The author of this consumer handbook intentionally went to work undercover for a period of two years to write this book after being ripped off by one of the Big Box contractors that specializes in window replacements and also siding, soffit, gutters, kitchen refacing, countertops, patio rooms and roofing. He worked an average of 60-90 days, going through the training cycle and management training in the field. This covered all the major Big Box stores, except one, and many independent contractors.In order to collect as much information as possible he also scheduled several appointments in two different homes to listen to the pitches of the in-home salespeople for their products, over this same time-period.What he found out is that you, the consumer, pay excessively, especially when you use Big Box store services, for you are buying only the name, not a superior product.
