Buying or selling in the ACT?

Every ACT home sale needs a seller's building and compliance report. It often flags decks, pergolas, carports or extensions built without approval.

We assess those structures and tell you what they need. If you're buying, we check structural concerns before you sign. The report, explained.

180 days

Buyers can't rely on a seller's report for contracts entered more than 180 days after its inspection.

Get a second opinion before you pay for the repair

Contractors assess for free because they sell the fix. We don't sell repairs, so our advice doesn't depend on what you buy next.

  • UnderpinningIs the movement still going, and does the scope match it?
  • Resin injectionDoes it deal with the cause, or only the symptom?
  • Re-levellingIs the floor moving, or was it built out of level?
  • Wall removalIs the wall load-bearing, and is the proposed beam right?

Why Canberra houses crack and move

The ground here changes a lot from block to block and from year to year. That's why we look at your site, not a suburb average. Read Canberra soils and footings.

Soil

Most Canberra suburbs sit on a soil landscape the ACT's own soil mapping flags for a 'widespread foundation hazard'.

Rock

Rock under Canberra is often deeply and unevenly weathered. One block can go from shallow rock to deep clay.

Wall removal

Removing a load-bearing wall in the ACT needs building approval. Wall removal and beam design

Retaining walls

Retaining walls over 1.2 m must meet design standards and above 1.5 m need building approval. Near a boundary the planning limit is 0.4 m. Retaining walls

How much does a structural engineer cost in Canberra?

From $390 + GST ($429 inc GST) for a desktop review, such as a second opinion on an underpinning quote. A structural inspection and report is $1,090 + GST ($1,199 inc GST). Every price is on our prices page, and your quote is fixed before we start.

Do I need approval to remove a wall?

Yes, if it's load-bearing. Removing a load-bearing wall in the ACT needs building approval from a certifier. We design the beam and supports and give you the documents the certifier needs. See wall removal and beam design.

Do you work in Queanbeyan?

Yes. Queanbeyan, Jerrabomberra and Googong are at the same prices as Canberra. They're in New South Wales, so NSW rules apply to approvals there. See areas we cover.

Do you sell or recommend repairers?

No. We don't sell repairs or builds and we don't recommend repairers. You get the engineering, then choose who does the work.

What do I send for a quote?

A few photos of the problem or your plans, the suburb, and a line about what you need. We reply with a fixed quote in under 20 minutes on average, during business hours.

Do you write the seller's building and compliance report?

No. We assess the structures that report often flags, such as decks, pergolas, carports or extensions built without approval, from $690 + GST ($759 inc GST). See unapproved structure assessments.
