What should you know about the ground under Caterham?
Caterham, Surrey: about 21,000 residents across postcode districts CR3, CR6. Nearby places we cover include Redhill (5 miles), Croydon (5 miles) and Banstead (6 miles).
Much of Surrey 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 Surrey: Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.

Repair options we may recommend
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
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.

Your crack stitching questions
What is the price of crack stitching in Caterham?
Guide prices for crack stitching in Caterham 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 carry out crack stitching in Caterham?
Yes. We take enquiries from across Caterham, including CR3, CR6, and from nearby places such as Redhill and Croydon. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Caterham cause cracking?
North Surrey sits on London Clay, the south on Weald Clay, with chalk along the North Downs and sands in the west. Large gardens with mature trees on clay make seasonal subsidence a familiar problem. Only an investigation can say why a particular building has moved.
Does crack stitching stop a wall moving?
No, crack stitching reconnects cracked masonry but does not stop the movement that caused it. If the ground is still shrinking, a drain is still leaking or ties are still rusting, a stitched wall can crack again nearby. The cause has to be identified and dealt with first.
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.
