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
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
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.
Written quote
You receive a no-obligation written quote listing each crack, the repair method chosen for it and the making good inside and out. Once the scope is settled, that becomes a fixed price in writing.

Rules for structural crack repairs in Wales

Questions about structural crack repairs in Llangefni
What is the price of structural crack repairs in Llangefni?

Does the ground around Llangefni cause cracking?
Gwynedd and Anglesey are mostly hard rock with glacial deposits, so clay shrinkage is uncommon. Historic slate quarrying and metal mining have left tips and workings in places. Only an investigation can say why a particular building has moved.
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.
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.
