Repointing and pre-insulation repairs for Porthmadog properties
Porthmadog is among the towns we cover in Gwynedd, alongside Caernarfon and Bangor. It is about 19 miles south of Bangor.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Porthmadog properties, so you can choose who fixes them. We never cold-call in Porthmadog or anywhere else, and we do not work with doorstep claims companies.
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.
As for paperwork, 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.

Why repairs come first
Energy Saving Trust advice is to fix brickwork, pointing, roofs, gutters and downpipes before filling. A filled cavity is less forgiving of a wet outer leaf than an empty one, so we price repairs separately and you choose who carries them out.
