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
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

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.
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.
Frequently asked questions
How much should I budget for boundary and garden wall repairs in Blackwood?
Guide prices for boundary and garden wall repairs in Blackwood 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.
Can you survey a property in Blackwood?
Yes. We take enquiries from across Blackwood, including NP12, and from nearby places such as Abercarn and Nelson. Send photos for a free initial view and we will tell you what happens next.
Why do houses in Gwent crack?
The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. 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.
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.
