Homes and walls in Caernarfon
As well as Caernarfon itself, we quote in Llangefni, Bangor (Gwynedd) and Holyhead. Caernarfon sits around 8 miles from Bangor (Gwynedd). North Wales has many solid stone and slate-built homes, Victorian seaside terraces and post-war council estates.
Parts of Gwynedd fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
Low-level impact damage near drives and bins is a typical EWI repair, and we fix it in Caernarfon with compatible materials.

EWI repairs in Caernarfon: questions
Can damaged EWI be patched?
Yes, provided the board behind is dry and sound. Wet or crushed board is cut out and replaced.
Will the repair be visible?
Usually slightly, because the existing finish has weathered. A recoat of the elevation evens it out.
My EWI was installed under a grant — who repairs it?
First check the guarantee paperwork and contact the original installer or guarantee provider. If that route isn't available, we can quote.
Do you cover Caernarfon?
Yes — we survey and quote EWI repairs in Caernarfon (LL55) and nearby Llangefni, Bangor (Gwynedd) and Holyhead, with a fixed written price before any work starts.
