Crack stitching in Pontypool is a tidy way to reconnect brickwork that has split, without taking the wall down. We set stainless helical bars into the mortar joints across the crack, then point over them so the repair blends in.

Is Gwent prone to ground movement?
Pontypool, Gwent: about 36,000 residents across postcode districts NP4. If you are just outside Pontypool, we also cover Cwmbran (3 miles), Abertillery (4 miles) and Abercarn (5 miles).
Parts of Gwent have clay that can shrink near trees in dry spells. Historic coal workings are recorded beneath parts of Gwent, and a coal mining search is worth checking where movement is unexplained. Across Gwent, most homes are valley terraces on steep hillsides, Victorian houses in Newport and Abergavenny, and post-war estates.
Which repair method suits a home in Pontypool?
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
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 when we carry out crack stitching in Pontypool?
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.
Signs you may need crack stitching
- Stepped cracking beside a window, door or corner
- Filled cracks that keep reopening along the same line
- Cracking that a surveyor or engineer has said is now stable

Crack stitching in Pontypool: questions and answers
How much will crack stitching cost in Pontypool?
Guide prices for crack stitching in Pontypool start from about £75 per metre of crack, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Pontypool?
Yes, Pontypool is covered, along with postcode districts NP4. We also cover nearby Cwmbran and Abertillery.
Is the ground in Gwent prone to subsidence?
The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. Only an investigation can say why a particular building has moved.
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.
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.
