It's ironic that solid hardwood flooring is once again the favored choice in wood flooring for the home. At one time, solid hardwood was the only game in town. As time went on, more variations of the classic wood floor have popped up, some better than others--engineered wood, laminate "wood" flooring, resilient tile mimicking wood, and more.

But--as the ads like to tout--nothing quite feels like real, solid wood flooring. It's sturdy, feels good under foot, and maintains value.

1. What Is Solid Hardwood Flooring? Hardly a Dumb Question.

This is not a question to be taken lightly. Engineered wood flooring--that is, flooring with a plywood-type base and faced with hardwood--can arguably be called hardwood flooring. Flooring manufacturers like to claim this, too.

Thus the emphasis on solid hardwood flooring--flooring that is hardwood from top to bottom. And the hardwood part is significant, too, as soft woods like pine are not used for daily-use flooring. Bamboo is not a solid hardwood--in fact, it's not a wood at all--yet it is sold within the same category. Finally, classic tongue-and-groove is one hallmark of solid hardwood flooring.

2. Where You Can Install Solid Hardwood Flooring

Solid. Hard. Those words give the impression that solid hardwood flooring is an indestructible material, suited for all places in the house. Let's look at various parts of the house and how they are suited for hardwood installation:
  • Basements: No. Basements, also known as below-grade locations, are a poor choice due to the high moisture content.
  • Dining, Bedroom, Living, etc.: Yes. All at-grade or above-grade locations, with the possible exception of the locations listed below, are excellent choices.
  • Kitchens: Possible. Solid hardwood can work in kitchens, but many homeowners choose to install more moisture-resistant surfaces such as tile or resilient flooring.
  • Bathrooms: Not recommended. Too much moisture.

3. Choosing Solid Hardwood Flooring Over Other Types of Flooring

Sure, engineered wood flooring, laminate, and resilient flooring may look like solid hardwood. But how do they compare on major points?
  • Solidity: Solid hardwood feels solid. Except for engineered wood floor, no other wood or wood-type flooring gives you that same feeling of solidity.
  • Structural Properties: This solidity is due to solid hardwood's structural properties, bridging minor gaps, smoothing minor bumps. Engineered wood provides this, but laminate and resilient flooring do not.
  • Resale Value: Solid hardwood is a plus that will increase the value of your home. Engineered wood's resale value is comparable.
  • Price: Good solid hardwood floor starts around $4.50 per square foot. Engineered flooring ranges around the same price, and laminate is far cheaper than either.
  • Installation: If you're considering DIY-installing your solid hardwood, you may get a better result if you hire a crew. Laminate and resilient flooring are DIY-friendly.

4. Choosing a Wood Species

Wood species refers to the type of wood--oak, maple, ipe, tigerwood, etc. Provenance, hardness and grain are two factors that will affect your choice.

Provenance: i.e., Where does the wood flooring come from? Wood flooring falls into either domestic or exotic species. Domestic species--oak, maple, beech--tend to be cheaper and have milder coloration. Exotic hardwood flooring--ipe, kempas, anything "Brazilian"--may have dramatically contrasting colors and be harder woods.

Hardness: Any wood can be soft or hard, and even so-called hardwoods can be quite soft. Heartpine and ash are soft hardwoods that may dent and scratch over time; mahogany and Brazilian walnut are two examples of hard hardwoods. The Janka hardness rating system rates the hardness of wood by firing a .444 inch steel ball into the wood and measuring depth of impact.

Grain: Close-grain wood has fibers which are packed tighter together and offer a harder surface. Maple, alder, and walnut are examples of close-grained woods. Open-grained woods are loosely packed and splinter more easily. Pine and fir are extreme (non-flooring) examples of close-grained wood. Within the flooring world, oak and ash, while still relatively hard, are more open-grained that other types.

  • Maple: Maple is a close-grained light wood with a creamy color.
  • Red Oak: Possibly the most popular solid hardwood floor species, red oak has a pink tinge and an open grain. It is relatively inexpensive.
  • Beech: Beech is one of my personal favorites, as I once installed it in my house. Beech has very dramatic, contrasting streaking and whorls.
  • White Oak: Not white, but with a coloration verging on light brown and a medium Janka hardness similar to his red oak cousin.
  • Cypress: Cypress, like beech, has a very in-your-face appearance, not for the faint of heart. Cypress will give your home a home-like, cabin-y feel.
  • Bamboo: Absolutely not a hardwood, not even a wood. But bamboo is now categorized in the solid hardwood arena, so we include it. Bamboo is a grass. Bamboo is made durable for flooring by the adhesive used to bind the materials and by use of the strand bamboo method.
  • Kempas: Kempas is a very hard flooring wood originating from Malaysia and Indonesia, ranking a high 1710 on the Janka scale.
