Why the order matters

Geelong is full of older homes being renovated rather than knocked down: period weatherboards in Geelong West and Newtown, post-war homes in Belmont and Bell Park, and beach houses across the Bellarine. Most of them are still on stumps, and many of those stumps are at or past the end of their life.

Reblocking lifts, re-levels and re-supports the floor. That's exactly what you want before a renovation and exactly what you don't want after one. When a house is jacked back to level, the frame moves. Tiles, stone benchtops, new plaster and freshly sanded floorboards don't enjoy that movement. The result is cracked grout, doors that need re-hanging and cabinetry that no longer sits square.

The simple rule: sort out what's under the floor before you spend money on what's on top of it.

Step 1: Find out what's underneath

Before you finalise plans, get a stump and subfloor inspection. Level readings across the house show where and how far the floor has moved, and a look underneath shows whether the stumps, the packing or the framing is responsible. The answer shapes your budget:

Nothing needed yet. The stumps are sound and you can renovate with confidence.
House re-levelling. The stumps are fine but the packing has failed. This is a smaller job.
A partial reblock. One part of the house has failed, often the side facing the weather or an area near a leaking downpipe.
A full reblock. The original stumps are failing throughout, common in pre-1970s homes still on red gum or early concrete.

Our Stump & Subfloor Inspections service covers this. If you've already had a builder's report that mentions "floor out of level", it's worth getting the detail before you sign a renovation contract.

Step 2: Plan reblocking around the trades

Reblocking is noisy, dusty work done from under the house, but it doesn't need the kitchen or bathroom stripped out. The usual order looks like this:

Inspection and quote for the reblock, plus any bearer or joist repairs.
Building permit for the reblock, or folded into the renovation permit if the job is bigger. Our page on whether you need a permit to reblock a house in Victoria explains how that works.
Reblock and re-level the house.
Let it settle. Some minor movement after re-levelling is normal, so a short gap before plastering and tiling is sensible.
Renovation trades start on a level, well-supported floor.

If your renovation includes new plumbing under the floor, talk to your plumber about timing. It's often easier for them to run new pipes while the subfloor is already open and accessible.

Step 3: Fix the framing at the same time

Reblocking is the best opportunity you'll get to fix the floor framing. Older Geelong homes often have bearers with rot where they sat on failing stumps, joists notched by past plumbers or electricians, or framing weakened where a wall was removed decades ago. Repairs at this stage are straightforward because the house is already supported and accessible. Once new floors are down, the same repairs mean lifting them.

Our Subfloor & Bearer Repairs service handles this alongside the reblock, so you aren't paying for the house to be lifted twice.

Extensions: joining old to new

If you're adding a room, a deck or a second living area, the new section will sit on new footings designed to current standards. The old house needs to be level and stable before the two are joined, or the junction becomes the place where cracks open.

Things to raise with your builder and with us early:

Floor heights. The new floor should meet the existing floor level, which is only possible if the existing floor is level to begin with.
Different foundations. New concrete or steel stumps on engineered footings move differently from a century-old house on red gum. Reblocking the old part reduces that difference.
Ground conditions. Clay in the northern suburbs, the slopes of Highton and the sandy ground on the Bellarine all affect footing design for both the old and new sections.

Polished floorboards: a special case

Many owners renovating a Geelong West or Newtown weatherboard want to sand and polish the original boards. Do it after reblocking. Sanding an uneven floor removes more timber from the high spots and leaves a floor that looks wavy. Once the house is re-levelled, the boards sand evenly and the finish lasts.

Budgeting for it

A reblock is a significant cost, and it's understandable to want to put it off until after the "visible" renovation. But fixing the foundations later almost always costs more overall, because finished work gets damaged and redone. Our guide to how much reblocking costs in Geelong explains what drives the price, and the Reblocking & Restumping service page covers what's included.

Talk to us before you finalise plans

If you're planning a renovation or extension on an older home anywhere in Geelong, the northern suburbs or the Bellarine, book an inspection before the plans are locked in. We'll tell you plainly whether the floor needs work, how much, and how to fit it in with your other trades.
