Crack stitching in Blackburn
Stitched repairs suit most brick and block walls in Blackburn, from older solid nine-inch walls to modern cavity construction. On soft historic brick we use lime mortar and grout chosen to suit it, so the repair does not damage the wall.

Is Lancashire prone to ground movement?
With roughly 150,000 people, Blackburn spans postcode districts BB1, BB2 in Lancashire. Nearby places we cover include Darwen (4 miles), Accrington (5 miles) and Chorley (9 miles).
Parts of Lancashire have clay that can shrink near trees in dry spells. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Lancashire: Stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.

Repair options we may recommend
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
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 to expect when we carry out crack stitching
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.
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.
Is it time for crack stitching? Common signs
- Bricks split clean through where the crack crosses them
- A crack visible on both the inside and outside face of the wall
- 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.
Your crack stitching questions
What is the price of crack stitching in Blackburn?
Guide prices for crack stitching in Blackburn 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 carry out crack stitching in Blackburn?
Yes, Blackburn is covered, along with postcode districts BB1, BB2. We also cover nearby Darwen and Accrington.
Does the ground around Blackburn cause cracking?
Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns. 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.
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.
