The season finale of HGTV's hit show "Celebrity IOU" aired on Monday night, marking the end of the first season of Drew and Jonathan Scott's most recent show.

The show combines the fun of an HGTV renovation with the best celebrity personalities, providing stars like Brad Pitt, Michael Bublé, and Rebel Wilson with the opportunity to give back to people they love.

Jeremy Renner starred in the finale, giving his mom Valerie a dream home makeover on the show.

Renner and his siblings bought their mom a house in Los Angeles so she could be closer to her grandchildren

Renner and his mother are extremely close, in part because she was young when she had him.

She had him when she was still a teenager, giving up everything to take care of him.

"We kind of grew up together," Valerie said of their mother-son relationship.

Valerie had been living five hours south of Los Angeles, so the move will allow her to watch her grandchildren grow up.

Renner had already purchased the home before filming the episode of "Celebrity IOU," but it needed a lot of work.

In the episode, Renner said he wanted the house to be a place "for all the grandkids and all of us to come be with her and visit because she's the rock of the family."

"She's given her life to us, so we really want to take care of her," he added.

Renner has actually worked on over 25 houses, so he's no stranger to the renovation process

Renner's experience in the field allowed him to work with the Scotts more efficiently, ensuring his mom's home would suit her needs.

The house was pretty before the renovation, but much of it looked dated because it was built in the 1970s.

For instance, an entire wall of the home was made of mirrors.

Likewise, the kitchen was small and cramped, which wouldn't suit Valerie's needs.

She is an avid baker, and she hoped to spend time in the kitchen with her grandkids moving forward.

Renner and the Scotts decided to gut the living room and kitchen, totally transforming the main level of the home so it could become a haven for their whole family.

The trio only had five weeks to renovate the home

Valerie was staying with Renner during the construction process, and she had no idea her son was renovating her home.

Renner was hands-on with the demolition process, grabbing a sledgehammer alongside the Scotts to get the house ready for the build.

His experience with renovations and stunts from movie sets helped him make quick work of the demolition.

Renner stepped back from the renovation after the demolition as he had to go film a movie, letting the Scotts take over.

But he rejoined them when it was time to reveal the finished project to his mom.

The living room was given a total makeover, with the dated mirrored wall being replaced by a sleek marble fireplace.

The living room is now modern and inviting, making it a perfect space for entertaining kids and adults alike.

The sleek vibe continued into the kitchen, which the Scotts and Renner made much larger and more efficient.

The oven and sink are the ideal sizes for Valerie's cooking project, and the two-tone cabinetry gives it a fresh feel.

The large island will allow Valerie and her grandchildren to bake together without feeling cramped as well.

The Scotts were even able to add an additional guest room to the home, so Valerie's grandchildren can have sleepovers at her house.

Valerie was completely surprised by the renovation

Renner brought his mom to the home under the guise of looking at what she would want to change in the space. She had no idea the renovation had already been completed.

"I don't think this is my house, Jeremy," Valerie said when she saw the new space, crying when she realized what her son had done.

"My life has come full circle now," she said of the renovation. "I can have all my grandchildren here. I can have all my children here. We can make so many memories. I couldn't be happier."

"My mom means everything to me," Renner said of Valerie. "She's given me everything."

"She's made me a better parent," he added. "All the things she's sacrificed was always for us, for her kids."

He continued: "My heart is full already, and then to bring pure joy and love to somebody, especially my momma, there's no better feeling than that."
