Is Your Property Suitable for External Wall Insulation in West Wickham?
Many homes in West Wickham — particularly older properties with solid external walls — are well suited to external wall insulation. Where cavity insulation isn’t possible or effective, EWI provides a continuous thermal layer to the outside of the building, improving warmth while leaving internal space untouched.
By insulating externally, draughts are reduced, surface temperatures are stabilised, and the risk of condensation and damp can be significantly lowered when the system is correctly specified and installed.
