Why does the ground in Kent matter for brick arch repairs?
With roughly 51,000 people, Dartford spans postcode districts DA1 in Kent. We also take enquiries from nearby Bexley (3 miles), Swanley (4 miles) and Swanscombe (4 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. Across Kent, most homes are Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.

Methods for brick arch repairs
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 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
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.
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.
Symptoms that point to brick arch repairs
- A vertical crack running up from the middle of the arch
- Cracks stepping out from the arch ends into the wall
- A flat arch that has started to sag into a shallow curve
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 Dartford?
Guide prices for brick arch repairs in Dartford 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 Dartford?
We do. Dartford and the surrounding area are covered, including nearby Bexley 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.
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.
Why has the middle of my brick arch dropped?
The centre of an arch usually drops because the bricks have lost their wedge, either because the wall at the sides has moved or the mortar has worn away. A rotting timber hidden behind the arch is another common cause. The keystone slipping is the visible result.
