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
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
What to expect when we carry out structural crack repairs
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.

Your structural crack repairs questions
How much will structural crack repairs cost in Melksham?
Guide prices for structural crack repairs in Melksham start from about £80 per metre of crack, including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Melksham?
Yes. We take enquiries from across Melksham, including SN12, and from nearby places such as Trowbridge and Chippenham. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Wiltshire prone to subsidence?
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. 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.
When is a crack in a wall structural?
A crack is more likely to be structural when it is wider than about 5 mm, tapers, passes through the whole wall or keeps growing. BRE Digest 251 treats damage up to about 5 mm as aesthetic and over 25 mm as a stability concern. Width is a guide, not a diagnosis.
