Leak Detection in Annapolis, MD
A hidden leak wastes water, damages structure and drives your bill up for months before it announces itself. Heidler, Inc. finds it without tearing your home apart — electronic, acoustic and thermal detection, then a plain answer about what it will take to fix.
Finding What You Can't See
Most of the plumbing in your home is hidden — inside walls, under floors, beneath the slab, or buried in the yard between the meter and the house. When something fails in those places, the leak can run for months before enough damage accumulates for anyone to notice.
The cost of that delay is rarely the water. It's the drywall, the framing, the flooring, the insulation and occasionally the foundation. It's also, in a surprising number of cases, a septic drain field being hydraulically overloaded by a leak nobody knew about.
We locate leaks using acoustic listening equipment that hears water escaping under pressure, thermal imaging that shows temperature differences through finished surfaces, and pressure testing that isolates which line is losing water. None of it requires opening anything speculatively.
Where Leaks Hide in Anne Arundel County Homes
The pattern varies with construction. In the older housing around Glen Burnie, Annapolis and Bowie, leaks concentrate at the junctions in galvanized and mixed-material supply runs. In the slab-built newer developments in Odenton and Severn, they hide in slab-embedded lines. On the larger Gambrills and Millersville properties, long buried supply runs between well or meter and house are a common and expensive place to guess wrong.
Accurate location matters most where access is worst. Finding a leak precisely in a buried line or under a slab turns a speculative excavation into a targeted repair, and that difference is usually far larger than the cost of the detection itself.

When to Call for Leak Detection
Your Water Bill Climbed Without Explanation
UrgentA steady unexplained increase is the most reliable early indicator of a hidden leak, because it runs continuously while a visible drip doesn't.
The Meter Moves With Everything Off
UrgentShut every fixture and check the meter. Movement means water is escaping somewhere between the meter and your fixtures.
Musty Smell or Unexplained Damp
Persistent mustiness, staining on drywall, or a patch of floor that never quite dries all point to water where it shouldn't be.
A Green Patch or Soft Ground in the Yard
Grass growing faster in one strip, or ground that stays soft in dry weather, often traces the buried supply or sewer line beneath it.

Leak Detection FAQs
How can I check for a leak myself?
Turn off every fixture and appliance that uses water, then watch your meter. If it's still moving, you have a leak somewhere on your side of it. That simple test won't tell you where, but it does confirm whether it's worth investigating.
Can you find a leak without damaging my walls?
That's the entire point of the equipment. Acoustic listening, thermal imaging and pressure testing locate the failure through finished surfaces, so the only opening made is the one needed for the actual repair.
Can you find a leak in a buried line in my yard?
Yes, and it's where accurate detection pays off most. Long buried runs are common on Gambrills and Millersville properties, and pinpointing the failure turns a long speculative trench into a targeted dig.
How much water does a hidden leak actually waste?
More than most people expect — a continuous small leak can run into thousands of gallons a month. On a septic property it's worse than a bill problem, because that volume hydraulically overloads the drain field.
Is a hidden leak urgent?
Yes, because it never stops. The water itself is cheap; the framing, drywall, flooring and foundation damage it causes while you decide is not.
