Wall tie replacement for Bangor properties

Bangor is among the towns we cover in Gwynedd, alongside Caernarfon, Porthmadog and Holyhead. Bangor is one of the main towns we cover in Gwynedd.

If your Bangor installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Bangor home is not always the insulation's fault, so the diagnosis comes before any extraction.

Local weather affects which walls can be filled. Parts of Gwynedd face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On the rules side, if cavity wall insulation follows in Bangor, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

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.
