Compare QuotesTypes of Damp and What Contractors Quote For
| Problem | Typical signs | Usual work |
|---|---|---|
| Rising damp | Tide marks, salts and flaking paint low on ground-floor walls | Diagnosis, DPC injection, salt-resistant replastering |
| Penetrating damp | Patches that appear or grow after rain, often near windows or high on walls | Repairing cracks, seals, parapets and gutters, then sealing the wall |
| Lateral damp | Damp on walls with soil, paving or a raised bed against the outside | Tanking, external membranes, lowering ground levels, drainage |
| Condensation and mould | Black spots in corners, behind cupboards and on cold outside walls | Mould treatment, ventilation, fixing cold spots |
| Wet areas | Damp around showers and baths, stains on ceilings below balconies | Membrane replacement, outlets, junctions and retiling |
| Ground water | Wet basements, water standing against foundations | French drains, basement and retaining wall waterproofing |
Different causes need different fixes. A quote that offers one treatment for every patch of damp, without explaining the cause, is worth questioning.

Ballpark figures, not quotations. Indicative 2026 ranges, rounded, from published South African damp-proofing, waterproofing and plastering price guides (Cape Town and Western Cape guides where available, national and Gauteng guides otherwise), checked October 2026. Per-metre prices are per linear metre of wall unless stated. Some include VAT and some do not, so confirm VAT on every quote. A site assessment and a written quote set the actual price.

Compare QuotesCape Town Conditions Damp Proofing Specialists Plan For
- Winter rainfall. Most of Cape Town's rain falls from May to August, often wind-driven. Penetrating damp usually shows up then.
- Shaded walls. South-facing and overshadowed walls get little winter sun and stay wet longer, which favours damp and mould.
- Coastal exposure. Salt air and wind-driven rain wear down paint, sealants and window seals faster near the sea.
- Older properties. Many older homes have no effective damp proof course, or one bridged by later paving, plaster or garden beds.
- Sandy, low-lying ground. Some low-lying areas have shallow ground water in winter, which affects basements and walls below ground.
Sectional Title and Rentals
In sectional-title schemes, exterior walls, roofs and many balconies are common property, so the body corporate or managing agent usually appoints the contractor. Tenants should report damp to the landlord in writing. This is general information, not legal advice.
Choosing Between Damp Proofing Contractors
- Compare the diagnosis, not only the price. Each quote should say what is causing the damp.
- Check what is included. Plaster removal, replastering, drying time, painting, rubble removal and VAT.
- Ask about guarantees in writing. What is covered, for how long and on what conditions.
- Get payment terms in writing. Deposit, balance and when each is due.
- Check the business. Contact details, photos of similar work and a reference or two.
Frequently Asked Questions
How does this service work?
You send one enquiry. Relevant independent damp proofing contractors covering your area contact you and quote. You compare and choose, or appoint nobody.
Does it cost anything?
No. Requesting quotes is free and there is no obligation. Your agreement is with the contractor you appoint.
Do you do the damp proofing yourselves?
No. This is a quote-comparison service. Independent damp proofing contractors inspect, quote and carry out the work.
How much does damp proofing cost in Cape Town?
As 2026 ballparks, chemical DPC injection is roughly R350 - R750 per linear metre, and a fully treated room of rising damp about R6,000 - R15,000. The cause and the area affected set the price.
Is the site inspection free?
It depends on the contractor. Some quote after a free site visit. Others charge an assessment fee, especially for a written report. Ask when you book.
Can I just paint over damp?
Not for long. Damp-proof paint can hide stains, but if the moisture source is not fixed the damp returns and the paint fails.
What should I include in my enquiry?
Suburb, property type, where the damp is, how long it has been there, whether it gets worse after rain, and photos.
Damp Proofing Cape Town is a free quote-comparison service. Damp is inspected, quoted and repaired by independent damp proofing contractors, and your agreement is with the contractor you appoint. Ask each one for a written, itemised quote, what is and is not included, guarantee terms and payment terms before paying anything.
