Is Renfrewshire and Inverclyde prone to ground movement?
Johnstone (PA5) has around 16,000 residents and sits in Renfrewshire and Inverclyde. Nearby, we also cover 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. Housing stock in Renfrewshire and Inverclyde: Sandstone tenements, villas in East Renfrewshire, and post-war estates.
Repair options we may recommend
Underpinning to sound ground
Where the engineer specifies it, foundations are taken down by mass concrete, beam-and-base or mini-piles to ground that will not move further. On mining sites the design often follows grouting of old workings so the new foundation sits above a stable mass.
Best for: Ongoing movement or damage beyond what crack repairs can hold
Ground stabilisation by resin injection
For localised settlement in the upper soil layers, expanding resin can be injected beneath the footings to firm the ground and sometimes reduce a small tilt. It is not suitable for large voids deep below, which need grouting or other specialist treatment first.
Best for: Shallow settlement once deeper voids are ruled out or treated
What to expect when we carry out mining subsidence repairs
Report and photograph
Photograph every crack with a scale and note the date it appeared. Report suspected coal-mining damage to the Mining Remediation Authority, or the operator of a working mine, and notify your home insurer. Time limits can apply, so report promptly.
Written price to the scope
We price the repair from the engineer’s or claim schedule and confirm a fixed price in writing once the work is specified. Where a claim body or insurer is handling the repair, their own process for appointing contractors applies.
Repairs and records
Work proceeds once any ground treatment is complete and the engineer is satisfied. We stitch, stabilise or underpin as specified, make good inside and out, deal with building control where needed, and hand over records for your file.

Rules for mining subsidence repairs in Scotland
In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.
Your mining subsidence repairs questions
How much should I budget for mining subsidence repairs in Johnstone?
Guide prices for mining subsidence 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.
Can you survey a property in Johnstone?
Yes, Johnstone is covered, along with postcode districts PA5. We also cover nearby Paisley and Barrhead.
Why do houses in Renfrewshire and Inverclyde crack?
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.
Can mining subsidence start again years later?
It can, particularly over shallow workings or old shafts, where collapse can happen long after mining ended. Movement from deep longwall mining generally settled within a few years of extraction. An engineer can judge whether current damage is old, settled cracking or new movement.
Is my house affected by mining because it is on a coalfield?
Not necessarily. Many homes on coalfields have no mining-related damage at all, and cracks there can still come from clay, trees or drains. A coal mining report shows recorded workings nearby, and an engineer’s inspection is needed to link damage to mining.
