Methods for 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 resin grout
A resin grout bonds quickly and strongly to the bar and masonry and suits wet conditions or work that must take load sooner. It is less forgiving of soft or crumbly bricks, so the choice of grout is made wall by wall rather than as a rule.
Best for: Dense bricks, damp walls and repairs needing a fast cure

Confirm the cause has stopped
Before quoting we check what made the wall crack and whether it is still moving. If there is doubt, we suggest a period of monitoring or an engineer’s view, rather than stitching a crack that will simply open again.
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.
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.
Symptoms that point to crack stitching
- A crack you can fit a coin into, running through bricks and mortar
- A crack visible on both the inside and outside face of the wall
- Stepped cracking beside a window, door or corner
Rules for crack stitching in Wales
In Wales, small like-for-like repairs do not usually need approval, but work that alters or strengthens the structure needs building control under the Welsh Building Regulations, and the Party Wall etc. Act 1996 can apply to shared walls.
Frequently asked questions
How much will crack stitching cost in Llantwit Major?
Guide prices for crack stitching in Llantwit Major 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 Llantwit Major?
Yes, Llantwit Major is covered, along with postcode districts CF61. We also cover nearby Bridgend and Barry.
Is the ground in South Glamorgan prone to subsidence?
Cardiff is built on Mercia Mudstone, river gravels and alluvium, and the Vale of Glamorgan on Lias limestone and clay. Soft alluvium near the rivers and docks can settle. 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.
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.
