Crack stitching in Falmouth
Many Falmouth 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.

Repair options we may recommend
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
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.
Rules for crack stitching in England
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.
Your crack stitching questions
How much should I budget for crack stitching in Falmouth?

Why do houses in Cornwall crack?
Cornwall is mostly granite and slate with little shrinkable clay, so clay subsidence is less common than in the south-east. Historic tin and copper mining has left shafts and workings in places such as Camborne and Redruth, and mining searches are routine there. 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.
How far apart are helical bars placed?
Helical bars are usually placed every few courses up the full height of the crack, each one running well past the crack into sound brickwork. Spacing and bar length depend on the wall and the crack width, and where an engineer has specified the repair, their drawing sets them.
