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
From first photo to finished repair
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.

Frequently asked questions
How much will structural surveys and crack monitoring cost in Carrickfergus?
Guide prices for structural surveys and crack monitoring in Carrickfergus start from about £440 per property, including VAT, on Northern Ireland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Carrickfergus?
Yes, Carrickfergus is covered, along with postcode districts BT38. We also cover nearby Newtownabbey and Larne.
Is the ground in County Antrim prone to subsidence?
County Antrim is largely basalt over chalk, with soft estuarine 'sleech' along Belfast Lough that is notorious for settlement. Historic salt mining is recorded near Carrickfergus. Only an investigation can say why a particular building has moved.
What is a tell-tale on a crack?
A tell-tale is a small gauge fixed across a crack, with two overlapping plates marked in millimetres. As the crack opens, closes or shears, the plates move against each other and the reading changes. It gives a simple, repeatable record that anyone can check between visits.
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.
