How we usually approach wall tie replacement

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 during wall tie replacement, step by step?

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.
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.

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 Flint

What is the price of wall tie replacement in Flint?

Guide prices for wall tie replacement in Flint 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 carry out wall tie replacement in Flint?

Yes, Flint is covered, along with postcode districts CH6. We also cover nearby Connah's Quay and Mold.

Does the ground around Flint cause cracking?

The North Wales coalfield runs beneath parts of Wrexham and Flintshire, where historic workings are recorded, while the coast and vale have glacial clays and the hills are older hard rock. Only an investigation can say why a particular building has moved.

Which houses are most at risk of wall tie failure?

Cavity-walled houses built before the 1980s are most at risk, especially those with mild steel ties, black ash mortar or an exposed position. Coastal and hilltop houses, and elevations facing the prevailing weather, tend to fail first.

How do I know if my wall ties have failed?

The clearest sign is horizontal cracking in the mortar joints repeating every few courses, often with a bulge or a lifted roofline. Wire ties can fail with no cracking at all, so a tie survey with a metal detector and borescope is the only reliable check.
