What should you know about the ground under Llandudno?
We cover Llandudno and its postcode districts LL30, part of Gwynedd, with a population of roughly 15,000. Neighbouring towns we cover: Colwyn Bay (5 miles), Abergele (11 miles) and Rhyl (14 miles).
Most of Gwynedd is on firmer ground than the clay belts of the south-east. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Gwynedd, most homes are slate and stone terraces, chapels and cottages, Victorian seaside houses and post-war estates.
How we usually approach crack stitching
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
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
What happens during crack stitching, step by step?
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.
Repoint to match
The cut joints and crack are pointed in a mortar chosen to match the colour, texture and strength of the existing work. On older houses with soft bricks, a lime mortar is used so the repair does not trap moisture.

Questions about crack stitching in Llandudno
How much will crack stitching cost in Llandudno?
Guide prices for crack stitching in Llandudno 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.
Do you cover Llandudno?
We do. Llandudno and the surrounding area are covered, including nearby Colwyn Bay and Abergele. A free initial assessment from your photos is the first step.
Is the ground in Gwynedd prone to subsidence?
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.
Does crack stitching stop a wall moving?
No, crack stitching reconnects cracked masonry but does not stop the movement that caused it. If the ground is still shrinking, a drain is still leaking or ties are still rusting, a stitched wall can crack again nearby. The cause has to be identified and dealt with first.
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.
