Craftsmanship built on a handshake
Welcome to ONYX. Founded by Rhett Mattson as an owner-operated renovation and carpentry company, we've grown through word-of-mouth and repeat clients who value careful craftsmanship, clear communication, and attention to detail.
“ONYX was built around a simple principle: do the work properly and stand behind it.”
From solo trade to trusted name in North New Jersey
What began as a solo trade has grown through word-of-mouth and repeat clients who value careful craftsmanship, clear communication, and attention to detail. Every project is approached with the mindset that the work should be executed with a commitment to excellence.
ONYX Home Solutions remains owner-operated by design. When you hire us, you work directly with the craftsman leading your project—not a sales team or rotating crew. That personal accountability is what sets the ONYX experience apart.
Built on trust, not volume
We measure success by the homes we transform and the relationships we keep—not by how many jobs we can rush through. Quality work speaks for itself, and our clients refer us because they know we stand behind every detail.
Commitment to excellence
Whether it's custom carpentry or a full interior remodel, the same Design–Finish standard applies: thoughtful planning, quality materials, and craftsmanship that holds up over time.
Owner-led craftsmanship from first conversation to final walkthrough
