Structural crack repairs in Truro
A cracked wall in Truro does not automatically mean subsidence. Thermal movement, rusting wall ties, tired lintels and old drains each leave their own pattern, and we look at the whole picture before recommending any repair to the brickwork.

What should you know about the ground under Truro?
Postcode districts TR1 cover Truro, a Cornwall town of about 23,000 people. We also take enquiries from nearby Falmouth (8 miles), Redruth (8 miles) and Newquay (10 miles).
Most of Cornwall is on firmer ground than the clay belts of the south-east. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Typical buildings in Cornwall: Granite and slate-stone cottages, cob buildings, Victorian terraces and post-war estates.
From first photo to finished repair
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.
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.
Symptoms that point to structural crack repairs
- Cracks that reappear in the same place after filling and painting
- Stepped cracks zigzagging through the mortar joints of outside brickwork
- A crack noticeably wider at the top than the bottom, or the reverse

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
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.
Frequently asked questions
How much will structural crack repairs cost in Truro?
Guide prices for structural crack repairs in Truro start from about £80 per metre of crack, including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Truro?
Yes, Truro is covered, along with postcode districts TR1. We also cover nearby Falmouth and Redruth.
Is the ground in Cornwall prone to subsidence?
Cornwall is mostly granite and slate with little shrinkable clay, so clay subsidence is less common than in the south-east. Historic tin and copper mining has left shafts and workings in places such as Camborne and Redruth, and mining searches are routine there. 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.
When is a crack in a wall structural?
A crack is more likely to be structural when it is wider than about 5 mm, tapers, passes through the whole wall or keeps growing. BRE Digest 251 treats damage up to about 5 mm as aesthetic and over 25 mm as a stability concern. Width is a guide, not a diagnosis.
