Thermal and moisture mapping to locate hidden water and track the drying process.
You cannot dry what you cannot measure. Moisture mapping combines professional moisture meters with thermal imaging cameras to create a detailed map of every wet area in your property — including hidden moisture behind walls, under floors, and in ceiling cavities. This data guides the drying process, prevents missed wet spots, and provides documented proof for insurance claims.
Moisture mapping is the difference between guessing where the water is and knowing. After a water event, visible moisture on the surface is only part of the picture. Water travels along framing, through subfloors, and into cavities where it cannot be seen. A moisture map finds every wet area, records the moisture level in each material, and tracks the drying progress until every material reaches its target moisture content. Without a moisture map, restoration crews are drying blind.
Without moisture mapping, you are guessing. Hidden moisture leads to:
We test every potentially affected area using pin-type and pinless moisture meters. Readings are taken at the surface and at depth (behind baseboards, inside wall cavities, above ceilings).
A FLIR thermal camera scans all surfaces to detect temperature differences caused by moisture. Wet areas appear cooler than dry areas, revealing hidden moisture behind finished surfaces.
Every reading is logged with location, material type, and moisture content. The data is compiled into a moisture map that shows:
During drying, we re-test every monitoring point every 24 hours. The drying curve tracks progress and identifies areas that are drying slowly or need additional equipment.
When all monitoring points reach the target moisture content (per IICRC S500 standards), we verify the space is dry and provide the final moisture map for your records and insurance documentation.
| Equipment | What It Measures |
|---|---|
| Pin-type moisture meters | Moisture content at specific points using two-pin probes |
| Pinless moisture meters | Non-invasive moisture detection across larger areas |
| Thermal imaging cameras | Temperature differences indicating hidden moisture |
| Hygrometers | Ambient temperature and relative humidity |
| Data loggers | Continuous monitoring of temperature and humidity over time |
| Material | Dry Target | Concern Level | Action Required |
|---|---|---|---|
| Wood framing | Below 15% MC | 15–19% MC | Drying if above 15% |
| Drywall | Below 1% MC | 1–2% MC | Remove and replace if saturated |
| Concrete | Below 4% MC | 4–6% MC | Drying if above 4% |
| Plywood subfloor | Below 15% MC | 15–19% MC | Drying or replacement |
| OSB | Below 15% MC | 15–19% MC | Drying or replacement |
| Carpet padding | Below 1% MC | Above 1% MC | Replacement if saturated |
| Service Item | Typical Cost Range | What’s Included |
|---|---|---|
| Initial moisture survey | $200 – $500 | Full property scan, thermal imaging, moisture map |
| Daily monitoring (per visit) | $100 – $200 | Re-test every monitoring point, drying curve update |
| Final verification | $100 – $250 | Confirmation of dry targets, final moisture map report |
| Post-remediation verification | $200 – $400 | Final inspection after mold remediation or restoration |
Expert tip: Thermal imaging reveals moisture behind finished surfaces, but it has a limitation — it measures surface temperature, not moisture content. A thermal image that shows a cool area on a wall tells you there may be moisture behind it, but only a moisture meter confirms the material is actually wet. Both tools are needed for a complete moisture map.
Moisture mapping techniques are the same everywhere, but the baseline moisture content of building materials varies by climate. In humid southern states, wood naturally holds higher moisture content, so the dry target must account for the local equilibrium moisture content. In arid southwestern states, the dry target is lower, and materials that would be considered dry in the Southeast may still be above the local standard. Our local crews calibrate their moisture meters and drying targets to the regional climate so the moisture map is accurate for your area.

Moisture mapping is the process of testing and recording moisture levels throughout a building using pin-type and pinless moisture meters. Combined with thermal imaging, it creates a visual map of where water is present — including hidden moisture behind walls and under floors.
Moisture mapping reveals the full extent of water damage, including areas that are not visible. It guides the drying process, prevents missed wet spots, and provides documentation for insurance claims.
Moisture readings are taken every 24 hours at every monitoring point. The data is plotted on a drying curve to track progress and determine when materials are dry.
Yes. Thermal imaging detects temperature differences through tile, stone, and concrete. Moisture mapping with non-invasive meters can detect moisture behind finished surfaces without damaging the material.
An initial moisture survey and thermal imaging scan runs $200 to $500 for a typical residential property. Daily monitoring during drying adds $100 to $200 per visit. A free inspection gives you a written estimate.
Yes. Moisture mapping is a standard part of professional water damage restoration and is included in the insurance claim documentation. The moisture map provides the evidence your adjuster needs to approve the drying scope.
Our certified technicians respond fast, assess the damage, and give you a clear plan — with no obligation and no up-front cost.
