- Manufacturer-approved applicators (Index, Derbigum, Sika, Plascon)
- Free no-obligation roof inspection before quoting
From R220/m²
2026 indicative ZAR pricing. Torch-on R220-R380/m², liquid acrylic R150-R260/m², polyurethane R350-R550/m². Final quote on-site.
Damp Treatment
Damp Proofing
Compare quotes from vetted Durbanville damp specialists — rising damp, penetrating damp, lateral damp and condensation diagnosis and treatment for Northern Suburbs homes.
- Compare diagnosis-led quotes from contractors who survey before injecting — no guesswork chemical treatment
- Listed specialists distinguish rising damp from penetrating and lateral damp (different cures, different prices)
- Vetted contractors typically offer free moisture-meter surveys and written reports
From R650/linear m
2026 indicative ZAR pricing from Durbanville specialists. Chemical DPC injection R650-R1,100 per linear metre. Salt-neutraliser plus breathable render R450-R900/m². Penetrating damp wall treatment R350-R650/m². Free survey first — final quote always on-site after the moisture reading.
Rising Damp Treatment
Vetted Durbanville damp specialists inject chemical DPC and apply salt-resistant render to stop rising damp in older Northern Suburbs homes.
- Permanent chemical barrier — modern silane/siloxane creams carry a 20+ year manufacturer guarantee against re-wicking
- Stops the salt bloom and bubbling paint that no amount of repainting will fix
- Protects skirtings, timber floors and built-in cupboards from rot and borer attack
From R450/m linear
DPC chemical injection runs R450–R900 per linear metre of wall treated, depending on wall thickness (single skin vs 220mm double skin vs 340mm cavity) and access. Salt-resistant re-rendering is quoted separately at R220–R380/m² and is usually the larger line item. A typical 8m semi-detached wall (injection + render to 1.2m) lands at R8,500–R14,000. Insist on a written manufacturer guarantee — anything under R400/m linear is almost always uncertified product.

- Same-day or next-day callouts from Durbanville-based crews during winter storm season

Below-Grade Waterproofing
Basement & Foundation Waterproofing
Vetted Durbanville specialists for below-grade waterproofing — cementitious tanking, crystalline integral systems, bentonite membranes and french drains for slope-side homes.
- Negative-side AND positive-side options — interior tanking when excavation is impossible
- Crystalline systems (Penetron, Xypex, Krystol) that self-seal cracks up to 0.4mm
- French drain installation to relieve hydrostatic pressure on slope-side homes

- Slows tile chalking and concrete dusting from Cape Town summer UV
- Reflective lighter colours can drop loft temperatures 4-7°C

Ancillary Services
Gutter Repair & Cleaning
Compare vetted Durbanville gutter specialists for pre-winter cleaning, aluminium repair and full replacement before the May rains hit.
- Pre-winter clean-and-flush stops the overflow that causes damp patches on internal walls and rotted fascia boards
- Aluminium replacement gutters carry a 15–20 year lifespan vs 5–8 years for legacy PVC seamless gutters
- Local contractors know which Durbanville suburbs (Sonstraal, Eversdal, Pinehurst) have the worst oak-leaf load and price accordingly
From R450 (cleaning, single-storey ≤15m run)
Cleaning: R450–R900 single-storey, R900–R1,500 double-storey or large homes (Welgemoed, Plattekloof). Spot repairs: R180–R400 per linear metre depending on access and joint count. Full aluminium seamless replacement: R250–R550 per linear metre installed (includes brackets, outlets, downpipes — pricing varies with profile, colour and roof access). Get 2–3 quotes before committing — gutter pricing varies more than any other waterproofing trade.
Roof Cleaning
Pressure-wash moss, lichen and algae from roof tiles, plus fungicide treatment and gutter clear-out — the essential prep step before any waterproofing or coating job.
- Mandatory prep step — manufacturer roof-coating warranties (Plascon, Dulux, Earthcote) are void if the substrate isn't professionally cleaned and treated first
- Soft-wash and biocide treatment kills moss and lichen at the root, preventing regrowth for 3–5 years versus 6 months for a pressure-wash alone
- Local contractors know which Northern Suburbs roofs (Welgemoed oak-shade tile roofs, Bellville flat IBR) need which approach — high-pressure damages tile glaze, low-pressure won't shift heavy lichen on metal
From R3,500 (single-storey tile roof, ≤120m²)
Tile soft-wash + biocide: R30–R55/m² depending on moss load and access. IBR or metal pressure clean: R25–R45/m². Bundled clean + roof coating: typically R85–R140/m² combined (saves vs separate quotes). Double-storey homes (Welgemoed, Plattekloof) add 20–30% for scaffolding and harness setup. Always get the cleaning + coating quoted together if you're planning to coat — it's substantially cheaper than booking the two trades separately.
Interior Wet Areas
Wall & Shower Waterproofing
Vetted Durbanville specialists for leaking showers, baths and splashbacks. Tanking slurry, liquid membrane and external wall sealing — flood-tested with a 10-year guarantee.
- Flood-tested every job — 24-hour standing-water test before re-tiling
- Body-corporate-ready written reports with photos for trustees and managing agents
- Non-invasive options first — penetrating sealers and clear epoxy grout overlays where tile-strip is avoidable
From R3,500 per shower
2026 indicative ZAR pricing. Shower re-waterproofing without retiling R3,500-R7,500 per shower. Full strip + tank + retile R8,000-R18,000 per shower depending on tile choice and box size. External wall sealing R85-R180/m² (penetrating silane vs pigmented elastomeric). Body-corporate jobs quoted per stack — discounts on multi-unit blocks.
