Bifold doors are generally very low maintenance. They will only need infrequent cleaning and occasionally you may need to oil the track mechanism to ensure smooth opening. Speak to your installer and ask about general housekeeping and long lasting treatments.
Ravenglass
Ravenglass is a tiny coastal village and natural harbour in Cumbria, England approximately halfway in between Barrow-in-Furness as well as Whitehaven. Historically in Cumberland, it is the only seaside town in the Lake District National Park. It lies at the estuary of three rivers: the Esk, Mite as well as Irt. The hamlet of Saltcoats lies north of the River Mite.
