Good plumber

I just had my 3rd floor redone. When I cut the gas back on for the stove I smelled a faint gas odor. Call the gas company they say they cant find it so it must be in the wall. So since its on the 3rd and top floor Im guessing I will have to pull up the new tile floor and find that leak. Im in Bedstuy. does anyone have a good plumber that can resolve this situation. Thanks Ray
