Structural crack repairs in Cowes
A cracked wall in Cowes does not automatically mean subsidence. Thermal movement, rusting wall ties, tired lintels and old drains each leave their own pattern, and we look at the whole picture before recommending any repair to the brickwork.

How we usually approach structural crack repairs
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
Rebuilding a cracked section
Where bricks have split or the wall has moved out of line, the damaged area is taken down and rebuilt, bonded into sound masonry on either side. Reclaimed or matched bricks keep the repair discreet, with temporary support used where needed.
Best for: Badly displaced or broken brickwork
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.
Survey and record
On site we measure the width along the crack, note its pattern and check nearby drains, trees and openings. If the cause is unclear, gauges can be fixed across it and read over several months.
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.

Questions about structural crack repairs in Cowes

Is the ground in Isle of Wight prone to subsidence?
The island has clays, sands and chalk, and the south coast around Ventnor sits on one of the largest urban landslide complexes in Europe. Ground movement there is a landslip question as much as a clay one. Only an investigation can say why a particular building has moved.
Can I just fill a crack and paint over it?
You can fill a fine crack that is not moving, and for many hairline cracks that is the right repair. Filling a crack that is still opening hides the evidence, and it will usually come back. If a filled crack returns within a year or two, have it assessed.
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.
