Is Surrey prone to ground movement?
We cover Egham and its postcode districts TW20, part of Surrey, with a population of roughly 30,000. Neighbouring towns we cover: Staines-upon-Thames (2 miles), Chertsey (4 miles) and Ashford (4 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. What you mostly find across Surrey: Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.

Methods for brick arch repairs
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
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.
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.
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
- The centre bricks of an arch sitting lower than the rest
- 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 will brick arch repairs cost in Egham?

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. 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.
