i got a 8 meter double allu ladder for free because of a screw up with my order, the one i ordered was 9 meter triple ladder- but they sent me this one by mistake, now my triple got damaged in transit- so they gave me a refund and let me keep this one. Thats customer service ! the triple cost £120 but i got it all back and kept this £90 one.
i ocassionally take ladders.. the best thing i would think is to have a decent long one that can fold in half- you can get them on ebay so you can make it into a stepladder shape and use it to get over gates that are locked! and use it for first floor stuff.
i used a step ladder to get over a locked gate of someone whomb i accidentally cleaned who wasnt actually one of my customers i got the wrong road, and cleaned her back windows wfp- but she rang me after she got the letter in the post and said 'i cant see how you could have possibly done the back ones anyway' hmm i didnt say anything.
i think your bound to need a ladder for something anyway
one of my customers doesnt have side access to the back ! but she has a garage and says to climb over the garage with my hose over the roof to get to the back! i do this evertime now with a light alluminium ladder.
