Rough Lumber
Mason’s Mill & Lumber Co. stocks over 1,000,000 board feet of rough lumber — rough sawn and rough cut hardwoods and softwoods in thicknesses from 4/4 to 16/4. Every board is sourced from the industry’s top domestic and import sawmills and graded to the highest available standard, from FAS and Select to character-grade stock with visible mineral streaks and knots. If a species or size isn’t sitting on our racks in Houston, our supply network can usually source it fast.

Grading Standards:
Every board in our inventory is graded before it reaches our racks, so you know what you’re getting before you order a sample:
FAS (First and Seconds): the highest hardwood grade — largely clear faces, minimal defects.
Select: slightly more character than FAS, still highly usable clear-face yield.
Character grade: natural mineral streaks, sound knots, and heart/sap color variation for a rustic, one-of-a-kind look..
We source exclusively from the industry’s top domestic and import sawmills, so grading is consistent from board to board — critical when you’re matching stock across a large order.
Rough Lumber for Interior and Exterior Applications
Rough lumber from Mason’s Mill goes into:
Interior: furniture, cabinetry, architectural millwork, flooring substrate, paneling, and custom moulding stock (see our 8,000+ moulding profiles)
Exterior: decking, siding, fencing, and ground-contact applications using naturally durable or modified species like Ipe, Accoya®, Kebony®, and Cypress
Structural & specialty: timber-frame beams, mantels, and reclaimed/antique stock for restoration work
Frequently Asked Questions
Rough lumber hasn't been planed — it retains full nominal thickness and visible saw marks. S2S (surfaced two sides) and S4S (surfaced four sides) lumber has been milled smooth and is ready to build with, at a slightly reduced final thickness and a higher price per board foot.
Standard nominal thicknesses run 4/4 (1"), 5/4 (1‑1/4"), 6/4 (1‑1/2"), and 8/4 (2"), up to 16/4 (4") for heavy timbers. Mason's Mill stocks the full range across our hardwood and softwood species.
