Quality Wood: Shop Like A Pro! (7 Inspector Secrets!)

Not all wood is created equal—understanding the nuances of quality wood can mean the difference between a stunning investment and a regrettable purchase that ages poorly.

I’m a flooring contractor, and I’ve seen it all when it comes to wood. Beautiful, durable floors that last generations, and… well, let’s just say some real disasters.

Choosing the right wood is crucial, whether you’re installing new floors, building custom furniture, or remodeling your kitchen cabinets.

The wrong choice can lead to warping, cracking, fading, and a whole lot of frustration.

It can also be a significant financial hit. Trust me, replacing an entire hardwood floor because you chose the wrong species or grade is not a fun experience.

That’s why I’m sharing seven insider secrets that professional inspectors use to evaluate and select quality wood.

These are the tips and tricks I’ve learned over years in the trade, and they’ll help you shop like a pro, avoid costly mistakes, and ensure you get the best possible wood for your project.

Ready to dive in? Let’s get started!

Section 1: The Basics of Wood Quality

So, what exactly makes wood “quality”? It’s not just about looks, although appearance is definitely a factor.

We need to consider these factors like species, grade, finish, and sustainability.

These factors influence the wood’s durability, appearance, and overall performance.

Think of it like this: you wouldn’t choose a flimsy cardboard box to store your valuable tools, right? Same goes for wood.

Species: Different wood species have different densities, grain patterns, and natural resistance to moisture and insects.

Grade: The grade of the wood refers to its appearance and the number of defects it contains.

Higher grades have fewer knots and imperfections, while lower grades are more rustic and may require more preparation.

Finish: The finish protects the wood from moisture, scratches, and UV damage. It also enhances the wood’s natural beauty.

Sustainability: Choosing sustainably sourced wood helps protect our forests and ensures that future generations can enjoy the benefits of this valuable resource.

For example, a high-quality oak floor, properly finished and maintained, can easily last 100 years or more.

On the other hand, a poorly chosen wood, like a soft wood in a high-traffic area, might show wear and tear within just a few years.

Section 2: Understanding Wood Species

Let’s talk about wood species.

It’s like choosing the right tool for the job. Each species has unique properties that make it suitable for different applications.

Here are some of the most common wood species used in construction and furniture making:

• Oak: Oak is a classic choice for flooring and furniture. It’s strong, durable, and has a beautiful grain pattern. There are two main types of oak: red oak and white oak.

  White oak is more water-resistant than red oak, making it a better choice for outdoor applications. * Maple: Maple is a hard, dense wood with a fine grain. It’s often used for flooring, cabinets, and furniture. Maple is known for its light color and smooth surface. * Cherry: Cherry is a beautiful hardwood with a rich, reddish-brown color. It’s often used for high-end furniture and cabinetry. Cherry darkens over time, giving it a warm, aged look. * Walnut: Walnut is a luxurious hardwood with a dark, chocolate-brown color. It’s often used for furniture, cabinetry, and decorative accents. Walnut is known for its distinctive grain pattern. * Pine: Pine is a softwood that’s commonly used for framing, trim, and furniture. It’s a more affordable option than hardwoods, but it’s also softer and more prone to dents and scratches.

  Fun Fact: Did you know that the Janka hardness scale measures the resistance of wood to denting and wear?

  Red oak has a Janka hardness rating of 1290, while Brazilian walnut (Ipe) boasts an impressive 3680!

  This means Ipe is nearly three times harder than red oak. (Source: Wood Database)

So, how do you tell the difference between these species when you’re shopping?

• Look at the grain pattern: Each species has a unique grain pattern. Oak has a prominent, open grain, while maple has a finer, more subtle grain.
• Consider the color: Cherry is reddish-brown, walnut is chocolate-brown, and maple is light-colored.
• Check the hardness: If possible, try scratching the wood with your fingernail. Hardwoods like oak and maple will be more resistant to scratching than softwoods like pine.

Section 3: The Importance of Grading

Wood grading is like getting a report card on your lumber. It tells you about the appearance and quality of the wood, based on the number and size of defects.

The grading system varies depending on the species and the organization that sets the standards.

In the United States, the National Hardwood Lumber Association (NHLA) is the primary source for hardwood grading rules.

For softwood lumber, different grading rules apply, often set by organizations like the Western Wood Products Association (WWPA).

