Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Portstewart (BT55) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Leaks at bars or ridge
- Cappings lifted or rattling
- Corrosion at cut edges or fixings in coastal areas
Common causes we find
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
About Portstewart and the BT55 area
