Brick arch repairs in Ashford
Older Ashford houses often carry their window and door heads on brick arches built without any steel at all. When the centre bricks slip, the arch either needs reinforcing in place or rebuilding over a timber former.

How do local ground conditions affect brick arch repairs in Ashford?
Ashford (TW15, TW16, TW18) has around 27,000 residents and sits in Surrey. If you are just outside Ashford, we also cover Staines-upon-Thames (2 miles), Sunbury-on-Thames (3 miles) and Chertsey (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. Across Surrey, most homes are Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.

Repair options we may recommend
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 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
What to expect when we carry out brick arch repairs
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.
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.
Your brick arch repairs questions
How much will brick arch repairs cost in Ashford?

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.
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.
