Came home today and I smelled gas, so I called PG&E and of course they came out to check on it. Apparently my range top has a slow leak and the gas to it is being shut off until I get it fixed. Who can I call to fix this type of problem? The PG& E guy said a plumber but that sounds wrong?? Advice, referrals, point me in the right direction please, does anyone know how I should go about getting this fixed???
