     Before you commit to installing a hardwood floor, you'll want to learn about the various wood flooring choices available, the characteristics of various species of woods, and the benefits and limitations of each one. There are also specific considerations to address before you have a hardwood floor installed. To learn about hardwood flooring and determine if it's the right choice for you, Custom Interiors will do a full evaluation of the room(s) that your are considering flooring.

      Solid wood flooring is made from one continuous piece of wood. Most is 3/4 inch thick. When you look crosswise at a piece of solid flooring, you may see growth rings or striations, but there are no layers or ply. Wood strips are anywhere from 1-1/2 inches to about 2-1/4 inches wide. Planks are wider than 2-1/4 inches. Most strip and plank flooring is milled with tongue-and-groove edges so boards will fit together, but some planks are flat-edged for a more rustic look.

      kitchen floors 2The hardest species are hickory, pecan, hard maple, and white oak. Next on the list: white ash, beech, red oak, yellow birch, green ash, and black walnut. Cherry and mahogany are softer, but still make gorgeous and durable floors. Pine is a softwood, so it may dent and ding, but for many homeowners, that adds to the floor's charm. And, like hardwoods, pine should last the lifetime of your home. Southern yellow pine is the hardest pine and is recommended for higher-traffic areas. Heart pine, from the center section of old-growth Southern longleaf yellow pine, is difficult to come by and expensive, but some experts say heart pine rivals red oak in hardness. Pine flooring is often sold in widths from 4 to 16 inches to simulate what was used in Colonial-era homes.


floor grading

     The grade of flooring is the primary determinant of how the floor will look once it is installed, sanded, and finished. Stains can be used to alter color but wood characters and other marks that determine grade are likely to remain after finishing.

    Unfinished certified flooring is categorized into four grades: Clear, Select, No. 1 Common and No. 2 Common, any of which will result in a serviceable floor.

No. 1 Common
No. 2 Common
1 2 3 4


    The primary differentiator between the grades is the degree to which natural characteristics, such as knots and mineral streaks, or manufacturing marks, such as sticker stain, are allowed. The prominence and frequency of these characters increases from Clear to No. 2 Common.

    For example, Clear is mostly uniform in appearance, has a limited number of character marks, and is mostly heartwood. “Select” also has a uniform appearance, but this grade contains more of the natural characters such as knots and all natural color variations associated with heartwood and sapwood. The common grades will contain even more natural characters, as well as manufacturing marks.
