Columns & Trim

Enhance a home’s appearance.


Although traditionally used in exterior applications, today’s columns add a distinctive accent as interior structural supports, as part of mantels, as room dividers, in gazebos, in porticos or in trellising. Porch and lamp posts add a distinctive touch to any style home. Often used as the supporting element for porches in ranch style homes, or combined with balusters, rails, and decorative millwork, they help establish the popular Victorian style. Today, posts are used in a variety of applications including decks, gazebos, and trellises.
