Crack stitching in Thurso
Before we stitch a crack at a Thurso property, we want to know why it opened and whether it has stopped. Stitching a wall that is still moving rarely holds, so the cause comes first and the bars come second.

Shrinkable clay is less common in Highland and Moray than in south-east England. Ground movement here is more often linked to soils, drains and trees than to mining.

Methods for crack stitching
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
From first photo to finished repair
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.

Frequently asked questions
What is the price of crack stitching in Thurso?
Guide prices for crack stitching in Thurso start from about £75 per metre of crack, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out crack stitching in Thurso?
Survey visits to Thurso are by arrangement because of travel and access. We can still give a free initial view from photos, and we tell you any travel cost before a visit is booked.
Does the ground around Thurso cause cracking?
The Highlands and Moray are hard rock and glacial deposits with little shrinkable clay; exposure, steep sites and older stone buildings drive most structural work. Only an investigation can say why a particular building has moved.
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.
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.
