Gwynedd: walls, weather and approvals
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.
If you're comparing quotes in Gwynedd, the written specification makes it easier to compare like for like.

Wales: planning and regulations
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.
What happens during the survey?
We measure each elevation, photograph the details that affect the job, check the wall construction and look for damp, cracking and loose render. Ground levels and the damp-proof course are recorded so the system starts in the right place. Eaves depth, window cills, flues, meters, soil pipes, satellite dishes and lights are all noted because each one needs a detail.
