Methods for structural crack repairs
Filling and repointing
For hairline and narrow cracks that have stopped moving, the crack line is raked out and repointed in mortar matched to the original for strength, colour and texture. Inside, plaster cracks are cut out, filled with a flexible filler and redecorated.
Best for: Cracks up to about 5 mm that are no longer moving
Rebuilding a cracked section
Where bricks have split or the wall has moved out of line, the damaged area is taken down and rebuilt, bonded into sound masonry on either side. Reclaimed or matched bricks keep the repair discreet, with temporary support used where needed.
Best for: Badly displaced or broken brickwork

Survey and record
On site we measure the width along the crack, note its pattern and check nearby drains, trees and openings. If the cause is unclear, gauges can be fixed across it and read over several months.
Written quote
You receive a no-obligation written quote listing each crack, the repair method chosen for it and the making good inside and out. Once the scope is settled, that becomes a fixed price in writing.

Frequently asked questions
What is the price of structural crack repairs in Coleraine?
Guide prices for structural crack repairs in Coleraine start from about £70 per metre of crack, 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.
Do you carry out structural crack repairs in Coleraine?
Yes. We take enquiries from across Coleraine, including BT52, and from nearby places such as Ballymoney and Limavady. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Coleraine cause cracking?
County Londonderry has basalt, older hard rock and glacial deposits, with soft river ground along the Foyle and Bann. Only an investigation can say why a particular building has moved.
Do I need a structural engineer for a cracked wall?
Not always, since many cracks can be judged from photos and a visit. An engineer is worthwhile when cracks are wide, tapered, growing or part of a claim. Where the repair needs an engineer’s design or sign-off, an independent chartered structural engineer is appointed, and we can arrange this.
Should I tell my insurer about cracks in my house?
Yes, if you think the cracks could come from subsidence or heave, tell your insurer before any permanent repair, because repairing first can make a claim harder to prove. Cracks from normal shrinkage or ageing are not usually covered, and the insurer decides which applies.
