Brick arch repairs in Colchester
Before repairing a brick arch at a Colchester 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.

Is Essex prone to ground movement?
Colchester (CO1, CO2, CO3, CO4) has around 130,000 residents and sits in Essex. If you are just outside Colchester, we also cover Sudbury (13 miles), Clacton-on-Sea (13 miles) and Witham (13 miles).
Shrinkable clay is widespread in Essex. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Essex: Victorian terraces, 1930s semis and bungalows, and large post-war new-town estates in Basildon and Harlow.

Which repair method suits a home in Colchester?
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
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 happens when we carry out brick arch repairs in Colchester?
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.
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
- Cracks stepping out from the arch ends into the wall
- Mortar falling out of the arch joints after frosty weather
- A vertical crack running up from the middle of the arch
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 Colchester: questions and answers
What is the price of brick arch repairs in Colchester?
Guide prices for brick arch repairs in Colchester start from about £420 per arch, including VAT, on East of England 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 Colchester?
We do. Colchester and the surrounding area are covered, including nearby Sudbury and Clacton-on-Sea. A free initial assessment from your photos is the first step.
Does the ground around Colchester cause cracking?
London Clay covers much of south and central Essex and boulder clay much of the north, making it one of the counties most affected by clay shrinkage in dry summers. Street and garden trees close to houses add to the risk. Only an investigation can say why a particular building has moved.
What is a former in arch building?
A former, sometimes called a centre, is a temporary timber frame cut to the exact shape of the arch. It supports the bricks while the arch is laid and the mortar cures, and is removed once the arch can carry itself.
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.
