Ladder question

I have a quick question, no this isn’t about using ladders for spraying sides lol. Down here on the coast of Mississippi there are a lot of houses that have balconies. I just wanted to know do you guys use just regular extension ladders, or do they make special ladders that won’t leave marks?

Cut an X in two tennis balls and stick them over the ends of rhe bullhorns.

I have 2 thick rubber hose I have on my ladder ends… I also have the big U brackets that go on my end so it will be steady… You can also lean back quick to scoot it over to wash were it was.
