UV bleaches the timber grey and breaks down its surface; the wet-dry cycle of coastal weather makes boards expand, contract, cup and split; and salt dries the timber out and works into the grain. An unsealed or long-neglected deck doesn't just look bad, the timber itself degrades, and once boards have split and silvered badly, restoration is harder and some boards may be past saving. Brought back to life ## How we restore and seal a deck ### Assess the timber Check the deck's condition, how far the weathering has gone, whether boards need replacing, and what finish suits the timber and use. ### Clean and prepare Remove the greyed surface layer, grime, salt and old failed finish, and sand back where the timber needs it, the prep that decides how well the new finish takes and lasts. ### Repair Address splintered, cupped or damaged boards and fixings before finishing. ### Seal or oil Apply the right finish for the deck, enough coats, worked into the timber for real protection rather than a thin surface film. See our [deck oiling vs staining guide](https://saltcoast.com.au/guides/deck-oiling-vs-staining/) for finish options. 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.

The grey is a weathered surface layer; cleaning and sanding it back usually reveals sound timber underneath, which is then restored and sealed. Badly split or rotted boards may need replacing, but a deck that just looks greyed and tired is normally very restorable. **What's the difference between oiling, staining and sealing a deck?** They protect and look different: oils penetrate and nourish the timber with a natural look and are easy to re-coat; stains add colour and some protection; film-forming sealers and coatings sit on top for a harder wearing finish but can peel. The right choice depends on your timber, the look you want and how the deck is used. [Deck oiling, staining or sealing: the differences and which to choose](https://saltcoast.com.au/guides/deck-oiling-vs-staining/) **How often does a coastal deck need re-oiling or re-sealing?** More often than an inland deck, because the deck is flat, fully sun-exposed, walked on and hit by salt. The exact interval depends on the finish, the timber and the exposure, but coastal decks generally need refreshing regularly, and re-coating before the finish fails is far easier than restoring a deck that has weathered back to grey. **Why does my deck go grey and rough?** UV bleaches and breaks down the timber surface, turning it grey, while the coastal wet-dry cycle and salt dry the timber out and make boards cup, split and splinter. An unsealed or long-unmaintained deck weathers this way; restoring and sealing it brings the colour and smoothness back and protects it from doing it again. **Do you replace damaged deck boards too?** Yes, where boards are split, rotted or beyond restoring, they are replaced as part of the restoration. The aim is a sound, smooth, properly finished deck, so anything that cannot be brought back is dealt with rather than just coated over. ![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.
