A concrete driveway needs a wash every 3 to 6 months and a fresh seal every 3 to 5 years to hold up well against Auckland's rain, UV exposure and moss.

Beyond that, a properly installed driveway needs very little upkeep, and most of what it does need is cheap and easy to stay on top of if you catch issues early.

Maintenance at a glance

Regular cleaning

Wash every 3 to 6 months to remove dirt, moss, algae and grime before it stains or becomes slippery, particularly in shaded or damp corners.

When to reseal

Reseal every 3 to 5 years as a general rule, or once water stops beading and stains start lingering longer than they used to.

Best time to seal

Spring or summer, since warmer temperatures and lower humidity give the sealer better adhesion and a faster, more even cure.

Dealing with cracks early

A hairline crack left alone lets water in and the damage spreads. Routing, sealing or patching early is far cheaper than a full repair later.

What sealing protects

Sealer protects against oil and rust stains, moss and algae growth, UV fading, and slows water penetration into the slab.

What sealing actually protects against

Sealer protects the concrete from oil and rust stains, moss and algae growth, and UV fading on coloured or stamped finishes. It also slows water penetration into the slab itself, which matters in Auckland's climate where the ground underneath stays damp for long stretches through winter.

FAQ

How often should I reseal my concrete driveway?

Reseal every 3 to 5 years as a general guide, though the clearest sign is when water stops beading on the surface or stains start lingering longer than usual.

How often should I wash my concrete driveway?

Wash it every 3 to 6 months to remove dirt, moss and algae before they stain the surface or make it slippery, especially in shaded or damp areas.

What is the best time of year to seal a concrete driveway?

Spring or summer is best, since warmer temperatures and lower humidity help the sealer adhere properly and cure evenly. Sealing during a wet or cold spell can affect how well it bonds.

Do I need to seal a concrete driveway at all?

It's strongly recommended in Auckland's climate. Constant rain, strong UV and moss-prone conditions wear down an unsealed surface faster, and sealing protects against staining, fading and moisture getting into the slab.

Should I fix a small crack in my driveway myself?

Small hairline cracks can be sealed or patched to stop water getting in, but it's worth getting them assessed first. What looks like a small cosmetic crack can sometimes be an early sign of base movement.
