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

What is the ground like in Dorset?
We cover Christchurch and its postcode districts BH6, BH7, BH23, part of Dorset, with a population of roughly 31,000. Nearby, we also cover Bournemouth (4 miles), New Milton (5 miles) and Ferndown (7 miles).
Parts of Dorset have clay that can shrink near trees in dry spells. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Dorset: Stone and brick villages, Victorian villas in Bournemouth, and inter-war and post-war semis.
How we usually approach crack stitching
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
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
What happens during crack stitching, step by step?
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.
Questions about crack stitching in Christchurch
What is the price of crack stitching in Christchurch?
Guide prices for crack stitching in Christchurch start from about £80 per metre of crack, including VAT, on South 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 Christchurch?
We do. Christchurch and the surrounding area are covered, including nearby Bournemouth and New Milton. A free initial assessment from your photos is the first step.
Does the ground around Christchurch cause cracking?
Dorset mixes chalk downs, Oxford and Kimmeridge Clays in the vales, and the sands and gravels of the Poole basin. Clay vales can shrink and swell, and parts of the coast are known for landslip. 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.
