About Us

Original (1).png

We are a young, energetic company founded in 2022. Our mission is to earn repeat business from our clients who trust how we solve problems on the fly, meet and exceed expectations and perform better than our competition.

Jack DesMarais, Owner

Jack was raised in construction, helping his dad and brothers in various trades including drywall, paint, demolition, tile, roofing and carpentry. With a passion for finance and performance vehicles, Jack’s personality is perfect for running his own company. Jack is organized, driven, enthusiastic and holds high standards for himself. He prides himself on being authentic in all of his business relationships and continually educating himself on the topics of investing and entrepreneurship. If you really want to know who you’re dealing with, ask him about the night he and his crew worked until 5 a.m. in pouring rain to offload a shipment of hundreds of boxes of yet-to-be-assembled furniture. “A few of my guys said it was the worst day of their lives,” he laughs. “It makes for a great memory, though. And we got the job done!”
