Mapping Moisture Under Tile Before Any Demolition
- When:
- Spring 2026
- Loss:
- Water damage in a master bathroom
Tile hides water. It is not permeable in any useful way, it sits on a mortar bed that holds moisture well, and it looks exactly the same wet or dry. On a bathroom loss, that means the tiled area you can see tells you almost nothing about the wet area you cannot.
So on this Eagle Mountain job the mapping came first. A penetrating moisture meter and a thermal imaging camera were used to trace how far water had migrated beneath the tile before a single piece of it was removed. The second bathroom and the adjoining hallway were inspected and documented as well, to establish where the loss stopped as much as where it reached.
Only then did demolition begin, against a known boundary: tile off the tub deck, surround, and floor, drywall back to the studs, subfloor and framing exposed and mapped again. Equipment ran on those readings until the structure was dry, then was cleaned and sanitized on the way out.
What the work involved
- Initial assessment with a penetrating moisture meter and thermal imaging camera to map migration under tile before any demolition
- Secondary bathroom and adjacent hallway also inspected and documented to confirm the extent of the loss
- Containment installed at the bathroom entry to protect the rest of the home during demolition
- Tile removed from the tub deck, shower surround, and floor
- Affected drywall removed to exposed studs
- Subfloor and framing exposed and moisture-mapped
- Air movers and dehumidification set, with monitoring readings on subfloor and framing over the following days
- All equipment cleaned and sanitized on removal
Result
Structure dried and released to reconstruction approximately one week after the initial inspection.
