Brick slip EWI in Ashford, Kent: questions
Do I need planning permission for external wall insulation in Ashford in Kent?
On a house, external wall insulation is usually permitted development if the finish looks similar to the existing walls. Render or cladding on a house in a conservation area, National Park, National Landscape (AONB), the Broads or a World Heritage Site needs planning permission. Flats and maisonettes have no householder permitted development rights, listed buildings need listed building consent, and an Article 4 direction can remove rights locally.
Do you cover Faversham as well as Ashford in Kent?
Yes. From Ashford in Kent we also cover Faversham, Canterbury and Folkestone, and the rest of Kent.
Which EWI system suits homes in Ashford in Kent?
It depends on the walls. Most brick houses in Ashford in Kent suit EPS with silicone render; older stone or lime-built walls suit wood fibre or insulating lime render; and blocks need mineral wool. The free survey recommends one and explains why.
