EWI in Southport

Thermal upgrade systems that cut heat loss, improve EPC ratings and finish in a full render colour range.

EWI for Southport homes & commercial buildings

External Wall Insulation wraps a building in an insulation board finished in render, cutting heat loss through solid or poorly-insulated walls and improving its EPC rating without losing internal floor space. It's increasingly specified on social housing retrofit and decarbonisation programmes, as well as private refurbishment work.

We cover Southport and the wider Sefton Council area, working directly for homeowners and as a trade contractor for developers and main contractors locally.
