Which repair method suits a home in Abergavenny?
Isolating the old ties
Where the old ties are swelling and cracking the brickwork, fitting new ties alone may not stop further damage. Each old tie can be isolated, usually by cutting it through within the cavity or sleeving its outer end, so it can no longer lift the outer leaf as it continues to corrode.
Best for: Thick mild steel ties still causing horizontal cracking
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
What happens when we carry out wall tie replacement in Abergavenny?
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.
Signs you may need wall tie replacement
- A house built before the 1980s on an exposed or coastal site
- Horizontal cracks along mortar joints, repeating every few brick courses
- 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.
Wall tie replacement in Abergavenny: questions and answers
How much will wall tie replacement cost in Abergavenny?
Guide prices for wall tie replacement in Abergavenny 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.
Do you cover Abergavenny?
Yes, Abergavenny is covered, along with postcode districts NP7. We also cover nearby Abertillery and Pontypool.
Is the ground in Gwent prone to subsidence?
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.
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.
Can wall ties be replaced on a rendered house?
Yes, new ties can be fitted through render, with each drill hole made good afterwards. The repairs can show on painted render, so redecoration of the affected elevation is often worth including. Render can also hide the cracking pattern, so a survey matters more.
