Wall tie replacement for Durham properties

If your property is in Durham or the DH1 district or nearby Chester-le-Street, Stanley and Bishop Auckland, it is within our County Durham coverage. Durham is one of the main towns we cover in County Durham.

We never cold-call in Durham or anywhere else, and we do not work with doorstep claims companies. Damp in an insulated Durham home is not always the insulation's fault, so the diagnosis comes before any extraction.

Exposure matters for every cavity wall. County Durham has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

On compliance, if cavity wall insulation follows in Durham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Signs of wall tie failure

Horizontal cracks in mortar joints at regular vertical intervals, bulging brickwork, or lifting of the roof verge. Older galvanised ties, especially in walls built before the 1980s, are the usual suspects.
