Wall tie replacement in Amersham
Horizontal cracking on a Amersham house is easy to mistake for subsidence. Rusting wall ties leave a much more regular pattern, though, and telling the two apart early saves time, money and an unnecessary insurance claim.

Why does the ground in Buckinghamshire matter for wall tie replacement?
Postcode districts HP6, HP7 cover Amersham, a Buckinghamshire town of about 22,000 people. If you are just outside Amersham, we also cover Chesham (2 miles), Gerrards Cross (6 miles) and High Wycombe (6 miles).
Shrinkable clay is widespread in Buckinghamshire. Ground movement here is more often linked to soils, drains and trees than to mining. Across Buckinghamshire, most homes are market-town terraces, 1930s semis in the south, and large late-20th-century estates in Milton Keynes and Aylesbury.
Methods for wall tie replacement
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
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

Report and quote
You receive a written summary of what the survey found on each elevation, which walls need new ties, whether old ties should be isolated or removed, and a no-obligation written quote with scaffold shown separately.
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.
Symptoms that point to wall tie replacement
- Outer brickwork bowing or bulging, often worst near the top
- Mortar joints that look wider or opened up on one elevation
- A house built before the 1980s on an exposed or coastal site

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.
Frequently asked questions
How much will wall tie replacement cost in Amersham?
Guide prices for wall tie replacement in Amersham 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.
Do you cover Amersham?
Yes. We take enquiries from across Amersham, including HP6, HP7, and from nearby places such as Chesham and Gerrards Cross. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Buckinghamshire prone to subsidence?
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 wall ties be replaced on a rendered house?
Yes, new ties can be fitted through render, with each drill hole made good afterwards. The repairs can show on painted render, so redecoration of the affected elevation is often worth including. Render can also hide the cracking pattern, so a survey matters more.
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.
