Rugs, Carpets and Carpeting - Transition from berber carpet to tile in basement....

Hello,

I am having tile and berber carpet installed in the basement. I got a call from the installer at Lowes and he was saying about having a transition (oak?) that joins the tile in the foyer and around the bar area to the carpet. I talked to a few people that said that is not a good idea. They have their carpet 'tucked' under the tile.. They said they have their tack strips spaced a few from the tile and just tucked under. Is this the best way? I don't want some oak or anything that is there and have someone trip over, etc? Just wanted to know why the installer (Says he has over 30 years experience) from Lowes state that is the best way to go (Add a transition)?

Two things i've learned from installers when they recommend a way to do something that seems odd or unecessary: (1)They were taught to do it that way by whoever trained them and (2)they have never learned another way to do it. Either way he's unlikely to do it as well as someone who knows how to properly tuck to tile. If this guy doesn't want to do that way, ask for someone else. Make sure they use a sealer in the gully to help eliminate any fraying at the tile.
