Methods for boundary and garden wall repairs
Repointing and minor repairs
Weak mortar is raked out and the wall repointed in a mortar that suits the bricks, and damaged bricks are replaced with matching ones. Loose copings are rebedded or replaced with a design that throws water clear of both faces. This is often enough for an upright wall.
Best for: Upright walls with weathered joints, loose copings or spalled bricks
Rebuilding a leaning section
The leaning or badly cracked section is taken down, sound bricks cleaned for reuse, and the wall rebuilt on a new footing at a suitable depth. A damp-proof course and a proper coping are added, and the new work is jointed to the sound wall either side.
Best for: Sections that lean, rock or have cracked right through

Site assessment
On site we check the lean with a level, look at the footing where it can be seen, note the bricks and mortar, and check for trees, soil loading and gate loads. If the wall turns out to be retaining soil, we treat it as a retaining wall.
Neighbour and notices
Where the wall is shared or on the line of junction in England and Wales, the Party Wall etc. Act 1996 may require notice before work starts. We can explain what is likely to be needed, and work is agreed with neighbours first.
Repair and rebuild
Sections are taken down, footings dug, and the wall rebuilt or repointed with a damp-proof course and coping. Reclaimed or matched bricks keep the wall consistent, and spoil and old materials are removed at the end.

Frequently asked questions
How much will boundary and garden wall repairs cost in Harpenden?
Guide prices for boundary and garden wall repairs in Harpenden start from about £315 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.
Do you cover Harpenden?
Yes, Harpenden is covered, along with postcode districts AL5. We also cover nearby St Albans and Luton.
Is the ground in Hertfordshire prone to subsidence?
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 boundary wall?
Responsibility depends on who owns the wall, which is shown in your title deeds and plans, or may be shared. A wall built on the line between two properties is often jointly owned. Check the deeds first and agree repairs with your neighbour, and in England and Wales check whether the Party Wall Act applies.
Is a leaning garden wall dangerous?
It can be, particularly a tall wall, a front wall by a pavement or one that moves when pushed. A slight lean that has not changed for years may be stable, but a wall leaning more each year should be kept clear and repaired before a storm finds it.
