Caernarfon: walls, weather and approvals
As well as Caernarfon itself, we quote in Llangefni, Bangor (Gwynedd) and Holyhead. It's roughly 8 miles from Caernarfon to Bangor (Gwynedd), the largest town in 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.
On older houses in Caernarfon, stripping old render often reveals mortar repairs that are best done before re-rendering.

Permissions in Wales
Householder rules in Wales are similar to England's: in Caernarfon, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
Welsh Building Regulations expect walls to be upgraded when a substantial area is renewed, and building control signs the work off.
Which new render should I choose?
On older solid walls, breathable lime or a mineral system is often safest. On sound modern masonry, silicone over a mesh base coat gives a durable, low-maintenance finish. If insulation is added, the finish is the one specified for the EWI system.

Re-rendering in Caernarfon: questions
How do I know if my render has failed?
Signs include cracks, hollow sound when tapped, bulging, pieces falling off, and damp patches inside behind cracked areas.
Do I need building control for re-rendering?
In England and Wales, re-rendering more than half of a wall's area — or more than a quarter of the whole building's envelope — is controlled work under Part L, so usually yes. We explain how it's handled in the quote.
Is it worth adding insulation?
On solid or concrete walls it's usually the most cost-effective time to do it, because access and preparation are already paid for.
Do you cover Caernarfon?
Yes — we survey and quote re-rendering in Caernarfon (LL55) and nearby Llangefni, Bangor (Gwynedd) and Holyhead, with a fixed written price before any work starts.
