Methods for boundary and garden wall repairs

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

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

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.
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.

Frequently asked questions

What is the price of boundary and garden wall repairs in Penarth?

Guide prices for boundary and garden wall repairs in Penarth 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 Penarth?

Yes, Penarth is covered, along with postcode districts CF64. We also cover nearby Cardiff and Barry.

Does the ground around Penarth cause cracking?

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.

Can tree roots damage a garden wall?

Yes, they often do. Roots can lift footings, push walls sideways and, on clay soils, dry the ground so it shrinks under the wall. A wall can sometimes be rebuilt to bridge roots. Take advice before removing a large tree, as it may be protected and removal on clay can cause heave.
