How often should you reseal a driveway in Sydney?

A freshly sealed driveway looks fantastic — rich colour, water beading off the surface, oil and tyre marks wiping away instead of soaking in. The question we get asked most often is simple: how long does that last, and when do I need to do it again?

The short answer

For most Sydney driveways, a quality seal lasts three to seven years. That's a wide range because the honest answer depends on your surface, how much traffic it takes, how much sun it cops, and the type of sealer used. A sheltered, lightly used path might go well beyond seven years; a north-facing exposed-aggregate driveway with two cars on it daily will sit at the lower end.

What affects how long a seal lasts

• Sun and UV — Sydney's UV is harsh. North and west-facing driveways in full sun break down sealer faster than shaded ones.
• Traffic — Daily vehicle traffic, turning wheels and foot traffic all wear the surface film.
• Surface type — Smooth concrete holds a seal differently to porous exposed aggregate, pavers or natural stone.
• Sealer type — Penetrating sealers and topical "wet-look" sealers age differently. The right choice depends on your surface and the finish you want.
• Drainage and shade — Constant damp and shade encourage mould, which is the number-one reason a driveway looks "dirty again" quickly.
• Salt — Coastal and pool-side driveways face extra load from salt.

The signs it's time to reseal

• Water no longer beads — it soaks straight in.
• The colour looks dull, faded or patchy compared to when it was done.
• New stains (oil, leaf tannin, tyre marks) are starting to hold instead of wiping off.
• Mould or algae is returning faster than it used to.

If you're seeing two or more of these, the seal has worn through and the surface is no longer protected.

A rough guide by surface

• Plain & exposed-aggregate concrete: 3–7 years.
• Concrete, clay & brick pavers: 3–6 years.
• Sandstone & natural stone: 5–8 years, but pool-side and coastal surfaces sooner.
• Travertine: 3–5 years, sooner around salt pools.

Why resealing on time saves money

A driveway that's resealed on schedule is a quick clean-and-coat. A driveway left years past its seal has to be deep-restored first — lifting ground-in grime, treating mould that's taken hold, and sometimes addressing surface pitting that only happens once the protection is gone. Staying on a sensible cycle is almost always the cheaper path.
