What Surveyors Look For

Surveyors must record evidence of cracking or distortion. If the cause is unclear, they must recommend monitoring or a structural engineer’s report. (RICS Home Survey Standard, 2019 — Sections 4.8–4.10). They note location, width, and pattern — then rate severity.

Likely minor

• Fine surface cracks in plaster or paintwork, especially near doors, windows, or ceilings.

• Often due to drying shrinkage or long-settled movement.

• No matching cracks externally.

When to Worry

• Doors or windows misaligned

• Cracks run through bricks, not just plaster

• Visible widening over time

• Diagonal or stepped cracks through brickwork.

• Recent cracking with sharp edges or changes in width.

• Associated issues like sloping floors or sticking doors.

What to do next

• Seek an engineer’s opinion if cracks appear structural.

• A structural report typically costs £500-1,000 (excl. VAT)

Risks of not addressing it

If structural movement continues unchecked, it can compromise stability and significantly reduce property value or insurability.
