The workshop
A factory unit in Guerreiros. A man of his word.
JB Alumínios is Sr. João's aluminium joinery workshop in Pavilhão D, Rua Combatentes do Ultramar, São Sebastião de Guerreiros. The profiles are cut, assembled and glazed here, for the opening they will go into.
Customers keep saying the same three things: the deadline was kept — even when they were demanding about it — the price beat the other quotes, and what was asked for is what arrived.
Visits Monday to Friday, 9:00–18:00 — closed at weekends. Call before you come so the right person is at the workshop.
