These Are the Most Memorable Moments Chip and Joanna Gaines Captured on Fixer Upper

Remodeling a corrugated metal barn into a forever home for U.S. marine TJ and his girlfriend, Stephanie, was certainly special for the Gaineses. But when TJ got down on one knee and popped the question, this sweet season 5 episode became even more memorable. “I know we’ve been on a lot of great adventures, and I think this marks the beginning of our greatest adventure,” he said in front of the tearful crowd.

After losing her husband of 37 years to cancer, widow Patti Baker turned to Chip and Jo to find and design a home in Waco, Texas, that would allow her to be closer to her adult sons. Baker was thrilled to see her humble bungalow during the final reveal, but the true happy ending happened after the cameras stopped rolling. PEOPLE later revealed that Baker reconnected with a former acquaintance shortly after filming and the pair ended up tying the knot in August 2017.

In season five, Joanna jumped at the chance to design a home for her sister Mary Kay McCall, who recently moved back to Waco after nine years away. “Chip and I have been doing houses for fifteen years now, and I would say this house is the one I’m most excited about,” she said. Mary Kay also shared in the episode that she was pregnant with her sixth child, a girl the family welcomed in January.

The season four finale was a favorite for Fixer Upper fans. Not only did the famous hosts transform a $12,500 shack into a stunning family home for their executive producer, Michael Matsumoto, and his wife, the new homeowners also discovered they had twin babies on the way. Even sweeter, the little ones were born just a few days before the episode aired.

Way back in season one, the Gaineses took on a disastrous property for their longtime woodworker, Clint Harp and his wife, Kelly. Chip and Joanna brought the dilapidated house back to life for their friends, but it was the special touches Clint built himself — like the door, stairs and kitchen island — that made the reveal that much more meaningful.

This project was extra sweet for the Gaines family. Chip and Joanna debuted their bakery, Silos Baking Co., on season four of the series and chose some very special guests for their first customers: their kids! Although the cute crew was excited, Joanna admitted there was really only one thing they cared about: “There’s a lot that went into this thing and I think for them, all they saw were the cupcakes,” she said.

The HGTV stars, who are expecting baby number five, teamed up with former football star Tim Tebow to design an Americans with Disabilities Act (ADA)-compliant home for Melissa and Jody Copp and their two sons, Calan and Lawson, who are both wheelchair users. After the episode aired in 2018, the Gaines took it one step further and rallied fans to pay off the family’s mortgage.

During the final season of the show, the Gaineses decided to take on a project a little closer to home. They built a chicken coop, chicken run and this super-stunning shed in the backyard of their farmhouse. They tackled the renovations alongside their four children, Drake, 12, Ella, 11, Duke, 9, and Emmie Kay, 7, who each had a job in the makeover.

With only a few episodes left in the series, the Gaineses are sure to tug at fans heart strings. Tune into Fixer Upper Tuesdays at 9PM EST on HGTV.
