How do local ground conditions affect crack stitching in Mid Glamorgan?
Mid Glamorgan lies on the South Wales coalfield, with dense historic workings, spoil tips and steep valley sides. Landslip, retaining walls and mining legacy are all live issues in the valleys.
Historic coal workings are recorded beneath parts of Mid Glamorgan, and a coal mining search is worth checking where movement is unexplained. Across Mid Glamorgan, most homes are long stone and brick terraces on valley sides, Victorian houses in Bridgend and post-war estates.

How we usually approach 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
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
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
What happens during crack stitching, step by step?
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.
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.
What to look for before calling about crack stitching
- Cracking that a surveyor or engineer has said is now stable
- Bricks split clean through where the crack crosses them
- Filled cracks that keep reopening along the same line
- A crack visible on both the inside and outside face of the wall
Do you need approval 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.

Questions about crack stitching in Mid Glamorgan
Does the ground around Rhondda cause cracking?
Mid Glamorgan lies on the South Wales coalfield, with dense historic workings, spoil tips and steep valley sides. Landslip, retaining walls and mining legacy are all live issues in the valleys. Historic coal workings are recorded beneath parts of Mid Glamorgan, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.
How much will crack stitching cost in Mid Glamorgan?
On Wales rates, crack stitching starts from about £75 per metre of crack, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
Can crack stitching be done from outside only?
Often yes, especially on cavity walls where only the outer leaf has cracked. On solid walls, or where the crack shows clearly inside, bars may be needed on both faces to reconnect the full thickness. We check both sides before quoting.
Will crack stitching be visible afterwards?
Usually only slightly, because the bars sit inside the mortar joints and are pointed over. The main giveaway is the colour of new mortar, which can take a few months to weather. Careful mortar matching keeps the line discreet, especially on older brickwork.
