Crack stitching in Llanelli
Many Llanelli homeowners find a crack that has been filled twice and reopened both times. That pattern usually means the masonry needs bonding back together, and helical bar stitching does exactly that once the movement behind it has ended.

Why does the ground in Dyfed matter for crack stitching?
Llanelli is in Dyfed and takes in postcode districts SA15. About 50,000 people live there. We also take enquiries from nearby Gorseinon (5 miles), Swansea (10 miles) and Ammanford (11 miles).
Clay shrinkage is less of a concern in Dyfed, so other causes such as drains, poor footings or older walls are checked first. Parts of Dyfed lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Dyfed: stone cottages, Victorian terraces in Llanelli and Carmarthen, and post-war estates.
What to expect when we carry out crack stitching
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.

Repair options we may recommend
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
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.
Your crack stitching questions
How much should I budget for crack stitching in Llanelli?
Guide prices for crack stitching in Llanelli 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.

Why do houses in Dyfed crack?
The western edge of the South Wales coalfield lies beneath Llanelli, Ammanford and parts of Pembrokeshire, while the rest of the area is older hard rock with glacial deposits in the valleys. 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.
