I know that in general, trim should be installed first, followed by tack strips and then carpet. And typically I see something like having the trim be 3/8" to 1/2" off the floor and the tack strip being 3/8" from the trim (this is for home carpet).
However, as I am replacing carpet and trim, I am reusing the existing tack strips that are already installed and was planning on installing the new trim next and then carpet after that. Is this the right order in this case? Or should I just install the trim afterwards now? if I do it first should I still stick to the 1/2" off the ground rule?
