The term hardwood designates wood from broad-leaved (mostly deciduous, but not necessarily, in the case of tropical trees) or angiosperm trees.

Unfinished wood is the oldest and most popular type of hardwood floor installation. A totally natural product, the variety and density of the wood provides an infinite selection of patterns and colors that can be stained and finished in a variety of color and brightness choices.

Prefinished wood flooring is a very popular installation. Most prefinished floors have a micro beveled seam between the boards, which may or may not be appropriate in all rooms. This flooring is available in a multitude of species, board widths and stain colors and finishes.

Engineered wood floors have become popular in recent years as another available option for builders and homeowners. By bonding wood and veneer together, this style of wood product is versatile enough for glue-down installation or float-in installation at or below grade. These floors are perfect for add-on projects, expansions, and areas like basements that have cement foundations or are more susceptible to moisture.
