Structural surveys and crack monitoring in St Ives
Ground across St Ives and Cambridgeshire varies, and on clay the same crack can open in summer and close in winter. Readings taken in both seasons show the engineer which pattern applies before anyone decides on a repair.

Why does the ground in Cambridgeshire matter for structural surveys and crack monitoring?
St Ives is in Cambridgeshire and takes in postcode districts PE27. About 17,000 people live there. If you are just outside St Ives, we also cover Huntingdon (5 miles), St Neots (11 miles) and Cambridge (12 miles).
Cambridgeshire is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. Across Cambridgeshire, most homes are Victorian terraces in Cambridge and Peterborough, fen-edge cottages, and extensive post-war and new-build estates.
Repair options we may recommend
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
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
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.
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.

Your structural surveys and crack monitoring questions

Why do houses in Cambridgeshire crack?
Gault Clay underlies much of the Cambridge area and Oxford Clay the west of the county around Peterborough and Huntingdon, while the northern fens are peat and silt that can shrink as they dry. Both clay and peat ground can move with the seasons. 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.
