What is the ground like in Gwent?
With roughly 10,000 people, Monmouth spans postcode districts NP25 in Gwent. We also take enquiries from nearby Chepstow (12 miles), Abergavenny (13 miles) and Pontypool (16 miles).
Gwent has a mix of ground, with clay in some places and firmer rock in others. Historic coal workings are recorded beneath parts of Gwent, and a coal mining search is worth checking where movement is unexplained. Typical buildings in Gwent: Valley terraces on steep hillsides, Victorian houses in Newport and Abergavenny, and post-war estates.

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.
Symptoms that point to boundary and garden wall repairs

Methods for boundary and garden wall repairs
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
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 Monmouth?
Guide prices for boundary and garden wall repairs in Monmouth 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 Monmouth?
We do. Monmouth and the surrounding area are covered, including nearby Chepstow and Abergavenny. A free initial assessment from your photos is the first step.
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.
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.
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.
