The closer to open surf, the harder and faster it works: check [your suburb's AS 4312 corrosivity zone](https://saltcoast.com.au/coastal-exposure/) to see where you sit. Metal that lasts decades inland can show rust within a season or two on the coast. The mistake most people make is treating it as a cosmetic, paint-over job. Rust that's wire-brushed and painted without addressing what's underneath bleeds straight back through. Proper corrosion protection means diagnosing the cause, treating the metal correctly, and restoring a protective barrier that holds. Treated at the source ## How we treat rust and corrosion ### Diagnose We identify what's corroding, how far it's gone, and what's driving it. Surface tea-staining and structural corrosion are different problems with different fixes. ### Treat the metal Remove rust and tea-staining correctly without further damaging the surface, and address corrosion before it's sealed in. ### Re-protect Restore the protective barrier, with passivation for stainless, appropriate coatings or treatments for steel, so the metal is sealed against the next round of salt. ### Keep it protected Salt never stops arriving, so lasting protection means keeping it off. Regular washing and re-treatment on a schedule, not a one-off fix. What you can expect ## How we work with you ### Honest advice, not an upsell. We tell you what your home actually needs, and what it doesn't. If something can wait, we'll say so. We'd rather build a long relationship than win one oversized job. ### We treat the cause, not just the surface. Most coastal problems come back because they were patched, not fixed. We work out what's actually driving the damage (salt, moisture, corrosion) and deal with that, so the repair lasts. ### A proper look before any quote. We assess your property in person before we put a number on anything. It's free, there's no obligation, and it's the only honest way to quote coastal work, because every home is exposed differently. ### The coast is all we do. We're not generalists who also do beach houses. Coastal salt, corrosion and weather are our entire focus, which is why we catch the things others miss. Why it matters ## Built for the coast. Anyone can paint a wall or wash a house. The coast is different: salt gets into render, corrodes metal from the inside, and breaks down coatings from underneath, and it never stops. Treating coastal problems like inland ones is why so much work fails early. Salt Coast exists for exactly this. We diagnose before we treat, use methods and materials suited to coastal exposure, and build ongoing maintenance relationships rather than one-off jobs. That's how a coastal home stays sound instead of lurching from one repair to the next. [Maintenance Plans Keep your home ahead of the coast, not chasing it. Without a plan You wait for paint to peel, render to bubble, metal to rust, then react to damage that's been spreading for months. On a plan We catch it before it shows, while every fix is still small, cheap and quick, and you never lift a finger to manage it.

Salt air carries chloride that breaks down the protective layer on stainless, so even "stainless" steel tea-stains and spots near the surf. Marine-grade 316 holds up better than 304, but both need cleaning and re-protecting on the coast. [Does stainless steel rust on the WA coast? The honest answer](https://saltcoast.com.au/guides/does-stainless-steel-rust-coastal/) **Can coastal rust and tea-staining actually be removed?** In most cases yes. Surface tea-staining and rust are usually on the surface, so they clean off and the metal underneath is generally sound. The key is removing them without further damaging the surface, then restoring protection so they don't return. Deep, long-neglected corrosion is harder and sometimes can't be fully reversed, which is why treating it early matters. **Why does my stainless steel have orange staining?** That's tea-staining. Salt breaks down the protective layer on stainless near the coast, letting it corrode and stain even though it never would inland. It's removed and the surface re-passivated to restore its resistance. Marine-grade 316 holds up better than standard 304, but both need maintenance on the coast. [Does stainless steel rust on the WA coast? The honest answer](https://saltcoast.com.au/guides/does-stainless-steel-rust-coastal/) **Won't the rust just come back?** It will if the salt that caused it keeps accumulating. That's why proper corrosion protection isn't just treating the rust. It's re-protecting the metal and then keeping salt washed off so it can't restart. One-off treatment without ongoing protection is why people feel stuck re-treating the same items. [How to protect metal fixtures from coastal rust](https://saltcoast.com.au/guides/coastal-rust-prevention/) **Is rusting metal a structural problem?** It can become one. Surface tea-staining is cosmetic, but left untreated, corrosion can pit and weaken metal and cause fixtures and fastenings to fail. Catching and treating it early keeps a cosmetic issue from becoming a structural one. **Do you treat rust on fixtures and fittings, not just big items?** Yes. Fasteners, brackets, hinges, lighting and hardware often corrode first and bleed staining onto the surfaces around them. We treat and protect the small metal as well as balustrades, gates and structural steel. ![Cover of The Coastal Maintenance Guide](https://saltcoast.com.au/assets/guide-cover.webp) Free guide · 6 pages · PDF ### The Coastal Maintenance Guide Six pages on what salt, sun and driven rain actually do to a coastal home, what to look for on your own walls, and roughly how long you have before each one turns into a repair. *(This page carries an interactive enquiry form.
