Moisture mapping relies on calibrated pin and pinless meters plus thermal imaging to create a grid of readings across drywall, subfloors and concrete slabs common in Spokane homes. Technicians mark affected zones on-site so removal decisions stay limited to truly wet material rather than broad demolition. Readings taken behind baseboards and inside wall cavities often reveal water that traveled from roof leaks or burst pipes during freeze-thaw cycles typical of the Spokane area.
Edge cases include older plaster walls that hold moisture differently than modern drywall and multi-story buildings where water migrates downward through voids. We document relative humidity, temperature and moisture content percentages at each test point to satisfy insurance adjusters and local building officials. Skipping this step frequently leads to recurring mold growth weeks after visible drying appears complete.
Final maps include color-coded diagrams and digital photos tied to the property address. These records support claims and guide targeted drying equipment placement so restoration stays efficient and verifiable. All work occurs during posted business hours from our Spokane location so homeowners receive same-day findings when access is arranged promptly.
Moisture Mapping and Measurement Services We Offer
✓Thermal Imaging Scans
Infrared scans locate temperature differentials behind walls and under flooring to flag hidden moisture without demolition.
✓Pinless Moisture Meter Readings
Non-invasive surface scans provide rapid moisture percentages across large areas of drywall, wood and tile.
✓Concrete Slab Moisture Analysis
Specialized probes measure moisture vapor emission rates in slabs before new flooring installation or after flooding.
✓Wall Cavity Inspection
Small access points allow direct meter readings inside stud bays to confirm drying progress or hidden saturation.
✓Post-Drying Verification Mapping
Follow-up grid readings document that moisture levels have returned to normal before reconstruction begins.
✓Hardwood Floor Moisture Testing
Targeted readings under and between boards identify trapped water that can cause cupping or mold if left untreated.

How it works
- 1
Initial Site Walk-Through
Technician reviews water history with the owner and identifies likely entry points and migration paths.
- 2
Equipment Setup and Grid Layout
Test points are marked on a scaled floor plan using consistent spacing suited to the room size and construction type.
- 3
Data Collection
Multiple meter types record moisture content, relative humidity and thermal anomalies at each marked location.
- 4
Report Generation
Color-coded map, photos and numeric readings are compiled into a document delivered the same day when possible.
Pricing
Pricing depends on square footage surveyed, number of stories and access difficulty.
