Water Leak Search & Investigation
We find the leak nobody else could.
Roof, facade, window, deck, or pipe — when water keeps showing up and the source keeps hiding, we run a systematic leak search: isolation, controlled water testing, moisture mapping, and a written Cause & Origin findings report. Then the same contractor fixes the source and restores the damage. Washington, DC, Maryland, Northern Virginia, and Hampton Roads — 24/7 for active leaks.

Is it a leak?
The signs water leaves behind
- A water bill climbing with no change in how you live
- A stain that comes back after it's been painted over — twice
- A ceiling mark that appears only after rain — the classic signature of a roof, facade, or window leak, not a pipe
- A damp spot that never dries, or stays wet in dry weather — usually supply plumbing
- Musty odor, bubbling paint, cupping floorboards — moisture working inside the assembly
- Water in a unit with no plumbing above it — the dispute-starter in condo buildings
Two checks before you pay anyone
1. The meter test. Turn off every fixture and appliance that uses water. Watch your water meter's leak indicator for 30 minutes. If it moves, water is leaving a pressurized line somewhere — that's a plumbing-side leak.
2. The rain log. Note exactly when the water appears. Only during or after rain — and worse with wind from one direction? That points at the building envelope: roof, parapet, facade, or window. Steady regardless of weather? Think plumbing.
Whatever you learn, tell us. It narrows the search, shortens the visit, and lowers the bill — which is the point.
How a leak search works
Isolate. Test. Prove. Fix.
Opinions don't settle a mystery leak — evidence does. Every investigation runs the same four-step discipline.
- Systematic inspection & moisture mapping. We trace the wet path through the assembly — ceiling to cavity to exterior — with moisture readings at each point, and rule suspects in or out before any water flows.
- Controlled water testing. Where the source is hidden or disputed, we wet one suspect at a time — a window, a parapet, a flashing detail, a riser — in a controlled sequence, until the entry point reproduces the leak in front of us. One suspect, one test, no guessing.
- The findings report. The investigation closes with written Cause & Origin documentation: photos, moisture readings, test methodology, the confirmed source, the path of travel, and a scoped repair recommendation — a document built for insurance adjusters, condo boards, property managers, and counsel.
- The repair, under the same scope. The contractor who proved the source corrects it — roofing, facade, flashing, or plumbing coordination — then restores the ceilings, walls, and finishes. If growth is found along the way, our DOEE mold license covers assessment, remediation, and clearance without bringing in a second company.
Honest routing
A leak search is only worth paying for from the right specialist
Three kinds of companies find leaks, and they are not interchangeable. Here's who to call for what — including when it isn't us.
A plumbing leak
Constant drip, hissing line, meter spinning with everything off. A plumber or an acoustic leak-detection firm will find a pressurized-pipe leak fast — that's their equipment's home turf. If your leak turns out to be this, we'll tell you on the first visit instead of billing you for a search you don't need.
An underground service line
Soggy yard, wet pavement, loss between the meter and the building. That's a job for an underground utility-locating specialist with ground acoustics — a different trade with different gear. Call us and we'll point you to one rather than dig blind.
A building leak of unknown origin
Rain-only stains. Unit-to-unit water with the source disputed. The leak that's already outlasted two contractors. Water with no plumbing above it. This is the work we built the method for — envelope and plumbing suspects tested together, settled in writing.
Documentation that works
Built for adjusters, boards & attorneys
A leak search often has an audience beyond the property owner: an insurance adjuster deciding a claim, a condo board allocating responsibility between unit and association, or counsel on either side of a dispute. Our findings reports are written as Cause & Origin documentation — methodology, evidence, and conclusions laid out so a reader who wasn't there can rely on them.
We work alongside your adjuster, answer board questions on the record, and keep the paper trail complete from first reading to final clearance. When the question is "who pays," the file we leave behind is the answer's foundation.
Where we do this work
Rowhouses and condo buildings across Washington — Columbia Heights, Capitol Hill, Brookland, Mount Pleasant, Petworth, Adams Morgan, Shaw — plus Arlington, Alexandria, Takoma Park and the Maryland suburbs, and the Hampton Roads market in Virginia.
DC's older housing stock is where mystery leaks live: parapet walls, layered flat roofs, brick facades with century-old flashing, and stacked units where one owner's problem starts in another owner's walls. It's most of what we investigate.
