Extension pulling away repairs in Strabane
The ground under Strabane and County Tyrone varies street by street, and extensions built on shallower footings feel those differences first. A trial pit and a drain survey usually tell an engineer how the extension’s foundation is coping.

Is County Tyrone prone to ground movement?
With roughly 14,000 people, Strabane spans postcode districts BT82 in County Tyrone. Nearby, we also cover Derry (14 miles) and Omagh (17 miles).
Most of County Tyrone is on firmer ground than the clay belts of the south-east. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in County Tyrone: Market-town terraces, rural houses and post-war estates.
Which repair method suits a home in Strabane?
Movement joint and making good
Where some seasonal movement is expected to continue, the junction is formed into a proper flexible movement joint with a compressible filler and sealant, so the two parts can move without cracking. Flashings and internal finishes are detailed to suit.
Best for: Minor ongoing movement that does not threaten the structure
Underpinning the extension
If the extension is still dropping because its footings are too shallow or on poor ground, they are taken deeper by mass concrete, beam-and-base or mini-piles. The engineer designs the scheme, and the junction is repaired once the new foundation is in.
Best for: Active movement from shallow footings, roots or soft ground
What happens when we carry out extension pulling away repairs in Strabane?
Show us the junction
Send photos of the crack outside, the internal corner and any flashing above, with a measure for scale. We give a free initial assessment and an initial view on whether the gap is likely old or still opening.
Find what is moving
An independent chartered structural engineer can inspect, and we can arrange one. A drain survey under the extension, a trial pit at its footing and tell-tale monitoring across the joint are common checks before choosing the repair.
Finish and hand over
Internal corners are replastered, skirtings and coving refixed, and doors or windows in the extension eased where the movement affected them. Records of the repair and any approvals are passed to you.

Extension pulling away repairs in Strabane: questions and answers
How much should I budget for extension pulling away repairs in Strabane?
Guide prices for extension pulling away repairs in Strabane start from about £530 per junction, 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 Strabane?
We do. Strabane and the surrounding area are covered, including nearby Derry and Omagh. A free initial assessment from your photos is the first step.
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.
Is it normal for an extension to crack at the join?
A fine crack at the junction is fairly common, especially in the first few years as a new extension settles. It becomes a concern when the gap is widening, tapering, letting in water or matched by sticking doors and sloping floors. Those signs point to continuing movement.
Can a drain under my extension cause it to move?
Yes, a cracked or displaced drain beneath or beside an extension can soften clay or wash away fine soil. A CCTV drain survey usually finds it. Repairing the drain is often the first and most important step before any repair to the walls.
