Historic coal workings are recorded beneath parts of Lanarkshire, and a coal mining search is worth checking where movement is unexplained. What you mostly find across Lanarkshire: miners' rows, sandstone tenements, inter-war council houses and new-town estates in East Kilbride and Cumbernauld.

Methods for brick arch repairs
Reinforcing a sound arch
Where the arch has only dropped slightly and the bricks are sound, stainless helical bars are bonded into the bed joints just above it, extending well into the wall on each side. The bars turn the courses above into a reinforced band of masonry, so the arch no longer has to carry the full load. Joints are repointed to match.
Best for: Slightly dropped or cracked arches with sound bricks
Rebuilding over a former
A timber former is cut to the arch profile and propped under the opening. The old arch is carefully taken down, bricks cleaned for reuse, and the arch rebuilt over the former with tight joints and a properly set keystone. The former stays until the mortar is strong enough to carry the load.
Best for: Badly dropped arches or ones with loose voussoirs
From first photo to finished repair
Choose reinforce or rebuild
We recommend reinforcement where the arch is sound and only slightly displaced, and a rebuild where it has dropped badly or bricks are loose. If the wall beside the opening is moving, that is dealt with first.
Support the opening
Props carry the brickwork above, and for a rebuild a former is made to the exact profile of the arch. The window or door frame is protected so it is not asked to carry any load.
Repair the arch
Bars are bonded into the joints above a sound arch, or the arch is taken down and relaid over the former using the original bricks where possible, with matched replacements for any that are damaged.
Rules for brick arch repairs in Scotland
In Scotland, small repairs often do not need a building warrant, but structural alterations and strengthening generally do. Check with the council’s building standards service if unsure; there is no Party Wall Act in Scotland.
Frequently asked questions
How much should I budget for brick arch repairs in Blantyre?
Guide prices for brick arch repairs in Blantyre start from about £380 per arch, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Blantyre?
Yes, Blantyre is covered, along with postcode districts G71, G72, ML3. We also cover nearby Cambuslang and Hamilton.
Why do houses in Lanarkshire crack?
Lanarkshire lies on the Central Coalfield, mined intensively in the past around Hamilton, Motherwell, Airdrie and Coatbridge, so recorded workings are common beneath towns. Only an investigation can say why a particular building has moved.
Should a brick arch be repaired with lime mortar?
On older houses built with soft bricks and lime, yes, in most cases. Lime mortar lets the wall breathe and is weaker than the brick, so any movement or frost damage happens in the joints rather than the bricks. Modern hard brickwork can take a cement-based mortar.
Why has the middle of my brick arch dropped?
The centre of an arch usually drops because the bricks have lost their wedge, either because the wall at the sides has moved or the mortar has worn away. A rotting timber hidden behind the arch is another common cause. The keystone slipping is the visible result.
