Yes. I see the plumbers (but not all) and electricians and window installers, gate and iron work and cabinet makers are almost exclusively Dominican.There are still plenty of Dominicans working in construction, especially as carpenters, plumbers, tile layers...etc.
But all of the block and concrete work, painting and landscaping seem to be Haitians near me and lately I see a some Haitian tile setters. Maybe it's the trades that are in the hot sun..
