S4S Lumber

Who are they for? These are ideal for those who aren’t equipped with the necessary tools to flatten and straighten boards.

The term "surfaced" or "dressed" refers to a piece of wood that has been milled. To achieve the necessary dimensions, we select a larger board to work from. Both faces and edges are then surfaced so you can be assured that the board is flat and straight. These boards are available in specific sizes.

For example: 3/4” x 5-1/4” x 24”

Rough Cut Lumber

Who are they for? These are ideal for those who enjoy working with machinery or hand tools to mill their own boards.

We use this term to describe boards that require additional milling. Rough cut lumber have been run through the planer to show the grain however they have not been dressed. You will need to mill both faces and edges. Rough cut lumber are available in specific lengths with varying widths.

For example: 4/4 x (5-6”) x 24”

You will receive a board that is just shy of an inch thick, with a width in the range of 5-6”, and is 24” long.

Excellent quality

Purchased the lumber to make two coffee table/pet kennels. Exactly what I wanted/needed at a fair price and received promptly. Thanks.

True and Straight

Boards were impressive in their moisture content as well as delivered ready for glue ups. Colour matching was well done.
