Being a new homeowner, thought this might be a good idea to have a thread where anyone can post questions and answers to members' questions regarding home repair or improvement. So I'll start. Wife and I are doing a laminate hardwood floor in three bedrooms and the landing area at the top of our stairs. We assumed that we could have a free flowing laminate hardwood floor for the entire three rooms/landing area, but the store is telling us we MUST have T-bar transitions/seams in each doorway, and that it can NOT be free flowing due to the need for the floor to expand/contract. I understand laminate needs room to expand and contract, and surely there will be a quarter inch gap along every wall and all around the perimeter of every room for this (covered with a shoe molding), so I don't understand why the lousy three foot doorways are critical to have a T-bar for more expansion, because in either direction out from any doorway, ultimately you're going to hit a wall perimeter where there's going to be a 1/4" gap anyway, just as if it were a really large room with no doorways. I don't understand why the doorways can't be free flowing and just use the perimeter gap in either outward direction for expansion/contraction? I think it's pretty stupid to have seams between rooms and a bunch of extra plank cuts when you have the same floor throughout a given area. The guy at the store couldn't really explain it so here I am.
