Crack stitching in Exeter
Before we stitch a crack at a Exeter 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.

Why does the ground in Devon matter for crack stitching?
We cover Exeter and its postcode districts EX1, EX2, EX3, EX4, part of Devon, with a population of roughly 130,000. Nearby places we cover include Exmouth (9 miles), Tiverton (12 miles) and Newton Abbot (14 miles).
Clay shrinkage is less of a concern in Devon, so other causes such as drains, poor footings or older walls are checked first. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Devon, most homes are cob and stone cottages, Victorian terraces in Exeter, Plymouth and Torbay, and post-war estates.
How we usually approach 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
What happens during crack stitching, step by step?
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.
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.
What to look for before calling about crack stitching
- Cracking that a surveyor or engineer has said is now stable
- Stepped cracking beside a window, door or corner
- 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.
Questions about crack stitching in Exeter
What is the price of crack stitching in Exeter?
Guide prices for crack stitching in Exeter 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.

Yes, Exeter is covered, along with postcode districts EX1, EX2, EX3, EX4. We also cover nearby Exmouth and Tiverton.
Does the ground around Exeter cause cracking?
Devon's ground is mostly older mudstones, sandstones and granite, so shrinkable-clay subsidence is less widespread than further east. Older solid-walled and cob buildings, steep sites and retaining walls are the more common structural concerns. 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.
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.
