Structural crack repairs in Norwich
Whether your Norwich 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.

Is Norfolk prone to ground movement?
Norwich (NR1, NR2, NR3, NR4, NR5) has around 140,000 residents and sits in Norfolk. We also take enquiries from nearby East Dereham (16 miles), Great Yarmouth (18 miles) and Lowestoft (22 miles).
Clay soils are found in parts of Norfolk. Ground movement here is more often linked to soils, drains and trees than to mining. Across Norfolk, most homes are flint and brick cottages, Victorian terraces in Norwich and Great Yarmouth, and post-war bungalows.
What happens during structural crack repairs, step by step?
Send photos
Photograph the crack from a distance and close up, with a coin or tape measure for scale. From these we say whether it looks cosmetic, needs a visit or calls for an engineer.
Survey and record
On site we measure the width along the crack, note its pattern and check nearby drains, trees and openings. If the cause is unclear, gauges can be fixed across it and read over several months.
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.
What to look for before calling about structural crack repairs
- Doors or windows that have started sticking or no longer latch

How we usually approach structural crack repairs
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
Crack stitching with helical bars
Stainless steel helical bars are grouted into slots cut along the bed joints, bridging the crack so the masonry works as one piece again. It is the standard repair for wider stepped and vertical cracks once whatever caused them has stopped.
Best for: Stable cracks wider than about 5 mm, or ones that keep reopening
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.
Questions about structural crack repairs in Norwich
How much should I budget for structural crack repairs in Norwich?
Guide prices for structural crack repairs in Norwich start from about £85 per metre of crack, including VAT, on East of England 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 Norwich?
Yes, Norwich is covered, along with postcode districts NR1, NR2, NR3, NR4. We also cover nearby East Dereham and Great Yarmouth.
Why do houses in Norfolk crack?
Norfolk is chalk covered by glacial sands, gravels and boulder clay, with fen silts in the west and soft cliffs on the north-east coast. Boulder clay areas can shrink near trees, and historic chalk mines are recorded under parts of Norwich. 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.
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.
