What to expect when we carry out structural surveys and crack monitoring

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.
Install monitoring points
Tell-tales, measuring studs or level points are fixed at the locations the engineer chooses. A base reading is taken on the first visit, so every later reading can be compared against it.
Seasonal readings
Readings are taken at intervals across the seasons, typically including late summer when clay is driest and late winter when it is wettest. The engineer checks each set against the base reading and decides whether more visits are needed.

Tell-tales and crack-width monitoring

Gauges are fixed across key cracks and read at set intervals, or reference studs are measured with callipers to a fraction of a millimetre. The readings show whether each crack is widening, closing or stable, and whether any change follows the seasons.

Best for: Tracking individual cracks over the seasons

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

Rules for structural surveys and crack monitoring in Wales

Your structural surveys and crack monitoring questions

How much will structural surveys and crack monitoring cost in Llantrisant?

Do you cover Llantrisant?

We do. Llantrisant and the surrounding area are covered, including nearby Pontypridd and Tonypandy. A free initial assessment from your photos is the first step.

Is the ground in Mid Glamorgan prone to subsidence?

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.

Can I monitor cracks myself?

You can keep a useful record by photographing cracks with a ruler and pencilling dated marks at their ends. That helps an engineer, but it does not replace measured monitoring, which insurers and lenders usually expect. Do not fill or decorate over cracks while monitoring.

What happens after the monitoring ends?

If the readings show the building is stable, the engineer specifies a repair, usually crack stitching and making good. If movement continues, further investigation and a foundation repair design follow. Either way, we confirm a fixed price in writing once the repair is specified.
