Repointing and pre-insulation repairs for Caernarfon properties
Caernarfon sits in Gwynedd, around 6 miles south-west of Bangor. We work across the LL55 district, including nearby Bangor, Porthmadog and Holyhead.
Where a Caernarfon 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. Damp in an insulated Caernarfon 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 Caernarfon, 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.
