- Local Authorities – district and borough council buildings and housing.

Roofing Across Sussex
Our teams work across northern Sussex – Crawley, Horsham, East Grinstead and the towns along the A23/M23 corridor – with reach further south into the county for planned and contract works. The Gatwick area in particular has a dense commercial and industrial base that suits our large-roof and planned-maintenance capability.
Much of our recent project work sits in neighbouring Surrey, close to the Sussex border – including a flat roof refurbishment at Warlingham Park School and a Bauder bitumen flat roof replacement in Lingfield, a village on the Surrey–Sussex boundary. These reflect the commercial, school and residential work we deliver across the wider region. View our full project portfolio
