Underpinning in Torquay
Most underpinning in Torquay, as elsewhere, is partial, strengthening one corner or a single wall rather than the whole house. The engineer plans how the new foundation meets the old so that the junction does not become the next place to crack.

What should you know about the ground under Torquay?
We cover Torquay and its postcode districts TQ1, TQ2, TQ3, TQ4, part of Devon, with a population of roughly 65,000. We also take enquiries from nearby Paignton (3 miles), Brixham (5 miles) and Newton Abbot (6 miles).
Shrinkable clay is less common in Devon than in south-east England. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Devon, most homes are cob and stone cottages, Victorian terraces in Exeter, Plymouth and Torbay, and post-war estates.

How we usually approach underpinning
Beam-and-base underpinning
A reinforced concrete beam is cast beneath or alongside the existing footing and carries the wall onto mass concrete bases at intervals. It spreads load well across variable ground and can mean less digging than continuous underpinning along the whole wall.
Best for: Longer runs of wall or heavier loads over variable ground
Mini-piled underpinning
Small-diameter piles are driven or bored down to firm ground and linked by a reinforced beam or needles that pick up the wall. Compact rigs fit through narrow access, and the method reaches depths that would be impractical to excavate by hand.
Best for: Deep soft ground, tree roots, or restricted access
What happens during underpinning, step by step?
Design and approvals
The engineer produces drawings and calculations. We make the building control or building warrant application, and party wall notices are served where the law requires them, before any digging starts.
Excavation and concrete
Work runs in the sequence the engineer sets so the wall is never left unsupported over a long length. Building control inspects the excavations before concrete goes in, and each section is dry-packed tight to the footing above.
Crack repairs and handover
Once the new foundation has cured, cracks are stitched and repointed, inside walls are made good, and paths or patios disturbed by the dig are reinstated. You receive the building control completion paperwork for your records.
What to look for before calling about underpinning
- Footings found to be very shallow during a trial pit
- Cracks that keep widening after the drains have been repaired
- Movement continuing through more than one winter of monitoring
Rules for underpinning 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 underpinning in Torquay
How much should I budget for underpinning in Torquay?
Guide prices for underpinning in Torquay start from about £1,050 per metre of wall, 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 Torquay?
Yes, Torquay is covered, along with postcode districts TQ1, TQ2, TQ3, TQ4. We also cover nearby Paignton and Brixham.
Why do houses in Devon crack?
Devon's ground is mostly older mudstones, sandstones and granite, so shrinkable-clay subsidence is less widespread than further east. Older solid-walled and cob buildings, steep sites and retaining walls are the more common structural concerns. Only an investigation can say why a particular building has moved.
Can I stay in my house during underpinning?
Most people stay at home during external underpinning, because the digging happens outside along the wall. Expect noise, restricted access to that side of the house and some dust. If the work has to be done from inside, through the floor, moving out for part of the job is sometimes advised.
Does underpinning need building control approval?
Yes, underpinning is building work and needs approval and inspections in England and Wales, a building warrant in Scotland, and council building control in Northern Ireland. Inspectors usually check the excavations before concrete is poured. We deal with building control as part of the job.
