Leaking roof? Rising damp? Water damage spreading through your property?
We fix moisture problems permanently. This coastal town's combination of salt-laden Atlantic winds, seasonal whale-watching rains, and dramatic cliff-side exposure creates relentless moisture challenges. We use locally manufactured Sealtek products designed for these exact conditions.
Every project includes a 5-year written guarantee, professional assessment, and installation by a Sealtek Accredited Applicator.

Hermanus roofs face relentless assault from salt spray, coastal winds, and heavy winter rainfall. Metal roofs corrode faster here than almost anywhere in the Western Cape. Tile roofs suffer from wind-driven rain forcing moisture beneath the surface. By the time you notice ceiling stains, structural damage has already begun.
Our roof waterproofing works on all roof types: concrete tiles, metal sheeting, IBR, corrugated iron, chromadek, and asbestos encapsulation. Seamless liquid membranes eliminate failure points while withstanding the coastal environment.
Damp walls create more than unsightly marks. Left untreated, rising damp destroys plaster, damages timber, and creates ideal conditions for mould growth that affects your family’s health.
Our damp proofing solutions treat the cause, not just the symptoms. We identify moisture entry points through professional diagnosis, then apply appropriate Sealtek damp barriers to stop water penetration permanently.
A leaking roof needs proper diagnosis, not quick patches that fail within months.
Our leak repair process identifies root causes: failed flashings, corroded fasteners, cracked tiles, or deteriorated membranes. We implement permanent repairs using Sealtek’s liquid-applied systems that bond seamlessly to existing surfaces.
Stop paying for repeated temporary fixes.
Hermanus properties built into the cliff faces and slopes face significant groundwater pressure against basement walls. The combination of winter rainfall and natural springs forces moisture through concrete, even through hairline cracks invisible to the eye.
Our basement waterproofing systems create continuous barriers that withstand water pressure while allowing trapped moisture to escape. We address both external water infiltration and internal condensation from coastal humidity.
Balconies take constant punishment from UV radiation, temperature changes, and rain. In Hermanus, add salt spray and coastal wind to that mix. Over time, this produces cracking, joint separation, and grout deterioration that allows water into the slab below.
Our liquid membrane systems create seamless protection that moves with your building’s natural expansion and contraction. We waterproof over existing tiles where possible, avoiding costly removal and replacement.
Hermanus’s dramatic coastal setting creates distinct waterproofing challenges across different areas:
Cliff-side properties (Eastcliff, Westcliff, Kwaaiwater): Direct ocean exposure means constant salt spray and wind-driven moisture
Fernkloof area: Mountain slope properties face heavy rainfall runoff combined with fynbos humidity
Onrus and Vermont: Lagoon-adjacent properties deal with high water tables and coastal humidity
Sandbaai and Voëlklip: Beachfront exposure demands systems built for harsh marine environments
