Methods for brick arch repairs
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
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.
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.
Symptoms that point to brick arch repairs
- Mortar falling out of the arch joints after frosty weather
- Cracks stepping out from the arch ends into the wall
- Gaps opening between arch bricks at the top or bottom edge
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 should I budget for brick arch repairs in Thorne?
Guide prices for brick arch repairs in Thorne start from about £380 per arch, including VAT, on Yorkshire and the Humber 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 Thorne?
Yes, Thorne is covered, along with postcode districts DN8. We also cover nearby Goole and Doncaster.
Why do houses in South Yorkshire crack?
South Yorkshire lies largely on the Coal Measures, with a long history of shallow and deep mining around Barnsley, Rotherham and Doncaster. Sheffield's hillside sites add retaining walls and steep ground to the mix. 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.
