Mould, Air Systems and Sensible Precautions

Where mould and an air system meet, the concern is distribution — spores moving from one damp room into the rest of the house.

What matters, and why.

The pathway

Growth near a return grille or in a damp ceiling void can be drawn into the system and distributed. This is why a mould problem in one bathroom sometimes smells like a whole-house problem.

Contain, then clean

The affected area is isolated before treatment so spores are not spread during the work itself. Doing it in the wrong order makes the situation worse.

The system afterwards

Where distribution is likely, filters are changed and the return and coil are cleaned after remediation, not before.

Being straight about evidence

Health effects of mould exposure vary considerably between individuals, and we are not qualified to assess them. If anyone in the household is unwell, that is a conversation for a doctor.

If this is something you would rather hand over, our mould treatment and deep cleaning is scoped at an inspection and confirmed in writing before any work begins. We will also tell you when a job does not need us.

Questions

Answered plainly.

Usually yes, to avoid distributing spores while work is in progress.

Surface sampling where there is visible growth. Formal air sampling requires an accredited lab and we refer you.

A single bathroom is often a day. Anything involving a cavity depends on the building work required.
