Wall tie replacement in Dorking

Horizontal cracking on a Dorking house is easy to mistake for subsidence. Rusting wall ties leave a much more regular pattern, though, and telling the two apart early saves time, money and an unnecessary insurance claim.

Is Surrey prone to ground movement?

Dorking (KT23, RH4) has around 18,000 residents and sits in Surrey. If you are just outside Dorking, we also cover Leatherhead (4 miles), Redhill (7 miles) and Cobham (8 miles).

Shrinkable clay is widespread in Surrey. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Surrey: Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.

Methods for wall tie replacement

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

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

From first photo to finished repair

  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. 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.

Symptoms that point to wall tie replacement

  • The roof edge or verge lifting slightly above the brickwork
  • Horizontal cracks along mortar joints, repeating every few brick courses
  • Cracked render with a regular horizontal pattern

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.

Frequently asked questions

How much will wall tie replacement cost in Dorking?

Guide prices for wall tie replacement in Dorking start from about £2,000 per house, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you cover Dorking?

Yes. We take enquiries from across Dorking, including KT23, RH4, and from nearby places such as Leatherhead and Redhill. Send photos for a free initial view and we will tell you what happens next.

Is the ground in Surrey prone to subsidence?

North Surrey sits on London Clay, the south on Weald Clay, with chalk along the North Downs and sands in the west. Large gardens with mature trees on clay make seasonal subsidence a familiar problem. Only an investigation can say why a particular building has moved.

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.

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.
