Red cedar wood decking is a popular choice for American homeowners seeking a natural, durable, and visually appealing outdoor living space. Known for its natural oils that resist decay and insects, red cedar offers long-lasting performance with a distinctive warm color that ages beautifully. This article explores the key benefits, potential downsides, maintenance requirements, and practical installation considerations to help readers make an informed decision about red cedar decking.
What Makes Red Cedar Decking Distinct
Red cedar, derived from Thuja plicata and related species, is prized for its lightweight strength and natural resistance to moisture. Its cellular structure allows it to absorb finishes evenly, while its resinous oils deter insects and fungal growth. When properly milled, red cedar features tight grain, minimal shrinkage, and a smooth, splinter-free surface. Aesthetically, it offers a warm reddish-brown hue that can be preserved with sealants or left to weather to a silver-gray patina over time.
Advantages Of Red Cedar Decking
- Natural Durability: Cedar contains natural oils that resist rot and insect damage, reducing the need for chemical preservatives.
- Dimensional Stability: Cedar resists warping and shrinking better than many softwoods, contributing to a stable deck frame.
- Ease Of Workability: Soft to cut and nail, allowing for precise, clean joints and fewer tool wear issues.
- Aesthetic Appeal: Rich color, fine grain, and a subtle aroma enhance outdoor ambiance and curb appeal.
- Versatile Finishes: Accepts stains, paints, or clear sealers, enabling a range of looks from natural to bold.
Disadvantages And Considerations
- Cost: Red cedar generally costs more upfront than common softwoods like pressure-treated pine.
- Color Change: Without protection, cedar will weather to a gray tone; consistent sealing helps maintain the original hue.
- Maintenance Needs: Regular cleaning and periodic sealing or staining are recommended to maximize longevity.
- Supplier Variability: Quality and species naming can vary by region; confirm species, grade, and certification.
- Limited Availability: Depending on location, sourcing may require planning and lead times due to demand.
Maintenance, Finishes, And Longevity
Proper maintenance is essential for maximizing the lifespan of red cedar decking. Start with a proactive cleaning schedule to remove mold, mildew, and debris that can trap moisture. Use a mild detergent solution and a soft-bristle brush, avoiding high-pressure washers that can damage the wood’s surface. After cleaning, apply a protective finish tailored to cedar—clear sealers for natural color or semi-transparent stains to preserve warmth while providing UV protection. Reapply every 2–5 years, depending on climate exposure and product recommendations. In shaded, humid regions, more frequent maintenance may be necessary.
Finishes For Different Aesthetics
- Clear Sealers: Preserve natural color and grain; best for those who want minimal tint.
- Semi-Transparent Stains: Add color while still showing the wood’s grain; offers UV protection.
- Solid Stains/Paint: Completely cover the wood; ideal for color customization and longer intervals between maintenance.
Installation Tips And Techniques
Proper installation ensures that red cedar decking performs well for years. Use corrosion-resistant fasteners such as stainless steel or coated deck screws to withstand outdoor conditions. Leave adequate spacing between boards to allow for expansion and drainage; typical gaps range from 1/8 inch to 1/4 inch depending on climate and decking width. Employ a solid framing system with treated lumber or durable timber to minimize movement. Consider hidden fastening systems for a clean, uniform surface. If applying finishes, do so after installation and ensure all surfaces are dry and clean beforehand.
Cost Considerations And Budgeting
The upfront cost of red cedar decking includes material, fasteners, and finishing. In many markets, red cedar prices are higher than pressure-treated wood but lower than tropical hardwoods. Homeowners should budget for:
- Material Costs: Cedar boards, typically sold in widths from 5.5 inches to 6 inches for decking planks.
- Hardware And Fasteners: Stainless or coated screws to resist corrosion.
- Finishes: Sealers or stains, plus brushes, squeegees, and applicators.
- Maintenance: Yearly or biannual upkeep impacts long-term cost savings by extending deck life.
Environmental And Sustainability Considerations
Consumers increasingly prioritize responsibly sourced timber. Look for Cedar sourced from forests with certification programs that promote sustainable forestry practices. Red cedar’s natural durability can reduce maintenance-related chemical exposure, aligning with low-toxicity preferences. However, avoid over-application of finishes with environmentally harmful solvents. Proper disposal of used sealers and cleaners should follow local regulations.
Common Alternatives To Red Cedar Decking
- Western Red Cedar: Similar aesthetic with sometimes different resin content and color tone.
- Pressure-Treated Pine: Lower cost, readily available, but may require more frequent finishing and treatment.
- Low maintenance and high durability but with a different look and higher initial cost.
- Very durable but heavier and more expensive; requires careful installation and maintenance.
Sourcing And Quality Indicators
When selecting red cedar, verify the species name, grade, and moisture content. High-grade boards have fewer knots and defects, contributing to a smoother finish. Request kiln-dried stock to minimize movement after installation. Check for certification labels from credible forestry programs and review supplier warranties. Ask about pressurization treatment and post-harvest handling to ensure longevity in harsh climates.
Practical Maintenance Schedule
- Inspect annually for checks, cracks, or loose fasteners.
- Clean twice a year with a cedar-safe detergent.
- Apply finish after cleaning and drying; follow product guidelines for recoating intervals.
- Re-seal or restain every 2–5 years based on sun exposure and wear patterns.
Frequently Asked Questions
- Does red cedar deck require sealing? Sealing is recommended to protect color and UV resistance, but some prefer the natural weathered look with periodic maintenance.
- How long does a red cedar deck last? With proper upkeep, a red cedar deck can last 20–40 years depending on climate and maintenance frequency.
- Can I install red cedar over a concrete slab? Yes, with proper moisture barriers and a solid framing system to prevent moisture transfer and ensure stability.
