Subsidence repairs in Bodmin
Seasonal movement is behind a lot of subsidence, and once its cause is clear it is usually manageable for a home in Bodmin as much as anywhere. The repair that follows is mostly crack stitching, repointing and replastering, with foundation work kept for houses that need it.

What should you know about the ground under Bodmin?
Bodmin (PL31) has around 17,000 residents and sits in Cornwall. If you are just outside Bodmin, we also cover St Austell (9 miles), Newquay (16 miles) and Truro (20 miles).
Clay shrinkage is less of a concern in Cornwall, so other causes such as drains, poor footings or older walls are checked first. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Housing stock in Cornwall: Granite and slate-stone cottages, cob buildings, Victorian terraces and post-war estates.
How we usually approach subsidence repairs
Crack stitching and making good
Once movement has stopped, cracked brickwork is cut along the bed joints, stainless helical bars are bonded in to tie the wall together, and the joints are repointed to match. Inside, plaster is renewed along the crack line before redecoration.
Best for: Category 1 to 3 cracking in walls that are otherwise sound
Foundation strengthening
Where the ground cannot be made stable, the load is carried down to firmer soil by underpinning, a beam-and-base scheme, mini-piles or resin injection, depending on the soil and access. It is designed by an engineer and is the exception, not the rule.
Best for: Ongoing movement where removing the cause has not worked
What happens during subsidence repairs, step by step?
Send photos or call
Send photos of the cracks with a coin or tape for scale, and say when you first noticed them. We give a free initial assessment and suggest whether an engineer, a drain survey or your insurer comes first.
Find the cause
An independent chartered structural engineer inspects the house and, where needed, arranges a drain survey, trial pits or soil tests. We can arrange the engineer. The aim is to know what is moving, and why, before money goes on repairs.
Deal with the cause
Drains are repaired, vegetation is managed on the engineer’s advice, or a foundation scheme is designed if nothing else will work. Where monitoring is recommended, readings run for several months to show the movement has stopped.
What to look for before calling about subsidence repairs
- Cracks that open in summer and partly close again in winter
- Diagonal cracks wider at the top, running from window or door corners
- Doors and windows that start to stick or no longer close

Rules for subsidence repairs in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Questions about subsidence repairs in Bodmin
How much should I budget for subsidence repairs in Bodmin?
Guide prices for subsidence repairs in Bodmin start from about £2,600 per property, 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.
Can you survey a property in Bodmin?
Yes. We take enquiries from across Bodmin, including PL31, and from nearby places such as St Austell and Newquay. Send photos for a free initial view and we will tell you what happens next.
Why do houses in Cornwall crack?
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.
Can I sell a house that has had subsidence?
Yes, though buyers and lenders will want paperwork. Keep the engineer’s report, monitoring results, the repair specification and any building control sign-off. A repaired house shown to be stable is far easier to sell than one with an open problem.
Will past subsidence affect my home insurance?
It can, because insurers ask about previous subsidence at renewal or when you switch. Staying with the insurer who handled a claim is often simplest. Answer any new insurer’s questions honestly and keep the repair records, which show the problem was dealt with.
