Homes and walls 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.
Low-level impact damage near drives and bins is a typical EWI repair, and we fix it in Gwynedd with compatible materials.

Wales: planning and regulations
Repairs, cleaning and like-for-like patching don't usually need planning permission or building control. If repairs grow into re-rendering more than half of a wall, Building Regulations energy rules can apply.
Listed buildings are the exception: even small external repairs can need listed building consent, so tell us if your property is listed.
How is damaged EWI repaired?
The damaged area is cut back to sound render and board. Wet or crushed insulation is replaced, a new base coat with overlapping mesh is applied, then primer and a matching finish. The repair overlaps the existing mesh so it's reinforced like the original.

EWI repairs in Gwynedd: questions
Why is my EWI cracking?
Common causes are missing movement joints, poor mesh overlap, fixing problems or movement in the wall. We look for the cause rather than filling the crack.
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 all of Gwynedd?
Yes. We survey and quote EWI repairs across Gwynedd, including Bangor (Gwynedd), Holyhead, Caernarfon, Llangefni.
Do I need planning permission 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. We check your address before quoting.
