Before we quote 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.
For Gwynedd homeowners matching a new extension to an existing rendered house, we compare monocouche and silicone samples first.

Approvals in Wales
Permitted development rules for houses in Wales are similar to England's: a similar-appearance finish on a house is often permitted, while conservation areas, National Parks, Areas of Outstanding Natural Beauty, flats, commercial buildings and listed buildings need permission or consent. Your local planning authority has the final word.
The Building Regulations as they apply in Wales treat insulating or re-rendering more than half of a wall's area, or more than a quarter of the building's whole envelope, as renovating a thermal element, with Approved Document L (Wales) setting the target. Building control is involved before work starts.
Why does monocouche sometimes look patchy?
Colour variation (often called shading) can appear if it's applied in poor weather, on walls with uneven suction, or in sections on different days. Working an elevation in one go in suitable conditions keeps the colour even.

Monocouche render in Gwynedd: questions
Does monocouche need painting?
No — it's through-coloured. Cleaning every few years keeps it looking fresh.
How long does monocouche last?
Typically 20 years or more on a suitable wall, depending on exposure and detailing.
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
Do you cover all of Gwynedd?
Yes. We survey and quote monocouche render across Gwynedd, including Bangor (Gwynedd), Holyhead, Caernarfon, Llangefni.
