Which repair method suits a home in Dumfries?
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
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 when we carry out wall tie replacement in Dumfries?
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.
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
- Outer brickwork bowing or bulging, often worst near the top
- The roof edge or verge lifting slightly above the brickwork
- Horizontal cracks along mortar joints, repeating every few brick courses

Wall tie replacement in Dumfries: questions and answers
How much should I budget for wall tie replacement in Dumfries?
Guide prices for wall tie replacement in Dumfries 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 Dumfries?
Yes, Dumfries is covered, along with postcode districts DG1, DG2. We also cover nearby Annan.
Why do houses in Dumfries and Galloway crack?
Dumfries and Galloway is mainly older hard rock and red sandstone with glacial deposits, and soft estuarine ground along the Solway coast. Only an investigation can say why a particular building has moved.
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.