Here’s a simplified overview of hardwood grades:

• FAS (Firsts and Seconds): This is the highest grade of hardwood lumber. It’s clear, with long, wide boards that are mostly free of defects. FAS grade is ideal for high-end furniture and cabinetry.
• Selects: This grade is similar to FAS, but it allows for slightly smaller board sizes. It’s still a high-quality grade with few defects.
• Common Grades (Number 1 Common, Number 2 Common, etc.): These grades have more defects than FAS and Selects. They’re often used for applications where appearance is less critical, such as flooring, cabinet parts, and furniture frames.

Softwood lumber grades often use terms like “Select Structural,” “Construction,” and “Standard.”

“Select Structural” is a high grade with few defects, suitable for structural applications where strength is important.

“Construction” and “Standard” grades have more defects and are typically used for general construction purposes.

So, how do grades affect appearance and performance?

• Appearance: Higher grades have fewer knots, splits, and other imperfections, resulting in a cleaner, more uniform look.
• Performance: Higher grades are typically stronger and more stable than lower grades, making them a better choice for applications where structural integrity is important.

What should you look for in high-grade wood?

• Minimal defects: Look for boards that are free of knots, splits, checks, and other imperfections.
• Straight grain: Wood with a straight grain is more stable and less likely to warp or twist.
• Consistent color: Look for boards that have a consistent color throughout.

How can you identify different grades in person?

• Ask the seller: Don’t be afraid to ask the lumberyard or retailer about the grade of the wood.
• Look for grade stamps: Some lumber is stamped with the grade. Look for these stamps on the ends or faces of the boards.
• Visually inspect the wood: Carefully examine the wood for defects. Compare different boards to see how they vary in appearance.

Section 4: Inspecting for Defects

Alright, let’s get down to the nitty-gritty of inspecting wood for defects.

This is where you really start to think like a pro.

Common defects can significantly impact the wood’s strength, stability, and appearance.

Here are some of the most common defects to watch out for:

• Knots: Knots are caused by branches that were embedded in the tree. They can weaken the wood and affect its appearance.
• Splits: Splits are cracks that run along the grain of the wood. They can be caused by drying or stress.
• Checks: Checks are small cracks that run across the grain of the wood. They’re often caused by uneven drying.
• Warping: Warping is a distortion in the shape of the wood. It can be caused by uneven drying or improper storage.
• Cup: A cup is a type of warp where the edges of the board are higher than the center.
• Bow: A bow is a type of warp where the board is curved along its length.
• Twist: A twist is a type of warp where the corners of the board are not in the same plane.
• Shake: Shake is a separation along the grain of the wood, often caused by wind or frost.
• Pitch pockets: Pitch pockets are small cavities in the wood that contain resin. They’re more common in softwoods like pine.
• Insect damage: Look for signs of insect damage, such as small holes or tunnels in the wood.

Here’s a step-by-step guide on how to inspect wood for these defects:

1. Start with a visual inspection: Look at the wood from all angles. Check for knots, splits, checks, warping, and other visible defects.
2. Feel the surface: Run your hand over the surface of the wood. Check for rough spots, splinters, or unevenness.
3. Check for squareness: Use a square to check if the board is square. This is especially important for wood that will be used for framing or cabinetry.
4. Look for straightness: Sight down the edge of the board to check if it’s straight. Look for any bows or twists.
5. Check for moisture content: If possible, use a moisture meter to check the moisture content of the wood. The ideal moisture content for most woodworking applications is between 6% and 8%.

What should you avoid and how to spot red flags?

• Avoid wood with large, loose knots: These knots can weaken the wood and may fall out over time.
• Avoid wood with splits or checks: These defects can worsen over time and cause the wood to crack.
• Avoid wood that is warped or twisted: Warped wood can be difficult to work with and may not be suitable for certain applications.
• Be wary of wood that is excessively wet or dry: Wood that is too wet can warp or rot, while wood that is too dry can become brittle and crack.
• If the price seems too good to be true, it probably is: Low-quality wood is often sold at a discount.

Section 5: The Finishing Touch

The finish is like the icing on the cake.

It not only enhances the wood’s appearance but also protects it from moisture, scratches, and UV damage.

Different types of finishes have different properties and are suitable for different applications.

