How to Choose the Best Cedar Wood for Your Project: A Complete Buying Guide

When learning how to choose cedar wood for outdoor construction or interior finishes, opt for Western Red Cedar if you need natural rot resistance, dimensional stability, and a warm, aromatic finish 1. This species is among the most widely recommended for decking, siding, and furniture due to its balance of beauty and performance. Key factors like grain tightness, moisture content, and sourcing region significantly affect longevity and appearance. Always inspect for minimal knots and avoid boards with visible warping or excessive sapwood, which degrades faster 2. For those seeking long-lasting, low-maintenance material that ages gracefully to a silvery gray, properly graded cedar offers excellent value despite a higher upfront cost.

About Cedar Wood

Cedar wood refers to several coniferous tree species known for their aromatic scent, natural oils, and resistance to decay. The term 'cedar' is often used broadly, but true cedar species belong primarily to the genus Cedrus, native to mountainous regions of the Mediterranean and Himalayas 3. However, in North America, the wood commonly labeled as 'cedar' typically comes from trees in the cypress family (Cupressaceae), such as Thuja plicata (Western Red Cedar) and Juniperus virginiana (Eastern Red Cedar) 4.

These woods are prized for applications where durability and insect resistance are essential. Common uses include exterior siding, fencing, decking, outdoor furniture, closet linings, and storage chests. Their natural oils repel moths and other pests, making them ideal for protecting woolens and fabrics 5. Additionally, cedar’s lightweight nature and ease of machining make it accessible for DIYers and professional builders alike.

Why Cedar Wood Is Gaining Popularity

In recent years, interest in sustainable building materials has driven increased demand for cedar wood. Consumers are prioritizing naturally durable options that reduce reliance on chemically treated lumber, especially for garden structures, children's playsets, and indoor storage 6. Cedar requires no toxic preservatives, yet can last 15–20 years in outdoor settings when properly installed 7.

Another factor contributing to its rise is aesthetic appeal. Unlike pressure-treated pine, which starts green and fades unevenly, cedar weathers uniformly to a soft silver-gray patina unless sealed. Its rich color and straight grain also enhance curb appeal in modern farmhouse and rustic designs. Moreover, rising concerns about formaldehyde emissions in engineered wood products have led homeowners to favor solid, non-composite alternatives like cedar for closets and panelling.

Types and Variants

Not all cedar is created equal. Understanding the differences between common types helps ensure you select the right one for your project.

Western Red Cedar (Thuja plicata)

Grown along the Pacific Northwest coast, this is the most popular choice for exterior applications. It has a pinkish-brown heartwood, fine texture, and excellent workability.

Pros: High natural durability (rated up to 20 years outdoors untreated), low shrinkage, light weight, superior insulation properties 8.
Cons: More expensive than other cedars; availability varies by region.

Eastern Red Cedar (Juniperus virginiana)

Found across eastern North America, this species is denser and more aromatic.

Pros: Strong moth-repellent qualities, vibrant reddish hue, often used for lining drawers and closets 9.
Cons: Prone to checking (small surface cracks); less suitable for large structural pieces.

White Cedar (Thuja occidentalis)

Commonly used in boatbuilding and fencing due to its resilience in wet conditions.

Pros: Exceptional resistance to moisture and decay; stable even in fluctuating humidity.
Cons: Limited availability outside the Great Lakes and northeastern U.S.

Aromatic Cedar (often synonymous with Eastern Red Cedar)

This term describes any strongly scented cedar, usually marketed for pest-resistant storage solutions.

Pros: Long-lasting fragrance, effective against clothes moths.
Cons: May cause allergic reactions in sensitive individuals 10.

Key Features and Specifications to Evaluate

To determine what to look for in cedar wood, assess these five core attributes:

Grade: Lumber is graded based on appearance and structural quality. Clear Grade has no knots and is best for visible areas. Select & Better allows small, tight knots. Avoid Construction Grade for decorative use 11.
Moisture Content: Ideally below 15% for indoor use and 19% for exterior installations. Kiln-dried or air-dried options perform better than green (fresh-cut) wood 12.
Density and Grain Tightness: Tight annual rings indicate slower growth and greater strength. Look for at least 6–8 growth rings per inch.
Sourcing Region: Pacific Northwest-sourced Western Red Cedar tends to be more durable than southern-grown substitutes.
Treatment Status: Most cedar is sold untreated. Verify that no additional chemicals were applied, especially for indoor projects.

