Sierra Pacific Windows is part of Sierra Pacific Industries, which sustainably manages over 2 million acres of timberland in California and Washington. Sierra Pacific is amongst the largest millwork producers and lumber companies in the U.S. This gives us something important – control. We build windows and doors in a way that leaves nothing to chance. From planted seed to delivered window and door, every style, every feature, every bit of glazing and cladding are made by people invested in their work, and with the care our founder Red Emmerson instilled when he said, “Don’t pass on bad product.” The result? Nothing but the best gets passed onto you.
