Brick arch repairs in Chelmsford
Flat soldier arches on Chelmsford 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.

What is the ground like in Essex?
Chelmsford is in Essex and takes in postcode districts CM1. About 110,000 people live there. Nearby, we also cover Billericay (8 miles), Witham (9 miles) and Maldon (9 miles).
Essex is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Essex: Victorian terraces, 1930s semis and bungalows, and large post-war new-town estates in Basildon and Harlow.
Repair options we may recommend
Rebuilding both faces
Where the arch shows inside as well as outside, or a rotten timber behind it has also failed, both faces are rebuilt. The inner timber is replaced with a suitable lintel, and the outer arch is reformed in front. The two are worked in sequence so the wall is supported throughout.
Best for: Arches with a failed timber or inner face
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.
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.

Your brick arch repairs questions
How much should I budget for brick arch repairs in Chelmsford?
Guide prices for brick arch repairs in Chelmsford 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.
Can you survey a property in Chelmsford?
Yes, Chelmsford is covered, along with postcode districts CM1. We also cover nearby Billericay and Witham.
Why do houses in Essex crack?
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.
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.
