They glued the transition strip to both sides of the floor which contributed to the failure. They also didn’t install the metal U channel to the subfloor in the gap between the floors of the two rooms for the floors to float freely.

The caulk is probably a white acrylic latex but you don’t want that. It acts like a glue a prevents the floor from floating.

Here’s a link to a product that best shows the metal U channel you’re missing.

Okay so there is the metal u channel and the threshold is 2 separate pieces that are now stuck together.

Is there a way to buy a new threshold that has the same color as my current floor or should I just try to stick the glued together threshold into the uchannel?

It’s not stuck together. You have no metal at all and that’s why it was glued in place.

Technically you have a reducer moulding but the person who installed it did not do it correctly.

The metal u channel acts like a clamp to hold onto the center wood channel on the bottom of the transition strip/threshold/reducer moulding.

Moving forward, I wouldn’t worry about buying a new moulding. If you did install the U channel you would probably need to cut the floor to have the proper gap. I recommend just cleaning off the glue and then gluing it back in on just the taller floor side. While not perfect, it is good enough and will be better than you had before.

Thanks you so much. I’ll look for an acrylic glue.

You’re welcome. I like Liquid Nails construction adhesive. Just don’t use a “Gorilla Glue” type glue for this.
