How we usually approach brick arch repairs
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
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 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.
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.
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.

Questions about brick arch repairs in Nailsea
How much should I budget for brick arch repairs in Nailsea?
Guide prices for brick arch repairs in Nailsea start from about £410 per arch, including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Somerset crack?
Somerset mixes Lias clays, Mercia Mudstone, limestone hills and the peat and alluvium of the Levels around Bridgwater, which can settle. The former Somerset coalfield around Radstock and Midsomer Norton left recorded workings. 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.
Can a dropped arch be repaired without rebuilding it?
Yes, if the drop is small and the brickwork is in good condition. Bars bonded into the joints above can take the load off the arch and hold it in place. If the bricks are loose or the arch has dropped badly, rebuilding is the more reliable repair.
