Methods for 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
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

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.
Are horizontal cracks in a wall serious?
Horizontal cracks are often more serious than vertical ones, because they suggest the wall is being pushed or lifted. Cracks repeating every few courses point to rusting wall ties, while one long crack with a bulge may mean lost restraint.
What do stepped cracks in brickwork mean?
Stepped cracks usually mean part of the wall has moved and the weakest path, the mortar joints, has given way. They are common with subsidence and around openings. A thin stepped crack unchanged for years is often cosmetic, while a wide or tapered one should be looked at.
