As time passes, season to season your home begins to settle and cracking begins to appear along the base molding as well as the crown molding, and even where the wall meets the ceiling. The best way to handle this problem is to caulk along these opening which will first keep out any small pest wanting to get in there and cause you more problems you don’t need, and secondly give your home a nice uniform look, which is accentual before painting. Crown and Base moldings are a great way to finish off the look of a room, and also prevent scuffing from shoes and furniture protecting the walls and paint along the base of the walls.
