Just need to sort out the ladders problem, today I had a scariest day in my last 26 years
Using ladders safely takes a bit of knowledge and common sense. I've only ever had one fall from a ladder and that was because I was hung-over, tired, dehydrated, it was a very hot day, and I took a short cut. Fortunately I was okay apart from some bruises.
Remember, some windows will not be safe to do from ladders; you don't do these windows. Just explain to the customer that it's not safe. You need a ratio of 1:4 - every four feet high, your ladders should be 1 foot out. The ground should be level. If it's not, use a ladder mat. A Rojak ladder stopper is a good bit of kit too for any awkward angles. The surface you place your ladders on should be safe (wet decking for example is lethal), and I've read posts from guys here who've fallen when they've placed their ladders on iron drainage covers, only to have them break under the weight of their body and the ladder. Accidents can and do happen.
When I first started, I did some dangerous stuff trying to clean the top pane of glass in sash windows, but I soon learnt how to do the safely.
My advice would be to phone around your local area, find a traditional window cleaner, and ask if you can be his 'helper' for a few days for free. You'll clean windows for free, for training. I did this.
And as soon as you can get a WFP. A backpack set up would cost under £500 and you can clean the 'tops only' and trad the ground floor; or WFP anything that's awkward, such as leaded or georgian windows.
And if it feels dangerous, it probably is. Take your time, don't rush, and if you're tired, take a break.
