  • Seneca's SignatureEdge Collection features a new take on hardwood stair treads edge designs.  In addition to our existing classic rounded bullnose edge, and ultramodern square edge options, we have added three new looks.  The first is an eased edge, similar to the square edge but with a slightly rounded edge for a smoother look.  Also being introduced are the chamfered edge (angled top front edge) and double chamfered edge styles (angled top and bottom front edges) for a truly unique appearance.

  • SignatureFlex
    For those special situations requiring curved moldings, Seneca Millwork offers SignatureFlex--a variety of products made from a flexible polyurethane material that can be painted or stained like wood....

  • SignatureFlex is a product line made from a weather resistant polyurethane material.  We offer quarter round, t-moldings, reducers and stair nosing in a grained or smooth finish that coordinates with our matching hardwood products.  The grained texture can be stained like wood and the smooth finish can be painted.  These products are installed just like wood, but can be purchased pre-curved for tight radius situations, or in straight pieces that offer a slight flexibility depending on the profile.
