Waterfront air quietly corrodes render, timber, fixings and glass every day. Put your property's numbers in below and see the damage it's doing — in dollars and in hours — every year.
Your property
Not sure? A single-storey 4-bed is roughly 200–260m²; a large canal home 350–600m².
Proximity is the single biggest driver — it accounts for around 70% of salt exposure.

What we hand back
Based on your property, the cadence we'd recommend — quoted at your walkround:
This is an estimate, not a quote. It applies published Australian repair and maintenance costs to your property's size and exposure. Coastal homes sit in the highest atmospheric corrosivity zone under AS 4312, where metal corrodes 4–6× faster than inland, render spalls under salt-crystallisation pressure, and exteriors need repainting every 4–6 years instead of 7–10.
Figures draw on Standards Australia AS 4312 / ISO 9223 corrosivity data, ABIS/trade repaint costs ($5k–$20k), concrete spalling rates ($250–$900/m²) and re-render costs ($80–$150/m²). Your actual costs depend on construction, materials and current condition — the walkround is where we pin it down.
The mechanism
Every exposed surface on a coastal home breaks down in its own way. Left to react, each one hits a point where the damage sets in and the fix gets expensive. A regular salt rinse works the other way — it stops salt bonding in the first place.
Airborne salt is hygroscopic — it holds moisture against the glass and etches the surface into a permanent haze that no clean will lift once it sets.
Salt soaks into the pores, then crystallises as it dries — expanding up to 1,000% and cracking render off in sheets and fretting brick faces to powder.
Balustrades, screws, brackets and rails. On the surf coast (AS 4312 zone C5) metal corrodes 4–6× faster than the same fitting inland.
Pontoon edges, balconies and drives spall as chloride reaches the steel inside. Coastal concrete deteriorates 5–10× faster than inland.
Salt and UV chalk the paint, then rust streaks and staining follow. Coastal homes repaint every 4–6 years against 7–10 inland.
Salt and sun strip coatings and dry out timber, bringing forward recoats and board replacement across decks, pergolas and screens.
