Ty Murray and his wife Jewel have seen a lot of things in their careers.

But nothing compares to what they experienced last November when they filmed this Sunday’s episode of “Extreme Makeover: Home Edition,” which airs on ABC at 8 p.m. ET.

“It’s unbelievable,” Murray said. “If they didn’t have this show, I would tell you that you couldn’t do it in six months.”

“They get things done in a shocking amount of time,” added Jewel.

The nine-time World Champion and his multi-platinum selling wife spent a week in North Carolina assisting a crew of professionals, all of whom volunteer their time and materials, as they built a brand-new, state-of-the-art home for a family of five.

According to Murray, crews move everything out of the current home, categorize it, tear down the old house (including the cement slab), haul it away, pour a new concrete foundation, build the new home, landscape the exterior, redecorate the interior and then move the family’s belongings back in.

Murray said the house isn’t partially completed at week’s end…it is fully operational. Special chemicals are used when pouring the foundation so that the concrete sets immediately and is ready for the construction to begin.

Gone are all the old appliances, replaced with new modern amenities.

In fact, Murray poked around and said that not one detail was overlooked. For example, in the laundry room they not only replaced the old washer and dryer, but they also stocked the shelf above with detergent, bleach and fabric softener.

The same was true in the kitchen. In addition to the major appliances, there was a coffeemaker, blender, cookware, serving ware and all the necessary cleaning supplies underneath the sink.

“When they come back,” said Murray, “they don’t have to do anything. … It’s all fully suited to their needs.” The beneficiaries, the Creasey family, were away on an all-expenses-paid trip to Disney World.

The mother of the family is battling terminal cancer, and the “beautiful home that anyone would live in” relieves her and her husband the burden of providing their three daughters a place to live.

In order to accomplish everything in a week’s time, not a moment is spared.

Various inspectors are on hand to immediately approve each phase of the project, and in addition to professional contractors, carpenters, roofers, electricians, plumbers and landscapers, Murray said the show’s producers also utilize an extensive team of volunteers from the local community.

“It doesn’t change one family’s life,” Jewel said. “It changed an entire community, and it shows that when the chips are down we help our neighbors.”

Murray helped with various tasks, ranging from installing cabinets to building a rock fireplace on the back patio, while Jewel had tasks of her own. She also paid a visit to a local elementary school where the mother of the family happens to teach.

Another important of the process is crowd control.

“Thousands of people come out just to watch,” said Murray, who almost three months later is just as amazed, “and I mean thousands. You look beyond the barrier and it just stretches as far as you can see.

“I guess people who watch the show might know all that, but to see it and experience it was unbelievable. I don’t know how else to say it.”
