I'm definitely NOT a pro, and I hope someone with actual skills helps you out, but this is what I'd do. :)

1. If I'm reading it right, you might be able to get an oak threshold from Home Depot or other store in the flooring department--there are more sizes available in actual wood than in laminate. I think it should look okay if the color isn't far off (and it looks like the laminate is a nice standard medium oak color).

2. Possibly wood filler with lots of patience and many thin layers? Or let it be.

3. Paintable caulk

4. I think I'd ignore it unless it was really visible.

5. I think woodfiller instead of caulk in the seams and nailholes. Not a lot of sanding should be needed.

So, remodel pros, did I get any right?

1. Door threshold: Is that subfloor exposed that's lower than the laminate or is the subfloor the same height as the laminate? If it's lower subfloor, I'd rip down a piece of laminate to fill it in. I'd also put a piece of quarter round/shoe molding against the door to cover the floor/door gap, and caulk top and bottom.

2. Broken trim: wood putty. Let it dry, sand it down to shape, then paint it. Kind of tedious, but it'll do the trick.

3. Countertop gap: Caulk in the closest color you can get to the counter (dark gray).

4. Is that the veneer peeling or the underlying wood cracking? Do you have paint that matches it? Might be a candidate for sand/putty/sand/paint.

5. Trim gaps: That's why God invented caulk. :-)

Thanks for the responses. Weedy, I think it is the same height as the subfloor, so a thin strip of laminate would work there. Should I put a transition piece between the two laminates?

I think the veneer is peeling on the cabinets, not the underlying wood. And yes, I have paint that either will match it or be close (I may have to put a fresh coat over all the cabinets anyway).

If you've got matching laminate you don't need to do a transition piece. They should lock together and be level.
