What should you know about the ground under Gwynedd?
Gwynedd and Anglesey are mostly hard rock with glacial deposits, so clay shrinkage is uncommon. Historic slate quarrying and metal mining have left tips and workings in places.
Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Gwynedd, most homes are slate and stone terraces, chapels and cottages, Victorian seaside houses and post-war estates.
Repair options we may recommend
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
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
What to expect when we carry out boundary and garden wall repairs
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.
Neighbour and notices
Where the wall is shared or on the line of junction in England and Wales, the Party Wall etc. Act 1996 may require notice before work starts. We can explain what is likely to be needed, and work is agreed with neighbours first.
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.

Your boundary and garden wall repairs questions
Does the ground around Bangor cause cracking?
Gwynedd and Anglesey are mostly hard rock with glacial deposits, so clay shrinkage is uncommon. Historic slate quarrying and metal mining have left tips and workings in places. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Only an investigation on site can say why a particular building has moved.
How much will boundary and garden wall repairs cost in Gwynedd?
On Wales rates, boundary and garden wall repairs starts from about £275 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
Does home insurance cover a fallen garden wall?
Sometimes, but many policies exclude garden walls or cover them only for certain events, such as vehicle impact or storm. Frost, wear and tree root damage are usually excluded. If a vehicle caused the damage, the driver’s insurer may pay. Check your policy and tell your insurer before permanent repairs start.
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.
