Cracks and structural soundness in a Berwick rental

When a crack is cosmetic, and when it points to something the standard cares about.

Berwick 3806 · 2 October 2026

In short: Structural soundness is one of the 15 standards. Most cracks are minor, but a pattern of them tells a story.

What the standard requires

The home must be structurally sound and weatherproof.

Fine settlement cracks

Hairline cracks in plaster are common in older homes and are recorded for monitoring.

When to look further

Wider cracks, doors that bind and floors out of level together point to movement worth investigating.

Mould as a sign

Mould on ceilings can show where water is getting in, which affects weatherproofing too.

Next steps

Where we see signs of movement, we suggest a defect investigation before the property is listed.
