Brick arch repairs in Lanarkshire

Across Lanarkshire, requests for brick arch repairs usually begin with a crack someone has noticed getting wider. Clay shrinkage is less of a concern in Lanarkshire, so other causes such as drains, poor footings or older walls are checked first. A repair only lasts if the reason for the movement has stopped.

How do local ground conditions affect brick arch repairs in Lanarkshire?

Lanarkshire lies on the Central Coalfield, mined intensively in the past around Hamilton, Motherwell, Airdrie and Coatbridge, so recorded workings are common beneath towns.

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

Repair options we may recommend

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 both faces

Where the arch shows inside as well as outside, or a rotten timber behind it has also failed, both faces are rebuilt. The inner timber is replaced with a suitable lintel, and the outer arch is reformed in front. The two are worked in sequence so the wall is supported throughout.

Best for: Arches with a failed timber or inner face

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

What to expect when we carry out brick arch repairs

  1. 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.

  2. 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.

  3. 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.

Your brick arch repairs questions

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. Historic coal workings are recorded beneath parts of Lanarkshire, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.

How much will brick arch repairs cost in Lanarkshire?

On Scotland rates, brick arch repairs starts from about £380 per arch, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

Is a dropped brick arch dangerous?

A slightly dropped arch is not usually an immediate danger, but it is no longer carrying load as it should and tends to worsen. Loose bricks that could fall, or a fast-growing crack above, need prompt attention. Do not rely on the window frame to hold it.

Do flat brick arches need a lintel?

Many flat soldier arches were built with a hidden steel bar or timber behind, because they have little true arch action. When repairing one, we check what is supporting it and, where needed, reinforce it with bars or add suitable support behind.

Can you match the original bricks?

Usually, because most arches are rebuilt with their own cleaned bricks, which is the best match of all. Damaged bricks are replaced with reclaimed or new bricks chosen for size, colour and texture, and the mortar is matched to the surrounding joints.
