"Sometimes the solution really is simpler than you think...but only after you've tried everything else first, right?"
Haha, exactly. I'm currently dealing with dampness in our garage and assumed it was poor ventilation. Now I'm wondering if it's the slab too. I'll definitely try your plastic wrap trick tonight—thanks for sharing that tip!
Had a similar issue in my basement workshop a while back—thought it was ventilation too, but turned out moisture was seeping up through the slab. The plastic wrap test is great for figuring that out. If you do find moisture underneath, sealing the concrete with a good penetrating sealer can help a lot. It's pretty straightforward: clean thoroughly, let it dry completely, then apply the sealer evenly. Worked wonders for me...good luck!
That's exactly right, sealing helps a ton. I'd also suggest checking your exterior drainage situation—sometimes moisture issues start outside. Had a client whose basement stayed damp until we improved the grading around his foundation...made a noticeable difference.
