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 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

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.

Your brick arch repairs questions

How much will brick arch repairs cost in Holywood?

Guide prices for brick arch repairs in Holywood start from about £350 per arch, 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.

Is the ground in County Down prone to subsidence?

County Down is mostly drumlin till over older rock and granite in the Mournes, with soft estuarine ground around Belfast Lough and Strangford. Only an investigation can say why a particular building has moved.

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.

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.
