Is Renfrewshire and Inverclyde prone to ground movement?
Postcode districts PA5 cover Johnstone, a Renfrewshire and Inverclyde town of about 16,000 people. Nearby places we cover include Paisley (3 miles), Barrhead (5 miles) and Renfrew (6 miles).
Shrinkable clay is less common in Renfrewshire and Inverclyde than in south-east England. Parts of Renfrewshire and Inverclyde lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Renfrewshire and Inverclyde: Sandstone tenements, villas in East Renfrewshire, and post-war estates.
What happens when we carry out wall tie replacement in Johnstone?
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.
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.
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.
Signs you may need wall tie replacement
- The roof edge or verge lifting slightly above the brickwork
- Horizontal cracks along mortar joints, repeating every few brick courses
- Cracked render with a regular horizontal pattern

Which repair method suits a home in Johnstone?
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

Wall tie replacement in Johnstone: questions and answers
How much should I budget for wall tie replacement in Johnstone?
Guide prices for wall tie replacement in Johnstone start from about £1,700 per house, including VAT, on Scotland 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 Johnstone?
Yes. We take enquiries from across Johnstone, including PA5, and from nearby places such as Paisley and Barrhead. Send photos for a free initial view and we will tell you what happens next.
Why do houses in Renfrewshire and Inverclyde crack?
Renfrewshire has glacial till and Clyde alluvium with coal workings recorded in parts, while Inverclyde's towns climb steep slopes above the Clyde with many retaining walls. Only an investigation can say why a particular building has moved.
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.
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.
