WHAT WE DO

A specialist approach to damp, moisture 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.

WHY WE DO WHAT WE DO

What our clients say.


“I had a call from our disrepair contractor. I sent them your surveys to quote from. They wanted me to pass on their
thanks, as your surveys are very high quality and have all the information needed. This makes their job easier,
compared to other reports they receive.”

“We worked closely with JAG on an Ombudsman level case. JAG carried out the initial damp and mould survey, which
allowed our contractor to carry out root cause remedial works. We found that the resident was still suffering with a cough,
carrying out a post inspection survey, air test and the use of IoT sensor data, JAG helped us identify potential issues. We
were then able to educate and support our residents and satisfy the Ombudsman.”

"We have worked with JAG over an 18-month period, in the build-up to Awaab’s Law. JAG and James’ knowledge and input were invaluable. We are all learning every day, and having JAG as our damp and mould partner has made a difference to how we look at damp and mould when it comes to our homes and prioritising our residents’ health.”
