Structural surveys and crack monitoring in Gravesend
For homeowners in Gravesend unsure whether a crack is getting worse, the honest answer often needs measurement rather than a single look. Tell-tales and level points turn the question into clear figures the engineer can interpret.

What should you know about the ground under Gravesend?
Postcode districts DA11, DA12 cover Gravesend, a Kent town of about 54,000 people. Nearby, we also cover Swanscombe (3 miles), Longfield (4 miles) and Strood (6 miles).
Much of Kent sits on clay that shrinks in dry summers and swells in wet winters. Parts of Kent lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.

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
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.
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.
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 Gravesend
How much should I budget for structural surveys and crack monitoring in Gravesend?
Guide prices for structural surveys and crack monitoring in Gravesend start from about £560 per property, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Kent crack?
North Kent sits on London Clay, central Kent on Gault and Weald Clays and the Downs on chalk, so shrinkable clay is widespread. East Kent around Deal and Dover had a small deep coalfield, worked until the late 1980s. Only an investigation can say why a particular building has moved.
Who carries out the crack monitoring?
An independent chartered structural engineer designs the monitoring and interprets the readings. We can arrange the engineer for you. We are the repair contractor, so we carry out the repair the engineer specifies once the monitoring has shown what is needed.
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.
