Structural surveys and crack monitoring in Croydon
Cracks in a Croydon home can look alarming without being active. Measured monitoring over the seasons, with tell-tales or level points, is how an engineer separates old, settled damage from movement that is still under way.

What should you know about the ground under Croydon?
Croydon is one of the 32 London boroughs, with around 390,000 residents in districts such as CR0, CR2, CR5, CR7, CR8. Nearby, we also cover Sutton (5 miles), Caterham (5 miles) and Banstead (6 miles).
Much of Greater London sits on clay that shrinks in dry summers and swells in wet winters. 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
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
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
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.
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.
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.
Frequently asked questions
What is the price of structural surveys and crack monitoring in Croydon?
Guide prices for structural surveys and crack monitoring in Croydon 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.
Do you carry out structural surveys and crack monitoring in Croydon?
We do. Croydon and the surrounding area are covered, including nearby Sutton and Caterham. A free initial assessment from your photos is the first step.
Does the ground around Croydon cause cracking?
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.
Can I monitor cracks myself?
You can keep a useful record by photographing cracks with a ruler and pencilling dated marks at their ends. That helps an engineer, but it does not replace measured monitoring, which insurers and lenders usually expect. Do not fill or decorate over cracks while monitoring.
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.
