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.
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.
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 Darlington?
Guide prices for crack stitching in Darlington start from about £75 per metre of crack, including VAT, on North East 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 Darlington?
Yes. We take enquiries from across Darlington, including DL1, DL2, DL3, and from nearby places such as Newton Aycliffe and Yarm. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Darlington cause cracking?
Much of County Durham sits on the Durham Coalfield, worked for centuries, often under a cover of glacial clay. Many former pit villages have recorded mine workings, and coal mining searches are standard for property here. Only an investigation can say why a particular building has moved.
Is resin or cement grout better for crack stitching?
Neither is better in every case. Cement-based grout suits most walls and is kinder to soft, older bricks, while resin grout bonds faster and copes better with damp. The choice depends on the masonry, the conditions and any engineer’s specification.
Can crack stitching be done from outside only?
Often yes, especially on cavity walls where only the outer leaf has cracked. On solid walls, or where the crack shows clearly inside, bars may be needed on both faces to reconnect the full thickness. We check both sides before quoting.
