Brick arch repairs in Dorking

Flat soldier arches on Dorking houses tend to sag once a hidden bar rusts or an old window frame is replaced. Reinforcing them with stainless bars in the joints above is often enough, without taking the arch down.

How do local ground conditions affect brick arch repairs in Dorking?

Dorking (KT23, RH4) has around 18,000 residents and sits in Surrey. Neighbouring towns we cover: Leatherhead (4 miles), Redhill (7 miles) and Cobham (8 miles).

Much of Surrey sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Surrey: Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.

Signs you may need brick arch repairs

  • A vertical crack running up from the middle of the arch
  • The centre bricks of an arch sitting lower than the rest
  • A flat arch that has started to sag into a shallow curve

Which repair method suits a home in Dorking?

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

What happens when we carry out brick arch repairs in Dorking?

  1. 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.

  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. 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.

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.

Brick arch repairs in Dorking: questions and answers

How much should I budget for brick arch repairs in Dorking?

Guide prices for brick arch repairs in Dorking 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.

Why do houses in Surrey crack?

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. Only an investigation can say why a particular building has moved.

Do flat brick arches need a lintel?

Many flat soldier arches were built with a hidden steel bar or timber behind, because they have little true arch action. When repairing one, we check what is supporting it and, where needed, reinforce it with bars or add suitable support behind.

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.
