Underpinning Brisbane

Underpinning in Brisbane is building work: Brisbane City Council classes excavation directly related to it as building work, and Queensland requires a QBCC licence for building work above a small threshold. House Underpinning Brisbane passes each enquiry to one independent provider, who inspects the house and quotes. We don't underpin and we don't set the price.

  • One independent local provider receives your enquiry; it is not sent round a list of underpinning businesses.
  • We don't underpin and we don't set prices. The provider quotes after seeing the house.
  • Calls to this number begin with a notice that they may be recorded.

Before you call anyone

Four facts that change the job

  • Council counts it as building work Brisbane City Council's guideline classes filling or excavation directly related to underpinning as building work, and names underpinning works below an existing building as an example. Whether a particular job needs a building approval is a question for a licensed building certifier.
  • Small leaks start big movements CSIRO's footing guide says even a minuscule leak can saturate a clay foundation, and that a leaking tap beside a house can do the same. Blocked gutters, downpipes that end at the wall and over-watered garden beds sit on the same list.
  • Not every crack is a foundation problem Queensland's building regulator treats hairline cracks, and cracks that are noticeable but easily filled, as normal movement. It treats bulging walls, and doors or windows that stick and distort, as signs of a problem worth investigating.
  • A map is a start, not a finding Queensland's geological survey maps the rock and sediment under Brisbane, and we read it for every suburb with a page here. It shows what kind of ground to expect, not what your footings sit on; CSIRO says soil classification generally comes from a geotechnical report.

Three steps

From enquiry to quote

  1. Describe what you see Your suburb, the signs (cracks, sticking doors, a sloping or bouncy floor, a step in a slab) and when you first noticed them.
  2. It is referred on Your enquiry goes to an independent provider covering Brisbane. We are paid for passing it on, never by you.
  3. The provider inspects and quotes The provider looks at the house, works out the cause and prices the job. We don't set the price.

Underpinning across Brisbane

Brisbane's ground is not one thing. Across our five-point samples, Queensland's geological survey puts granite mostly under The Gap, phyllite mostly under Enoggera and older sedimentary rock mostly under Coorparoo. Bald Hills, Murarrie and Coopers Plains mix rock formations with alluvium, coastal deposits or made ground, and Bridgeman Downs carries a hard weathered surface. That is why the seven suburb pages here each read differently, and why none of them can say what is under your footings. A survey at that scale shows what kind of ground to expect; on CSIRO's account, the classification of your own block generally comes from a geotechnical report.

Where enquiries come from

Suburbs we cover

Enquiries reach this site from across Brisbane City Council's area. Seven suburbs have a page of their own, each written around what the public record shows for that suburb: The Gap, Enoggera, Bald Hills, Bridgeman Downs, Murarrie, Coopers Plains and Coorparoo.

Suburbs without a page, Greenslopes and Norman Park among them, are covered on the same terms.
