What we look for in Colwyn Bay
Surveys in Colwyn Bay also cover the surrounding LL29 district and towns such as Llandudno and Rhyl. Colwyn Bay is about 35 miles from Wrexham. North Wales has many solid stone and slate-built homes, Victorian seaside terraces and post-war council estates.
Exposure to wind-driven rain varies across Clwyd: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
Where a property in Colwyn Bay is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

Wales: planning and regulations
Internal insulation rarely needs planning permission, but in England and Wales insulating or replastering more than half of a wall's area involves building control, and listed buildings need consent for internal changes that affect their character.
What are the risks with internal insulation?
Insulating inside makes the masonry colder, so moisture risk rises. Weak points are where floor joists bear into the wall, window reveals and corners. A condensation risk check for the build-up, a continuous vapour control layer where specified, and returning insulation into reveals deal with most of it.
