Weatherboard or timber floors? You're looking at restumping.
Older homes on timber, concrete or steel stumps sink as stumps rot or soil moves. Replacing them is called restumping — or reblocking in Melbourne.
What is restumping?Cracks in your walls? Floors starting to slope?
It's usually the ground moving under your house — and it's usually fixable. Restumping Help explains what's happening in plain English, what a fix really costs, and puts you in touch with licensed local firms.

Slab or brick home
What kind of home do you have?
The fix — and the word for it — depends on what your house sits on.
Concrete slab or full brick? That's underpinning territory.
When a slab or strip footing settles unevenly, the footing itself is strengthened and re-supported. That job is called underpinning.

Common questions
Worried? Start with these
Are cracks in my walls serious?
Most hairline cracks under 1 mm are cosmetic. Cracks wider than 5 mm, cracks that keep growing, or cracks paired with sloping floors and sticking doors are worth a professional look. Read the crack guide.
What's the difference between restumping, reblocking and underpinning?
Restumping and reblocking are the same job — replacing the stumps under a timber-floored house. Reblocking is simply the Melbourne word for it. Underpinning strengthens the footings of slab or brick homes. Full terminology guide.
How much does restumping cost?
Around $500–$700 per stump supplied and installed, or roughly $15,000–$30,000 for a full house, depending on access, stump material and how level the house needs to be. See the cost guide.
Do I need a permit?
In most states, yes — restumping is structural work. Victoria requires a building permit and a registered practitioner; Queensland has extra rules if the house is being raised. Check your state's rules.
