Wall tie replacement in Merseyside

We arrange surveys and price wall tie replacement throughout Merseyside. Merseyside has a mix of ground, with clay in some places and firmer rock in others, and we take that into account before recommending a method.

How do local ground conditions affect wall tie replacement in Merseyside?

Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places.

Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Merseyside: Victorian terraces and villas, inter-war council estates and post-war semis.

Methods for wall tie replacement

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

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

  1. 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.

  2. 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.

  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.

Symptoms that point to wall tie replacement

  • Cracked render with a regular horizontal pattern
  • Outer brickwork bowing or bulging, often worst near the top
  • Horizontal cracks along mortar joints, repeating every few brick courses
  • A house built before the 1980s on an exposed or coastal site

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.

Frequently asked questions

Why do houses in Merseyside crack?

Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places. Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will wall tie replacement cost in Merseyside?

On North West rates, wall tie replacement starts from about £1,750 per house, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

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.

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.
