Onyx was great with a basement development of mine. They’re timely and communicate well. They are reliable and very honest working. And their painter is amazing! The basement looks so good. 10/10 would work with again!

Onyx Construction did a fabulous job with our basement. Andreas was there every step of the way ensuring that the contractors kept on schedule and worked so hard himself. We can't say enough about how much effort he put in and we are very happy with the results.

Andreas was exceptional in creating what I envisioned into reality. He detailed the steps that he will take from start to finish and kept me in the loop throughout the entire process. Thank you Andreas!

I’m extremely impressed with Andreas and his team for developing my basement! They were professional, attentive, and delivered high-quality work on time. The transformation is exactly what I envisioned, and I couldn’t be happier with the final result. Highly recommend them.

Andreas and his team builds for us an amazing basement exactly as my son wanted with beautiful finishing he was following up with us with every small detail which was amazing and cleaning up after every work at the end he gives a beautiful basement and his work was unique, thank you so much Andreas and to all your support your a man that count on always I am so proud of you .

I hired Onyx for my basement development. Andreas & Sikander met all my needs & standards. I’m really satisfied with the finishes especially with the bathroom. I would highly recommend them. I will hire them in the future again. Thank you guys
