What do people have to say about us?

Rose F.
Their team did a fantastic job on replacing the door between my Home and the garage. It had to be “fire rated” quality. They knew all the specs and building codes to ensure the job was done right. Their selection of the door style and all supporting details were outstanding. Their staff has great customer service orientation. When I asked for a recheck of closure, the contractor was out the same day. I am highly satisfied and recommend Cobex for high quality results.

Bottom line, these gentlemen are top notch! I so appreciate their quick response, punctuality, easy to understand communication, thoroughness of plan, a fair estimate, attention to detail, and the work done to perfection. I will not hesitate to call them for future projects.

I really am happy my family hired Cobex Construction. Surgey and his crew were amazing. We had issues with our insurance not being helpful about replacing our new roof and This company helped in every way and went above and beyond. My parents home looks amazing and we have future plans of hiring them in the future for any of our construction needs and highly recommend. Thanks Again Surgey and everyone at Cobex Construction Group.
