Across Hertfordshire, most homes are garden-city houses in Letchworth and Welwyn, 1930s semis, Victorian terraces and post-war new-town estates.

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.
Written quote
You receive a no-obligation written quote covering demolition, excavation, temporary support, the footing, the new or repaired wall, drainage and spoil removal. It becomes a fixed price in writing once the repair is specified.
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
- Ground cracking or sinking along the top of the wall
- Bricks or blocks pushed out of line, or coping stones sliding off
- Horizontal or stepped cracks running along the face of the wall

Methods for retaining wall repairs
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
Temporary support and reducing load
While a repair is designed and programmed, a dangerous wall may be propped, or soil and loads near the top removed to reduce the push. Moving parked cars or a shed back from the wall is sometimes the simplest first step.
Best for: Walls that are moving now and need making safe
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 Hemel Hempstead?
Guide prices for retaining wall repairs in Hemel Hempstead start from about £525 per wall, 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.
Can you survey a property in Hemel Hempstead?
Yes. We take enquiries from across Hemel Hempstead, including HP1, HP2, HP3, and from nearby places such as Berkhamsted and St Albans. Send photos for a free initial view and we will tell you what happens next.
Why do houses in Hertfordshire crack?
South Hertfordshire around Watford, Borehamwood and Potters Bar is London Clay, while the north and west are chalk with clay-with-flints and the east has boulder clay. The clay areas are prone to seasonal subsidence near trees. Only an investigation can say why a particular building has moved.
Who is responsible for a retaining wall between two properties?
Usually the owner of the higher ground, because the wall holds up their land, but it depends on your title deeds and how the wall came to be built. Check the deeds first, take advice if it is unclear, and agree the repair with your neighbour before work starts.
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.
