I know how long 100 metres takes , its about 2 hours , I have done quite a few that length and over
Are you sure it would only take 2 hours from ladders?
I reckon, based on a calculation of my arm span being 1.75 meters (my height) that 100 meters of guttering would take 56 ladder climbs, but probably more; call it 60 climbs. (I do realise that a pole with an applicator attachment is usefull for greatly extending your reach, for scraping out gutters, but I tend to use just my hands and rubber gloves).
So, say each climb up and down of the ladder plus a ladder move would be at least one minute (maybe more if you've got to move stuff or position a Rojak ladder stopper); so that's at least an hour taken with the ladder work.
That's not counting the cleaning of the debris and filling bags, setting up or clearing away and time spent with the customer and quoting.
I reckon 150 to 200 quid. It's a dirty job, so I'd err towards the 200 mark.
Not only that, I suspect that figure would be around half the price of a 'professional gutter cleaner' from the Yellow Pages. An aquaintance of mine worked for a 'pro gutter cleaner' and I know they don't come cheap.
