last week i picked up a house, they asked for a price, i have enough work so priced it at fairly silly money
they ummm'ed and arrrrr'ed a little and said "ok"
the windows were real bad, the old lady had died and the house had been empty for 6 years (dont know why)
so i thought about getting my ladder out, but thought again and i just connected the hose upto the outside tap, really cleaned the frames ( i dont normally do the frames, shock horror, but i didnt when i did them normally, so why now, its not that hard to not get any water on the top frame) and windows, really flooded them with normal tap water
then i went over the glass with Pure water
the job came up fairly well, the customer mentioned 1 run, BUT i had explained it might take a clean or 2 to come up real good
