Flooring Tile - tile up to or under door jamb

We are replacing vinyl adhesive tile with ceramic tile in an area in our home. The tile will go up to a door that has a metal door jamb. The existing vinyl tile was thin enough to fit under the jamb. The backerboard and ceramic tile will not. I cannot see how to remove the door jamb unless the entire thing is removed and replaced as it will be damaged in the removal. What is the best way? Do I tile right up to the jamb? Should we grout or caulk that space? What kind of caulk? Any help would be much appreciated.

they make undercut saws for that purpose either hand or electric:cool:

We have an undercut saw and there is no way possible that it would cut through the thickness of the metal of the jamb. Than I would have a jagged metal edge from what was left. Maybe I was not clear this is the threshold, if we undercut the metal it would compromise the whole thing, which is what we want to avoid.

I am certainly NO tile expert. I will say though that if you cant underut the door jamb then don't bother with it. You will notice a damaged door way before a quarter inch gap. All I would do is get as close to the jamb as possible and put a small bead of caulk in the gap and call it good. Don't loose sleep over it. In all of my projects I find that I am the most critical person. Nobody else would even notice the things that I wind up overstressing about :). I think as long as you put some caulk in the gap( or maybe even just grout the gap) preventing any moisture from collecting you should be all set. Again, I am no expert but like I said earlier, I would notice a dented/damaged doorjamb well before a little gap in tile. Good luck.

Thanks for the sound advice

sorry missed the metal jamb part,cut a s close as you can as suggested and fill with grout:cool:
