In 2007, the first full year of the housing downturn that continues to put a drag on the economy, many remodeling companies had a rough time. Not so, however, for most members of the Big50 Class of 2008. While those around them were experiencing revenue slides of 25% or more, most of this year's Big50 enjoyed strong growth; the few exceptions managed to shrink in size while maintaining or increasing net profit. Unless otherwise noted, all data are for fiscal 2007 and for companies with less than $10 million in 2007 revenue.
