Understand the problem

What is Black Mould Removal & Prevention?

Black mould (commonly Aspergillus or Stachybotrys) grows wherever there is persistent moisture and poor ventilation. It releases spores that can affect indoor air quality and aggravate respiratory conditions, allergies and asthma. Because mould is a symptom of a moisture problem — usually condensation, but sometimes penetrating or rising damp — lasting removal depends on diagnosing and correcting that root cause, not just cleaning the visible growth.

Spot it early

The warning signs to look for

Catching the problem early keeps repairs simpler and less costly. If you notice any of these signs, it is worth booking a specialist survey before the damage spreads.

Local specialists

Black Mould Removal & Prevention across Bournemouth, Poole & the South Coast

If you're searching for mould removal in Bournemouth or need to remove black mould in Poole, Proofterior is your local specialist. We remove and prevent black mould across Bournemouth, Poole, Christchurch, Wimborne and the wider Dorset coast, along with Southampton and Winchester in Hampshire and Salisbury in Wiltshire. Coastal and older South Coast homes are especially prone to condensation and mould, so we don't just clean the surface — we fix the underlying moisture and ventilation problem so it stays gone for good.

Where we work

Covering Dorset, Hampshire & Wiltshire

Local knowledge, specialist expertise and lasting protection for the home you care about.

Common questions

Everything you might be wondering

Because cleaning removes the growth but not the cause. Mould returns wherever moisture and poor ventilation remain. We treat the surfaces and fix the underlying moisture problem so it stays away.

It can affect indoor air quality and aggravate respiratory conditions, allergies and asthma, so it should be dealt with promptly and properly rather than simply painted over.
