Some contractors add a travel charge outside their base area, so ask whether it is included.
Common Damp Problems in Southern Suburbs

Local Conditions Contractors Should Plan For
- Higher rainfall. Suburbs close to Table Mountain get much more rain than the Cape Town average, so walls stay wet for longer.
- Shade. Mountain shadow and large trees keep some walls and rooms cold in winter, which slows drying and favours mould.
- Older houses. Many were built without an effective DPC, or have one bridged by later paving, soil or plaster.
- Heritage buildings. Buildings older than 60 years may need heritage approval for some external work. Lime-plastered walls should not be sealed with cement plaster or impermeable paint.
What to Send for an Accurate Quote
- Suburb, estate or building name.
- Where the damp shows, how high and how big.
- Whether it gets worse after rain.
- House, townhouse, flat or commercial property.
- Photos inside and outside the affected wall.

Why do the Southern Suburbs get more damp?
Suburbs close to Table Mountain, such as Newlands and Constantia, get much more rain than the city average, and mountain shade keeps walls cold and wet.
