Is Merseyside prone to ground movement?
St Helens is in Merseyside and takes in postcode districts WA9, WA10, WA11. About 180,000 people live there. Nearby, we also cover Prescot (3 miles), Ashton-in-Makerfield (4 miles) and Huyton (5 miles).
Merseyside has a mix of ground, with clay in some places and firmer rock in others. Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Merseyside, most homes are Victorian terraces and villas, inter-war council estates and post-war semis.

Which repair method suits a home in St Helens?
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
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
Rules for structural crack repairs in England
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.
Structural crack repairs in St Helens: questions and answers
What is the price of structural crack repairs in St Helens?
Guide prices for structural crack repairs in St Helens start from about £75 per metre of crack, including VAT, on North West 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 St Helens?
Yes. We take enquiries from across St Helens, including WA9, WA10, WA11, and from nearby places such as Prescot and Ashton-in-Makerfield. Send photos for a free initial view and we will tell you what happens next.
Does the ground around St Helens cause cracking?
Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places. Only an investigation can say why a particular building has moved.
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.
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.
