Repair vs Replace Fence Cost in Adelaide (2026)
In Adelaide repairing or replacing a fence turns on whether the posts are sound, with the cheapest mainland labour making a new fence affordable.
Repair the existing fence
- Typical cost
- Replace individual palings $12 to $25 each fitted. Replace a rotted timber post $180 to $320. Steel post spur to a leaning post $120 to $200. Refix sagging rails $150 to $400. Replace a single Colorbond sheet $70 to $140.
- Expected remaining life
- A post spur or post replacement can buy 8 to 12 years if the rails and palings are sound. Paling swaps buy as long as the rest of the fence has left.
- Disruption and downtime
- Usually half a day. The boundary stays enclosed for most of it, which matters for dogs and small children, and there is no need for both neighbours to be home.
- Ongoing cost
- Timber benefits from staining or oiling every 3 to 5 years at roughly $12 to $22 per lineal metre, which materially extends paling life.
- Warranty
- Typically 12 months workmanship on a repair. Materials carry their own supplier terms.
- When it is false economy
- Replacing palings on a run where the posts have already rotted, or repairing a cracked fibro fence rather than dealing with it as asbestos.
Replace the fence
- Typical cost
- Timber paling $90 to $150 per lineal metre. Colorbond $95 to $170 per lineal metre. Rural wire and post $18 to $45 per lineal metre. Rendered masonry $450 to $900 per lineal metre. Add $60 to $120 per m² for licensed asbestos sheet removal.
- Expected remaining life
- Treated pine paling 12 to 20 years. Hardwood paling 20 to 30. Colorbond 20 to 30, less within a few kilometres of surf. Masonry 50 plus.
- Disruption and downtime
- One to three days for a typical suburban run. The boundary is open for at least part of it, so pets need containing and both neighbours need to know the dates.
- Ongoing cost
- Colorbond needs an occasional wash only. Timber needs staining every 3 to 5 years. Removing the maintenance cycle is a real part of the Colorbond case.
- Warranty
- Colorbond systems carry manufacturer warranties commonly 10 to 15 years against rust perforation depending on environment. Installer workmanship warranties usually run 1 to 7 years.
- When it is false economy
- Replacing a whole fence because six palings blew off in a storm, or replacing before serving a fencing notice and forfeiting the neighbour's legislated half share.
