Why does the ground in Berkshire matter for crack stitching?

Slough (SL1, SL2, SL3) has around 160,000 residents and sits in Berkshire. We also take enquiries from nearby Maidenhead (5 miles), Gerrards Cross (6 miles) and Egham (6 miles).

Much of Berkshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Berkshire: Victorian and Edwardian terraces in Reading and Windsor, 1930s semis, and large post-war new-town estates around Bracknell.

Symptoms that point to crack stitching

  • Filled cracks that keep reopening along the same line
  • A crack you can fit a coin into, running through bricks and mortar
  • Cracking that a surveyor or engineer has said is now stable

Methods for crack stitching

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

From first photo to finished repair

  1. 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.

  2. 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.

  3. 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.

Frequently asked questions

How much will crack stitching cost in Slough?

Guide prices for crack stitching in Slough start from about £90 per metre of crack, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you cover Slough?

Yes, Slough is covered, along with postcode districts SL1, SL2, SL3. We also cover nearby Maidenhead and Gerrards Cross.

Is the ground in Berkshire prone to subsidence?

East Berkshire is largely London Clay with Thames terrace gravels along the river, while the west rises onto chalk downland. Houses on the clay near Slough, Windsor and Bracknell are the ones most exposed to shrink-swell movement. 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.

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.
