Bringing in out of state contractor

[Stu Basham]

Hi there, I live in Jersey City and have developed a great relationship with my plumber the past year doing my live in renovations. We enjoy working together and he's taught me a lot when he's been over to fix things. I'm about to start investing in Philly where his company doesn't have a license but is a reasonable drive. Is there any way around having to be licensed in the state for example having him do the work and have a licensed PA plumber sign off on the work or is that a total no no. Just looking for ways to keep using this guy who I trust and would like to keep giving business to. Thanks
