Wall tie replacement for Porthmadog properties
Our Gwynedd coverage takes in Porthmadog (LL49) and nearby Caernarfon and Bangor. It is roughly 19 miles south of Bangor.
Where a Porthmadog wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up. If your Porthmadog installation has a guarantee, we check it first; the guarantee route may cover the work.
Before any material is chosen, exposure is checked. 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 compliance, if cavity wall insulation follows in Porthmadog, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Ties and cavity insulation
Ties should be checked before a cavity is filled. Fitting remedial ties does not normally stop a cavity being insulated later, and we can do both in one visit. Where cracking suggests movement, we recommend a structural engineer's view first.
