Repair vs Replace Driveway Cost in Perth (2026)
In Perth repairing or replacing a driveway turns on whether the base has failed, with sandy ground washing out under an undrained slab.
Repair or resurface
- Typical cost
- Crack sealing $15 to $30 per lineal metre. Concrete grinding to remove a trip lip $250 to $600. Asphalt pothole patching $150 to $400 each. Hot mix overlay $45 to $75 per m². Concrete resurfacing overlay $55 to $95 per m². Paver relay $50 to $90 per m².
- Expected remaining life
- Crack sealing buys 3 to 7 years. An asphalt overlay buys 8 to 15 years on a sound base. A concrete overlay buys 8 to 12. All of them are capped by the base beneath.
- Disruption and downtime
- Crack sealing and patching is a few hours with the driveway usable the next day. An overlay is one to two days plus 24 to 72 hours before vehicles.
- Ongoing cost
- Asphalt benefits from resealing every 5 to 8 years at roughly $8 to $15 per m². Concrete benefits from resealing every 3 to 5 years at $10 to $20 per m².
- Warranty
- Typically 12 months on patching, and 2 to 5 years on a professionally applied overlay from an established contractor.
- When it is false economy
- Overlaying a driveway that is stepping, rocking or ponding. The new surface will crack along exactly the same lines within one or two wet seasons because nothing beneath it changed.
Full replacement
- Typical cost
- Plain concrete $110 to $160 per m² including excavation and disposal. Exposed aggregate $140 to $220 per m². Asphalt $85 to $135 per m². Pavers $130 to $250 per m². Add $1,000 to $3,500 for a new crossover, drainage or retaining.
- Expected remaining life
- Concrete 30 to 50 years. Asphalt 15 to 25 with resealing. Pavers 25 to 40 with occasional relevelling. All assume a properly compacted base.
- Disruption and downtime
- Three to seven days including demolition, base preparation, pouring and curing. Vehicles stay off concrete for at least seven days and heavy vehicles for 28.
- Ongoing cost
- Concrete needs sealing every 3 to 5 years to resist oil staining. Asphalt needs resealing every 5 to 8. Pavers need occasional joint sand top up and weed control.
- Warranty
- Structural work above state thresholds carries statutory building warranty, commonly six years. Reputable concreters typically warrant workmanship for 5 to 10 years excluding normal shrinkage cracking at control joints.
- When it is false economy
- Ripping out a fifteen year old concrete driveway because of hairline shrinkage cracks at the control joints, which are exactly what those joints are for.
What a repair vs replace driveway costs in Perth
Deciding to repair or replace a driveway in Perth turns on whether the fault is in the surface or the base below, since patching, crack-filling or resurfacing a driveway with a sound base is far cheaper than a full replacement, but once the base has washed out or failed and the slab is cracked and subsiding, it must be dug out and re-laid. A surface crack or worn finish is a repair, while a sunken or undermined slab is a replacement, so the state of the base leads the decision.
Perth's sandy soils are the factor, because loose sand can wash or erode out from under a driveway where drainage concentrates water, undermining the slab so it cracks and sinks, which points to replacement on a properly compacted base. The hot, dry Mediterranean climate is otherwise easy on a surface, though a reticulation leak can soften the ground under a slab. A driveway behind a double-brick home on a sandy block is checked at the base, not just the surface. A shared driveway is a common-property matter, and a crossover on the council verge needs an approved contractor. The isolation of the WA market is no issue for a local concreter. Resurfacing or patching is paving and concreting work by a driveway contractor or concreter rather than a licensed building trade in Western Australia.
Repairing or replacing a driveway is paving and concreting work by a driveway contractor or concreter rather than a licensed building trade, so no building licence applies, though a crossover on the council verge needs a council-approved contractor and a retaining element needs a licensed builder, in Western Australia under WA Building Services for any building side. For a Perth home, the clearest way to decide repair against replace is by whether the base has failed, with sandy ground the thing that washes out under a slab.
