WHAT WE DO

A specialist approach to moisture, damp and mould.

JAG is a specialist consultancy. We diagnose why moisture problems occur — combining building science, environmental data and on-site investigation to provide independent answers, not contractor estimates.

CASE STUDY

Discreet Air Testing for a High-Net-Worth Residence.

JAG carried out air and surface testing across a large residential property following historic damp and mould concerns. Testing across six rooms and AC unit vents found acceptable mould spore levels, giving the client reassurance and verified environmental data to support conversations with medical advisors.

Scope of works

  • Carry out Air Testing to 6 rooms in the property.

  • Carry out surface sampling (swabs) on the AC unit vents within the master suite and walk-in wardrobe.

Findings

  • All sampled areas returned acceptable mould spore levels, with no indication of abnormal mould presence.

  • AC unit vent surface sampling showed no significant mould prescence.

Key outcomes

The results reassured the client that mould growth was at normal levels and allowed the client to engage with their GP and medical advisors using verified environmental data.
