Odour before appearance
A musty smell frequently arrives before any visible sign. It indicates microbial activity in damp material that has not yet stained a surface.

Nail pops, bubbling paint, lifting laminate seams and swollen trim all point to moisture behind or beneath the finish.
- Cool patches on walls with no other explanation
- Baseboards separating from the wall
- Floor squeaks or softness that appeared recently
Confirming suspicion
Thermal imaging highlights anomalies and moisture meters confirm them. Neither alone tells the whole story, which is why they are used together.
