What should you know about the ground under Norfolk?
Norfolk is chalk covered by glacial sands, gravels and boulder clay, with fen silts in the west and soft cliffs on the north-east coast. Boulder clay areas can shrink near trees, and historic chalk mines are recorded under parts of Norwich.
Ground movement here is more often linked to soils, drains and trees than to mining. Across Norfolk, most homes are flint and brick cottages, Victorian terraces in Norwich and Great Yarmouth, and post-war bungalows.
Repair options we may recommend
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
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 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.
Is it time for structural surveys and crack monitoring? Common signs

Do you need approval for structural surveys and crack monitoring in England?
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.

Why do houses in Norfolk crack?
Norfolk is chalk covered by glacial sands, gravels and boulder clay, with fen silts in the west and soft cliffs on the north-east coast. Boulder clay areas can shrink near trees, and historic chalk mines are recorded under parts of Norwich. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will structural surveys and crack monitoring cost in Norfolk?
On East of England rates, structural surveys and crack monitoring starts from about £525 per property, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
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 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.
