House Restumping & Reblocking in Coburg

Restumping and reblocking are two commonly used names for replacing the stumps that support a raised floor. The work may involve a few defective supports or a larger part of the house, depending on the condition of the existing stump system.

Replacing failed or deteriorated stumps

We consider the visible condition of existing stumps, how they meet the bearers, and whether there are signs of movement, deterioration or unsuitable support. Replacement footings and stumps must suit the structural requirements and the ground conditions established for the job.

Partial restumping or a full replacement?

Replacing selected stumps may be suitable where defects are localised and the remaining supports are in acceptable condition. If deterioration extends across much of the support system, broader restumping may be appropriate. The number of stumps alone does not answer the question; their condition, load paths and the practicality of retaining existing supports all matter. Our partial versus full restumping guide explains this choice in detail.

Levelling when the stumps are still sound

A floor can slope even when its stumps remain serviceable. In some cases the issue involves packing or floor framing, and house relevelling may be considered instead of a full restump. We inspect the support arrangement before discussing a method.

Coburg has an established mix of bungalows, weatherboard houses, brick homes and more recent developments. Some older houses have suspended timber floors supported by stumps; others have different foundations, or a combination after extensions. The age and appearance of a building cannot confirm its foundation type.

When an extension meets the original house

A common question in renovated homes is why one floor area has changed level while an adjoining room has not. The original building may have stump-supported flooring while a later kitchen, living area or extension uses different footings or a slab. We need to establish which part is moving before treating the problem as a restumping job. Where the affected area involves a different foundation, the repair may need another type of assessment.

Access can change the proposed work

Established Coburg properties can have fences, additions, garden structures or limited clearance that affect how workers reach the subfloor. Some jobs can be approached from an existing access opening, while others may require a carefully planned alternative. The accessibility of each affected area helps determine both the method and the quote.

Previous work matters

If a house has already been partially restumped, tell us when the work was done and which areas were involved. Mixed stump materials or support heights may affect how the remaining sections can be repaired and relevelled. Copies of old permits, plans or engineering documents are useful when available, but you can still enquire without them.

These repairs address different problems. We don’t recommend replacing stumps simply because floors slope, or underpinning a footing simply because a crack is visible.

Once the scope, required plans and approvals have been established, the work typically involves four stages:

1. Plan and prepare. Confirm the affected stumps, access arrangements, temporary supports and any required permits or engineering details.
2. Safely support the structure. Provide suitable temporary support and controlled lifting where required before disturbing the existing stumps.
3. Install replacement supports. Replace the specified stumps and footings in accordance with the relevant design and site requirements.
4. Re-establish and check floor support. Adjust support and levelling as agreed, and complete the inspections and associated work required for the particular project.

How long this takes and whether the household can remain in the property depend on access, the number of supports, lifting requirements, permits and whether rooms need to be opened up. We discuss disruption after the work has been assessed, rather than promising a standard timeframe.

House restumping in Coburg generally needs building-permit consideration. Merri-bek City Council lists re-stumping among works for which a building permit is typically required, subject to the applicable building regulations and any exemptions. The required documentation depends on the proposed work and must be confirmed with the relevant building surveyor.

Some Coburg properties also fall within heritage overlays or other planning controls. These do not mean every internal or underfloor repair automatically needs a planning permit. However, where work changes a building’s external appearance or otherwise triggers a planning control, a separate planning permit may be relevant. Check Merri-bek’s planning-permit guidance for the particular address and scope.

In Victoria, the homeowner chooses and appoints the building surveyor for work under a domestic building contract; the builder cannot appoint a private building surveyor on the owner’s behalf. See the Building and Plumbing Commission’s guidance.

For eligible domestic building contracts signed from 1 July 2026, Victoria’s Home Warranty scheme generally applies to eligible work valued at more than $20,000, subject to exclusions. This statutory cover is separate from our 15-year guarantee on qualifying work.
