I plan on laying vinyl planking that will transition into carpet. This is in the basement and not a highly trafficked area. This is on a concrete slab. I also have never messed with carpet so I am unsure about renting a kicker to stretch the carpet back. What is my best transition option? Can I avoid messing with the carpet by creating a transition that would overlay the current metal one? Can I lay the vinyl planks with flush with the metal transition and just allow the expansion gap on the opposite wall, which is 7 feet away? There is a 1/4" height difference as well.
