What Trade fixes downspouts?

I need two front of brownstone downspouts replaced. I did them with 3″ PVC pipe 20 years ago, but one cracked, and the other is separated from the gutter flange? up at the cornice.

It is 4 stories, a little too high for me on a ladder. One building has a fire escape on the front, complicating access. there also are trees, whic could make a lift trickier.

My question, who does this kind of work? Roofers? Masons? I have copper gutters and downspouts on the back, but should we be afraid they’d be stolen in the front?

Does anyone out there know who does this, or recommendations?

Thanks,

Bruce
