The Superior Hardness of Hickory Wood
Hickory enjoys a prestigious position among domestic hardwoods due to its exceptional hardness and density. According to scientific measurements, hickory is the densest commercial wood in the United States, weighing approximately 50 pounds per cubic foot when dry.
This remarkable density translates to exceptional performance metrics that outshine most other domestic hardwood options.
The wood’s hardness is objectively measured using the Janka hardness scale, which quantifies a wood species’ resistance to wear and denting by measuring the force required to embed a steel ball into the wood surface.
With an impressive rating of 1,820 pounds of force (lbf), hickory ranks as one of the hardest domestic hickory wood flooring options available in the United States. This extraordinary hardness makes it particularly resistant to dents, scratches, and general wear that typically affect softer woods.
Additionally, hickory demonstrates superior structural properties with a modulus of elasticity of 14.90 GPa, significantly higher than other popular hardwoods like maple (12.62 GPa).
This physical property indicates that hickory requires greater force to deform, making it more resistant to sagging and warping across its length.

Physical Properties and Performance Characteristics
Hickory wood possesses a unique combination of physical properties that contribute to its excellent performance as flooring material. It is exceptionally heavy, hard, and strong, while also maintaining flexibility with a coarse and straight grain structure.
This balance of strength and flexibility gives hickory superior shock resistance—a characteristic that helps prevent cracking under impact.
The wood’s natural composition makes it highly resistant to crushing forces, allowing it to withstand both shearing and straining stress.
This resilience is why hickory has historically been used for tool handles, sporting equipment, and industrial applications where strength is paramount. When applied to hickory wood flooring, these qualities translate to exceptional longevity even in high-traffic areas.
One notable characteristic of hickory is its relatively dry nature, which affects both its working properties and performance.
While this dryness allows hickory to accept stains and adhesives readily and achieve a lustrous finish, it also means the wood requires special handling during installation to prevent splitting and warping.

The Distinctive Aesthetic Appeal of Hickory
Beyond its impressive durability, hickory wood flooring offers a visually striking appearance that has gained popularity in contemporary interior design. Hickory is renowned for its intricate wood grain patterns, mineral streaks, naturally occurring knots, and dramatic colour variations within individual boards.
These natural elements contribute significantly to hickory’s rustic charm and unique visual appeal.
The wood features a pronounced contrast between heartwood and sapwood, creating a dynamic visual effect that ranges from creamy white to rich brown tones, often with reddish highlights.
This natural colour variation allows hickory flooring to complement diverse interior design styles, from rustic farmhouses to modern contemporary.
Hickory’s distinctive character—featuring streaks, knots, and swirly, busy grain patterns—was once considered less desirable for furniture and cabinetry.
However, modern design trends have embraced these natural characteristics, elevating hickory’s status in interior applications. Wider planks are particularly effective for showcasing hickory’s distinctive patterns and character marks, creating floors with unmistakable personality and visual interest.

| Red Hickory | Pink to reddish-brown tones | Moderately pronounced | Warm undertones, medium character marks |
| Calico Hickory | Dramatic light/dark mix | Highly varied | Maximum contrast, distinctive visual impact |
Installation Considerations and Best Practices
Installing hickory wood flooring requires careful attention to several key factors to ensure optimal performance and longevity.
Due to Hickory’s unique physical properties, proper installation techniques are essential to prevent future problems.
Hickory is particularly sensitive to moisture content changes, similar to oak. Flatsawn hickory lumber pieces will change size by approximately 1% for every 3% change in moisture content (equivalent to a 20% relative humidity change).
This sensitivity makes proper acclimation critical before installation. Industry professionals emphasize that hickory requires “a significant period for acclimatization before sanding” to allow the wood to adjust to the home’s environment.
The National Wood Flooring Association (NWFA) recommends maintaining a 3/4″ expansion space around all edges when installing hickory wood flooring. This expansion gap is typically measured from fixed, hard surfaces like framing elements rather than drywall surfaces.
This allowance is necessary because hickory is “known to be one of the hardwoods that are least stable in terms of dimensions”, contracting in winter and expanding in summer.
Proper subfloor preparation, moisture testing, and the use of appropriate moisture barriers are essential for successful hickory floor installation. For installations over concrete slabs, moisture testing of the concrete is critical, as is the use of an effective moisture barrier.
Similarly, for installations over crawl spaces, assessing and controlling moisture levels beneath the home is crucial for preventing future issues.
Table 4: Critical Installation Requirements for Hickory Flooring
| Installation Factor | Requirement | Reason |
| Acclimation Period | 7–14 days minimum | Allows wood to stabilize to home’s environment |
| Expansion Gap | 3/4″ from fixed structures | Accommodates seasonal dimensional changes |
| Subfloor Moisture | Less than 12% for wood subfloors | Prevents excess moisture transfer to flooring |
| Room Conditions | 35–55% relative humidity | Maintains dimensional stability |
| Fastener Schedule | 8″ spacing, 2″ from board ends | Secures boards while allowing for movement |
| Installation Direction | Perpendicular to floor joists | Maximizes structural stability |
Maintenance and Longevity Factors
Hickory flooring’s maintenance requirements are comparable to other hardwood options, though its exceptional hardness provides advantages for long-term care.
The wood’s dense structure resists wear, making it particularly suitable for high-traffic areas and households with children and pets.
While hickory’s hardness makes it resistant to mechanical damage, it remains sensitive to moisture. Maintaining consistent humidity levels (35-55%) in the home is essential for preserving the floor’s dimensional stability and preventing gaps or crowning issues.
After installation and several years of proper stabilization, hickory floors can be refinished successfully, assuming appropriate moisture levels are maintained.
When properly maintained, hickory wood flooring can last for generations. The wood’s natural durability combined with its ability to be refinished multiple times contributes to its exceptional longevity.
Furniture makers and flooring professionals report excellent performance from hickory finishes, with hard wax oil finishes like Rubio performing well even after years of use.
For cleaning and maintenance, regular sweeping and occasional damp-mopping with wood-appropriate cleaners are sufficient. Due to hickory’s hardness, it may be more challenging to sand during refinishing, requiring sharp tools and fresh sandpaper to achieve premium surfaces.
