Structural surveys and crack monitoring in Greenwich
Ground across Greenwich and Greater London 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.

What happens when we carry out structural surveys and crack monitoring in Greenwich?
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.
Signs you may need structural surveys and crack monitoring

Which repair method suits a home in Greenwich?
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
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.
Structural surveys and crack monitoring in Greenwich: questions and answers
How much should I budget for structural surveys and crack monitoring in Greenwich?
Guide prices for structural surveys and crack monitoring in Greenwich start from about £625 per property, including VAT, on London rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Greenwich?

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.
When should I get a structural engineer’s report?
It is worth getting one when cracks are wider than a few millimetres, tapered, getting worse, or accompanied by sticking doors and sloping floors. A mortgage valuer or insurer asking for one is another clear trigger. Fine, stable hairline cracks often do not need one.
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.
