Leak Detection & Repair
Fast, accurate water leak detection before it damages floors, walls, and ceilings, using professional acoustic and moisture detection equipment.
Find It Before It Spreads
Accurate Leak Detection, Targeted Repairs
Even a small leak can do major damage if it’s left to run. Mold behind walls, warped flooring, ruined ceilings. Most of it is preventable when the leak is found quickly.
We use professional-grade water leak detection equipment. Acoustic listening devices, moisture meters, and pressure testing. To locate the source accurately, without ripping into walls on a guess.
Whether the source is a wall hydrant, sillcock, hose bib, or hidden pipe, we identify the source, explain what we found, and lay out the repair options. Homeowners across Catonsville, Baltimore County, and Howard County call us for prompt water leak detection, and we provide upfront estimates before any repair begins.

Frequently Asked Questions
How do you find a hidden leak?
We use acoustic and electronic leak-detection equipment to pinpoint leaks inside walls, under floors, or beneath the slab. Without tearing out finishes to look.
What are the signs of a hidden leak?
An unexplained high water bill, musty smells or mold, warm or damp spots, peeling paint, or the sound of running water when nothing is on.
Can a small leak really cause damage?
Yes. Slow leaks feed mold, rot framing, and ruin finishes long before they’re obvious. Catching them early is far cheaper than the repairs they cause.
Do you repair slab leaks too?
We do. See our dedicated slab leak repair service for leaks beneath the foundation.
Should I shut my water off if I suspect a leak?
If you see active water or a fast-climbing meter, yes. Shut off the main and call (410) 242-3111.
Do you offer gas leak detection?
Yes. A suspected gas leak is a safety issue, so leave the area first, then call us. We handle gas leak detection through our gas services, locate the source, and make the line safe.
