Structural surveys and crack monitoring in Hackney
For homeowners in Hackney 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 Hackney?

Shrinkable clay is widespread in Greater London. Ground movement here is more often linked to soils, drains and trees than to mining. Across Greater London, most homes are Victorian and Edwardian terraces with shallow footings, inter-war semis in the outer boroughs, and converted flats and mansion blocks.

Methods for structural surveys and crack monitoring
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
From first photo to finished repair
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.

Why do houses in Greater London crack?
Most of Greater London sits on London Clay, among the most shrinkage-prone ground in the UK, with river gravels along the Thames. Subsidence claims here are among the most frequent in the country, especially after dry summers and near street and garden trees. 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.
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.
