Pinelands is a low-lying garden suburb on the flats near the Black River, with a lot of 1920s and 1930s housing stock. The flat, damp-prone ground and mature trees mean blocked drainage, rising damp and roof leaks show up often, and the older homes benefit from a proper diagnosis before any treatment.
Damp in a wall is a symptom, not the disease. The fix that lasts is the one that treats the actual cause, and that starts with a proper diagnosis, not a guess. DryCape matches Pinelands homeowners with one vetted local specialist, not a queue of cold callers, for a free, no-obligation quote.
Damp proofing covers the diagnosis and treatment of unwanted moisture in walls. The three causes a specialist will rule in or out are rising damp (groundwater wicking up from the foundation), penetrating damp (rain driven through a wall or a failed seal) and lateral damp (moisture pushing through a wall that retains soil, common on Cape Town's slopes).
Treatment depends entirely on the cause. Rising damp is treated with a chemical damp-proof course, injecting a silicone cream or fluid into the base of the wall to form a new water barrier, followed by removing the salt-contaminated plaster and re-plastering with a breathable, salt-resistant render. Penetrating damp is treated by fixing the external defect and sealing the wall.
The single biggest reason damp 'comes back' is treating the symptom (re-painting over it) without fixing the cause. A reputable damp specialist uses a moisture meter, checks ground levels and drainage, and explains which type of damp you actually have before quoting.
Damp proofing is usually quoted per linear metre of wall treated, plus the re-plastering. Rising damp is the most involved and sits at the top of the range. Use these indicative Cape Town ranges to set expectations, your Pinelands specialist quotes on the actual job after seeing it.

General 2026 guidance, not a quote. More detail in our Cape Town cost guides.
Rising damp shows a tide-mark up to about a metre with salt deposits and is worst at skirting height. Condensation forms on cold surfaces (windows, behind furniture, in corners), is often higher up, and is usually paired with mould rather than salts. A specialist's moisture meter settles it quickly, and it matters, because the two have completely different fixes.
Reputable specialists guarantee a chemical DPC for 10 to 20 years, but the guarantee only holds if the re-plastering and salt removal were done properly and the external causes (high ground levels, leaking gutters) were corrected. Always get the guarantee in writing and keep the invoice.
Because paint is a cosmetic cover, not a cure. If the underlying rising or penetrating damp isn't treated, moisture and salts push straight back through the new paint within a season. The lasting fix treats the cause and uses a breathable, salt-resistant plaster, not another tin of paint.
