Methods for structural crack repairs
Rebuilding a cracked section
Where bricks have split or the wall has moved out of line, the damaged area is taken down and rebuilt, bonded into sound masonry on either side. Reclaimed or matched bricks keep the repair discreet, with temporary support used where needed.
Best for: Badly displaced or broken brickwork
Crack stitching with helical bars
Stainless steel helical bars are grouted into slots cut along the bed joints, bridging the crack so the masonry works as one piece again. It is the standard repair for wider stepped and vertical cracks once whatever caused them has stopped.
Best for: Stable cracks wider than about 5 mm, or ones that keep reopening
From first photo to finished repair
Survey and record
On site we measure the width along the crack, note its pattern and check nearby drains, trees and openings. If the cause is unclear, gauges can be fixed across it and read over several months.
Deal with the cause
Leaking drains, failed ties, a sagging lintel or ground movement are put right first, sometimes through an insurance claim. Repairing a crack before its cause is fixed usually means paying for the same job twice.
Repair and make good
Cracks are stitched, repointed or rebuilt as specified, with mortar matched to the existing wall. Internal crack lines are filled and redecorated where included, and you get a written note of what was done.
Symptoms that point to structural crack repairs
- A crack noticeably wider at the top than the bottom, or the reverse
- Daylight or a draught coming through a crack in an outside wall
- Diagonal cracks running from the corners of windows and doors
Rules for structural crack repairs 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 structural crack repairs cost in Slough?
Guide prices for structural crack repairs 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?
We do. Slough and the surrounding area are covered, including nearby Maidenhead and Gerrards Cross. A free initial assessment from your photos is the first step.
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 I just fill a crack and paint over it?
You can fill a fine crack that is not moving, and for many hairline cracks that is the right repair. Filling a crack that is still opening hides the evidence, and it will usually come back. If a filled crack returns within a year or two, have it assessed.
What do stepped cracks in brickwork mean?
Stepped cracks usually mean part of the wall has moved and the weakest path, the mortar joints, has given way. They are common with subsidence and around openings. A thin stepped crack unchanged for years is often cosmetic, while a wide or tapered one should be looked at.
