Brick arch repairs in Lancashire

Homes in Lancashire are mostly stone and brick mill terraces. That matters for brick arch repairs: footings, wall construction and mortar all vary with the age of the building. Parts of Lancashire have clay that can shrink near trees in dry spells.

Is Lancashire prone to ground movement?

Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns.

Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Lancashire, most homes are stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.

Which repair method suits a home in Lancashire?

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

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 happens when we carry out brick arch repairs in Lancashire?

  1. 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.

  2. 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.

  3. 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.

Do you need approval for brick arch repairs in England?

Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.

Brick arch repairs in Lancashire: questions and answers

Why do houses in Lancashire crack?

Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will brick arch repairs cost in Lancashire?

On North West rates, brick arch repairs starts from about £385 per arch, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

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.

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.
