Underpinning in Greenock
Underpinning a house in Greenock starts with proof that it is needed, not with a digger. An independent engineer looks at the monitoring and ground investigation, then chooses between mass concrete, beam-and-base or mini-piles for that particular wall and soil.

What is the ground like in Renfrewshire and Inverclyde?
We cover Greenock and its postcode districts PA14, PA15, PA16, PA19, part of Renfrewshire and Inverclyde, with a population of roughly 41,000. Nearby, we also cover Gourock (2 miles), Port Glasgow (3 miles) and Alexandria (7 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.

Repair options we may recommend
Mini-piled underpinning
Small-diameter piles are driven or bored down to firm ground and linked by a reinforced beam or needles that pick up the wall. Compact rigs fit through narrow access, and the method reaches depths that would be impractical to excavate by hand.
Best for: Deep soft ground, tree roots, or restricted access
Mass concrete underpinning
The traditional method. Short sections under the wall are dug out in a set sequence, usually about a metre at a time, and filled with concrete before the next section is opened. It suits moderate depths and good access, and it needs little specialist plant.
Best for: Shallow failures on firm ground found at moderate depth
What to expect when we carry out underpinning
Design and approvals
The engineer produces drawings and calculations. We make the building control or building warrant application, and party wall notices are served where the law requires them, before any digging starts.
Fixed written price
With the design in hand we confirm a fixed price in writing, setting out the method, the length of wall, access arrangements and the making good. For insurance work we can price to the loss adjuster’s or engineer’s schedule.
Crack repairs and handover
Once the new foundation has cured, cracks are stitched and repointed, inside walls are made good, and paths or patios disturbed by the dig are reinstated. You receive the building control completion paperwork for your records.
Rules for underpinning 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 underpinning questions
How much will underpinning cost in Greenock?
Guide prices for underpinning in Greenock start from about £950 per metre of wall, 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 Greenock?
Yes. We take enquiries from across Greenock, including PA14, PA15, PA16, PA19, and from nearby places such as Gourock and Port Glasgow. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Renfrewshire and Inverclyde prone to subsidence?
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 I stay in my house during underpinning?
Most people stay at home during external underpinning, because the digging happens outside along the wall. Expect noise, restricted access to that side of the house and some dust. If the work has to be done from inside, through the floor, moving out for part of the job is sometimes advised.
Can you underpin only part of a house?
Yes, partial underpinning of one corner or one wall is common, though the engineer must think about the junction with the unstrengthened part. A sudden change in foundation depth can cause new cracking, so the scheme may step down gradually or include a movement joint.
