Underpinning in Cirencester
Before any underpinning goes ahead on a Cirencester property, building control has to approve the design and inspect the excavations. Where the wall is shared, party wall notices may be needed too in England and Wales, so allow time for paperwork before the dig.

Is Gloucestershire prone to ground movement?
Cirencester (GL7) has around 20,000 residents and sits in Gloucestershire. Nearby, we also cover Stroud (10 miles), Cheltenham (13 miles) and Swindon (14 miles).
Gloucestershire has a mix of ground, with clay in some places and firmer rock in others. Parts of Gloucestershire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Gloucestershire: Cotswold stone cottages, Regency terraces in Cheltenham, and brick estates around Gloucester.
Methods for underpinning
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
Mass concrete underpinning
The traditional method. Short sections under the wall are dug out in a set sequence, usually about a metre at a time, and filled with concrete before the next section is opened. It suits moderate depths and good access, and it needs little specialist plant.
Best for: Shallow failures on firm ground found at moderate depth
From first photo to finished repair
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.
Fixed written price
With the design in hand we confirm a fixed price in writing, setting out the method, the length of wall, access arrangements and the making good. For insurance work we can price to the loss adjuster’s or engineer’s schedule.
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.
Symptoms that point to underpinning
- Cracks that keep widening after the drains have been repaired
- Floors sloping noticeably towards one external wall
- A large tree nearby that cannot be removed or reduced

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.
Frequently asked questions
What is the price of underpinning in Cirencester?
Guide prices for underpinning in Cirencester 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.
Do you carry out underpinning in Cirencester?
Yes. We take enquiries from across Cirencester, including GL7, and from nearby places such as Stroud and Cheltenham. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Cirencester cause cracking?
The Severn vale around Gloucester, Cheltenham and Tewkesbury is Lias and Mercia Mudstone clay, the Cotswolds are limestone, and the Forest of Dean has a historic coalfield. Parts of South Gloucestershire around Kingswood also lie on old Coal Measures. Only an investigation can say why a particular building has moved.
Will underpinning affect selling my house?
It needs explaining to buyers, but a properly documented scheme is far better than unresolved movement. Keep the engineer’s design, the building control completion certificate and any insurance paperwork. Lenders and surveyors will usually ask for these before agreeing a sale.
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.
