Boundary and garden wall repairs in Cardiff
Front and garden walls in Cardiff take the weather on both faces and along the top, so they often fail sooner than the house they surround. Crumbling joints, loose copings and a slow lean are the usual signs that the wall needs attention.

Which repair method suits a home in Cardiff?
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
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
What happens when we carry out boundary and garden wall repairs in Cardiff?
Photos and ownership
Send photos of the whole wall and close-ups of cracks, the lean and the coping, plus any nearby trees. Tell us whether the wall is yours, shared or your neighbour’s, as that affects who can instruct the work.
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.
Rules for boundary and garden wall repairs in Wales
In Wales, small like-for-like repairs do not usually need approval, but work that alters or strengthens the structure needs building control under the Welsh Building Regulations, and the Party Wall etc. Act 1996 can apply to shared walls.
Boundary and garden wall repairs in Cardiff: questions and answers
How much will boundary and garden wall repairs cost in Cardiff?
Guide prices for boundary and garden wall repairs in Cardiff 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 cover Cardiff?
Yes, Cardiff is covered, along with postcode districts CF10, CF11, CF24. We also cover nearby Penarth and Caerphilly.
Is the ground in South Glamorgan prone to subsidence?
Cardiff is built on Mercia Mudstone, river gravels and alluvium, and the Vale of Glamorgan on Lias limestone and clay. Soft alluvium near the rivers and docks can settle. Only an investigation can say why a particular building has moved.
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.
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.
