What should you know about the ground under Cambridge?
Cambridge is in Cambridgeshire and takes in postcode districts CB2, CB4. About 150,000 people live there. Nearby, we also cover Royston (12 miles), St Ives (12 miles) and Newmarket (13 miles).
Cambridgeshire is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. Across Cambridgeshire, most homes are Victorian terraces in Cambridge and Peterborough, fen-edge cottages, and extensive post-war and new-build estates.

Which repair method suits a home in Cambridge?
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
What happens when we carry out subsidence repairs in Cambridge?
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.
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.
Signs you may need 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
- Wallpaper rippling or tearing where the wall meets the ceiling
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 Cambridge: questions and answers
What is the price of subsidence repairs in Cambridge?
Guide prices for subsidence repairs in Cambridge start from about £2,600 per property, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out subsidence repairs in Cambridge?
Yes, Cambridge is covered, along with postcode districts CB2, CB4. We also cover nearby Royston and St Ives.
Does the ground around Cambridge cause cracking?
Gault Clay underlies much of the Cambridge area and Oxford Clay the west of the county around Peterborough and Huntingdon, while the northern fens are peat and silt that can shrink as they dry. Both clay and peat ground can move with the seasons. 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.
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.
