Why does the ground in Greater London matter for wall tie replacement?
Wandsworth takes in postcode districts including SW6, SW11, SW15, SW17, SW18, with about 330,000 residents. Nearby places we cover include Hammersmith and Fulham (3 miles), Lambeth (3 miles) and Kensington and Chelsea (3 miles).
Much of Greater London 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 Greater London, most homes are Victorian and Edwardian terraces with shallow footings, inter-war semis in the outer boroughs, and converted flats and mansion blocks.
What happens during wall tie replacement, step by step?
Tie survey
A metal detector locates the existing ties and shows their pattern. Small holes are then drilled at sample points and a borescope passed into the cavity to see the tie condition, type and embedment. The holes are made good afterwards.
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.
What to look for before calling about wall tie replacement

How we usually approach wall tie replacement
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
Isolating the old ties
Where the old ties are swelling and cracking the brickwork, fitting new ties alone may not stop further damage. Each old tie can be isolated, usually by cutting it through within the cavity or sleeving its outer end, so it can no longer lift the outer leaf as it continues to corrode.
Best for: Thick mild steel ties still causing horizontal cracking
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 Wandsworth
How much should I budget for wall tie replacement in Wandsworth?
Guide prices for wall tie replacement in Wandsworth start from about £2,250 per house, including VAT, on London rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Greater London crack?
Most of Greater London sits on London Clay, among the most shrinkage-prone ground in the UK, with river gravels along the Thames. Subsidence claims here are among the most frequent in the country, especially after dry summers and near street and garden trees. Only an investigation can say why a particular building has moved.
Do all walls of the house need new ties?
Not necessarily, because ties often fail on one exposed elevation long before the others. The survey checks each wall, and the quote covers only the elevations where ties have failed or are close to it. Sheltered walls may simply be noted for future checks.
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.
