I probably did myself no favours as with the size of the building and how busy i am I first of all said that it needs a cherry picker and pressure washer.
But then thought that it could be a nice job (£) as I can get a lad on it for a couple of days. But not done it before with pole to know if it's a ballache that way.
anyway I offered to do a test section and provide a written quotewhen emailing an invoice for other work done but not heard back. Not sure I will now.
