Worth a prompt inspection before movement worsens.

Likely cause

Stepped cracking above a window on a ring foundation — localised movement on clay soils.

Repair direction

Most likely: Localised underpinning of the affected corner plus drainage improvement.

Who this is for

Understand how serious a foundation or structural issue might be before you call in the experts.

For buyers
Eyeing a property?

Cracks, sloping floors, or a foundation note in the building report. Get a fast first-pass read to help decide whether to proceed, renegotiate, bring in an engineer, or walk away.

For homeowners
Noticed something change?

New cracks, sticking doors, uneven floors, or damp. Or sanity-checking a contractor’s quote before you commit. A neutral first pass to help you work out what to look into next.

A first-pass triage to help you prioritise — not engineering advice, and not a substitute for a professional inspection.

What you get

Best for
Concerned homeowners, buyers, property managers, agents and inspectors — to understand foundation issues.
Important
Use this to prioritise further inspection, not replace it. Add context if the app asks for it.
