UPVC, timber and aluminium window and conservatory installation and specialism.
Eighteen firms offer windows and UPVC, with 5 dedicated to it and 5 more for whom it is a main trade. Most of the rest fold it into broader building work, or offer it as a side service. Vale holds 7, and St Sampson 5. Swan Joinery Ltd, founded in 1980, is the earliest here. —
