Structural crack repairs in Leigh
Whether your Leigh home is a Victorian terrace or a post-war semi, a crack follows the weakest line through the masonry. Reading that line correctly is the difference between a repair that lasts and one that splits open again next summer.

How do local ground conditions affect structural crack repairs in Leigh?
Leigh, Greater Manchester: about 44,000 residents across postcode districts WN7. Nearby places we cover include Tyldesley (2 miles), Westhoughton (4 miles) and Hindley (4 miles).
Greater Manchester has a mix of ground, with clay in some places and firmer rock in others.

What you mostly find across Greater Manchester: red-brick terraces, mill-town stone terraces, inter-war semis and post-war estates.
Methods for structural crack repairs
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
From first photo to finished repair
Deal with the cause
Leaking drains, failed ties, a sagging lintel or ground movement are put right first, sometimes through an insurance claim. Repairing a crack before its cause is fixed usually means paying for the same job twice.
Written quote
You receive a no-obligation written quote listing each crack, the repair method chosen for it and the making good inside and out. Once the scope is settled, that becomes a fixed price in writing.
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.
Symptoms that point to structural crack repairs
- Stepped cracks zigzagging through the mortar joints of outside brickwork
- Daylight or a draught coming through a crack in an outside wall
- A crack noticeably wider at the top than the bottom, or the reverse

Frequently asked questions
How much should I budget for structural crack repairs in Leigh?
Guide prices for structural crack repairs in Leigh 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.

Why do houses in Greater Manchester crack?
Greater Manchester is mostly glacial till over sandstone and mudstone, with the Lancashire coalfield beneath much of Wigan, Bolton, Salford and parts of the east. Historic mine workings, made ground and old mill sites are common. Only an investigation can say why a particular building has moved.
What causes vertical cracks in walls?
Vertical cracks are most often caused by thermal or moisture movement in long walls, or by the joint between old and newer work. An even-width vertical crack is usually cosmetic. One clearly wider at the top or bottom can indicate foundation movement at one end.
Can I just fill a crack and paint over it?
You can fill a fine crack that is not moving, and for many hairline cracks that is the right repair. Filling a crack that is still opening hides the evidence, and it will usually come back. If a filled crack returns within a year or two, have it assessed.
