SWANSEA – If this doesn’t get a 12-year-old Celtics fan to keep his room clean, nothing will.

At about 3 p.m. on Thursday, Jace Peixoto was treated to a long-awaited look at his redesigned bedroom. The makeover has a distinctively Boston Celtics look, with a 5-square foot piece of the TF Garden parquet floor from then 2008 championship season serving as its literal and figurative centerpiece.

The makeover is courtesy of the Celtics themselves, the reward for Jace, a Case Junior High sixth grader, and his mother Tabitha Dalton-Peixoto winning a Boston Celtics/Instagram contest advertised during a televised game last year. While the contest was technically for pictures, Tabitha submitted a short video of her giving Jace Celtics tickets as an early Christmas present last December

When Tabitha entered, she didn’t have winning on her mind. “I thought if they could just like it (on Instagram), it would make his year,” she said.”

The Celtics did more than like it. They loved it, as in congrats, Peixotos, you’ve won the grand prize – the room-of-their-choice makeover. The Peixotos learned they had won on April 20, Jace’s 12th birthday.

“I was just speechless,” Jace said while watching Boston defeat Lebron James and the Cleveland Cavaliers in Game 5 of the Eastern Conference finals on Wednesday night. “I couldn’t even express how I felt.”

His feelings were similar on Friday when his renovated, Celtics-ized room was unveiled, amid a fair amount of pomp. Newspapers. A TV station. A Celtics video crew. Celtics dancers. Lucky the Leprechaun, the Celtics bubbly mascot. Lots of family and friends. Lots of food.

When the bedroom door was opened, Jace saw a makeover featuring — in addition to the Celtics green parquet floor section — green walls, a Celtics locker, a 2008 championship banner, and a Celtics wall graphic.

“I was just in awe. It was amazing,” Jace said.

The makeover works well with the collection of Celtics gear Jace already had. The locker is perfect for his collection of Celtics jerseys.

The project is a partnership between the Celtics and Bona, the Swedish company which provides products for wood floor maintenance and renovation. The makeover required multiple visits to Swansea over the last three-and-a-half weeks. The first visit was to shoot the “before” video. Next came the painting. Then the flooring. Then the graphics. Most recently the final touches.

Jace, his mom reported, showed amazing restraint, refusing to even sneak a peak during the makeover. He slept in her room or the living room. He was determined to make the unveiling an unadulterated surprise. Caution tape was stretched across the doorway during the work and Jace, she said, did not violate it.

Tabitha, by contrast, was checking out the progress all along.

“I don’t have the willpower he has,” she said.

Tabitha, who watches Celtics’ games with Jace, had the choice of which room in the house would get the makeover. “It was a no brainer,” she said.

Of the winning video, Tabitha had originally wanted to post it on Facebook. Jace did not want her to do that. But when she mentioned an Instagram post for the Celtics contest, her son gave her the green light.

“I’ve never won anything in my life,” she said, "but this is a good one.”
