David Martinez seemed like a professional courteous man at first, but in the end was unwilling to stand by his work. Poor workmanship was the cause of crooked, wavy lines on the edges of my sidewalk and patio. When David was unable/unwilling to correct this I held back a small percentage of the balance owed. Then things got worse. The surface of the driveway began to severely flake and crack. When I contacted David he refused to even come back to look at it. He said it was "Bad Karma" for me holding back money (very unprofessional statement).
I tried to resolve this with a lawsuit, but have not been able to locate his agent to serve papers.
I would not recommend David or Denver Pro Concrete for any work read more
