The show provides expert real estate and design advice and general contractors, who are given a $2,000 budget for materials to get a maximum offer for the house. To add excitement to the show, the renovations generally take place over a period of three to seven days, before the home's open house, generally spread out over the course of three or four weeks. The show pays the contractor's fees and the salaries of the carpenters, landscapers, painters, plumbers, and other workers. Most changes are cosmetic, but some require drastic demolition and reconstruction.
