Moisture Detection & Leak Location
Moisture detection is diagnostic work: finding water you cannot see and proving how far it has spread, without demolishing the building to look. Thermal imaging shows temperature anomalies, meters confirm whether those anomalies are actually wet, and the combination produces a moisture map you can act on — or use to show an adjuster exactly what is affected.
Common causes we see
- A water bill or meter reading that indicates a leak with no visible source
- Recurring stains, odours or paint failure with no obvious cause
- Disagreement with an insurer about the extent of a documented loss
- Pre-purchase concern about past water damage in a property
Signs you need Moisture Detection now
- A smell you can find but not locate
- Stains that reappear after being painted over
- Flooring movement or trim swelling in one area only
- Elevated indoor humidity with no explanation
Situations we handle every week
- You know something is leaking and three trades have not found it
- Your adjuster says only one room is affected and you believe it is three
- You are buying a house with a repaired water stain and want it verified
What happens if it is left alone
- Undetected leaks continue wetting concealed materials, so mold develops entirely out of sight
- Guessing at the wet area means either unnecessary demolition or leaving wet material behind a new wall
- Undocumented extent routinely results in an underpaid claim that cannot be reopened later
- A concealed leak that surfaces after a sale becomes a dispute nobody has evidence for
How we handle moisture detection
- 1Interview and historyWhen it started, what changed, what has already been repaired. Most hidden leaks are found faster by understanding the timeline than by sweeping the whole house.
- 2Thermal imaging surveyInfrared shows temperature differentials through finished surfaces, highlighting candidate areas without opening a single wall.
- 3Confirm with metersThermal anomalies can be cold air or insulation gaps. Non-invasive and penetrating meters confirm which are actually wet and how wet they are.
- 4Establish source and directionReadings are compared to find the wettest point and the direction of travel, which is what identifies the source rather than the symptom.
- 5Deliver a moisture mapYou receive a written report with a floor-plan map, thermal images, readings and a clear recommendation — suitable for an insurer or a real estate negotiation.
What's included
- Site history interview and walkthrough
- Full thermal imaging survey of suspect areas

Moisture Detection vs Water Damage Inspection
An inspection is the broader assessment: condition, cause, scope and cost. Detection is the focused technical task of locating and mapping moisture.
Moisture Detection vs Plumbing Leak Cleanup
Detection finds and proves it; the cleanup page covers the removal, drying and repair that follows.
Read before you decide
Moisture Detection — frequently asked
No, and anyone who says it can is overselling it. It reads surface temperature, and wet material behind a surface changes that temperature. That is why every thermal finding is confirmed with a moisture meter before we call it wet.

Water Damage Inspection
An inspection answers three questions in writing: what is damaged, what caused it, and what it will take to put right. It is the right first step when you are not in an emergency — buying a property, disputing a claim scope, checking work another contractor did, or deciding whether a stain is worth worrying about.
Plumbing Leak Cleanup
Slow plumbing leaks are the opposite problem to a burst line. The volume is tiny, the damage is concentrated, and the material has usually been wet long enough that the question is not just drying but whether growth has already started. Most of the work here is diagnostic: finding every place the drip landed before deciding what can be dried and what has to come out.
Slab Leak Cleanup
A slab leak releases water under the concrete, and by the time it appears at the edge of a room it has usually been running for weeks. Concrete stores that moisture and gives it back slowly, so slab losses need a genuinely different drying approach from a surface spill — and the flooring assembly above almost always has to come up to get at it.
Dehumidification Services
Dehumidification is what actually removes water from a building — air movers only push it into the air. This page covers dehumidification as a standalone service: chronic indoor humidity, damp enclosed spaces, post-loss moisture control after another contractor has left, and temporary humidity management during construction or storage.
