Subsidence, settlement and heave
Metal monitoring studs are fixed either side of a crack and there is no log of readings. What movement has the presence of the studs not recorded?
The studs have not recorded any movement. Metal monitoring points fixed either side of a crack show that someone intended to measure it. Without a log of readings, there is no series of distances and no direction of travel. The survey has seen the studs. It has not inherited a history from their presence, and it has not measured whether the crack is opening, closing or still. Hardware without numbers is not monitoring.

What is the fuller explanation?
Monitoring only works if the same points are measured more than once and the numbers are kept. Studs on their own are hardware. They can sit for years with no one writing a figure down. A crack can be old, live or already finished, and empty studs do not say which. The survey did not start a log and did not invent the missing readings. Presence is not a result.
Ask the seller, through the solicitor, for any log, engineer letter or insurer file that belongs to these studs. If nothing exists, the crack is unmonitored whatever the metal suggests. Do not tell a lender the crack has been stable because studs are fixed. If you need a record from now, that is a new monitoring instruction, not a reading this survey already holds.
What should you ask your surveyor?
- Are monitoring studs present with no log of readings?
- Have you refused to treat the studs as a movement record?
- Did you see the crack they sit on, without a history attached?
What are the typical next steps?
- Treat the studs as hardware, not as a log of movement.
- Ask the solicitor for any reading record the seller holds.
- Do not describe the crack as monitored when no readings exist.
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 studs look recent, has monitoring started?
Recent metal only dates the fitting, if you can date it at all. The survey found no log of readings. A new stud without a number is still not a record of movement, and the crack's behaviour stays unmeasured. Nothing has been measured yet.
Does a hairline crack between studs prove it has not moved?
No. A hairline describes today's width. It does not supply the missing log. The studs have not recorded whether that width is new, old or changing. The survey has not invented the readings that are not in the pack. Width today is not a history.
