What should you know about the ground under Dunbartonshire?

Dunbartonshire has glacial till over sandstone and volcanic rock, with coal and ironstone workings recorded around Kirkintilloch and Bishopbriggs and soft river ground along the Clyde and Leven.

Parts of Dunbartonshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Dunbartonshire, most homes are tenements, Victorian villas in Bearsden and Milngavie, and post-war estates.

What to look for before calling about wall tie replacement

  • The roof edge or verge lifting slightly above the brickwork
  • Outer brickwork bowing or bulging, often worst near the top
  • Mortar joints that look wider or opened up on one elevation
  • Cracked render with a regular horizontal pattern

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

What happens during wall tie replacement, step by step?

  1. 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.

  2. 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.

  3. 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.

Questions about wall tie replacement in Dunbartonshire

Is the ground in Dunbartonshire prone to subsidence?

Dunbartonshire has glacial till over sandstone and volcanic rock, with coal and ironstone workings recorded around Kirkintilloch and Bishopbriggs and soft river ground along the Clyde and Leven. Parts of Dunbartonshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will wall tie replacement cost in Dunbartonshire?

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.

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.

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.

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.
