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

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

From first photo to finished repair

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.
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.

Rules for wall tie replacement in Northern Ireland

In Northern Ireland, minor repairs usually need no approval, but structural work comes under the Building Regulations (Northern Ireland) 2012 and council building control. There is no Party Wall Act in Northern Ireland.

Frequently asked questions

How much should I budget for wall tie replacement in Limavady?

Guide prices for wall tie replacement in Limavady start from about £1,600 per house, including VAT, on Northern Ireland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Can you survey a property in Limavady?

We do. Limavady and the surrounding area are covered, including nearby Coleraine and Derry. A free initial assessment from your photos is the first step.

Why do houses in County Londonderry crack?

County Londonderry has basalt, older hard rock and glacial deposits, with soft river ground along the Foyle and Bann. Only an investigation can say why a particular building has moved.

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.

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.
