If there is no Lichen present and we can reach your panels from the ground with our extendable brushes this will be £6 per panel.
If Lichen is present this will require a scaffold tower and a Lichen removal agent treatment as it is very difficult to remove and significantly increases the time it takes to complete the cleaning effectively. This is £15 per panel with lichen on plus £150 scaffold tower hire.
Once the Lichen has been removed if your panels are cleaned regularly they will not require a scaffold tower or treatment.
