- Salt air. Sea air corrodes reinforcement, causing spalling on balconies, decks and concrete walls.
- Holiday homes. Leaks in homes left empty for long periods go unnoticed and soften the ground or damage walls.
- Sloping and rocky sites. Homes on the cliffs and hillsides rely on retaining walls and good drainage.
Safety first. If cracks are opening quickly, doors or windows suddenly jam, or a wall, beam, balcony or retaining wall looks unstable, keep people and cars away and get a professional assessment promptly. Do not attempt structural repairs yourself.

Frequently Asked Questions
How much do foundation repairs cost in Hermanus?
Published guides put a foundation settlement repair at roughly R15,000 - R45,000 per job and rising damp, chemical DPC injection at roughly R450 - R1,400 per metre. The cause, ground conditions and access set the final price.
Why does concrete spall near the sea?
Salt in the air speeds up corrosion of the steel inside concrete. Rust expands and pushes the concrete off. The steel must be treated, not just plastered over.
Is a leaning retaining wall dangerous?
It can be. Keep people and cars away from the base and have it assessed promptly, especially after heavy rain.
Do I need Overstrand Municipality approval for foundation repairs?
Structural work such as underpinning may need approved plans. Your engineer or contractor can confirm before work starts.

No. This is a quote-comparison service. Independent specialists who work in Hermanus assess, quote and do the work.
