Composite vs. Wood Deck Cost in Pasadena: Trex, TimberTech, and the Best Deck Builders
Building a new deck is an investment that enhances both the value and enjoyment of your Pasadena home. In our sunny, dry climate, the biggest question is no longer if you should build a deck, but what material should you use?
The decision boils down to initial wood deck cost versus the long-term, low-maintenance value of composite decking from industry leaders like Trex and TimberTech.
At Gaga US Construction, we are experienced Pasadena deck builders. This guide breaks down material costs, durability, and the crucial local regulations—like those in Pasadena’s historic districts—that you must navigate.
Pillar 1: Pasadena’s Deck Regulations
Before a single board is laid, local zoning codes dictate what you can build. Ignoring these rules is the quickest way to halt a project.
The Critical 18-Inch Rule
Permit Exempt: Decks placed directly upon the finish grade that do not exceed a height of 18 inches are generally exempt from standard setbacks and building permits.
Permit Required: If your deck is over 18 inches off the ground, it is considered a structure. It requires a building permit, must meet full zoning setbacks, and requires compliant safety railings.
The Historic District Hurdle (The COA)
If you live in Bungalow Heaven, Garfield Heights, or another Landmark District, you cannot simply build. You must obtain a Certificate of Appropriateness (COA).
Warning: Historic districts often discourage composite materials. We can guide you through the COA process to find materials (usually high-grade Redwood or Cedar) that comply with the district's strict aesthetic standards.
Pillar 2: Cost Comparison (Wood vs. Composite)
The material choice involves a direct trade-off between upfront expense and long-term maintenance costs.
| Material | Avg. Cost (Installed) | Pros & Cons |
|---|---|---|
| Natural Wood (Redwood / Cedar) |
Lowest Upfront | Pros: Authentic look; allowed in Historic Districts. Cons: Requires staining every 1-3 years; prone to dry rot/termites. |
| Trex (Composite) |
Mid-Range ($35-$50/sq ft) | Pros: 95% recycled; low maintenance. Cons: Can get hot in direct sun; sensitive to scratches. |
| TimberTech (PVC Capped) |
Premium Cost | Pros: Superior fade resistance; cooler on feet (AZEK line). Cons: Highest material cost. |
Trex vs. TimberTech: The Breakdown
- Trex: Excellent sustainability and affordability (Enhance line). Best for budget-conscious projects requiring low maintenance.
- TimberTech (AZEK): A fully synthetic PVC line (no wood fibers). This makes it the champion for Pasadena's intense sun, offering superior resistance to fading and moisture.
Pillar 3: Design & Longevity
We ensure the framing and deck footings meet the California Residential Code for structural soundness.
The Foundation (Framing)
No matter the surface material, the frame must be Pressure-Treated Lumber. We prioritize proper flashing and ledger board installation to prevent water intrusion into your main house—the #1 cause of rot repair.
Sun Exposure & Safety
- Heat Mitigation: For south-facing decks with all-day sun, we recommend lighter colors or PVC-based boards (TimberTech AZEK) which retain less heat than dense composites.
- Railings: For decks over 30 inches high, railings are mandatory. We install durable powder-coated aluminum or cable rail systems that meet the 42-inch height requirement.
