lines. Finding these requires expertise and specialized equipment.

Main line problems

Your main line connects your home to municipal supply. Tree root intrusion, corrosion, and ground movement all compromise main lines. Sometimes we repair damaged sections; other situations require full replacement.

How We Find Leaks

We don't randomly tear into walls or floors. We start systematically: reviewing water usage, inspecting visible plumbing, checking meter behavior, and listening for water movement. This often narrows the location before we use specialized electronic detection equipment and pressure testing. Four decades of experience matters — Brian and Damon know where to look, what patterns indicate what problems, and how to interpret subtle clues others miss.

Our goal: find the leak with minimal disruption to your home, then fix it correctly.
