If you are considering aluminium doors, windows or pantry cupboards a company called NS Aluminium. They show powder coated quality aluminium in their sales demo to you. They even use their car key to show it cannot be scratched. But when they come to install they use cheap spray painted aluminium and you can detect it because they easily scratch with a key. Beware! I caught them out and cancelled their work. Then they promised to bring genuine material and began to install. But work was shoddy and poor quality. They had left gaps beteeen top and bottom of doors and windows. For toilets and befroom doors they installed doors with transparent glass. Refused to come and inspect the dodgy work of their team. Phone calls were never answered. They had taken a huge advance to start the work and we are now demanding half back but they are not responding. Beware!
