Crack stitching in St Austell
Got a crack you can slip a coin into? In St Austell, as anywhere, that is usually wide enough to justify stitching rather than filling, provided an engineer or surveyor agrees the wall has stopped moving.

Methods for crack stitching
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

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.
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.
Symptoms that point to crack stitching
- Stepped cracking beside a window, door or corner
- A crack visible on both the inside and outside face of the wall
- A crack you can fit a coin into, running through bricks and mortar
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.
Frequently asked questions
How much should I budget for crack stitching in St Austell?
Guide prices for crack stitching in St Austell start from about £80 per metre of crack, including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in St Austell?
We do. St Austell and the surrounding area are covered, including nearby Bodmin and Truro. A free initial assessment from your photos is the first step.
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.
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.
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.
