Subsidence repairs in Bicester
Cracks in a house in Bicester are not always subsidence, and subsidence is not always serious. The first job is to find out what is moving and why, whether that is a leaking drain, a nearby tree or soft ground under shallow footings.

How do local ground conditions affect subsidence repairs in Bicester?
With roughly 34,000 people, Bicester spans postcode districts OX6, OX26 in Oxfordshire. Nearby places we cover include Oxford (11 miles), Banbury (14 miles) and Aylesbury (16 miles).
Shrinkable clay is widespread in Oxfordshire. Ground movement here is more often linked to soils, drains and trees than to mining. Across Oxfordshire, most homes are Cotswold stone villages, Victorian terraces in Oxford and Banbury, and large post-war and new-build estates around Didcot and Bicester.
What happens when we carry out subsidence repairs in Bicester?
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.
Written quote
We price the agreed repair and confirm a fixed price in writing once it is specified. If there is an insurance claim, we can price to the loss adjuster’s or engineer’s schedule instead of our own scope.
Repairs and making good
Cracks are stitched and repointed outside, plaster is renewed along the crack lines inside, and sticking doors are eased. Where the work needs it, we deal with building control and hand over the paperwork.
Signs you may need subsidence repairs
- Diagonal cracks wider at the top, running from window or door corners
- Fresh cracks showing on both the inside and outside of one wall
- A gap opening between the skirting board and the floor

Which repair method suits a home in Bicester?
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
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
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.
Subsidence repairs in Bicester: questions and answers

Is the ground in Oxfordshire prone to subsidence?
Oxfordshire's vales sit on Oxford, Kimmeridge and Gault Clays, among the more shrinkage-prone clays in England, with Cotswold limestone in the north-west and chalk downs in the south. Only an investigation can say why a particular building has moved.
Does subsidence always need underpinning?
No, most subsidence is repaired without underpinning. When a leaking drain is fixed or nearby vegetation is managed, the ground usually stabilises and the house needs only crack repairs. Foundation work is kept for movement that continues after the cause has gone.
How long should I wait before repairing subsidence cracks?
Usually until the cause has been dealt with and the engineer is satisfied that movement has stopped. On clay that can mean watching the house through a summer and a winter. Repairing too early risks the same cracks opening again.
