Is Wiltshire prone to ground movement?

Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham.

Ground movement here is more often linked to soils, drains and trees than to mining. Housing stock in Wiltshire: Stone cottages, railway terraces in Swindon, and large post-war and new-build estates.

What happens during brick arch repairs, step by step?

  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. 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. 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

  • The centre bricks of an arch sitting lower than the rest
  • Mortar falling out of the arch joints after frosty weather
  • A vertical crack running up from the middle of the arch
  • Gaps opening between arch bricks at the top or bottom edge

How we usually approach brick arch repairs

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

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

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.

Questions about brick arch repairs in Wiltshire

Is the ground in Wiltshire prone to subsidence?

Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.

How much will brick arch repairs cost in Wiltshire?

On South West rates, brick arch repairs starts from about £410 per arch, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

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.
