Brick arch repairs in Glasgow
If you live in Glasgow and are looking at brick arch repairs, the first question is why the wall moved. Most of Glasgow is on firmer ground than the clay belts of the south-east; historic coal workings are recorded beneath parts of Glasgow, and a coal mining search is worth checking where movement is unexplained.

Why does the ground in Glasgow matter for brick arch repairs?
Glasgow is underlain by the Central Coalfield, with shallow historic coal and ironstone workings recorded across much of the city, beneath glacial till and river deposits along the Clyde.
Historic coal workings are recorded beneath parts of Glasgow, and a coal mining search is worth checking where movement is unexplained. Across Glasgow, most homes are red and blond sandstone tenements, Victorian villas, inter-war cottage flats and post-war estates.

How we usually approach brick arch repairs
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
Lime mortar repairs
On older houses built in soft brick and lime, the arch is rebuilt or repointed in a lime mortar matched to the original. Lime lets moisture escape and moves slightly with the wall, so it protects the bricks rather than forcing damage into them, as hard cement mortar can.
Best for: Pre-1919 houses and soft historic brick
What happens during brick arch repairs, step by step?
Look at the arch closely
Straight-on photos of the arch and the wall either side show us how far it has dropped, whether the bricks are sound and whether the cause seems to be the arch itself or the wall around it.
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.
Strike the former and point
Once the mortar has cured enough, the former and props are removed. Joints are finished to match the surrounding wall, and any cracks running from the arch into the wall are repaired at the same visit.
What to look for before calling about brick arch repairs
- A vertical crack running up from the middle of the arch
- Gaps opening between arch bricks at the top or bottom edge
- A flat arch that has started to sag into a shallow curve
- Mortar falling out of the arch joints after frosty weather
Do you need approval 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.
Questions about brick arch repairs in Glasgow
Does the ground around Glasgow cause cracking?
Glasgow is underlain by the Central Coalfield, with shallow historic coal and ironstone workings recorded across much of the city, beneath glacial till and river deposits along the Clyde. Historic coal workings are recorded beneath parts of Glasgow, 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 Glasgow?
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.
What is a former in arch building?
A former, sometimes called a centre, is a temporary timber frame cut to the exact shape of the arch. It supports the bricks while the arch is laid and the mortar cures, and is removed once the arch can carry itself.
