Where to Buy Lumber for Custom Decks in Flagstaff

Looking to build a custom wood deck and need lumber that fits your design—not just whatever the hardware store carries? At AP Sawmill in Flagstaff, we supply custom-cut, full-dimension lumber ideal for decks, porches, pergolas, and outdoor living spaces.

We specialize in rough-sawn Ponderosa Pine, milled on-site from locally salvaged logs, giving you high-quality wood that’s beautiful, durable, and unique to Northern Arizona.

Why Use Custom-Milled Lumber for Decks?

Whether you're building a rustic cabin deck or upgrading a modern patio, custom-milled lumber gives you options that off-the-shelf materials can’t:

1. True Full-Dimension Cuts

Our boards are cut to their actual thickness and width. For example, a true 2x6 from AP Sawmill measures a full 2 inches by 6 inches—not the smaller planed dimensions you find at big box stores.

2. Longer and Custom Lengths

Need an 18-foot board with no seams? A beam for a wraparound deck? We can cut longer and wider than standard retailers.

3. Rough-Sawn Texture

Our rough-sawn finish adds grip and visual texture, perfect for rustic-style decks and natural outdoor environments.

4. Locally Sourced

Our Ponderosa Pine lumber is milled in Flagstaff from local trees removed during fire mitigation, hazard tree removal, and construction clearings. It’s sustainable and supports Arizona forests.

Common Lumber Sizes for Deck Construction

We regularly cut and supply the following lumber sizes for deck framing and surfaces:

• 2x6, 2x8, 2x10: Ideal for deck planking and joists

• 4x4, 6x6: Common for posts and structural supports

• Custom beams: Available for longer spans, pergolas, and railings

• 1x6, 1x8, random-width boards: Used for creative decking layouts, fascia, and trim

Let us know your plans and we’ll help you spec the right sizes for code, load, and visual appeal.

Can I Use Rough-Cut Lumber for a Deck?

Yes—rough-cut lumber is a great choice for decks when properly installed and finished. It provides:

• A stronger, thicker board for heavy-use areas

• A rustic, natural look that blends with outdoor spaces

• A more affordable option compared to many treated or composite products

We recommend sealing or staining your deck after installation to protect against moisture and UV.

Custom Orders for Unique Deck Designs

No two decks are the same—and we’re set up to help you create something unique.

Whether you need:

• Extra-long or extra-wide planks

• Matching live-edge slabs for benches or rail caps

• Beams for a pergola or shade structure

• Decorative board and batten skirting

We can cut to order based on your drawings, material list, or even just your vision.
