Wall tie replacement in Bangor
The first clue to failing wall ties in Bangor is usually a crack pattern: fine horizontal lines every few courses on one elevation. We confirm what is happening inside the cavity with a metal detector and borescope before recommending any new ties.

What should you know about the ground under Bangor?
We cover Bangor and its postcode districts LL57, LL59, part of Gwynedd, with a population of roughly 18,000. Nearby, we also cover Llangefni (8 miles), Caernarfon (9 miles) and Llandudno (14 miles).
Shrinkable clay is less common in Gwynedd than in south-east England. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Housing stock in Gwynedd: Slate and stone terraces, chapels and cottages, Victorian seaside houses and post-war estates.

Repair options we may recommend
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
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
What to expect when we carry out wall tie replacement
Tie survey
A metal detector locates the existing ties and shows their pattern. Small holes are then drilled at sample points and a borescope passed into the cavity to see the tie condition, type and embedment. The holes are made good afterwards.
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.
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.
Your wall tie replacement questions
How much will wall tie replacement cost in Bangor?
Guide prices for wall tie replacement in Bangor 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 Bangor?
Yes. We take enquiries from across Bangor, including LL57, LL59, and from nearby places such as Llangefni and Caernarfon. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Gwynedd prone to subsidence?
Gwynedd and Anglesey are mostly hard rock with glacial deposits, so clay shrinkage is uncommon. Historic slate quarrying and metal mining have left tips and workings in places. Only an investigation can say why a particular building has moved.
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.
Will a mortgage lender accept wall tie replacement?
Lenders generally accept properly carried out tie replacement, but they may want to see the survey, the quote or a record of the completed work. If a valuation has flagged wall ties, a written report and itemised quote are usually what the lender or buyer needs next.
