Clean bathroom vent duct and replace cap from outside?
My house has a bathroom vent fan that vents through a side wall. The hooded vent cap doesn't close very well, and birds have gotten in and made a nest.
Is there any way to clean out the vent duct and put on a better cap without cutting open the ceiling of the bathroom? I'd like to just remove the cap, pull out the nest with some tongs (the duct is only 4 feet long), and attach a new louvered cap, all from the outside of the house. I think it's a flexible aluminum duct.
One repair guy has told me, without really looking at the ductwork, that this is never a possibility since there's usually no slack in the ductwork. I'd think that pulling the cap out an inch or two would work. Would this be enough to replace the cap?
Would blowing the nest out from the inside with a leaf blower work?
