What is the ground like in Lancashire?
Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns.
Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause.
What usually causes cracking in Lancashire?
In Lancashire, cracking usually comes back to one of these. We rule each in or out before recommending a repair.
- Clay in parts of the area that dries out near trees in long dry spells
- Old coal workings, where they lie close to the surface in the former coalfield
- Heavy stone chimneys and gables pulling away from the house
- Solid stone walls bulging where the rubble core has loosened
- Leaking or broken drains washing fine soil out from under footings
What kind of buildings are common here?
Stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.

Do repairs in Lancashire need approval?
In England, building control approves and inspects structural work such as underpinning; small like-for-like repairs usually do not need it. Party wall notices apply where work affects a shared wall.
Questions about structural repairs in Lancashire
Do you cover the whole of Lancashire?
Yes. We take enquiries from across Lancashire, including Preston, Burnley, Blackburn and Blackpool. A free initial assessment from your photos is the first step.
Is Lancashire affected by subsidence?
Clay soils are found in parts of Lancashire. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Whether a particular building has moved, and why, needs an investigation on site.
How much do structural repairs cost in Lancashire?
It depends on the repair. On North West rates, mass-concrete underpinning from about £960 per metre of wall and lateral restraint for a bowing gable from about £960 per wall, including VAT. Your written price follows photos or a survey.
What should I send for a free assessment in Lancashire?
Photos of each crack inside and out with a coin or tape for scale, a wider shot showing where it is on the building, your postcode in Lancashire, and when you first noticed it. If an insurer is involved, include the claim reference.
