Extending laminate flooring into another room

We recently installed laminate flooring in half of a room with the anticipation of installing rug on the other half. We now want to just extend the laminate throughout the entire area. What would be the best way to do this? We area assuming that we would have to take off the end pieces that were cut to be replaced with full pieces, but is it necessary to take the entire floor apart?

 

From your question, I'm assuming the add on is to the ends of the boards and not the edges. Too bad, the edges would have been easier. Having never had to do this I'm not sure how easy it will be. You're correct, the cut pieces will need to go if you want a seamless look. You could also put down a transition piece and continue on from there, but I wouldn't think it would look very good. You can glue the new section to the old, but that will leave a straight line across the floor that will be pretty noticeable and I'm not sure that would hold up over time and traffic without the tongue and grove. If you try to remove a board by disconnecting all three sides, leaving the rest undisturbed, it tends to get disturbed, like it or not, and boards get damaged. I'm sure it's not a popular idea, but I really think the floor will have to be disassembled enough to get to a fresh starting point and then go from there. My guess is, someone will chime in who has done this before and give you some experienced advise. It may be the same, but then again, it may not.

 

It will take less time to dismantle the floor, then it would to try and weave it in.
