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.
- Mature trees. Trees shade walls and roofs, and roots can damage drains and paving next to walls.
- Sloping plots. Split levels and retaining walls need waterproofing and drainage on the soil side.
- 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.

Frequently Asked Questions
How much does damp proofing cost in Constantia?
As 2026 ballparks, rising damp treatment with replastering is roughly R450 - R1,600 per linear metre, and retaining wall waterproofing about R250 - R550 per m². The cause and the area affected set the price.
Do large trees affect damp?
Heavy shade slows drying, and roots can damage drains and paving near walls. Both can add to damp problems.

It depends on the contractor. Some quote after a free site visit, others charge an assessment fee, especially for a written report.

No. Relevant contractors that cover your area respond, and numbers vary by job.
What should I send with my request?
Your suburb or estate, where the damp is, whether it changes with rain, and photos inside and outside.
