What It Means

The fix every
old weatherboard needs.

Most of inner-west Melbourne is built on timber stumps from the 1900s, 1920s, 1940s. Hardwood was cheap, plentiful, and the standard at the time. It also rots. Termites find it. Damp under the house finishes it off. By the time the floor starts to drop, the timber has usually been failing for years.

Conversion replaces every timber stump with a concrete one. Steel-capped, cast to size, installed into a fresh concrete footing pad in the ground. Same process as a full reblock, because that is what it is. The difference is the framing: this is the right call when the existing stumps are timber, not just tired concrete.

WHEN IT'S USED
Any pre-1970s home still on its original timber stumps. Edwardians, Federation, Californian Bungalows, post-war weatherboards.
WHY CONCRETE
Does not rot. Termites cannot eat it. Will outlast the house above. There is no better material for the job.
When To Do The Conversion

Six reasons to stop putting it off.

Once timber stumps go, they go quickly. The cost of doing the conversion early is always less than fixing the floor and the plaster after the stumps fail.

REASON 01
Visible rot in the stumps

Crawl under and tap a stump with a hammer. If it sounds hollow or feels soft, the timber has gone.

REASON 02
Termite activity in the sub-floor

Mud trails up the stumps, a previous treatment, or a pest report flagging activity. Concrete removes the food source.

REASON 03
Pre-renovation

Before you spend on a new kitchen, polished floors or an extension, fix what they sit on. Cheaper now than later.

REASON 04
Pre-sale or pre-purchase

Building inspections call timber stumps every time. Converting before sale removes the buyer's bargaining chip.

REASON 05
Damp sub-floor

Persistent moisture under the house rots timber stumps fastest. Concrete does not care about damp.

REASON 06
House never been reblocked

If the original timber stumps are still in, you are on borrowed time. Past 80 years they are well past their life.

Stump Conversion FAQ

The questions we get every week.

Is conversion the same as a reblock?

Yes, mechanically. Both involve replacing every stump under the house. The label "conversion" just signals that you are starting with timber, which is the most common scenario in older Melbourne weatherboards.

Why not just replace the worst stumps?

If the rest are the same age, they will fail soon. You end up paying for the same job twice, plus the disruption twice. Doing every stump in one go is always cheaper across the life of the house.

Can the house stay occupied during the conversion?

Yes, on most jobs. Work is staged so the house is fully supported throughout. You will hear us, and the floor moves a few millimetres at a time, but you do not need to move out.

Do new concrete stumps need maintenance?

No. Concrete with a galvanised steel cap is install-and-forget. There is nothing to paint, treat, brace or replace. They will outlast the house.

Will conversion add value to the house?

Yes. Building inspection reports flag timber stumps every time, and buyers use it as a price-down lever. A completed conversion with the 15-year written guarantee removes that.

Will it fix my sloping floors at the same time?

Almost always. We computer-level the whole footprint as part of the conversion, so the floor comes back to where it was meant to sit. Doors free up, cracks usually close.
