Is Surrey prone to ground movement?
North Surrey sits on London Clay, the south on Weald Clay, with chalk along the North Downs and sands in the west. Large gardens with mature trees on clay make seasonal subsidence a familiar problem.
Ground movement here is more often linked to soils, drains and trees than to mining. Across Surrey, most homes are Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.
Symptoms that point to brick arch repairs
- Cracks stepping out from the arch ends into the wall
- 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

Methods for brick arch repairs
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
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
From first photo to finished repair
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.
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.
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.

Frequently asked questions
Is the ground in Surrey prone to subsidence?
North Surrey sits on London Clay, the south on Weald Clay, with chalk along the North Downs and sands in the west. Large gardens with mature trees on clay make seasonal subsidence a familiar problem. 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 Surrey?
On South East rates, brick arch repairs starts from about £450 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.
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 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.
