So, back in November, we finally got that annoying bedroom wall rebuilt/re-insulated. It had been an issue since we bought the place in 2003, but we we're positive it was an insulation issue, but were pretty sure.

Anyway, we had a contractor out, got a quote ($850), and went ahead and did it. When they ripped off the old drywall, they found that, as we suspected, the old insulation had mostly settled/was non-existent. After 3 days, they were finished, and the results are wonderful!

No more freezing in there during the winter!
