Brick arch repairs in Dunstable
Older Dunstable 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.

Is Bedfordshire prone to ground movement?
We cover Dunstable and its postcode districts LU6, part of Bedfordshire, with a population of roughly 52,000. Nearby, we also cover Luton (5 miles), Leighton Buzzard (6 miles) and Harpenden (9 miles).
Much of Bedfordshire 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 Bedfordshire: Victorian terraces in Bedford and Luton, large inter-war and post-war estates, and newer estates on former clay pits and brickfields.
What happens when we carry out brick arch repairs in Dunstable?
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.
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.
Signs you may need brick arch repairs

- A flat arch that has started to sag into a shallow curve

Which repair method suits a home in Dunstable?
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
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
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 Dunstable: questions and answers

Is the ground in Bedfordshire prone to subsidence?
Much of Bedfordshire sits on Oxford Clay and Gault Clay, with chalk rising towards the Chilterns in the south. The clay vales shrink in dry summers and swell in wet winters, which is why seasonal cracking is common around Bedford. Only an investigation can say why a particular building has moved.
Can a dropped arch be repaired without rebuilding it?
Yes, if the drop is small and the brickwork is in good condition. Bars bonded into the joints above can take the load off the arch and hold it in place. If the bricks are loose or the arch has dropped badly, rebuilding is the more reliable repair.
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.
