Movement in older Sunbury homes

Corner cracks, uneven floors and what they mean when you are buying.

Sunbury 3429 · 5 February 2026

In short: Older Sunbury houses often show some movement. The point of the inspection is to tell settled from ongoing.

Typical signs

Cracks at the corners of doors and windows, uneven floor levels and doors that stick are the usual signs.

Measuring, not guessing

Crack widths and floor levels are measured, which tells you more than a description.

Moisture is often the cause

Downpipes onto soil and ground falling toward the house wet the clay under one side of the footings.

When to get more advice

Where movement looks active or severe, the report recommends a structural engineer.

FAQ

Questions Sunbury owners ask about this

Are corner cracks serious?

Fine cracks from long-term settling are common. Wider or growing cracks need more investigation.

Can drainage stop movement?

Improving drainage often reduces it by keeping moisture under the house more even.

Will the report say whether to buy?

No. It sets out the condition so you can decide.

Do you go under the floor?

Yes, when the subfloor can be entered safely.
