Grain Pattern

Mostly straight, coarse grain with prominent vertical growth bands; knots and small knot clusters are visible. Appears flat-sawn or plain-sawn.

Color & Appearance

Value & Age

Estimated Market ValueNot an official valuation

Approximately $6–15 per board foot for clear, sound cedar; architectural installed material may cost substantially 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 timber itself cannot be dated visually; the clean surface and intact finish suggest relatively recent installation, likely under 20 years.

Common Uses

Exterior siding, beams, trim, doors, fencing, decking, shingles, furniture, and boat components.

Geographic Origin

Native to the Pacific Northwest and coastal British Columbia, extending into northern California and the inland Northwest.

Workability

Very easy to cut, plane, sand, glue, and fasten, though its softness causes dents and fibers may compress around fasteners.

Finish Recommendations

Use a penetrating exterior oil or high-quality stain with UV protection; clean and lightly sand before recoating. Film finishes require careful maintenance outdoors.

Notable Features

Lightweight, dimensionally stable, aromatic, and naturally oily; knots and resin pockets are characteristic.
