Subsidence repairs in Bognor Regis
Subsidence in Bognor Regis, as anywhere in West Sussex, usually comes back to the ground beneath the footings: clay drying out, a drain leaking or roots taking water. Knowing which applies decides whether the repair is a few days of crack work or a longer foundation scheme.

What should you know about the ground under Bognor Regis?
Bognor Regis, West Sussex: about 64,000 residents across postcode districts PO21, PO22. Nearby places we cover include Chichester (6 miles), Littlehampton (6 miles) and Emsworth (12 miles).
Shrinkable clay is widespread in West Sussex. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in West Sussex: Wealden cottages, 1930s semis and bungalows on the coast, and new-town estates in Crawley.
Which repair method suits a home in Bognor Regis?
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
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 Bognor Regis?
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
- A gap opening between the skirting board and the floor
- Cracks that open in summer and partly close again in winter

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 Bognor Regis: questions and answers
How much should I budget for subsidence repairs in Bognor Regis?
Guide prices for subsidence repairs in Bognor Regis 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.
Can you survey a property in Bognor Regis?
Yes. We take enquiries from across Bognor Regis, including PO21, PO22, and from nearby places such as Chichester and Littlehampton. Send photos for a free initial view and we will tell you what happens next.
Why do houses in West Sussex crack?
North West Sussex around Crawley and Horsham sits on Weald Clay, the South Downs are chalk, and the coastal plain has brickearth and gravels. The Weald Clay is prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.
Do you need to visit before giving a price?
Not at first. We give a free initial assessment from your photos or a call, and a no-obligation written quote once the scope is clear. A fixed price follows in writing once the repair is specified, which normally needs a survey.
Can I sell a house that has had subsidence?
Yes, though buyers and lenders will want paperwork. Keep the engineer’s report, monitoring results, the repair specification and any building control sign-off. A repaired house shown to be stable is far easier to sell than one with an open problem.
