As an example I was asked to give a quote for 3 large blocks of flats 3 storey jobby.
After the meet & great bit was over I wizzing around with me gopro on a pole firstly mainly for my own benifit to see exactly what I was up against. I then showed the customer the vids so he could see for himself how bad they were.
As we got chatting I found out who was the window cleaning company that does the windows bi monthly and price also regarding the price for the gutter clearing he was going to let me know too so I had something to go on as you do .
It turns out the firm does all the windows by trad and clears the guttering too by hand. However he was concered and other residents noticed this that they have to put the ladder againg the wall of the building and lean far back, reaching up into the gutters so to try and grab what they can out of it.
I think the final straw for that firm was when the chap looked at the vids and he mentioned it don't look like the gutters have ever been cleared properly. I agreed and said no it don't look that way does it.
I did not even mention the cost to do the job but he still wanted me not only to look after the gutter mainteance side of things but also take over doing the windows too as you guessed it they use ladders and don't clean the frames.
I'm just saying you can't do every job by ladders and one decent contract like that would pay for guttervac kit many times over...
As they say right tools for the job and all that
