Material lead times shift seasonally and across product lines. Knowing what's ready-stock vs. ordered-from-factory affects your project timeline. Here's the honest 2026 picture for California.
Hardie ColorPlus standard palette: 1–3 weeks
Hardie's most common ColorPlus colors — Arctic White, Iron Gray, Khaki Brown, and the most-spec'd recent palette — are typically ready-stock at California distributors and ship within a week of order. Standard HardiePlank profiles in standard colors are predictable lead-time wins.
Hardie ColorPlus less-common palette: 3–6 weeks
Less-common ColorPlus colors, recently-introduced palette additions, or anything outside the dealer's standing stock require factory order with longer lead time. Plan accordingly if you're spec'ing a less-common color.
Hardie Reveal, Aspyre, and Architectural Collection: 4–8 weeks
Hardie's premium product lines — Reveal panels, Aspyre wood-look, Architectural Collection — are typically not stocked at standard distributors and require longer factory lead time. On custom projects spec'ing these products, we plan the longer lead time into the schedule.
LP SmartSide standard products: 1–3 weeks
LP SmartSide lap and trim in standard primed finish are typically ready-stock at California distributors. Pre-finished SmartSide colors have longer lead times depending on color choice and factory schedule.
Hardie Trim and accessory pieces: 1–3 weeks
Standard Hardie Trim sizes and accessory pieces (corner boards, frieze, fascia) are typically ready-stock. Custom trim profile sizes require factory order with longer lead time.
Seasonal effects
Peak season (April–September) lead times can extend 1–3 weeks beyond the typical baseline. Off-peak season often runs at or below baseline. Manufacturer schedules occasionally introduce specific shortages — we monitor and adjust scheduling when they appear.
How we plan around lead times
At estimate signing, we order long-lead-time materials so they're on-site or imminent when the project starts. Standard-stock materials are typically delivered the week before or at project start. We never start a project without confirmed material delivery; that's a recipe for incomplete work and exposed framing.

FAQ
Quick Answers
Hardie Architectural Collection and certain Reveal panel orders can run 6–10 weeks in peak season; we plan around them.
Sierra Siding doesn't run material inventory — that's the distributor's role. We work with major California Hardie and LP distributors who know our project pacing.
We're upfront about lead times at signing. If a material isn't going to be ready on time, we'll either delay project start or swap to a comparable spec that's available — your call, with our honest recommendation.
