What is the ground like in 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.
What usually causes cracking in Wiltshire?
In Wiltshire, cracking usually comes back to one of these. We rule each in or out before recommending a repair.
- Pockets of shrinkable clay, mainly where large trees grow close to the house
- Heavy stone chimneys and gables pulling away from the house
- Solid stone walls bulging where the rubble core has loosened
- Garden and boundary walls leaning as tree roots and frost get to them
- Leaking or broken drains washing fine soil out from under footings
What kind of buildings are common here?
Stone cottages, railway terraces in Swindon, and large post-war and new-build estates.

Questions about structural repairs in Wiltshire
Do you cover the whole of Wiltshire?
Yes. We take enquiries from across Wiltshire, including Swindon, Salisbury, Trowbridge and Chippenham. A free initial assessment from your photos is the first step.
Is Wiltshire affected by subsidence?
Parts of Wiltshire have clay that can shrink near trees in dry spells. Ground movement here is more often linked to soils, drains and trees than to mining. Whether a particular building has moved, and why, needs an investigation on site.
How much do structural repairs cost in Wiltshire?
It depends on the repair. On South West rates, a standard window or door lintel from about £770 per opening and wall tie replacement on a semi-detached house from about £2,600 per house, including VAT. Your written price follows photos or a survey.
What should I send for a free assessment in Wiltshire?
Photos of each crack inside and out with a coin or tape for scale, a wider shot showing where it is on the building, your postcode in Wiltshire, and when you first noticed it. If an insurer is involved, include the claim reference.
