Could someone advise me where to look for window cleaning ladders please? How long would they need to be? Are any safety attachments recommended for them? I'm also looking into cleaning gutters, this would take a longer ladder. I'd imagine having one set of ladders long enough to do both would mean they'd be heavier than they need to be for a regular window cleaning round? Is it possible to buy ladders where you could attach an extension on for the occasions you need them slightly longer? Last thing, what length would they need to be for gutters on a regular two storey house? Cheers!
