Is Renfrewshire and Inverclyde prone to ground movement?
Johnstone (PA5) has around 16,000 residents and sits in Renfrewshire and Inverclyde. Nearby places we cover include Paisley (3 miles), Barrhead (5 miles) and Renfrew (6 miles).
Most of Renfrewshire and Inverclyde is on firmer ground than the clay belts of the south-east. Parts of Renfrewshire and Inverclyde lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Renfrewshire and Inverclyde: Sandstone tenements, villas in East Renfrewshire, and post-war estates.
What happens during structural crack repairs, step by step?
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.
Repair and make good
Cracks are stitched, repointed or rebuilt as specified, with mortar matched to the existing wall. Internal crack lines are filled and redecorated where included, and you get a written note of what was done.
What to look for before calling about structural crack repairs
- A crack noticeably wider at the top than the bottom, or the reverse
- Diagonal cracks running from the corners of windows and doors
- Stepped cracks zigzagging through the mortar joints of outside brickwork

How we usually approach 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
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
Rules for structural crack repairs in Scotland
In Scotland, small repairs often do not need a building warrant, but structural alterations and strengthening generally do. Check with the council’s building standards service if unsure; there is no Party Wall Act in Scotland.
Questions about structural crack repairs in Johnstone
What is the price of structural crack repairs in Johnstone?
Guide prices for structural crack repairs in Johnstone 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 carry out structural crack repairs in Johnstone?
Yes. We take enquiries from across Johnstone, including PA5, and from nearby places such as Paisley and Barrhead. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Johnstone cause cracking?
Renfrewshire has glacial till and Clyde alluvium with coal workings recorded in parts, while Inverclyde's towns climb steep slopes above the Clyde with many retaining walls. Only an investigation can say why a particular building has moved.
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.
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.
