What happens during structural surveys and crack monitoring, step by step?
Free initial assessment
Send photos of the cracks with something for scale and tell us when they appeared. We give a free view on whether an engineer’s inspection is worthwhile, and whether your insurer should be told first.
Engineer’s inspection
We can arrange an independent chartered structural engineer to inspect. They record the damage, assess likely causes and recommend whether monitoring, drain surveys or trial pits are needed before any repair decision.
Repair or close
If the readings show the house is stable, the engineer specifies the repair and we confirm a fixed price in writing. If movement continues, the cause is investigated further before a foundation repair is designed.

How we usually approach structural surveys and crack monitoring
Engineer’s structural inspection and report
A chartered structural engineer visits, records the cracks, checks the walls, floors, drains and nearby trees, and writes a report on the likely cause and next steps. It may recommend monitoring, investigations such as trial pits, or a repair specification.
Best for: A first expert opinion on any significant cracking
Level monitoring
Survey points are fixed around the building and their heights measured against a stable datum on each visit. This shows whether one part of the house is dropping or rising compared with the rest, which crack widths alone cannot reveal.
Best for: Suspected subsidence or heave across a whole house
Rules for structural surveys and crack monitoring in Wales
In Wales, small like-for-like repairs do not usually need approval, but work that alters or strengthens the structure needs building control under the Welsh Building Regulations, and the Party Wall etc. Act 1996 can apply to shared walls.
Questions about structural surveys and crack monitoring in Rhondda
How much should I budget for structural surveys and crack monitoring in Rhondda?

Why do houses in Mid Glamorgan crack?
Mid Glamorgan lies on the South Wales coalfield, with dense historic workings, spoil tips and steep valley sides. Landslip, retaining walls and mining legacy are all live issues in the valleys. Only an investigation can say why a particular building has moved.
When should I get a structural engineer’s report?
It is worth getting one when cracks are wider than a few millimetres, tapered, getting worse, or accompanied by sticking doors and sloping floors. A mortgage valuer or insurer asking for one is another clear trigger. Fine, stable hairline cracks often do not need one.
What is a tell-tale on a crack?
A tell-tale is a small gauge fixed across a crack, with two overlapping plates marked in millimetres. As the crack opens, closes or shears, the plates move against each other and the reading changes. It gives a simple, repeatable record that anyone can check between visits.
