I think some of the prices that are being stated that you can earn maybe earnt now but i really cant see it staying this way, I think councils and management companys will twig onto this soon realising it will be cheaper to buy the system for a few thousand and employe there own in house cleaner to do it and save themselves a absolute bomb in the process, so take advantage now of the 100s of pounds an hour some state to get. Competition will be huge soon so if someone is happy to earn a really good wage cleaning them compared to someone who expects to earn in a day what most people earn in 2 weeks then fare play to them, I hate doing gutters, fascias and soffits so if i dont pass them on then i will price well for them but I would never rip someone off by charging 100s for a hours work.
