Structural crack repairs in Alexandria
A cracked wall in Alexandria does not automatically mean subsidence. Thermal movement, rusting wall ties, tired lintels and old drains each leave their own pattern, and we look at the whole picture before recommending any repair to the brickwork.

What should you know about the ground under Alexandria?
Alexandria, Dunbartonshire: about 25,000 residents across postcode districts G83. Neighbouring towns we cover: Port Glasgow (5 miles), Helensburgh (6 miles) and Greenock (7 miles).
Shrinkable clay is less common in Dunbartonshire than in south-east England. Parts of Dunbartonshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Dunbartonshire, most homes are tenements, Victorian villas in Bearsden and Milngavie, and post-war estates.
Methods for structural crack repairs
Crack stitching with helical bars
Stainless steel helical bars are grouted into slots cut along the bed joints, bridging the crack so the masonry works as one piece again. It is the standard repair for wider stepped and vertical cracks once whatever caused them has stopped.
Best for: Stable cracks wider than about 5 mm, or ones that keep reopening
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
From first photo to finished repair
Send photos
Photograph the crack from a distance and close up, with a coin or tape measure for scale. From these we say whether it looks cosmetic, needs a visit or calls for an engineer.
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.
Deal with the cause
Leaking drains, failed ties, a sagging lintel or ground movement are put right first, sometimes through an insurance claim. Repairing a crack before its cause is fixed usually means paying for the same job twice.

Frequently asked questions
How much will structural crack repairs cost in Alexandria?
Guide prices for structural crack repairs in Alexandria start from about £75 per metre of crack, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Alexandria?
Yes, Alexandria is covered, along with postcode districts G83. We also cover nearby Port Glasgow and Helensburgh.
Is the ground in Dunbartonshire prone to subsidence?
Dunbartonshire has glacial till over sandstone and volcanic rock, with coal and ironstone workings recorded around Kirkintilloch and Bishopbriggs and soft river ground along the Clyde and Leven. Only an investigation can say why a particular building has moved.
What causes vertical cracks in walls?
Vertical cracks are most often caused by thermal or moisture movement in long walls, or by the joint between old and newer work. An even-width vertical crack is usually cosmetic. One clearly wider at the top or bottom can indicate foundation movement at one end.
What do stepped cracks in brickwork mean?
Stepped cracks usually mean part of the wall has moved and the weakest path, the mortar joints, has given way. They are common with subsidence and around openings. A thin stepped crack unchanged for years is often cosmetic, while a wide or tapered one should be looked at.
