Just had a 3 hour fight with a single plank of engineered wood
It was the last piece in a 400 square foot living room in a 1920s house, and the subfloor had a hidden dip right at the wall. Getting that final board to lock in without a visible gap took me from 4 PM to almost 7 PM with shims, a mallet, and a lot of creative language. What's your go-to trick for dealing with an uneven subfloor at the very end of a run?
Man, that last board is always the worst. For a hidden dip like that, I've had to pull the baseboard off to get more room. You can slide a long, thin shim under the board from the wall side before you try to lock it in. Sometimes you need to pre-bend the board a little by putting weight on it away from the wall. It's a huge pain, but that extra space from removing the trim can save your sanity.
Used to think pulling trim was a waste of time until a job last year broke me. Now I see exactly what @victorw95 means, that extra inch from taking off the baseboard is a total game changer. Pre-bending the board like you said is the only way to fight that spring back when the floor dips. Saves so much cussing and damaged edges.
Honestly, pulling trim feels like making more work most days. A good pry bar and some patience at the wall gets that last board in without all the extra steps. Had a job with original 100 year old trim, no way was I risking it. Just tapped in a slim wedge from the top to guide the board down over the hump.