Pros and Cons

Advantages:

Natural resistance to rot, insects, and mildew without chemical treatment 7.
Pleasant aroma that deters pests.
Attractive color and grain patterns enhance visual appeal.
Lightweight and easy to cut, nail, and sand.
Weathers gracefully to a uniform silver-gray tone.

Disadvantages:

Higher initial cost compared to pine or spruce.
Softer than hardwoods—can dent or scratch more easily.
Requires sealing if maintaining original color is desired.
Variability in quality depending on grade and supplier.
Limited structural strength for heavy-load applications.

How to Choose Cedar Wood

Follow this step-by-step guide when deciding how to choose cedar wood:

Define Your Use Case: Outdoor projects require higher durability grades (e.g., #1 or Clear Vertical Grain). Indoor uses like closet liners can use lower-cost Select grade.
Inspect Each Board: Check for warping, twisting, or cupping. Run your hand over the surface to detect raised grain or rough patches.
Evaluate Knots: Small, tight knots are acceptable. Avoid large, loose, or missing knots (knot holes), which weaken the board 2.
Smell the Wood: Fresh cedar should have a clean, woody scent. Musty odors may indicate mold or poor storage.
Check Moisture Content: Use a moisture meter if possible. If not available, ask the supplier for documentation.
Avoid Sapwood: Heartwood is darker and more durable. Excessive sapwood (light-colored sections) reduces lifespan 7.
Ask About Origin: Confirm whether the wood is sustainably harvested. FSC certification adds assurance 13.

Red Flags to Watch For:

Unusually low prices—may indicate inferior grade or mislabeled species.
Green tint—could mean it’s actually pressure-treated pine falsely advertised as cedar.
No grading stamps or mill markings.
Cracks or splits at the ends of boards.

Price & Market Insights

Cedar wood pricing varies widely based on type, grade, thickness, and location. As of 2024, average retail prices in the U.S. are:

Western Red Cedar (1x6, 8 ft, #2 grade): $4–$6 per linear foot.
Clear Vertical Grain (premium): $8–$12 per linear foot.
Eastern Red Cedar (for trim or lining): $3–$5 per board foot.

Higher costs reflect better appearance and durability. While cedar is pricier than pressure-treated pine (~$2–$3 per linear foot), its lack of chemical treatments and longer service life often justify the investment 14. For budget-conscious buyers, consider using cedar only for exposed surfaces and pairing with less expensive framing materials.

Sourcing & Supplier Tips

Purchase cedar from reputable lumberyards, specialty wood suppliers, or certified online retailers. Local suppliers often carry regionally appropriate stock and can provide milling services. For bulk purchases (e.g., whole-house siding), inquire about bundled pricing or delivery discounts.

If sourcing internationally, verify compliance with CITES regulations for protected species, though most commercial cedar is not restricted 15. Always request sample swatches before committing to large orders. Inspect delivered wood promptly for damage and document any issues with photos for returns.

Maintenance, Safety & Legal Considerations

Cedar requires minimal upkeep but benefits from periodic cleaning with mild soap and water. To retain its original color, reapply a transparent or semi-transparent stain every 1–3 years 16. Sand lightly before recoating to remove graying.

Safety-wise, cedar dust can irritate eyes, skin, and respiratory systems. Wear PPE (mask, goggles, gloves) during cutting and sanding 17. People with asthma or sensitivities should exercise caution.

No major legal restrictions apply to using cedar in residential construction in the U.S. or Canada, provided local building codes are followed. Some municipalities may regulate open-air burning of cedar scraps due to creosote content in smoke.

Conclusion

Choosing the right cedar wood involves balancing aesthetics, durability, and budget. Western Red Cedar remains the top recommendation for most exterior and interior applications due to its proven performance and visual appeal. Focus on high-grade heartwood with low moisture content and minimal defects. While more costly upfront, its natural resistance to decay and insects reduces long-term maintenance needs. By understanding the types, evaluating key specs, and sourcing responsibly, you can make a confident, informed decision that enhances both function and beauty in your project.
