We charge around 25 to 30 per side,infact we got two on tomorrow.
I find the hourly rate drops down on add ons, but we advertise doing them, ie
Conny roofs, facia soffit gutter wash, solar panels and Gutter clearence.
Money is money at the end of the day,and these jobs top up the window cleaning turnover nicely
We do have a gutter vac (diy) and i normally use the ladder and the gutter vac.
My Mrs foots the laddder, i scoop the muck into a pile, then with gooseneck of gutter vac in hand i hoover up the worst of it.
On a lot of jobs i then get back up the ladder,and jet wash all the small debris that that vac has left,this takes only a min or two and leaves the gutters near spotless.
Book all add on jobs in for Fridays, as 90% of the time our normal window cleaning rounds are finished by Fridays
