I know everyone will say to just get a bigger ladder, but it would be easier (and cheaper) if I could just find a way to apply any kind of sealant (foam will do) into a 3-inch wide by about 1-1/2 inches deep hole that the birds keep making in the wood board just below the tile roof above the balcony.
The problem is the balcony and the overhang conspire to negate the use of anything but a forty foot ladder (which I don't own, as mine is only 32 feet which is far too short) or a scaffold. Due to the overhang, even a step ladder (which I do own) won't work. Anyway, I'm not asking about a ladder.
All I want to do is stand on the balcony and apply the sealant into the 3 inch wide holes the birds are making and yes I know I should replace the wood but that has the same problem of the 40-foot ladder and I want to keep costs to a minimum.
Do they sell a ten foot long "wand" that can apply some kind of sealant that will seal up a hole that the birds keep making?
