Wood vs Composite Decking: What’s Best for San Diego Homes?

San Diego’s year-round sunshine is perfect for outdoor living — but that same sun (plus salty coastal air) is brutal on your deck. Here’s how to choose the right material.

I’ve built dozens of decks across San Diego County, from beachside homes in Cardiff to hillside properties in La Mesa. And the question I get more than any other is: “Should I go with wood or composite?”

The honest answer is: it depends on your budget, your location, and how much maintenance you’re willing to do. But I’ll break it down so you can make the right call.

Cost Comparison: The Real Numbers

Wood Decking:

• Pressure-treated pine: $15–$25 per sq ft (materials only)
• Cedar: $25–$40 per sq ft
• Redwood: $30–$50 per sq ft
• Ipe (Brazilian hardwood): $40–$65 per sq ft

Installed, you’re looking at $35–$85 per square foot for a wood deck in San Diego.

Composite Decking:

• Trex Enhance (entry-level): $30–$45 per sq ft installed
• Trex Transcend (premium): $45–$60 per sq ft installed
• TimberTech AZEK (PVC/composite): $50–$70 per sq ft installed
• Fiberon / Deckorators: $35–$55 per sq ft installed

Composite runs about 20–40% more upfront than pressure-treated wood. But that gap closes fast when you factor in maintenance.

Maintenance: The 10-Year Reality Check

Wood Deck Maintenance:

• Sanding and resealing every 1–2 years
• Stain touch-ups as the sun bleaches the finish
• Board replacement — expect 5–15% of boards over 10 years
• Annual cleaning with specialized wood cleaners

Over 10 years: $3,000–$8,000 for a 300 sq ft wood deck.

Composite Deck Maintenance:

• Soap and water cleaning twice a year
• That’s it.

Over 10 years: $200 in cleaning supplies. No sanding. No staining. No sealing. No warping. No termites.

Longevity: Which Lasts Longer in San Diego?

Wood Lifespan:

• Pressure-treated pine: 10–15 years
• Cedar: 15–20 years with diligent maintenance
• Redwood: 20–25 years
• Ipe: 25–40+ years

Composite Lifespan:

• Trex and similar: 25–30+ years
• PVC decking (TimberTech AZEK): 30–50 years

Most composite comes with a 25–50 year manufacturer warranty. Try getting that on wood.

San Diego Climate: UV and Salt Air Factors

UV exposure: San Diego gets 260+ sunny days per year with UV index regularly hitting 10+. This bleaches wood rapidly — even stained redwood grays within 18 months. Composite with UV inhibitors holds color significantly better.

Salt air: In Pacific Beach, La Jolla, Encinitas, Imperial Beach — salt corrodes fasteners and accelerates wood aging. Composite boards are impervious to salt damage.

Temperature swings: Inland areas like El Cajon, Santee, Escondido see 40-degree daily swings. Wood cracks and splits. Composite handles thermal movement better.

The pros at United Pro Builders can walk you through which materials perform best for your specific neighborhood.

Resale Value: What Do Buyers Want?

A wood deck recoups about 65–72% of its cost at resale in the Pacific region. Composite recoups 60–68%.

But San Diego buyers increasingly prefer low-maintenance outdoor spaces. A composite deck in a coastal neighborhood can actually sell a home faster because buyers know they won’t be spending weekends sanding and staining.

For luxury homes ($1M+), composite has essentially become the expectation.

The Verdict

Go with wood if:

• You’re on a tight upfront budget
• You love the natural look and don’t mind maintaining it
• You’re in an inland area with less UV and salt exposure

Go with composite if:

• You want to build it once and forget about it
• You live near the coast
• You’re planning to stay 10+ years
• You want a consistent look without seasonal fading

My recommendation for most San Diego homeowners? Composite is worth the premium. Our climate is simply too harsh on wood long-term.

Final Thoughts

The right deck transforms how you use your outdoor space. Whether you choose wood or composite, the most important decision isn’t the material — it’s the contractor building it. Look for a licensed contractor with real deck experience, check their CSLB license, and ask to see completed projects.
