Clay shrinkage is less of a concern in County Tyrone, so other causes such as drains, poor footings or older walls are checked first. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across County Tyrone, most homes are market-town terraces, rural houses and post-war estates.

Repair options we may recommend
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
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
What to expect when we carry out wall tie replacement
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.
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.
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.

Your wall tie replacement questions
How much should I budget for wall tie replacement in Cookstown?
Guide prices for wall tie replacement in Cookstown start from about £1,600 per house, including VAT, on Northern Ireland 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 Cookstown?
Yes, Cookstown is covered, along with postcode districts BT80. We also cover nearby Magherafelt and Dungannon.
Why do houses in County Tyrone crack?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon. Only an investigation can say why a particular building has moved.
Which houses are most at risk of wall tie failure?
Cavity-walled houses built before the 1980s are most at risk, especially those with mild steel ties, black ash mortar or an exposed position. Coastal and hilltop houses, and elevations facing the prevailing weather, tend to fail first.
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.
