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

From first photo to finished repair
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.
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.
Symptoms that point to crack stitching
- Filled cracks that keep reopening along the same line
- A crack you can fit a coin into, running through bricks and mortar
- Stepped cracking beside a window, door or corner

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
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
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
What is the price of crack stitching in Daventry?
Guide prices for crack stitching in Daventry start from about £80 per metre of crack, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Does the ground around Daventry cause cracking?
Northamptonshire sits largely on Lias clay and Jurassic ironstones and limestones, with historic ironstone quarrying around Corby and Kettering. The clay vales are prone to shrinkage near trees. 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.
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.
