What is the ground like in Gwynedd?
Postcode districts LL77 cover Llangefni, a Gwynedd town of about 5,500 people. Nearby places we cover include Bangor (8 miles), Caernarfon (8 miles) and Holyhead (14 miles).
Shrinkable clay is less common in Gwynedd than in south-east England. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Typical buildings in Gwynedd: Slate and stone terraces, chapels and cottages, Victorian seaside houses and post-war estates.
Repair options we may recommend
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.

Your boundary and garden wall repairs questions
What is the price of boundary and garden wall repairs in Llangefni?
Guide prices for boundary and garden wall repairs in Llangefni start from about £275 per wall, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out boundary and garden wall repairs in Llangefni?
Yes. We take enquiries from across Llangefni, including LL77, and from nearby places such as Bangor and Caernarfon. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Llangefni 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. Only an investigation can say why a particular building has moved.
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.
