What Our Clients
Say About Us.

They hit every milestone, communicated proactively, and delivered exactly what they promised. The lot looks great and held up perfectly through the first Texas summer.

They found $180K in savings we didn't know existed, delivered two weeks early, and kept us informed every step of the way. That's the kind of contractor you keep calling back.

We've done build-outs with five different contractors across our locations. Onyx & Iron is the only one that has ever hit our opening date. They're the only call we make now.

Justin answered every question I had — even the ones I was embarrassed to ask. I always knew exactly where my money was going. No surprises, no change orders. Just results.

I've worked with a lot of concrete contractors over the years. Onyx & Iron is the only one I've found that actually does the subgrade prep right. My driveway has been perfect for 3 years.

The JV partnership model was exactly what I needed. I'm good in the field but terrible at the business side. They handle the front end, I handle the work, and we both make more money.
