What Qualifies As An Emergency
Any active, unidentified water intrusion qualifies. If any of these match, this is the right emergency page. Not sure it qualifies? See our emergency overview for the full list.
- Water appearing with no visible source — walls, floors, or ceilings wetting with no fixture running
- Multiple rooms affected simultaneously, suggesting a supply-line failure rather than a fixture drip
- The water meter spinning with everything off, confirming a hidden pressurized loss
- Water spreading visibly while you watch — the source is active and must be found tonight
Warning Signs
Warning Signs Not To Ignore
Unidentified water is automatically urgent — the damage compounds while the source hides.
Spreading Across Rooms
Multi-room spread means a supply line, not a fixture. Supply failures run at full pressure until the main is shut.
Meter Spinning Wildly
A fast-spinning meter quantifies the emergency — hundreds of gallons per hour in the worst cases. Shut the main and call.
Sounds Without Fixtures
Hissing or rushing inside walls with nothing running is a pressurized break announcing itself. Believe it.
Before We Arrive
What To Do Before We Arrive
Stabilize first, investigate second — and let the equipment do the investigating.
Shut Off The Main
With an unknown source, the main shutoff is your best move — it stops all pressurized flow at once, whatever the source.
Map The Wet Areas
Note which rooms are wet and where the water seems newest. The pattern's center points toward the source — tell us on arrival.
Protect Valuables
Move electronics, documents, and furniture from wet and adjacent rooms. Water travels; the next room is already at risk.
Do Not Open Walls
Resist exploratory demolition — it rarely reveals the source and always adds repair cost. Our equipment finds it without openings.
Safety Guidance
Safety Guidance
Unknown-source water deserves maximum caution until identified.
Treat Wet Electrics As Live
Water near outlets, switches, or panels is an electrocution risk. Switch off affected breakers or keep clear entirely.
Beware Of Ceiling Collapse
Waterlogged drywall is heavy and fails suddenly. Keep people out from under sagging or bulging ceilings.
Do Not Drink Or Use The Water
Until the source is identified, assume contamination — especially if the water is discolored or odorous.
The Problem, Understood
An unidentified water emergency is uniquely stressful because every response depends on the source — and the source is hidden. It could be a burst supply line inside a wall, a failed water heater, a slab break, or an appliance supply that let go. Each demands a different shutoff and a different repair, and guessing wrong wastes the critical first hour. Our emergency protocol is built for exactly this: a systematic sweep with acoustic listening, thermal imaging, and moisture mapping that converges on the source within the visit. We do not guess; we triangulate — and the emergency ends when the water stops, not when someone theorizes. The properties that fare best are the ones where the main was shut off early — a closed main turns even an unidentified leak from an active emergency into a stable puzzle.
Our Process
How Our Emergency Response Works
Unknown source in, known source out — usually within a single visit. Our has handled Chelsea emergencies for thirteen years.
1
You Call — We Dispatch
Describe the water: where, how fast, any sounds or smells. We give shutoff guidance matched to your description and dispatch immediately.
2
Systematic Sweep
On arrival we work the property methodically — meter test, thermal scan, acoustic sweep — eliminating zones until the source zone remains.
3
Source Triangulated
Multiple methods converge on the exact failure: the split line, the failed fitting, the burst heater. Marked, photographed, explained.
4
Water Stopped, Report Written
We stop the active loss and document everything — location, cause, and recommended repair — in a written report.
What Happens Next
With the source found and the water stopped, the emergency downgrades to a repair project. Our report tells your plumber exactly what failed and where, which keeps the repair surgical. If the failure reveals a systemic issue — aging supply lines throughout, for example — we will say so honestly, and our standard detection service can survey the rest of the property before the next emergency chooses its own timing.

Water Leak Detection
Our core specialty: acoustic sensors, thermal imaging, and tracer gas find hidden leaks behind walls, under floors, and underground — accurately, non-invasively, in a single visit.

Once the source is identified, it is often one of these — each has its own emergency page.
Emergency Slab Leak
Warm spots on floors, rising water bills, or the sound of running water under concrete all point to a slab leak. We trace it precisely so repairs open the smallest area.
Emergency Wall Leak
Damp patches, bubbling paint, or a musty smell can hide a wall leak. We pinpoint the exact pipe or entry point behind drywall so repairs stay small and surgical.
Emergency Ceiling Leak
A ceiling stain that grows, drips, or darkens needs fast answers. We trace ceiling leaks to the true source — roof, pipe, or fixture — before damage spreads.

FAQs
Emergency Questions
Straight answers for the most stressful leak call there is. For non-urgent questions, see our standard service page.
Yes — that is the core of what we do. Acoustic listening hears pressurized leaks inside walls and slabs; thermal imaging sees the temperature signature of hidden moisture. Unknown-source emergencies are our most common call.
Most emergency sources are located within the visit. Complex multi-zone properties take longer, but we work systematically until the source is found — we do not leave you guessing.
Yes. The main shutoff stops all pressurized flow regardless of source. It is the safest first move in any unidentified-water emergency.
No. Emergency detection is non-invasive. We locate the source with equipment; any opening for repair happens later, surgically, at the marked point.
We determine that too — service lines, irrigation, and groundwater are all in our diagnostic scope. The sweep covers the property's full water path.
We work systematically until the source is found — unknown-source calls do not end in shrugs. Our multi-method sweep (acoustic, thermal, moisture mapping) converges on even well-hidden failures. In the rare case of a truly inaccessible void, we stabilize the water, document everything, and schedule the follow-up with a defined plan — never a guess.
