Sierra Pacific Windows is part of Sierra Pacific Industries, the largest millwork producer and the second-largest lumber company in the U.S. Sierra Pacific Industries owns over 2 million acres of timberland in California and Washington. 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 a bad product.” The result? Nothing but the best gets passed onto you.
