Repair vs Replace Driveway Cost in Hobart (2026)
In Hobart repairing or replacing a driveway turns on whether the base has failed, with sloping sites and frost the factors.
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 Hobart
Whether to repair or replace a driveway in Hobart turns on whether the problem is in the surface or the base beneath, because crack-filling, patching or resurfacing a driveway with a sound base is far cheaper than a full replacement, but once the base has 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 slipped slab is a replacement, so the state of the base leads the decision.
Hobart's sloping sites are the main factor, because a steep driveway on a hillside is prone to the base slipping or water scouring under it, and runoff concentrates on the fall, so a slab that has moved on a slope often needs replacing with proper drainage and a sound base. The cold, frosty winters work water in a crack with the freeze and thaw, widening it over time. A colonial or weatherboard home may have an old crossover worth upgrading. A shared driveway is a common-property matter, and a crossover on the verge needs an approved contractor. Island freight is no issue for local concrete. Resurfacing or patching is paving and concreting work by a driveway contractor or concreter rather than a licensed building trade in Tasmania.
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 verge needs a council-approved contractor and a retaining element needs a licensed builder, in Tasmania under the state regulator. For a Hobart home, the clearest way to decide repair against replace is by whether the base has failed, with sloping sites and frost the factors.
