Subsidence, settlement and heave
A crack is wider near the ceiling and dies out above the skirting. What movement does that shape suggest, and what has it not measured?
The shape suggests movement from higher in the wall, and it has measured nothing. A crack wider near the ceiling that dies out above the skirting opens more at the top than at the bottom. That taper is the pattern people associate with movement from above, such as a spreading roof or a dropping head, rather than a foundation crack wider at the floor. The survey has recorded the shape. It has not measured how far anything has moved, has not monitored the crack, and has not proved the cause. The suggestion is in the taper. The measurement is absent.

What is the fuller explanation?
A crack that gapes at the ceiling and pinches out before the skirting is hinged towards the top of the wall. Roof spread, a rotated beam, or shrinkage at a high level can all leave that drawing, and they are not the same repair. The survey can describe the taper without picking one of them. What it cannot do from a single visit is measure rate, direction over time, or the length the rafters have pushed.
Ask the surveyor to say the taper in plain words and to list what was not measured. If the top of the wall or the roof is the suspect, that is the next inspection, not a foundation story copied from a different shape. Tell the solicitor the survey has not put a figure on the movement. A lender should see a described taper, not an invented displacement, and an insurer should not be handed a cause the crack width was never used to prove.
What should you ask your surveyor?
- Is the crack wider near the ceiling and closed above the skirting?
- What, if anything, did you measure rather than describe?
- Are you suggesting movement from above without naming a proved cause?
What are the typical next steps?
- Describe the taper as wider at the ceiling.
- Do not treat that shape as a measured movement.
- If the roof is the suspect, inspect the top of the wall next.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
If the ceiling rose is off centre, has the shift been measured?
No. An off-centre rose is a finishing observation, not a measured movement of the crack. The survey recorded a taper and did not measure how far the wall or the ceiling has travelled. The rose does not supply that figure.
Does a hairline at the top still count as this shape?
Only if it is still wider at the ceiling than lower down. The survey's point is the taper, not a width. A fine crack can show the shape and still be unmeasured, which is the limit of this note. The inspection did not stretch the top-heavy crack into any wider claim at all.
