Is East Sussex prone to ground movement?
Crowborough, East Sussex: about 22,000 residents across postcode districts TN6. Neighbouring towns we cover: Tunbridge Wells (7 miles), Uckfield (7 miles) and East Grinstead (9 miles).
Much of East Sussex 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. Typical buildings in East Sussex: Regency and Victorian terraces on the coast, Wealden timber-framed houses, and inter-war bungalows and semis.

How we usually approach structural crack repairs
Crack stitching with helical bars
Stainless steel helical bars are grouted into slots cut along the bed joints, bridging the crack so the masonry works as one piece again. It is the standard repair for wider stepped and vertical cracks once whatever caused them has stopped.
Best for: Stable cracks wider than about 5 mm, or ones that keep reopening
Filling and repointing
For hairline and narrow cracks that have stopped moving, the crack line is raked out and repointed in mortar matched to the original for strength, colour and texture. Inside, plaster cracks are cut out, filled with a flexible filler and redecorated.
Best for: Cracks up to about 5 mm that are no longer moving
What happens during structural crack repairs, step by step?
Send photos
Photograph the crack from a distance and close up, with a coin or tape measure for scale. From these we say whether it looks cosmetic, needs a visit or calls for an engineer.
Deal with the cause
Leaking drains, failed ties, a sagging lintel or ground movement are put right first, sometimes through an insurance claim. Repairing a crack before its cause is fixed usually means paying for the same job twice.
Repair and make good
Cracks are stitched, repointed or rebuilt as specified, with mortar matched to the existing wall. Internal crack lines are filled and redecorated where included, and you get a written note of what was done.
Rules for structural crack repairs 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.

Is the ground in East Sussex prone to subsidence?
Inland East Sussex is Weald Clay and Wealden sands, while the South Downs and the coast around Brighton and Eastbourne are chalk. The Weald Clay areas are prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.
What causes vertical cracks in walls?
Vertical cracks are most often caused by thermal or moisture movement in long walls, or by the joint between old and newer work. An even-width vertical crack is usually cosmetic. One clearly wider at the top or bottom can indicate foundation movement at one end.
When is a crack in a wall structural?
A crack is more likely to be structural when it is wider than about 5 mm, tapers, passes through the whole wall or keeps growing. BRE Digest 251 treats damage up to about 5 mm as aesthetic and over 25 mm as a stability concern. Width is a guide, not a diagnosis.
