Brick arch repairs in Sevenoaks
Rebuilding an arch in Sevenoaks is a precise job: a former cut to the exact curve, tight joints and a keystone set at the right height. Done well, the new arch looks as though it was always there.

Is Kent prone to ground movement?
Postcode districts TN13 cover Sevenoaks, a Kent town of about 30,000 people. We also take enquiries from nearby Tonbridge (6 miles), Swanley (9 miles) and Bromley (10 miles).
Kent is one of the parts of the UK where clay soils are most likely to move with the seasons. Parts of Kent lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.
Methods for 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
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.
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.
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.
Symptoms that point to brick arch repairs
- A vertical crack running up from the middle of the arch
- Mortar falling out of the arch joints after frosty weather
- Gaps opening between arch bricks at the top or bottom edge

Rules 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
How much should I budget for brick arch repairs in Sevenoaks?
Guide prices for brick arch repairs in Sevenoaks start from about £450 per arch, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Sevenoaks?
We do. Sevenoaks and the surrounding area are covered, including nearby Tonbridge and Swanley. A free initial assessment from your photos is the first step.
Why do houses in Kent crack?
North Kent sits on London Clay, central Kent on Gault and Weald Clays and the Downs on chalk, so shrinkable clay is widespread. East Kent around Deal and Dover had a small deep coalfield, worked until the late 1980s. 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 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.
