Wall tie replacement in St Helens
The first clue to failing wall ties in St Helens is usually a crack pattern: fine horizontal lines every few courses on one elevation. We confirm what is happening inside the cavity with a metal detector and borescope before recommending any new ties.

Why does the ground in Merseyside matter for wall tie replacement?
St Helens is in Merseyside and takes in postcode districts WA9, WA10, WA11. About 180,000 people live there. Neighbouring towns we cover: Prescot (3 miles), Ashton-in-Makerfield (4 miles) and Huyton (5 miles).
Clay soils are found in parts of Merseyside. Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Merseyside: Victorian terraces and villas, inter-war council estates and post-war semis.
What to expect when we carry out wall tie replacement
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.
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.
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.

Repair options we may recommend
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
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.
Your wall tie replacement questions
How much will wall tie replacement cost in St Helens?
Guide prices for wall tie replacement in St Helens start from about £1,750 per house, including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover St Helens?
We do. St Helens and the surrounding area are covered, including nearby Prescot and Ashton-in-Makerfield. A free initial assessment from your photos is the first step.
Is the ground in Merseyside prone to subsidence?
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. Only an investigation can say why a particular building has moved.
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.
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.
