Brick arch repairs in Portishead
Before repairing a brick arch at a Portishead property, we check what sits behind it. A rotting timber lintel on the inner face is a frequent hidden cause, and fixing only the visible arch would leave the real problem in place.

Repair options we may recommend
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
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
What to expect when we carry out brick arch repairs
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.
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
What is the price of brick arch repairs in Portishead?
Guide prices for brick arch repairs in Portishead start from about £410 per arch, including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out brick arch repairs in Portishead?
We do. Portishead and the surrounding area are covered, including nearby Nailsea and Clevedon. A free initial assessment from your photos is the first step.
Does the ground around Portishead cause cracking?
Somerset mixes Lias clays, Mercia Mudstone, limestone hills and the peat and alluvium of the Levels around Bridgwater, which can settle. The former Somerset coalfield around Radstock and Midsomer Norton left recorded workings. Only an investigation can say why a particular building has moved.
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.
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.
