Structural surveys and crack monitoring in Leigh
Ground across Leigh and Greater Manchester 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.

What is the ground like in Greater Manchester?
With roughly 44,000 people, Leigh spans postcode districts WN7 in Greater Manchester. Nearby places we cover include Tyldesley (2 miles), Westhoughton (4 miles) and Hindley (4 miles).
Parts of Greater Manchester have clay that can shrink near trees in dry spells. Parts of Greater Manchester lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Greater Manchester, most homes are red-brick terraces, mill-town stone terraces, inter-war semis and post-war estates.
Repair options we may recommend
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
What to expect when we carry out structural surveys and crack monitoring
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.
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 should I budget for structural surveys and crack monitoring in Leigh?

Why do houses in Greater Manchester crack?
Greater Manchester is mostly glacial till over sandstone and mudstone, with the Lancashire coalfield beneath much of Wigan, Bolton, Salford and parts of the east. Historic mine workings, made ground and old mill sites are common. Only an investigation can say why a particular building has moved.
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.
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.
