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.
Rough Sawn & Rough Cut Hardwoods and Softwoods
This catalog covers the full range of rough lumber for interior and exterior work — furniture, cabinetry, architectural millwork, decking, siding, and structural applications — including Kebony®, thermally modified and FSC®-certified options like Accoya® and Thermory for projects that need 25+ years of durability without chemical treatment.

Aromatic Cedar 4/4 Rough Lumber (Indiana)
$
Regarded as excellent in resistance to both decay and insect attack, aromatic red cedar is frequently used for fence posts used in direct ground contact with no pre-treating of the wood.
Overall, aromatic red cedar is easy to work, notwithstanding any knots or irregularities present in the wood. It reportedly has a high silica content, which can dull cutters. Aromatic red cedar glues and finishes well, though in many applications, the wood is left unfinished to preserve its aromatic properties.
Cedar has a distinct and tell-tale scent: the wood is commonly used in closets and chests to repel moths and other insects. Though eastern red cedar trees are widely distributed throughout the eastern half of the United States, it is a very slow-growing species, and most trees harvested tend to be fairly small in diameter. Because of this, aromatic red cedar boards tend to be knotty and narrow.
In rustic or knotty grades of lumber, there will be a percentage of degrade during the milling process. Some knots may shake lose and/or fall out during the milling process. Mason’s Mill is not liable for these defects in moldings produced from knotty grades of lumber.
Mason’s Mill and Lumber will not be responsible or issue a credit for any cup, warp, twist or splitting that occurs in any custom cut Fir or Cedar boards or beams. These issues can be present in material cut from larger beams and timbers and need to be accounted for by the buyer when determining if Fir or Cedar is appropriate for the intended application. Cedar and Fir products will typically have knots.

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.

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.
