Brick arch repairs in Llangefni
Flat soldier arches on Llangefni 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.

Is Gwynedd prone to ground movement?
Llangefni is in Gwynedd and takes in postcode districts LL77. About 5,500 people live there. Neighbouring towns we cover: Bangor (8 miles), Caernarfon (8 miles) and Holyhead (14 miles).
Most of Gwynedd is on firmer ground than the clay belts of the south-east. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. What you mostly find across Gwynedd: slate and stone terraces, chapels and cottages, Victorian seaside houses and post-war estates.
What happens when we carry out brick arch repairs in Llangefni?
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.
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.
Signs you may need brick arch repairs
- Mortar falling out of the arch joints after frosty weather
- 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 Llangefni?
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
Rules for brick arch repairs in Wales
In Wales, small like-for-like repairs do not usually need approval, but work that alters or strengthens the structure needs building control under the Welsh Building Regulations, and the Party Wall etc. Act 1996 can apply to shared walls.
Brick arch repairs in Llangefni: questions and answers
How much should I budget for brick arch repairs in Llangefni?
Guide prices for brick arch repairs in Llangefni start from about £370 per arch, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Llangefni?
Yes, Llangefni is covered, along with postcode districts LL77. We also cover nearby Bangor and Caernarfon.
Why do houses in Gwynedd crack?
Gwynedd and Anglesey are mostly hard rock with glacial deposits, so clay shrinkage is uncommon. Historic slate quarrying and metal mining have left tips and workings in places. Only an investigation can say why a particular building has moved.
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.
Is a dropped brick arch dangerous?
A slightly dropped arch is not usually an immediate danger, but it is no longer carrying load as it should and tends to worsen. Loose bricks that could fall, or a fast-growing crack above, need prompt attention. Do not rely on the window frame to hold it.
