Brick arch repairs in Oxford
Older Oxford 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.

What should you know about the ground under Oxford?
We cover Oxford and its postcode districts OX1, OX2, OX3, OX4, part of Oxfordshire, with a population of roughly 160,000. If you are just outside Oxford, we also cover Abingdon (6 miles), Didcot (10 miles) and Witney (10 miles).
Oxfordshire is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Oxfordshire: Cotswold stone villages, Victorian terraces in Oxford and Banbury, and large post-war and new-build estates around Didcot and Bicester.
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 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
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.
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.

Your brick arch repairs questions
How much will brick arch repairs cost in Oxford?
Guide prices for brick arch repairs in Oxford 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.
Do you cover Oxford?
Yes. We take enquiries from across Oxford, including OX1, OX2, OX3, OX4, and from nearby places such as Abingdon and Didcot. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Oxfordshire prone to subsidence?
Oxfordshire's vales sit on Oxford, Kimmeridge and Gault Clays, among the more shrinkage-prone clays in England, with Cotswold limestone in the north-west and chalk downs in the south. 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.
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.
