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
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.
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.
What to look for before calling about structural surveys and crack monitoring
- Doors and windows sticking at some times of year only

- Cracks reopening after being filled and decorated
Rules for structural surveys and crack monitoring in Wales

Questions about structural surveys and crack monitoring in Neath
How much will structural surveys and crack monitoring cost in Neath?
Guide prices for structural surveys and crack monitoring in Neath start from about £460 per property, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Neath?
We do. Neath and the surrounding area are covered, including nearby Clydach and Swansea. A free initial assessment from your photos is the first step.
Is the ground in West Glamorgan prone to subsidence?
Swansea and Neath Port Talbot lie on the South Wales coalfield, with historic workings, tips and steep valley sides, and softer estuarine ground around the docks. Only an investigation can say why a particular building has moved.
What do BRE crack categories mean?
BRE Digest 251 groups damage by typical crack width. Category 0 is under 0.1 mm, 1 up to 1 mm, 2 up to 5 mm, 3 from 5 to 15 mm or several of about 3 mm, 4 from 15 to 25 mm, and 5 usually over 25 mm. It is a guide to severity, not a diagnosis of cause.
How long does crack monitoring take?
Monitoring normally runs for 6 to 12 months, because readings need to cover both the dry and wet seasons on clay soils. Shorter periods can be enough where the cause is clearly non-seasonal, such as a drain leak that has been repaired. The engineer decides when there is enough evidence.
