What should you know about the ground under Llangefni?

With roughly 5,500 people, Llangefni spans postcode districts LL77 in Gwynedd. Nearby places we cover include Bangor (8 miles), Caernarfon (8 miles) and Holyhead (14 miles).

Most of Gwynedd is on firmer ground than the clay belts of the south-east. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Gwynedd, most homes are slate and stone terraces, chapels and cottages, Victorian seaside houses and post-war estates.

Methods for wall tie replacement

Removing old ties and rebedding

On badly cracked elevations the old ties are cut out from the outer face, the joints raked and rebedded, and the brickwork repointed. It is more work than isolation but removes the source of expansion entirely. An engineer or the survey report usually specifies where this is needed.

Best for: Elevations with severe cracking or lifting

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

From first photo to finished repair

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.

Frequently asked questions

How much should I budget for wall tie replacement in Llangefni?

Guide prices for wall tie replacement in Llangefni 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.

Can you survey a property in Llangefni?

We do. Llangefni and the surrounding area are covered, including nearby Bangor and Caernarfon. A free initial assessment from your photos is the first step.

Why do houses in Gwynedd crack?

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.

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.
