Wall tie replacement in Sutton
On exposed sites around Sutton, the elevation facing the weather often loses its wall ties first. Remedial stainless ties reconnect the two leaves, and the old ties are isolated or removed where they are still pushing the brickwork apart.

Repair options we may recommend
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
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.
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
What is the price of wall tie replacement in Sutton?
Guide prices for wall tie replacement in Sutton 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.
Do you carry out wall tie replacement in Sutton?
We do. Sutton and the surrounding area are covered, including nearby Ewell and Banstead. A free initial assessment from your photos is the first step.
Does the ground around Sutton cause cracking?
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.
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.
Which houses are most at risk of wall tie failure?
Cavity-walled houses built before the 1980s are most at risk, especially those with mild steel ties, black ash mortar or an exposed position. Coastal and hilltop houses, and elevations facing the prevailing weather, tend to fail first.
