Crack stitching in Boston
Stitched repairs suit most brick and block walls in Boston, 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.

Repair options we may recommend
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
What to expect when we carry out crack stitching
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.
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.
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 Boston?
Guide prices for crack stitching in Boston 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.
Do you carry out crack stitching in Boston?
We do. Boston and the surrounding area are covered, including nearby Spalding and Sleaford. A free initial assessment from your photos is the first step.
Does the ground around Boston cause cracking?
Lincolnshire has Lias, Oxford and Kimmeridge clays on the vales, chalk on the Wolds and soft silts and peat in the fens around Boston and Spalding. Fen ground and clay can both settle or shrink in dry years. Only an investigation can say why a particular building has moved.
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.
Can I stitch a crack myself?
It is possible on a small, stable crack, but the work involves cutting into joints with a twin-blade cutter, controlling silica dust and placing the bars correctly. If the crack is part of an insurance claim or is wide, have it assessed first, because a poor repair can hide ongoing movement.
