Wall tie replacement in Chesham
Plenty of cavity-walled houses, in Chesham as elsewhere, were built when galvanised steel ties were standard, and those ties are now reaching the end of their life. A survey shows whether yours are sound, thinning or actively swelling and cracking the brickwork.

How do local ground conditions affect wall tie replacement in Chesham?
Postcode districts HP5 cover Chesham, a Buckinghamshire town of about 21,000 people. Neighbouring towns we cover: Amersham (2 miles), Berkhamsted (4 miles) and Rickmansworth (7 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. Across Buckinghamshire, most homes are market-town terraces, 1930s semis in the south, and large late-20th-century estates in Milton Keynes and Aylesbury.
What happens during wall tie replacement, step by step?
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.
What to look for before calling about wall tie replacement
- Horizontal cracks along mortar joints, repeating every few brick courses
- Outer brickwork bowing or bulging, often worst near the top
- Cracked render with a regular horizontal pattern

How we usually approach 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
Remedial tie installation
New stainless ties are drilled through the outer leaf into the inner leaf, then fixed by mechanical expansion or resin, depending on the masonry. They are placed to a set grid across each elevation, with extra ties around openings and at the edges. Holes are made good in matching mortar.
Best for: Walls where the original ties have failed or are missing
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.
Questions about wall tie replacement in Chesham
What is the price of wall tie replacement in Chesham?
Guide prices for wall tie replacement in Chesham 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 carry out wall tie replacement in Chesham?
Yes. We take enquiries from across Chesham, including HP5, and from nearby places such as Amersham and Berkhamsted. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Chesham 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 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.
