Local considerations in Newport (Gwent)
Surveys in Newport (Gwent) also cover the surrounding NP20 district and towns such as Risca and Cwmbran. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across Gwent: 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 one half of a pair in Newport (Gwent) is insulated and the other isn't, we detail the boundary so the neighbour can join later.

Permissions in Wales
Householder rules in Wales are similar to England's: in Newport (Gwent), 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.
Does EWI fix mortgage problems with PRC houses?
Not on its own. Some precast reinforced concrete (PRC) house types were designated defective, and many lenders want a certified structural repair before they will lend. Insulation and render over the outside is not that repair. Other types, such as Wimpey no-fines, are generally treated differently. If mortgageability matters, speak to your lender or a surveyor before booking any work.

Non-traditional houses in Newport (Gwent): questions
Can you insulate a Wimpey no-fines house?
Yes. No-fines houses have solid poured-concrete walls with no cavity, so EWI is the usual route. The survey checks the concrete condition first.
What if my neighbour isn't insulating?
We finish the system neatly at the boundary with a closing detail so the neighbouring house isn't affected and can be joined later.
Will EWI make my house mortgageable?
It can make a house more attractive and better insulated, but it does not replace a certified structural repair where a lender requires one. Ask your lender before relying on it.
Do you cover Newport (Gwent)?
