Leigh (WN7) has around 44,000 residents and sits in Greater Manchester. Nearby places we cover include Tyldesley (2 miles), Westhoughton (4 miles) and Hindley (4 miles).
Greater Manchester has a mix of ground, with clay in some places and firmer rock in others. Parts of Greater Manchester lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Greater Manchester: red-brick terraces, mill-town stone terraces, inter-war semis and post-war estates.

Methods for brick arch repairs
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
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.
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.
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 will brick arch repairs cost in Leigh?
Guide prices for brick arch repairs in Leigh start from about £385 per arch, including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Is the ground in Greater Manchester prone to subsidence?
Greater Manchester is mostly glacial till over sandstone and mudstone, with the Lancashire coalfield beneath much of Wigan, Bolton, Salford and parts of the east. Historic mine workings, made ground and old mill sites are common. 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.
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.
