What should you know about the ground under Yeovil?
Yeovil is in Somerset and takes in postcode districts BA20, BA21. About 50,000 people live there. Neighbouring towns we cover: Dorchester (18 miles), Bridgwater (21 miles) and Taunton (21 miles).
Parts of Somerset have clay that can shrink near trees in dry spells. Parts of Somerset lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Somerset: Bath stone Georgian terraces, Victorian houses in Taunton and Weston-super-Mare, and post-war estates.

Methods for structural surveys and crack monitoring
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
Level monitoring
Survey points are fixed around the building and their heights measured against a stable datum on each visit. This shows whether one part of the house is dropping or rising compared with the rest, which crack widths alone cannot reveal.
Best for: Suspected subsidence or heave across a whole house
From first photo to finished repair
Engineer’s inspection
We can arrange an independent chartered structural engineer to inspect. They record the damage, assess likely causes and recommend whether monitoring, drain surveys or trial pits are needed before any repair decision.
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.
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 should I budget for structural surveys and crack monitoring in Yeovil?
Guide prices for structural surveys and crack monitoring in Yeovil 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.
Can you survey a property in Yeovil?
We do. Yeovil and the surrounding area are covered, including nearby Dorchester and Bridgwater. A free initial assessment from your photos is the first step.
Why do houses in Somerset crack?
Somerset mixes Lias clays, Mercia Mudstone, limestone hills and the peat and alluvium of the Levels around Bridgwater, which can settle. The former Somerset coalfield around Radstock and Midsomer Norton left recorded workings. Only an investigation can say why a particular building has moved.
Can I monitor cracks myself?
You can keep a useful record by photographing cracks with a ruler and pencilling dated marks at their ends. That helps an engineer, but it does not replace measured monitoring, which insurers and lenders usually expect. Do not fill or decorate over cracks while monitoring.
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.
