About Us
Three principles. One promise.
Quality craftsmanship, transparent communication, and on-time delivery — built into every project we take on.
Our story
A North Bergen family business.
Established in 2021, 3 Diamond Group brings over 25 years of hands-on construction experience to every project. The company was built on a simple idea: treat every home like it was our own. From small bathroom updates to full home additions, we bring the same craftsmanship, communication, and care to every job.
Today we're a trusted name across Northern New Jersey — fully licensed, insured, and consistently rated among the area's top contractors on BuildZoom.
Our values
Why three diamonds.
Craftsmanship
Every cut, every joint, every finish — done right the first time.
Communication
You'll know what's happening on your project, every single day.
Commitment
We stand behind our work with a workmanship warranty.
