Why does the ground in Hampshire matter for wall tie replacement?

Central Hampshire is chalk, while the south around Portsmouth, Southampton and the New Forest fringe and the north-east around Farnborough sit on London Clay, Reading Beds and other clays and sands. The clay areas see seasonal movement near trees.

Ground movement here is more often linked to soils, drains and trees than to mining. Across Hampshire, most homes are Victorian terraces in Portsmouth and Southampton, 1930s semis, and large post-war and new-build estates.

What to look for before calling about wall tie replacement

  • A house built before the 1980s on an exposed or coastal site
  • Cracked render with a regular horizontal pattern
  • Outer brickwork bowing or bulging, often worst near the top
  • The roof edge or verge lifting slightly above the brickwork

How we usually approach wall tie replacement

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

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

What happens during wall tie replacement, step by step?

  1. 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.

  2. 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.

  3. 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.

Do you need approval 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 Hampshire

Is the ground in Hampshire prone to subsidence?

Central Hampshire is chalk, while the south around Portsmouth, Southampton and the New Forest fringe and the north-east around Farnborough sit on London Clay, Reading Beds and other clays and sands. The clay areas see seasonal movement near trees. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.

How much will wall tie replacement cost in Hampshire?

On South East rates, wall tie replacement starts from about £2,000 per house, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

Will a mortgage lender accept wall tie replacement?

Lenders generally accept properly carried out tie replacement, but they may want to see the survey, the quote or a record of the completed work. If a valuation has flagged wall ties, a written report and itemised quote are usually what the lender or buyer needs next.

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.

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.
