Wall tie replacement in Perth

Which repair method suits a home in Perth?
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
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 when we carry out wall tie replacement in Perth?
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.
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.
Signs you may need wall tie replacement
- Outer brickwork bowing or bulging, often worst near the top
- Horizontal cracks along mortar joints, repeating every few brick courses
- A house built before the 1980s on an exposed or coastal site

Do you cover Perth?
Yes, Perth is covered, along with postcode districts PH1, PH2. We also cover nearby Blairgowrie and Crieff.
Is the ground in Perth and Kinross prone to subsidence?
Perth and Kinross is largely Old Red Sandstone and Highland rock with glacial deposits and river alluvium along the Tay, which can be soft and flood-prone. Only an investigation can say why a particular building has moved.
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.
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.
