Repair options we may recommend
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
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
What to expect when we carry out structural surveys and crack monitoring
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.
Repair or close
If the readings show the house is stable, the engineer specifies the repair and we confirm a fixed price in writing. If movement continues, the cause is investigated further before a foundation repair is designed.

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.
Your structural surveys and crack monitoring questions
How much will structural surveys and crack monitoring cost in Thorne?
Guide prices for structural surveys and crack monitoring in Thorne start from about £475 per property, including VAT, on Yorkshire and the Humber rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Thorne?
We do. Thorne and the surrounding area are covered, including nearby Goole and Doncaster. A free initial assessment from your photos is the first step.
Is the ground in South Yorkshire prone to subsidence?
South Yorkshire lies largely on the Coal Measures, with a long history of shallow and deep mining around Barnsley, Rotherham and Doncaster. Sheffield's hillside sites add retaining walls and steep ground to the mix. Only an investigation can say why a particular building has moved.
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.
When should I get a structural engineer’s report?
It is worth getting one when cracks are wider than a few millimetres, tapered, getting worse, or accompanied by sticking doors and sloping floors. A mortgage valuer or insurer asking for one is another clear trigger. Fine, stable hairline cracks often do not need one.
