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.
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.

How we usually approach structural surveys and crack monitoring
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
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
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.
Questions about structural surveys and crack monitoring in Gainsborough

Guide prices for structural surveys and crack monitoring in Gainsborough start from about £490 per property, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Lincolnshire crack?
Lincolnshire has Lias, Oxford and Kimmeridge clays on the vales, chalk on the Wolds and soft silts and peat in the fens around Boston and Spalding. Fen ground and clay can both settle or shrink in dry years. Only an investigation can say why a particular building has moved.
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.
What is a tell-tale on a crack?
A tell-tale is a small gauge fixed across a crack, with two overlapping plates marked in millimetres. As the crack opens, closes or shears, the plates move against each other and the reading changes. It gives a simple, repeatable record that anyone can check between visits.
