How do local ground conditions affect subsidence repairs in Fareham?
Fareham is in Hampshire and takes in postcode districts PO14, PO15, PO16. About 42,000 people live there. Nearby places we cover include Portsmouth (5 miles), Hedge End (7 miles) and Waterlooville (7 miles).
Hampshire 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 Hampshire, most homes are Victorian terraces in Portsmouth and Southampton, 1930s semis, and large post-war and new-build estates.

Which repair method suits a home in Fareham?
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
Remove the cause, then repair
Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.
Best for: Clay movement or drain leaks where the cause can be removed
What happens when we carry out subsidence repairs in Fareham?
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
- Wallpaper rippling or tearing where the wall meets the ceiling
- Cracks that open in summer and partly close again in winter
- Diagonal cracks wider at the top, running from window or door corners
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 Fareham: questions and answers
What is the price of subsidence repairs in Fareham?
Guide prices for subsidence repairs in Fareham start from about £2,800 per property, including VAT, on South East 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 Fareham?
Yes, Fareham is covered, along with postcode districts PO14, PO15, PO16. We also cover nearby Portsmouth and Hedge End.
Does the ground around Fareham cause cracking?
Central Hampshire is chalk, while the south around Portsmouth, Southampton and the New Forest fringe and the north-east around Farnborough sit on London Clay, Reading Beds and other clays and sands. The clay areas see seasonal movement near trees. 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 do I know if cracks are subsidence?
Subsidence cracks are usually tapered, run diagonally from door and window corners, and show on both faces of the wall. Fine vertical cracks in new plaster are more often shrinkage. An engineer’s inspection, sometimes with monitoring, is the reliable way to tell.
