A damp basement is usually caused by either leaky plumbing, a crack in the foundation, poor ventilation, or possibly inadequate insulation. Moisture does not just appear in basements for no reason.
You can usually tell a leaky pipe or crack pretty easily, so in most cases, if you can't see the source of the water it is due to poor ventilation or insulation.
Something as simple as installing an exhaust fan could solve the problem with very little cost.
If the problem is
a leaky pipe or cracked foundation, then you just have to bite the bullet and pay whatever it takes to get it fixed.
Either way, this is a Bob Villa repair job, not a Martha Stewart repair job. It's going to cost more than a box of baking soda and will more than likely involve power tools.
