Caringbah has plenty of knockdown-rebuild and duplex activity, and fencing follows the builders. Every new duplex pair needs boundary fencing, a dividing fence between the two homes, and often side gates and a front fence to finish the job. Granny flats are common here too, and they frequently trigger a fence upgrade so the secondary dwelling has its own defined yard.
The fencing contractors we work with handle both ends of the Caringbah market: crisp new Colorbond packages on rebuilt blocks, and like-for-like timber replacements on the original streets where a 1970s paling fence has finally let go.
Common fence jobs in Caringbah
- Dividing fences between new duplex pairs, usually Colorbond or lapped timber
- Full boundary packages on knockdown-rebuild blocks
- Fencing off a granny flat yard from the main house
- Pool fencing for new and existing backyard pools
What fencing costs in Caringbah
Guide pricing only: Colorbond and timber paling typically run from around $80 to $190 per metre installed, with Sydney jobs often toward the top of that range. Gates and sloped sections are extra. Multi-boundary duplex jobs are usually priced as one package. The fencing cost guide explains what moves the price, and a quote on the block settles it.
Where a fence divides two properties, NSW law generally expects both owners to share the cost of a sufficient dividing fence. Builders and neighbours handle this differently on rebuild sites, so get the arrangement in writing. General information only, not legal advice.
Frequently asked questions
What fence goes between the two homes in a duplex?
Most Caringbah duplexes use 1.8 metre Colorbond or lapped-and-capped timber between the dwellings for privacy. The choice is often made by the builder, but owners can upgrade at build time for less than a retrofit.
Do I need a fence around a granny flat?
Not by law, but a separate fenced yard helps with privacy and is usually expected by tenants. A simple paling or Colorbond divider with a gate is the common setup.
My neighbour is rebuilding. Who pays for the new boundary fence?
If the old fence was sufficient and the build damaged or removed it, the builder usually reinstates it. If it was already failing, a half-share is the common outcome. Agree before demolition starts.
