Across Sunshine Coast Regional Council, QLD
This is the service page for window cleaning, and it does one job: it explains what an S & J window clean covers, what changes from one part of the Coast to another, and then sends you to the page for your suburb. Each of the six suburb pages is written from the glass conditions that suburb actually deals with, because a louvred highset on tank water at Beerwah and an Esplanade apartment carrying daily sea mist need different work. Pick your suburb below if you already know what you need, or read on for the parts that are the same everywhere.
Most people looking for a window cleaner have already tried doing it themselves and found the glass looked worse afterwards. That is usually not technique; it is the local conditions. Fine dust and salt both bind into a film that smears under a dry cloth, and mineral spotting needs dissolving rather than polishing. So we wash rather than dry-wipe, use a descaler with dwell time where sprinklers or tank water have marked the glass, take screens out and wash them rather than brushing dust deeper into the mesh, and flush the tracks. That is the same in every suburb; what differs is which of those problems is doing the damage.
