Which repair method suits a home in St Helens?
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
What happens when we carry out crack stitching in St Helens?
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.
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.
Signs you may need crack stitching
- A crack visible on both the inside and outside face of the wall
- Filled cracks that keep reopening along the same line
- 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.
Crack stitching in St Helens: questions and answers
How much will crack stitching cost in St Helens?
Guide prices for crack stitching in St Helens start from about £75 per metre of crack, including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover St Helens?
We do. St Helens and the surrounding area are covered, including nearby Prescot and Ashton-in-Makerfield. A free initial assessment from your photos is the first step.
Is the ground in Merseyside prone to subsidence?
Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places. Only an investigation can say why a particular building has moved.
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.
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.
