Need completion advice, the sub that was a rock star who did my tile , coping and now working on my 1300 sq ft sandblasted marble pavers deck went MIA on the PB. There is work to be done on my very expensive deck: mastic between the coping and deck, more sand in paver lines, smooth of some of the cuts around the curves, cut of an overhang of where the pavers over extended the deck etc The PB wants to do the stonescapes plaster/ fill and then have them fix all the deck stuff with another of their Sub crews. My gut is no finish the deck first , any downside to doing what the PB suggests?
