Value & Age

Estimated Market ValueNot an official valuation

Approximately $2–$6 per board foot for ordinary surfaced Douglas fir; clearer or reclaimed stock may cost more.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
The board appears recently milled or lightly weathered; visible wear does not reliably indicate tree or board age.

Common Uses

Framing, beams, shelving, furniture, millwork, doors, flooring, plywood, and general construction.

Geographic Origin

Native to western North America, especially the Pacific Northwest and interior western regions.

Workability

Generally easy to saw, plane, sand, glue, nail, and screw. Resin, uneven earlywood/latewood hardness, and occasional tear-out can affect machining.

Finish Recommendations

Sand progressively and seal resinous areas if present; oil, shellac, lacquer, or polyurethane are suitable. A conditioner or sanding sealer can improve uniformity.

Notable Features

Lightweight with prominent growth-ring contrast and good strength-to-weight ratio; resin pockets may occur.
