What is the ground like in Buckinghamshire?
Marlow is in Buckinghamshire and takes in postcode districts SL7. About 18,000 people live there. Neighbouring towns we cover: Maidenhead (4 miles), High Wycombe (4 miles) and Slough (9 miles).
Buckinghamshire 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. Typical buildings in Buckinghamshire: Market-town terraces, 1930s semis in the south, and large late-20th-century estates in Milton Keynes and Aylesbury.
What to expect when we carry out retaining wall repairs
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.
Site assessment
On site we measure height and lean, check the drainage and the ground at the top and bottom, and look at access for digging out. Walls that support a drive, path or building, or retain more than a modest height, are referred to an engineer.
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.
Is it time for retaining wall repairs? Common signs

Repair options we may recommend
Structural repair and partial rebuild
A leaning or bulging section is taken down, the soil behind dug out and supported, and the wall rebuilt on a new footing with drainage and, where specified, reinforcement tied into the sound wall either side. The engineer’s design sets footing size and wall thickness.
Best for: A section that has moved while the rest stays sound
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
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.
Your retaining wall repairs questions
What is the price of retaining wall repairs in Marlow?
Guide prices for retaining wall repairs in Marlow 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.

Does the ground around Marlow cause cracking?
The Chilterns are chalk with clay-with-flints on the tops, while the Vale of Aylesbury and Milton Keynes sit on Gault, Kimmeridge and Oxford Clays and glacial till. The vale clays are prone to seasonal shrinkage near trees. Only an investigation can say why a particular building has moved.
Can a bulging retaining wall be saved?
Sometimes, if the bulge is small, the wall is low and the cause is mainly poor drainage. Improving drainage and repairing the face may stop further movement. A wall that has bulged a lot, cracked through or moved at its base usually needs that section rebuilding on a proper footing.
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.
