How we usually approach wall tie replacement
Partial rebuild of the outer leaf
If a section of the outer leaf has bulged too far to be tied back, it is carefully taken down and rebuilt with new ties built in as the work goes up. This is uncommon, and is usually limited to a gable top, a parapet or a panel under a window.
Best for: Outer leaf too distorted to tie back safely
Remedial tie installation
New stainless ties are drilled through the outer leaf into the inner leaf, then fixed by mechanical expansion or resin, depending on the masonry. They are placed to a set grid across each elevation, with extra ties around openings and at the edges. Holes are made good in matching mortar.
Best for: Walls where the original ties have failed or are missing
What happens during wall tie replacement, step by step?
Report and quote
You receive a written summary of what the survey found on each elevation, which walls need new ties, whether old ties should be isolated or removed, and a no-obligation written quote with scaffold shown separately.
Install the new ties
New stainless ties are drilled and fixed to the specified grid, with closer spacing around windows, doors and the roofline. Sample ties can be pull-tested to confirm they are holding in your particular brick and block.
Deal with the old ties and make good
Old ties are isolated or removed where the report calls for it, cracked joints are raked out and repointed, and drilled holes are filled in matching mortar. A written note of tie positions and findings goes in your property file.
What to look for before calling about wall tie replacement
- A house built before the 1980s on an exposed or coastal site
- The roof edge or verge lifting slightly above the brickwork
- Mortar joints that look wider or opened up on one elevation
Rules for wall tie replacement 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.
Questions about wall tie replacement in Llantwit Major
How much should I budget for wall tie replacement in Llantwit Major?
Guide prices for wall tie replacement in Llantwit Major start from about £1,650 per house, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in South Glamorgan crack?
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.
Do the old wall ties have to be removed?
Not always, because thin wire ties that cannot swell are usually left in place once new ties are fitted. Thicker ties that are still expanding and cracking the wall are isolated or removed so they stop causing damage. The survey decides which applies.
Is wall tie failure covered by insurance?
Usually not, because insurers treat it as gradual deterioration. Damage caused by a sudden event, such as part of a wall collapsing in a storm, may be treated differently under some policies. Check your policy wording, and tell your insurer if you are unsure.
