WARNING!!!!! DO NOT USE THIS CONCRETE COMPANY AND MAKE SURE YOUR GC DOES NOT HIRE THIS COMPANY!!!!! We hired a GC to do our driveway at the end of October after many homes in our immediate Greenwood Village neighborhood had the same GC do their driveways. We were the last home to have its driveway poured before temperatures plummeted last October 2025. We paid the GC for the job in full at the time it was done, only to receive a NOTICE OF LIEN on our home in January of 2026. We could not understand what was happening at the time. Then we found out that all the homes (about 8in total) that had their concrete poured before us were also having liens put on them. We have since learned from a neighbor that Justin Buxbaum, one of the owners of On-Demand Concrete, had actually admitted, that by October (when our concrete job was ordered), they had not been paid by the GC for several jobs, which we did not know or have any way of knowing, however, On- Demand Concrete chose to deliver the batch to our job anyway. Their poor business judgment is now our nightmare. We have proven that we paid in full at the time of the delivery. IF YOU DON'T WANT TO HAVE A LIEN ON YOUR PROPERTY, DO NOT HIRE OR LET YOUR GC HIRE ON-DEMAND CONCRETE!!!!!!! They made a very poor decision to keep delivering concrete for a GC who wasn't paying, and now they want us to pay for it. read more
