What should you know about the ground under Wiltshire?
Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham.
Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Wiltshire: Stone cottages, railway terraces in Swindon, and large post-war and new-build estates.
Repair options we may recommend
Filling and repointing
For hairline and narrow cracks that have stopped moving, the crack line is raked out and repointed in mortar matched to the original for strength, colour and texture. Inside, plaster cracks are cut out, filled with a flexible filler and redecorated.
Best for: Cracks up to about 5 mm that are no longer moving
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

Your structural crack repairs questions
Does the ground around Swindon cause cracking?
Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will structural crack repairs cost in Wiltshire?
On South West rates, structural crack repairs starts from about £80 per metre of crack, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Should I tell my insurer about cracks in my house?
Yes, if you think the cracks could come from subsidence or heave, tell your insurer before any permanent repair, because repairing first can make a claim harder to prove. Cracks from normal shrinkage or ageing are not usually covered, and the insurer decides which applies.
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.
