Methods for structural surveys and crack monitoring
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
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
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.
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 Northern Ireland

Frequently asked questions
What is the price of structural surveys and crack monitoring in Magherafelt?
Guide prices for structural surveys and crack monitoring in Magherafelt 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.

We do. Magherafelt and the surrounding area are covered, including nearby Cookstown and Ballymena. A free initial assessment from your photos is the first step.
Does the ground around Magherafelt cause cracking?
County Londonderry has basalt, older hard rock and glacial deposits, with soft river ground along the Foyle and Bann. Only an investigation can say why a particular building has moved.
Who carries out the crack monitoring?
An independent chartered structural engineer designs the monitoring and interprets the readings. We can arrange the engineer for you. We are the repair contractor, so we carry out the repair the engineer specifies once the monitoring has shown what is needed.
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.
