I'm installing 1/2" engineered Brazilian Cherry in my house (glue down over concrete slab) and I have some transitions to tile that will require I resize my 3.5" baseboards to match. I really prefer baseboards sitting directly on top of the wood versus quarter round or base shoe molding, especially on the smaller 3.5" baseboards. Also, I'm not even sure a base shoe mold would work since my baseboards artistically get smaller as you move up. In other words, I think there would be a noticeable gap between the baseboard and the top of the shoe molding or quarter round if it were installed. What I'm trying to determine is whether I'm better off pulling the baseboards off, ripping them so that they match when butted up to the tile baseboards, and then reinstalling and caulking OR can I actually use something like a door jamb saw and run it along the bottom of the baseboards at a height sufficient enough for the installer to slide the wood w/glue under the baseboards (of course leaving an expansion gap). If the latter option could work, it would save a lot of time instead of removing the baseboards and then reinstalling (also kind of scribes the baseboard to the floor since it would follow the slab contour). Final step would be to caulk in any areas that need it. Thoughts?
