Exterior Product Range


Our selection of exterior trims and other architectural features will convert your home's appearance into something very special.

Flat Trims and Deco Trims easily install around windows and doorways, adding architectural interest, style and a more finished look and Sills are decorative trims that fit under the window.

Arches accentuate and add style to any doorway or window and Keystones are the central stones that enhance the appearance of arches.

Columns, or pillars, are normally applied to the front of a home or structure under a roof or porch.

Quoins, the L-shaped pieces of trim positioned on the exterior corners, flatter the shape of the structure and Quatrefoils are geo-metrically shaped pieces of trim that add style and symmetry to the exterior.

Exterior Product Range


Shutters give an accent to your windows and Faux Vents look like slatted vents and add balance and proportion to a home or structure.

Cornices are installed along the seam of where a wall and roof or ceiling of a porch meet, making it look more finished. Corbels & Brackets are like shelf brackets and are installed under the overhang of a roof.

Post Caps top off an existing post, giving it a more decorative shape and an overall finished look.
