Planning an outdoor project like a new deck, fence, or garden bed? You’ve likely considered lumber, with naturally beautiful redwood and robust, chemically-treated pressure-treated wood as top contenders. Deciding which is better, redwood or pressure treated wood, can feel tricky. This guide clarifies their unique qualities, helping you pick the perfect material for your vision.

Redwood: Natural Beauty & Resilience
Sourced from majestic redwood trees, this timber is celebrated for its stunning natural appearance and inherent durability. It’s a premium choice for those valuing organic beauty and long-lasting resilience.
Why Choose Redwood?
- Natural Resistance: Naturally resists rot, decay, and insects thanks to its oils and tannins.
- Gorgeous Aesthetics: Rich, reddish-brown color adds warmth. Can be sealed to maintain hue or allowed to weather to silver-grey.
- Exceptional Stability: Less prone to warping, twisting, or checking.
- Lightweight: Simplifies handling and installation.
- Sustainable Option: Environmentally friendly if sourced from certified, managed forests.
- Long Lifespan: With proper care, can last 20-30+ years.
Considerations for Redwood
- Higher Price Tag: Significantly more expensive.
- Availability: Specific dimensions/grades can be harder to find.
- Maintenance for Color: Requires regular sealing to preserve vibrant color; otherwise, it fades.
Pressure-Treated Wood: The Durable Workhorse
Pressure-treated (PT) wood refers to various woods (e.g., pine, fir) infused with chemical preservatives under high pressure. This makes it incredibly tough against the elements, ideal for challenging outdoor conditions.
Why Choose Pressure-Treated Wood?
- Budget-Friendly: Typically much more affordable than redwood.
- Widely Available: Easily found in hardware or lumberyards.
- Superior Durability: Chemical treatment offers excellent resistance to rot, fungal decay, and insects, perfect for ground contact.
- Structural Strength: Robust structural integrity for framing decks and fences.
Considerations for Pressure-Treated Wood
- Appearance: New PT wood has a greenish tint, weathering to dull grey. Needs effort for aesthetic appeal.
- Chemicals: Modern treatments are safer, but handling requires gloves/mask. Never burn scraps; dispose of properly.
- Prone to Warping/Cracking: Can be susceptible to warping, twisting, and checking as it dries.
- Heavier: Absorbed chemicals and moisture make it heavier.
Redwood vs. Pressure-Treated Wood: A Side-by-Side Look
To help you decide which is better, redwood or pressure treated wood, consider these key differences:
- Cost: PT wood is economical; redwood is premium.
- Lifespan: Redwood (20-30+ years) often longer than PT (15-20 years), with maintenance extending both.
- Appearance: Redwood offers natural, rich tones. PT wood starts green, fades to grey, needs more finishing effort.
- Maintenance: Both benefit from sealing. Redwood for color, PT wood for moisture protection.
- Environmental Impact: Certified redwood is natural/sustainable. PT wood’s chemicals require careful handling/disposal.
- Ground Contact: PT wood is engineered for direct ground contact; redwood performs best above ground unless highly protected.
Making Your Best Choice
Your ideal wood choice hinges on your project’s specific needs and priorities:
- Budget: PT wood is economical; redwood is a luxury investment.
- Aesthetics: Natural redwood charm vs. transformable PT wood with finishes.
- Location & Purpose: PT wood for ground contact/structural; redwood for visible, above-ground beauty.
- Maintenance & Longevity: Both need care. Redwood offers natural longevity; PT wood offers treated longevity.
- Environmental Values: Choose certified redwood for sustainability; understand PT wood’s chemical handling.
Important Tips for Both Woods
- Handling PT Wood: Wear gloves, eye protection, and a dust mask. Never burn scraps; dispose of properly.
- Raised Garden Beds: For edible gardens, lining PT wood beds with a thick plastic barrier is a precaution. Redwood is a safe natural alternative.
- Redwood Sourcing: Look for FSC certification for sustainably managed forests.
Your Questions Answered
- Q: Can I use pressure-treated wood for raised garden beds?
- A: Yes, modern PT wood is generally safe. For edible plants, lining with a plastic barrier is a common precaution. Redwood is a natural alternative.
- Q: Which lasts longer, redwood or pressure-treated wood?
- A: Redwood (20-30+ years) often lasts longer due to natural resistance. PT wood (15-20 years). Both benefit from diligent care.
- Q: Is redwood waterproof?
- A: Not waterproof, but highly resistant to rot/decay. Sealing is recommended for outdoor use to protect and extend lifespan.
- Q: Can you paint pressure-treated wood?
- A: Yes, but let it dry thoroughly after installation (weeks to months). Applying paint or stain too soon leads to peeling.
- Q: Is redwood stronger than pressure-treated wood?
- A: PT wood can be structurally stronger for load-bearing. Redwood is more dimensionally stable, resisting warping better for long-term appearance.
Your Project, Your Perfect Wood
Ultimately, the “better” wood — redwood or pressure-treated — hinges on your project’s demands, budget, and personal preferences. Both offer incredible benefits for outdoor living. By understanding their pros and cons, you’re now equipped to make an informed decision and create something beautiful and long-lasting!
