Crack stitching in Blyth

Methods for crack stitching
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 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
From first photo to finished repair
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.
Symptoms that point to crack stitching
- A crack you can fit a coin into, running through bricks and mortar

Frequently asked questions
What is the price of crack stitching in Blyth?
Guide prices for crack stitching in Blyth 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 Blyth?
We do. Blyth and the surrounding area are covered, including nearby Bedlington and Ashington. A free initial assessment from your photos is the first step.
Does the ground around Blyth cause cracking?
South-east Northumberland around Blyth, Ashington and Cramlington lies on the Northumberland coalfield, worked extensively in the past, under a cover of glacial clay. The north and west are hard rock and moorland. 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.
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.
