Crack stitching in Glasgow
Across Glasgow, requests for crack stitching usually begin with a crack someone has noticed getting wider. Clay shrinkage is less of a concern in Glasgow, so other causes such as drains, poor footings or older walls are checked first. A repair only lasts if the reason for the movement has stopped.

What is the ground like in Glasgow?
Glasgow is underlain by the Central Coalfield, with shallow historic coal and ironstone workings recorded across much of the city, beneath glacial till and river deposits along the Clyde.
Historic coal workings are recorded beneath parts of Glasgow, and a coal mining search is worth checking where movement is unexplained. Typical buildings in Glasgow: Red and blond sandstone tenements, Victorian villas, inter-war cottage flats and post-war estates.
Repair options we may recommend
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
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
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.
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.

Your crack stitching questions
Why do houses in Glasgow crack?
Glasgow is underlain by the Central Coalfield, with shallow historic coal and ironstone workings recorded across much of the city, beneath glacial till and river deposits along the Clyde. Historic coal workings are recorded beneath parts of Glasgow, 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 Glasgow?
On Scotland 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.
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.
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.
How long does crack stitching last?
Stainless steel bars do not rust, so a stitched repair in a stable wall should last as long as the surrounding brickwork. The repair only fails early when the wall keeps moving, which is why the cause is dealt with before the bars go in.
