- Salt-laden wind. Beachfront homes and apartments see fast corrosion of steel and concrete.
- Windblown sand. Sand settles when washed out by leaks.
- Balconies and basements. Joints and below-ground walls let water in when they fail.
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 Big Bay?
Published guides put a foundation settlement repair at roughly R15,000 - R45,000 per job and french drain at roughly R450 - R950 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.
Why is my floor slab cracking or sinking?
In sandy ground, leaking pipes or stormwater can wash sand from under slabs, or the fill was poorly compacted. Find and fix any leak before repairing.
Do I need City of Cape Town approval for foundation repairs?
Structural work such as underpinning may need approved plans. Your engineer or contractor can confirm before work starts.
Do you do the repairs yourselves?
No. This is a quote-comparison service. Independent specialists who work in Big Bay assess, quote and do the work.
