Inspections
Mould inspections and testing
Seven ways in, one approach: find the moisture, establish the cause, and sample only where samples answer a real question.
The short answer
Most jobs start with a mould inspection and moisture map. Air samples are added when mould is suspected but not visible, surface samples when you need to know whether a mark is mould, and clearance testing after works. Buyers, rentals and flood-affected homes each get a scope built around the decision they face.
| If you need to… | Start with |
|---|---|
| Find the cause of mould or a musty smell | Mould Inspection & Moisture Mapping |
| Check for hidden mould you can’t see | Air Sampling (Spore Trap) |
| Find out whether a stain is mould | Surface Sampling |
| Check a home before you buy | Pre-Purchase Inspection |
| Settle who is responsible in a rental | Rental & Tenancy Inspection |
| Find what is still wet after a flood or leak | After a Flood or Leak |
| Sign off works independently | Clearance Testing |
Mould Inspection & Moisture Mapping
Find where the mould is, how far it goes, and the moisture that is feeding it.
- Visual survey
- Pin and non-invasive moisture meters
- Thermal imaging
- Relative humidity and dew point readings
Air Sampling (Spore Trap)
Indoor air compared with outdoor air to show whether something inside is adding spores.
- Spore trap cassettes
- Calibrated air pump
- Outdoor control sample
- Laboratory microscopy
Surface Sampling
Confirms whether a mark is mould, and whether it is active growth or settled spores.
- Tape lift
- Swab
- Bulk material sample
- Direct microscopy
Pre-Purchase Inspection
Hidden damp and mould checked before settlement, while you still have options.
- Moisture meters
- Thermal imaging
- Subfloor and roof space check where safely accessible
- Optional spore trap air samples
Rental & Tenancy Inspection
An independent account of cause under the damp and mould minimum housing standard.
- Moisture meters
- Thermal imaging
- Relative humidity logging
- Optional air and surface samples
After a Flood or Leak
What is still wet, what has started growing, and documented results for the claim.
- Moisture mapping with reference readings
- Thermal imaging
- Air and surface samples
- Dated photographic record
Clearance Testing
Independent checks after works, before rooms are reoccupied or walls are closed up.
- Visual inspection
- Moisture readings against reference
- Post-works air samples
- Surface tape lifts
