What is the ground like in Dorset?
Dorset mixes chalk downs, Oxford and Kimmeridge Clays in the vales, and the sands and gravels of the Poole basin. Clay vales can shrink and swell, and parts of the coast are known for landslip.
Ground movement here is more often linked to soils, drains and trees than to mining.
What usually causes cracking in Dorset?
In Dorset, cracking usually comes back to one of these. We rule each in or out before recommending a repair.
- Clay in parts of the area that dries out near trees in long dry spells
- Heavy stone chimneys and gables pulling away from the house
- Weathered lime mortar letting stone walls spread
- Leaking or broken drains washing fine soil out from under footings
- Garden and boundary walls leaning as tree roots and frost get to them
What kind of buildings are common here?
Stone and brick villages, Victorian villas in Bournemouth, and inter-war and post-war semis.

Is Dorset affected by subsidence?
Parts of Dorset 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.

It depends on the repair. On South West rates, mass-concrete underpinning from about £1,050 per metre of wall and a standard window or door lintel from about £770 per opening, including VAT. Your written price follows photos or a survey.
