who will fix this?

Not looking too good, the cornice and the fascia board on Claudia's Surf City, as Dada points out. It was a smaller hole last year, but then the rain drove in and the sun shone —climate got it, if not climate change.
It's a tricky bunch of angles. I have all the requisite molding stocks, mouldering and primed under the house. I might even try it myself. Except for being afraid of heights.
Trying to find a carpenter willing to do this small and finicky a job on an island of carpenters getting ready for season will be a job in itself. Maybe duct tape.
Fortunately we have no squirrels on Block Island.
