Wall tie replacement in Lanarkshire

Looking for wall tie replacement in Lanarkshire? Send us photos for a free initial view. Clay shrinkage is less of a concern in Lanarkshire, so other causes such as drains, poor footings or older walls are checked first, so we look at the ground, drains and nearby trees before recommending anything.

What is the ground like in Lanarkshire?

Lanarkshire lies on the Central Coalfield, mined intensively in the past around Hamilton, Motherwell, Airdrie and Coatbridge, so recorded workings are common beneath towns.

Historic coal workings are recorded beneath parts of Lanarkshire, and a coal mining search is worth checking where movement is unexplained. What you mostly find across Lanarkshire: miners' rows, sandstone tenements, inter-war council houses and new-town estates in East Kilbride and Cumbernauld.

What happens during wall tie replacement, step by step?

  1. 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.

  2. Access

    Ties are fitted across the whole of each affected elevation, so scaffold or a tower is usually needed above ground floor. We plan access around conservatories, extensions, neighbours’ land and any parking that must be suspended.

  3. 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.

What to look for before calling about wall tie replacement

  • Horizontal cracks along mortar joints, repeating every few brick courses
  • The roof edge or verge lifting slightly above the brickwork
  • Cracked render with a regular horizontal pattern
  • Mortar joints that look wider or opened up on one elevation

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

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

Do you need approval for wall tie replacement in Scotland?

In Scotland, small repairs often do not need a building warrant, but structural alterations and strengthening generally do. Check with the council’s building standards service if unsure; there is no Party Wall Act in Scotland.

Questions about wall tie replacement in Lanarkshire

Why do houses in Lanarkshire crack?

Lanarkshire lies on the Central Coalfield, mined intensively in the past around Hamilton, Motherwell, Airdrie and Coatbridge, so recorded workings are common beneath towns. Historic coal workings are recorded beneath parts of Lanarkshire, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.

How much will wall tie replacement cost in Lanarkshire?

On Scotland rates, wall tie replacement starts from about £1,700 per house, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

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.

Do all walls of the house need new ties?

Not necessarily, because ties often fail on one exposed elevation long before the others. The survey checks each wall, and the quote covers only the elevations where ties have failed or are close to it. Sheltered walls may simply be noted for future checks.
