Climate and energy performance in West Whittier-Los Nietos
Los Angeles County sees about 13.3 inches of precipitation and 0.0 inches of snow in a normal year.
Weather at that level is one more reason the flashing and sill pan under a West Whittier-Los Nietos window matter as much as the glass sitting in it.
So ask any West Whittier-Los Nietos contractor how they handle both, not just which brand they carry.
