Crack stitching in Colwyn Bay
Got a crack you can slip a coin into? In Colwyn Bay, as anywhere, that is usually wide enough to justify stitching rather than filling, provided an engineer or surveyor agrees the wall has stopped moving.

What is the ground like in Clwyd?
Postcode districts LL28, LL29 cover Colwyn Bay, a Clwyd town of about 29,000 people. Nearby, we also cover Llandudno (5 miles), Abergele (6 miles) and Rhyl (10 miles).
Parts of Clwyd have clay that can shrink near trees in dry spells. Parts of Clwyd lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Clwyd: Brick colliery terraces, seaside villas in Rhyl and Colwyn Bay, and post-war estates.
Methods for crack stitching
Helical bars in cementitious grout
The most common approach. A slot is cut along the bed joint with a twin-blade cutter, flushed out and part filled with a cement-based grout. The helical bar is pushed in, more grout is packed over it, and the joint is pointed to match. The grout cures over a few days.
Best for: Most brick and block walls, including older softer bricks
Stitching with crack injection
Once the bars are in, the crack itself is filled. Fine cracks are pointed in matching mortar, while wider or deeper cracks can be injected with grout so the void inside the wall is filled rather than just the face. On older houses, lime mortar keeps the repair breathable.
Best for: Deep cracks running through the full thickness of the wall

Set out the bars
Bar positions are marked across the crack, typically every few courses up its full height, with each bar extending well into sound brickwork on both sides. An engineer’s specification, where there is one, sets the exact spacing and length.
Cut, clean and grout
Slots are cut into the bed joints to the right depth, dust is blown and washed out, and grout is placed. The bars are pressed home and covered, and the crack line is filled or injected.
Make good and record
Internal plaster cracks are cut out and filled where included, and dust is cleared. You receive a short note of where the bars went, which is useful for future buyers, surveyors and any insurance file.

Frequently asked questions
How much should I budget for crack stitching in Colwyn Bay?
Guide prices for crack stitching in Colwyn Bay start from about £75 per metre of crack, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Colwyn Bay?
Yes, Colwyn Bay is covered, along with postcode districts LL28, LL29. We also cover nearby Llandudno and Abergele.
Why do houses in Clwyd crack?
The North Wales coalfield runs beneath parts of Wrexham and Flintshire, where historic workings are recorded, while the coast and vale have glacial clays and the hills are older hard rock. Only an investigation can say why a particular building has moved.
Can I stitch a crack myself?
It is possible on a small, stable crack, but the work involves cutting into joints with a twin-blade cutter, controlling silica dust and placing the bars correctly. If the crack is part of an insurance claim or is wide, have it assessed first, because a poor repair can hide ongoing movement.
Is resin or cement grout better for crack stitching?
Neither is better in every case. Cement-based grout suits most walls and is kinder to soft, older bricks, while resin grout bonds faster and copes better with damp. The choice depends on the masonry, the conditions and any engineer’s specification.
