Brick arch repairs in Rickmansworth
Flat soldier arches on Rickmansworth 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 Hertfordshire prone to ground movement?
Rickmansworth (HA6, WD3, WD18) has around 25,000 residents and sits in Hertfordshire. Neighbouring towns we cover: Watford (4 miles), Gerrards Cross (5 miles) and Amersham (6 miles).
Shrinkable clay is widespread in Hertfordshire. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Hertfordshire: garden-city houses in Letchworth and Welwyn, 1930s semis, Victorian terraces and post-war new-town estates.

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
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
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
How much should I budget for brick arch repairs in Rickmansworth?
Guide prices for brick arch repairs in Rickmansworth 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.

Why do houses in Hertfordshire crack?
South Hertfordshire around Watford, Borehamwood and Potters Bar is London Clay, while the north and west are chalk with clay-with-flints and the east has boulder clay. The clay areas are prone to seasonal subsidence near trees. Only an investigation can say why a particular building has moved.
Do flat brick arches need a lintel?
Many flat soldier arches were built with a hidden steel bar or timber behind, because they have little true arch action. When repairing one, we check what is supporting it and, where needed, reinforce it with bars or add suitable support behind.
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.
