Is West Sussex prone to ground movement?
We cover Burgess Hill and its postcode districts RH15, part of West Sussex, with a population of roughly 31,000. Nearby places we cover include Haywards Heath (3 miles), Lewes (8 miles) and Brighton (9 miles).
Much of West Sussex sits on clay that shrinks in dry summers and swells in wet winters. 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.
Methods for retaining wall repairs
Rebuilding on new footings
Where the whole wall is failing, it is replaced with a new retaining wall on a properly sized footing, with free-draining backfill, a membrane, weep holes and a drain at the base. Reinforced blockwork faced in brick or stone is common, so the wall matches its surroundings.
Best for: Walls failing along their length, or retaining significant height
Drainage and minor repairs
Blocked weep holes are cleared or new ones drilled, and where practical a drainage layer is formed behind the wall with an outlet at its base. Loose copings are rebedded, open joints repointed and a few damaged bricks replaced. For a low wall that has not moved much, this can be enough.
Best for: Low walls that are damp or slightly weathered but still upright
From first photo to finished repair
Photos and measurements
Send photos of the whole wall from the front and the end, so any lean shows, plus close-ups of cracks and weep holes. Tell us roughly how tall it is and what sits at the top, such as lawn, patio, drive or a building.
Engineer’s design
Where the wall needs it, an independent chartered structural engineer is appointed to design the repair or new wall, including footing, thickness, reinforcement and drainage. We can arrange this, and the design forms the basis of the quote.
Build and drain
The failing section is taken down, the soil supported in short lengths, and the footing cast. The wall is rebuilt with drainage behind it, backfilled with free-draining material, and building control inspects where the work needs it.
Symptoms that point to retaining wall repairs
- Horizontal or stepped cracks running along the face of the wall
- No weep holes, or weep holes that never seem to drain
- Water seeping through joints, or white salt staining, after rain

Rules for retaining wall 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.
Frequently asked questions
How much should I budget for retaining wall repairs in Burgess Hill?
Guide prices for retaining wall repairs in Burgess Hill start from about £560 per wall, 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 Burgess Hill?
We do. Burgess Hill and the surrounding area are covered, including nearby Haywards Heath and Lewes. A free initial assessment from your photos is the first step.
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.
How long does a retaining wall rebuild take?
Drainage and minor repairs usually take a day or two. Rebuilding a garden retaining wall on new footings typically takes one to three weeks, depending on its length, height, access for digging and any wait for the engineer’s design or inspections.
Is a leaning retaining wall dangerous?
It can be, especially if the lean is getting worse, the wall is tall, or there is a path, drive or building next to it. A wall that has leaned slightly for decades may be stable, but one that has moved recently should be kept clear and assessed soon.
