Structural surveys and crack monitoring in Leighton Buzzard
Ground across Leighton Buzzard and Bedfordshire varies, and on clay the same crack can open in summer and close in winter. Readings taken in both seasons show the engineer which pattern applies before anyone decides on a repair.

Leighton Buzzard, Bedfordshire: about 43,000 residents across postcode districts LU7. Nearby places we cover include Dunstable (6 miles), Bletchley (6 miles) and Milton Keynes (10 miles).
Shrinkable clay is widespread in Bedfordshire. Ground movement here is more often linked to soils, drains and trees than to mining.

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
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.
Your structural surveys and crack monitoring questions

Why do houses in Bedfordshire crack?
Much of Bedfordshire sits on Oxford Clay and Gault Clay, with chalk rising towards the Chilterns in the south. The clay vales shrink in dry summers and swell in wet winters, which is why seasonal cracking is common around Bedford. 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.
How long does crack monitoring take?
Monitoring normally runs for 6 to 12 months, because readings need to cover both the dry and wet seasons on clay soils. Shorter periods can be enough where the cause is clearly non-seasonal, such as a drain leak that has been repaired. The engineer decides when there is enough evidence.
