Hardwood Flooring Guide

Before choosing what type of hardwood you want for your house, you must know what subfloor you have and the moisture level.

There are three primary subfloors:

  • Basement or concrete below ground level

  • Concrete at ground level

  • Plywood subfloor at or above ground level

There are four types of hardwood floors:

  • 3/4-inch Solid

  • 5/16-inch Solid

  • Engineered

  • Locking


3/4-inch Solid

  • 3/4-inch-thick solid piece of hardwood floor
  • can only install them over a plywood subfloor at or above ground level

5/16-inch Solid

  • a thinner version of the 3/4-inch hardwood floor
  • you can't install it in the basement or on concrete below ground level
  • thin enough to glue down to concrete at ground level or install over plywood at or above ground level

Engineered Hardwood

  • designed for installation over concrete and to help mitigate potential moisture issues.
  • you can install engineered anywhere in the home, including the basement. 
  • more environmentally friendly and less expensive than solid floors

Locking Hardwood

  • A locking, or floating, floor is an engineered floor, but with the added advantage of a locking tongue-and-groove system 
  • It's the perfect do-it-yourself flooring solution because nails, staples, and glue are not required.
