Is Dorset prone to ground movement?
Dorset mixes chalk downs, Oxford and Kimmeridge Clays in the vales, and the sands and gravels of the Poole basin. Clay vales can shrink and swell, and parts of the coast are known for landslip.
Ground movement here is more often linked to soils, drains and trees than to mining. Housing stock in Dorset: Stone and brick villages, Victorian villas in Bournemouth, and inter-war and post-war semis.

Methods for boundary and garden wall repairs
Rebuilding a leaning section
The leaning or badly cracked section is taken down, sound bricks cleaned for reuse, and the wall rebuilt on a new footing at a suitable depth. A damp-proof course and a proper coping are added, and the new work is jointed to the sound wall either side.
Best for: Sections that lean, rock or have cracked right through
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
Repointing and minor repairs
Weak mortar is raked out and the wall repointed in a mortar that suits the bricks, and damaged bricks are replaced with matching ones. Loose copings are rebedded or replaced with a design that throws water clear of both faces. This is often enough for an upright wall.
Best for: Upright walls with weathered joints, loose copings or spalled bricks

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.
Repair and rebuild
Sections are taken down, footings dug, and the wall rebuilt or repointed with a damp-proof course and coping. Reclaimed or matched bricks keep the wall consistent, and spoil and old materials are removed at the end.
Do you need approval 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.

Frequently asked questions
Does the ground around Bournemouth cause cracking?
Dorset mixes chalk downs, Oxford and Kimmeridge Clays in the vales, and the sands and gravels of the Poole basin. Clay vales can shrink and swell, and parts of the coast are known for landslip. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will boundary and garden wall repairs cost in Dorset?
On South West rates, boundary and garden wall repairs starts from about £310 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
Who is responsible for a boundary wall?
Responsibility depends on who owns the wall, which is shown in your title deeds and plans, or may be shared. A wall built on the line between two properties is often jointly owned. Check the deeds first and agree repairs with your neighbour, and in England and Wales check whether the Party Wall Act applies.
Is a leaning garden wall dangerous?
It can be, particularly a tall wall, a front wall by a pavement or one that moves when pushed. A slight lean that has not changed for years may be stable, but a wall leaning more each year should be kept clear and repaired before a storm finds it.
