Over the years, brick molding on masonry buildings will experience wear and tear far greater than its surrounding materials for a number of reasons. Masonry, when wet will hold water permeation and release it at a slow rate. Wood unfortunately will absorb water at a high rate if not sealed appropriately so as a result, any brick or stone units abutting unsealed wood-work will maintain this moisture saturation for long period of time. This long marriage of moisture and materials will continually saturate the wood leading to rot and decay.
