Is Buckinghamshire prone to ground movement?
Gerrards Cross, Buckinghamshire: about 21,000 residents across postcode districts SL9, UB9. Neighbouring towns we cover: Rickmansworth (5 miles), Slough (6 miles) and Hillingdon (6 miles).
Much of Buckinghamshire 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. What you mostly find across Buckinghamshire: market-town terraces, 1930s semis in the south, and large late-20th-century estates in Milton Keynes and Aylesbury.

Repair options we may recommend
Partial rebuild of the outer leaf
If a section of the outer leaf has bulged too far to be tied back, it is carefully taken down and rebuilt with new ties built in as the work goes up. This is uncommon, and is usually limited to a gable top, a parapet or a panel under a window.
Best for: Outer leaf too distorted to tie back safely
Removing old ties and rebedding
On badly cracked elevations the old ties are cut out from the outer face, the joints raked and rebedded, and the brickwork repointed. It is more work than isolation but removes the source of expansion entirely. An engineer or the survey report usually specifies where this is needed.
Best for: Elevations with severe cracking or lifting
What to expect when we carry out wall tie replacement
Access
Ties are fitted across the whole of each affected elevation, so scaffold or a tower is usually needed above ground floor. We plan access around conservatories, extensions, neighbours’ land and any parking that must be suspended.
Install the new ties
New stainless ties are drilled and fixed to the specified grid, with closer spacing around windows, doors and the roofline. Sample ties can be pull-tested to confirm they are holding in your particular brick and block.
Deal with the old ties and make good
Old ties are isolated or removed where the report calls for it, cracked joints are raked out and repointed, and drilled holes are filled in matching mortar. A written note of tie positions and findings goes in your property file.
Is it time for wall tie replacement? Common signs
- Horizontal cracks along mortar joints, repeating every few brick courses
- A house built before the 1980s on an exposed or coastal site
- Mortar joints that look wider or opened up on one elevation
Rules for wall tie replacement in England
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.
Your wall tie replacement questions
How much should I budget for wall tie replacement in Gerrards Cross?
Guide prices for wall tie replacement in Gerrards Cross start from about £2,000 per house, 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 Gerrards Cross?
Yes, Gerrards Cross is covered, along with postcode districts SL9, UB9. We also cover nearby Rickmansworth and Slough.
Why do houses in Buckinghamshire crack?
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.
Is wall tie failure covered by insurance?
Usually not, because insurers treat it as gradual deterioration. Damage caused by a sudden event, such as part of a wall collapsing in a storm, may be treated differently under some policies. Check your policy wording, and tell your insurer if you are unsure.
How do I know if my wall ties have failed?
The clearest sign is horizontal cracking in the mortar joints repeating every few courses, often with a bulge or a lifted roofline. Wire ties can fail with no cracking at all, so a tie survey with a metal detector and borescope is the only reliable check.
