Reblocking (sometimes called restumping) is a distinctive Melbourne specialty. California bungalows, Federation villas, early inter-war housing, and many 1940s-1960s timber-framed homes in Melbourne's western and northern suburbs sit on timber stump foundations. Over 80-100 years the timber stumps rot, termites burrow through them, and reactive-clay soils in the western and northern suburbs (Sunshine, Footscray, Altona, Essendon, Moonee Ponds, Brunswick, Coburg, Pascoe Vale) drive differential settlement.

Reblocking replaces the timber stumps with concrete stumps, concrete piers, or helical screw piles. VBA registration as a reblocker is required. A Building Permit is required in almost all cases. A structural engineer reviews the design and certifies the completed work for insurance purposes. Termite retreatment under AS 3660 is standard practice on the restored footings.

AskBaily routes your Melbourne reblocking to a VBA-registered reblocker with structural engineer on-panel and termite retreatment coordination.

What a Melbourne reblocking project involves

Assessment. Structural engineer + geotechnical review. Tell-tale signs: sloping floors, door stickiness, plaster cracks.
Permits. Building Permit. VBA-registered reblocker.
Works. Excavation around each stump, new concrete stump or helical pile, relevel, reframe.
Termite. AS 3660 retreatment on restored area.
Duration. 1-3 weeks for typical home. House habitable throughout.

Frequently asked questions

Do I need to restump to concrete? For structural reliability yes — timber stumps have a 60-80 year service life on reactive-clay soils. Concrete is 80-120 years.

How much does Melbourne reblocking cost? A$12,000-A$18,000 for partial (8-15 stumps replaced). A$22,000-A$32,000 for full reblock of a small cottage. A$38,000-A$42,000+ for larger California bungalows.

“A string of bright beads of sunlight, breaking through the valleys along the moon’s rim.”

— Francis Baily, 1836

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.
