I own a home in northern Michigan.

The square wood porch posts sit on 1 1/2" high wood bases. The wood bases sit on the poured concrete porch surface. The snow sits against the porch posts/bases all winter. Also, I think the bases are absorbing mosture out of the concrete porch. As a result, the paint comes off the bases every year. Now, the wood bases are getting a little deteriorated.

I need help/advice on how to address and correct.
