How we usually approach boundary and garden wall repairs
New piers and movement joints
Brick piers are built at intervals along the wall, bonded in or tied with stainless fixings, to stiffen it against wind and lean. Vertical movement joints are cut where a long run keeps cracking. Gate piers are rebuilt larger and on deeper footings where they carry heavy gates.
Best for: Long walls with regular cracks, or weak gate piers
Dealing with roots and soil loading
Soil banked against the wall is dug back. Where roots are the cause, the wall can be rebuilt with a lintel bridging the root zone, or realigned to give the tree room. Decisions about the tree are made with its owner and, where needed, a tree specialist.
Best for: Walls lifted by roots or pushed over by banked soil
What happens during boundary and garden wall repairs, step by step?
Site assessment
On site we check the lean with a level, look at the footing where it can be seen, note the bricks and mortar, and check for trees, soil loading and gate loads. If the wall turns out to be retaining soil, we treat it as a retaining wall.
Written quote
You receive a no-obligation written quote that separates repointing, rebuilt sections, new piers and copings, so you or your neighbour can see each part. It becomes a fixed price in writing once the repair is specified.

Rules for boundary and garden wall 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.
Questions about boundary and garden wall repairs in Welwyn Garden City
How much should I budget for boundary and garden wall repairs in Welwyn Garden City?
Guide prices for boundary and garden wall repairs in Welwyn Garden City start from about £315 per wall, 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.
Does the Party Wall Act apply to garden walls?
It can, in England and Wales. A boundary wall that stands astride the line of junction, used by both owners, can be a party fence wall under the Party Wall etc. Act 1996, and some work to it needs notice. A wall wholly on one side is not covered in the same way. Scotland and Northern Ireland have no Party Wall Act.
Do I need permission to rebuild a front wall?
Usually not for a like-for-like rebuild. Building a front wall next to a road higher than the permitted height, or work in a conservation area or to a listed building, can need planning consent. Check with your council before changing a wall’s height or appearance.
