We are installing engineered wood floors in our adjoining dining room and living room. My question is, do we have to place a transition in between two rooms, or can we just install the wood floors as if it's all one big room? There's an archway between the two rooms. We tried to place a T-mold in between but it doesn't look good. Any tips would be greatly appreciated.

If it is a gluedown or nail down, you don't need the transition, A floating installation may need it depending on the size of the doorway opening. Less then 5 feet and you will need a transition in a floater as REQUIRED.

May I ask why I need a transition if the doorway is less than 5 feet? Thanks for your reply.

Because the two areas float independently. That small connection between the bigger areas will separate and come apart.

Thank you so very much for taking the time to answer my questions. Know that you have helped a single soul and made a difference in someone's life with your generosity in sharing your knowledge and wisdom regarding flooring. The LORD bless you and your endeavors.

Can I glue down the 1 transition piece if i'm installing floating floor?

Thanks

Yes, as long as you don't glob so much glue that ir also glues down the flooring at that edge.

What kind of flooring you are installing?
Is it over the concrete? did you use moisture barrier?
I wouldn't use T mold.
When I install hardwood floor I try to avoid T mold as much as I can, I change the directions of the floor when entering in the rooms.
I use T mold and End Caps only if the level of the subfloor is diffrent and I have to use some kind of treshold. MOst of the time I level the subfloor even if this means taking off the extra leyer of particle board or plywood.
The only reason to put extra unnessesary T mold would be hmmmm
making an extra triping step?
Any other opinions?
Good luck.
