Plumber in North Philly (East Kensington)?

[Moon Molson]

After digging into the ceiling of my rental duplex to remunerate some mold, I found that the stackpipe that is supposed to vent to the outside through the roof is actually venting INTO THE CEILING. Never mind this is a new build that's barely three years old!

Anyway, I'd appreciate any recommendations for a good plumber in Philadelphia close to East Kensington/Fishtown to build this pipe out through the roof or a side wall (which is what should've been done in the first place).
