Brick arch repairs in Maidenhead
Flat soldier arches on Maidenhead 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 Berkshire prone to ground movement?
Maidenhead is in Berkshire and takes in postcode districts SL6. About 70,000 people live there. We also take enquiries from nearby Marlow (4 miles), Slough (5 miles) and High Wycombe (7 miles).
Much of Berkshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Berkshire: Victorian and Edwardian terraces in Reading and Windsor, 1930s semis, and large post-war new-town estates around Bracknell.

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.
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.
Is it time for brick arch repairs? Common signs

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
How much should I budget for brick arch repairs in Maidenhead?
Guide prices for brick arch repairs in Maidenhead start from about £450 per arch, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Berkshire crack?
East Berkshire is largely London Clay with Thames terrace gravels along the river, while the west rises onto chalk downland. Houses on the clay near Slough, Windsor and Bracknell are the ones most exposed to shrink-swell movement. 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.
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.
