How we usually approach structural surveys and crack monitoring
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 happens during structural surveys and crack monitoring, step by step?
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.
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.
Rules 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.

Does the ground around Bishop's Stortford cause cracking?
South Hertfordshire around Watford, Borehamwood and Potters Bar is London Clay, while the north and west are chalk with clay-with-flints and the east has boulder clay. The clay areas are prone to seasonal subsidence near trees. 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.
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.
