Overberg Storm-Grade Waterproofing

Waterproofing Hermanus — Built for the Hardest Winters in the Cape.

Hermanus, Onrus, Vermont and Sandbaai face the most aggressive winter storms in the Western Cape. Our heavy-duty systems are spec'd for sustained gale-force winds and horizontal rain.

— Why Hermanus Chooses Us

The waterproofing contractor Hermanus property owners trust.

Most Hermanus leak callouts trace back to lifted ridge caps and failed silicone window seals. We rebuild ridges with mechanical fixings and PU bedding, and replace every silicone bead with a 10-year polyurethane.

  • Storm-rated ridge cap and flashing systems
  • South-west facade hydrophobic treatments
  • Polyurethane window sealants — not silicone
  • Scheduled monthly Overberg site visits — predictable callout costs
  • 10-year warranty on full systems

Hermanus waterproofing — your questions answered.

Do you respond to emergency leaks in Hermanus during winter?

Yes — we run weekly Overberg trips through winter and can usually be on site within 3–5 working days. Critical emergencies are escalated.

Why does standard silicone fail so quickly in Hermanus?

Hermanus combines coastal salt, sustained wind, UV and significant thermal cycling. Standard acetic-cure silicone dries out and loses elasticity within 18–24 months. High-modulus polyurethane handles all four factors and lasts 10+ years.

Do you cover Onrus, Vermont, Sandbaai and Kleinmond?

Yes — the entire western Overberg from Kleinmond through to Stanford is core service area.

Is winter the right time to waterproof in Hermanus?

Emergency repairs yes — using cold-applied liquid systems. Full-scope projects are best scheduled between October and April when consistent dry days allow torch-on installation.