Here are some of the most common types of finishes:

• Polyurethane: Polyurethane is a durable, water-resistant finish that’s often used for flooring, furniture, and cabinets. It’s available in both oil-based and water-based formulas. Oil-based polyurethane is more durable but has a stronger odor and takes longer to dry. Water-based polyurethane is more environmentally friendly and dries faster, but it’s not as durable.
• Varnish: Varnish is a clear, glossy finish that’s similar to polyurethane. It’s often used for furniture, boats, and other outdoor applications.
• Lacquer: Lacquer is a fast-drying finish that’s often used for furniture and cabinetry. It’s available in a variety of sheens, from matte to high-gloss.
• Oil Finishes: Oil finishes, such as linseed oil and tung oil, penetrate the wood and provide a natural, matte look. They’re often used for furniture and woodturning projects.
• Wax Finishes: Wax finishes, such as beeswax and carnauba wax, provide a soft, lustrous sheen. They’re often used over oil finishes to add extra protection.

How does the finish affect durability and appearance?

• Durability: Some finishes, like polyurethane and varnish, are more durable than others, like oil and wax. Durable finishes are better able to withstand scratches, stains, and moisture.
• Appearance: The finish can enhance the wood’s natural beauty by bringing out the grain and color. Different finishes have different sheens, from matte to high-gloss.

How can you evaluate the quality of finishes applied to wood products?

• Look for an even, smooth surface: The finish should be applied evenly, without runs, drips, or brush marks.
• Check for good adhesion: The finish should adhere well to the wood, without peeling or flaking.
• Test for scratch resistance: Try scratching the finish with your fingernail. A high-quality finish should be resistant to scratching.
• Check for water resistance: Put a drop of water on the finish and let it sit for a few minutes. A high-quality finish should repel the water and prevent it from soaking into the wood.
• Consider the application: The number of coats applied also impacts the quality of the finish. Multiple thin coats are generally better than one thick coat. This approach helps ensure even coverage and proper curing.

Section 6: Sustainability and Sourcing

Sustainability is no longer just a buzzword; it’s a critical consideration when choosing wood.

Our forests are a valuable resource, and it’s important to ensure that they’re managed responsibly.

Choosing sustainably sourced wood helps protect our forests, supports local communities, and reduces our environmental impact.

What does “sustainably sourced” mean?

It means that the wood comes from forests that are managed in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs.

This includes practices such as:

• Selective harvesting: Harvesting only mature trees and leaving younger trees to grow.
• Reforestation: Planting new trees to replace those that are harvested.
• Protecting biodiversity: Preserving the natural habitat of plants and animals.
• Using environmentally friendly logging practices: Minimizing soil erosion and water pollution.

Certifications and labels indicate responsibly sourced wood.

The most well-known certification is the Forest Stewardship Council (FSC) certification.

FSC-certified wood comes from forests that are managed according to strict environmental and social standards.

Other certifications include the Sustainable Forestry Initiative (SFI) and the Programme for the Endorsement of Forest Certification (PEFC).

When shopping for wood, ask questions about the sourcing.

Don’t be afraid to ask the lumberyard or retailer where the wood comes from and whether it’s certified.

A reputable supplier should be able to provide you with information about the wood’s origin and sustainability credentials.

You can also look for labels and certifications on the wood itself.

For example, look for the FSC logo or the SFI label.

By choosing sustainably sourced wood, you can help protect our forests and ensure that future generations can enjoy the benefits of this valuable resource.

Section 7: Tools of the Trade

Now, let’s talk about the tools of the trade.

Professional inspectors use a variety of tools and techniques to evaluate wood quality.

While you don’t need to be a professional inspector to shop for quality wood, having a few basic tools can help you make informed decisions.

Here are some essential tools that buyers can use while shopping for wood:

• Moisture Meter: A moisture meter measures the moisture content of the wood. This is important because wood that is too wet or too dry can warp, crack, or rot.

  The ideal moisture content for most woodworking applications is between 6% and 8%. * Calipers: Calipers are used to measure the thickness of the wood. This is important for ensuring that the wood is the correct size for your project. * Straightedge: A straightedge is used to check if the board is straight. This is important for ensuring that the wood will not warp or twist. * Square: A square is used to check if the board is square. This is important for ensuring that the wood will fit together properly. * Magnifying Glass: A magnifying glass can be used to inspect the wood for small defects, such as checks or insect damage. * Measuring Tape: A measuring tape is essential for measuring the length and width of the wood.

Let’s talk about how these tools can help you make informed decisions.

• Moisture Meter: By measuring the moisture content of the wood, you can avoid buying wood that is too wet or too dry.
• Calipers: By measuring the thickness of the wood, you can ensure that it’s the correct size for your project.
• Straightedge: By checking if the board is straight, you can avoid buying wood that is warped or twisted.
