Brick arch repairs in Berkhamsted
A dropped keystone over a front door is a familiar sight on older streets, in Berkhamsted and beyond, and it rarely fixes itself. We look at whether the arch bricks are sound and whether the wall either side has moved, then recommend the lighter repair where it will work.

How do local ground conditions affect brick arch repairs in Berkhamsted?

Much of Hertfordshire 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. Across Hertfordshire, most homes are garden-city houses in Letchworth and Welwyn, 1930s semis, Victorian terraces and post-war new-town estates.

Methods for brick arch repairs
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
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.
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.
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.
Frequently asked questions
What is the price of brick arch repairs in Berkhamsted?
Guide prices for brick arch repairs in Berkhamsted 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 Berkhamsted?
We do. Berkhamsted and the surrounding area are covered, including nearby Chesham and Hemel Hempstead. A free initial assessment from your photos is the first step.
Does the ground around Berkhamsted cause cracking?
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.
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.
Can you match the original bricks?
Usually, because most arches are rebuilt with their own cleaned bricks, which is the best match of all. Damaged bricks are replaced with reclaimed or new bricks chosen for size, colour and texture, and the mortar is matched to the surrounding joints.
