What is the ground like in Dorset?
Dorchester (DT1) has around 17,000 residents and sits in Dorset. If you are just outside Dorchester, we also cover Weymouth (7 miles), Yeovil (18 miles) and Poole (20 miles).
Dorset has a mix of ground, with clay in some places and firmer rock in others. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Dorset: stone and brick villages, Victorian villas in Bournemouth, and inter-war and post-war semis.
From first photo to finished repair
Free initial assessment
Send photos of the cracks with something for scale and tell us when they appeared. We give a free view on whether an engineer’s inspection is worthwhile, and whether your insurer should be told first.
Install monitoring points
Tell-tales, measuring studs or level points are fixed at the locations the engineer chooses. A base reading is taken on the first visit, so every later reading can be compared against it.
Seasonal readings
Readings are taken at intervals across the seasons, typically including late summer when clay is driest and late winter when it is wettest. The engineer checks each set against the base reading and decides whether more visits are needed.
Symptoms that point to structural surveys and crack monitoring
- A crack you are unsure is old or new
- Cracks that seem wider after a hot, dry summer
- Doors and windows sticking at some times of year only

Methods for structural surveys and crack monitoring
Engineer’s structural inspection and report
A chartered structural engineer visits, records the cracks, checks the walls, floors, drains and nearby trees, and writes a report on the likely cause and next steps. It may recommend monitoring, investigations such as trial pits, or a repair specification.
Best for: A first expert opinion on any significant cracking
Tell-tales and crack-width monitoring
Gauges are fixed across key cracks and read at set intervals, or reference studs are measured with callipers to a fraction of a millimetre. The readings show whether each crack is widening, closing or stable, and whether any change follows the seasons.
Best for: Tracking individual cracks over the seasons
Rules for structural surveys and crack monitoring 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 surveys and crack monitoring cost in Dorchester?
Guide prices for structural surveys and crack monitoring in Dorchester start from about £515 per property, 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 Dorchester?
Yes, Dorchester is covered, along with postcode districts DT1. We also cover nearby Weymouth and Yeovil.
Is the ground in Dorset prone to subsidence?
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. Only an investigation can say why a particular building has moved.
Who carries out the crack monitoring?
An independent chartered structural engineer designs the monitoring and interprets the readings. We can arrange the engineer for you. We are the repair contractor, so we carry out the repair the engineer specifies once the monitoring has shown what is needed.
What do BRE crack categories mean?
BRE Digest 251 groups damage by typical crack width. Category 0 is under 0.1 mm, 1 up to 1 mm, 2 up to 5 mm, 3 from 5 to 15 mm or several of about 3 mm, 4 from 15 to 25 mm, and 5 usually over 25 mm. It is a guide to severity, not a diagnosis of cause.
