Mould & Damp Inspection in Plettenberg Bay
Mould in Plettenberg Bay is usually year-round rainfall and coastal timber decay. A diagnostic inspection establishes which of the three damp mechanisms is at work before you spend anything, because the repairs are completely different and the wrong one is the most common expensive mistake. Expect R1,800 to R4,500 and a written report within 48 hours.
What causes mould in Plettenberg Bay
Year-round rainfall and coastal timber decay. Rain falls here through every season rather than in one window, so nothing gets a long dry spell to recover in. Steep forested sites stay shaded and wet, and a large share of the stock is holiday property standing closed for months at a time.
Predominantly second homes standing empty for long stretches, with thatch and timber decks under coastal exposure.
How to tell which type you have
Timber decay at deck bearers, window joinery and balustrade fixings alongside wall damp, and growth discovered on arrival after time away.
- Rising damp
- Reads high at the base of the wall and falls with height. Stops at a consistent level, usually with salt crystals at the tide line.
- Penetrating damp
- A patch unrelated to floor level that darkens during and after rain and dries between.
- Condensation
- High surface moisture with a comparatively dry wall behind it. Worst in the coldest corners, behind furniture and around windows — and it occurs in buildings that are not leaking at all.
The pattern is the diagnosis. An inspector takes moisture readings at three heights plus humidity and surface temperature, because each mechanism leaves a different signature — and a thermal camera on its own does not see moisture, only temperature difference.
What it costs to put right in Plettenberg Bay
Drainage and clearance first, then timber repair. Ventilation routines for property left unoccupied.

Frequently asked questions
Why does the damp keep coming back in Plettenberg Bay?
Almost always because the water source was never found. Painting over mould or sealing the inside of a wall removes the evidence and leaves the cause running. In Plettenberg Bay the usual cause is year-round rainfall and coastal timber decay, and until that is dealt with the stain returns.
How much does a mould inspection cost in Plettenberg Bay?
Between about R1,800 and R4,500 for a diagnostic inspection with a written report, depending on the size of the property and access. Laboratory sampling, where it is genuinely warranted, adds R900 to R2,500 per sample — but for most homeowners who can already see the mould it adds cost without changing the remedy.
How do I know which type of damp I have?
By the pattern, not the appearance. Timber decay at deck bearers, window joinery and balustrade fixings alongside wall damp, and growth discovered on arrival after time away. An inspector takes moisture readings at floor, mid-wall and ceiling height, plus humidity and surface temperature, because rising, penetrating and condensation damp each produce a different signature.
What will it cost to fix?
Drainage and clearance first, then timber repair. Ventilation routines for property left unoccupied.
Is the mould in my home dangerous?
Indoor damp and mould are associated with respiratory symptoms, asthma exacerbation and allergic rhinitis, and the risk is higher for children, elderly occupants and anyone with asthma or a weakened immune system. It warrants prompt repair of the water source rather than alarm — and South Africa has no statutory indoor mould exposure limit, so be wary of anyone whose first recommendation is a laboratory test.
