Restumping in Coburg
Coburg is one of the better suburbs in Melbourne to have to restump, and the reason is boring but valuable: the blocks are wide. Genuine side access means machine-dug stump holes and machine-removed spoil, which strips days of hand labour out of the job and is why Coburg quotes come in below equivalent inner-west ones.
Coburg housing — what we are usually dealing with
Coburg's stock is dominated by interwar and post-war housing — California bungalows through the older streets, and a large body of 1940s to 1960s weatherboard and timber-floored homes further out, including a significant amount of former Housing Commission stock. Post-war homes typically used early concrete stumps rather than timber, which changes the failure mode entirely. Concrete stumps do not rot; they fail by settling into inadequate footings, or by cracking where the reinforcement inside has corroded and expanded. So a Coburg subfloor inspection is looking for different evidence than a Yarraville one — spalling and rust staining down the stump face, not soft timber at ground level.
The ground under Coburg
Coburg sits on the northern clay plains around the Merri Creek corridor. It is moderately reactive clay: enough seasonal movement to matter, particularly on properties backing onto the creek reserve or with mature eucalypts nearby drawing moisture out of the ground on one side of the house. Original stump footings from the interwar and post-war period were shallow, which is precisely the depth range where that seasonal movement is strongest.
What this means for your job
Because access is good, the economics here favour doing the whole house rather than staging it. Mobilising a machine and crew twice for two half-jobs costs more than doing it once. The other Coburg-specific point is tree management: if a large eucalypt on or near the boundary is driving seasonal movement, new footings need to be taken deeper than standard, or the movement will simply resume under brand new stumps. Many of these trees are protected under Merri-bek's local law, so removal is often not an option and the footing design has to accommodate them.
What we see in Coburg homes
- Rust staining or flaking concrete on the face of existing concrete stumps
- A whole corner of the house that has settled evenly rather than a localised dip
- Movement concentrated on the side of the house nearest a large tree
- Cracks in a brick chimney breast pulling away from the timber wall frame
Restumping costs in Coburg
$11,000 – $18,000 for a full restumpCoburg is one of the more affordable inner-Melbourne suburbs to restump, purely because machine access is usually possible. Where deeper footings are required to get below tree-influenced clay movement, add roughly 15 to 25 per cent.
Indicative range only, based on typical jobs in this area. Access, soil conditions and the extent of movement change the number — a fixed price follows an on-site inspection.
The right service for Coburg
Coburg homes of this era have suspended timber floors on individual stumps, so restumping and reblocking is the service that applies — replacing failed stumps and re-levelling the floors above them. Read what the full job involves, including permits and the lifting process, on our restumping page.
Restumping in Coburg — your questions
My Coburg house has concrete stumps — can they still fail?
Yes, just differently. Concrete stumps do not rot, but they fail in two other ways. The first is settlement: the stump itself is sound but the footing under it was shallow or poorly compacted, so the whole thing sinks. The second is concrete cancer — the steel reinforcement inside corrodes, expands, and splits the stump from within, which shows as rust staining and flaking down the face. Early post-war concrete stumps in Coburg are now 60 to 80 years old and both failure modes are common.
Does the big gum tree next door mean I cannot restump?
No, but it changes the footing design. Large eucalypts draw substantial moisture from clay soil, shrinking the ground on that side of the house through summer and letting it swell back in winter — which moves shallow footings with it. The answer is not usually to remove the tree, which in Merri-bek is frequently protected under local law anyway. It is to take the new footings deeper, past the zone of seasonal moisture change, so the tree's influence no longer reaches them. Say the tree exists at quoting stage so the depth is priced in.
Why is restumping cheaper in Coburg than in Yarraville?
Access. Coburg's blocks are typically wide enough to get a mini excavator down the side of the house, so stump holes are machine-dug and spoil is machine-removed. In the inner west's single-fronted cottages, every hole is hand-dug and every barrow of soil comes out through the hallway. That is several extra days of labour on the same number of stumps, and it is the main reason for a price gap of several thousand dollars on otherwise comparable houses.
