Inter-war homes and quiet commuter streets
Potters Bar grew quickly once the railway arrived, and most of its houses date from the 1930s onwards.
Darkes Lane, Oakmere and the streets around the station have inter-war semis with bay windows, while Little Heath, Bentley Heath and Brookmans Park have larger detached homes. Many have been extended, with new bathrooms, kitchens and bifold doors, all of which rely on good sealant.
Flats near the High Street, offices off the Great North Road and the commercial units along Cranborne Road add building sealant work for owners and builders.
Wyllyotts Centre, the Furzefield sports area and the busy Darkes Lane shops serve a close community. Many semis here had their original crittall-style steel windows replaced decades ago, and those first uPVC frames are now ready for new perimeter joints.

Sealant for extensions and bifold doors
Extensions bring new junctions: frame to brick, roof to wall, glass to aluminium. Each needs a sealant that suits the materials and the movement expected.
We use low-modulus silicone and polyurethane sealants, fit backer rod where joints are deep and colour-match to anthracite, white or timber-effect frames.
