I was very happy until I began to have problems covered under warranty, as confirmed by Hemma. At the end of my driveway, Hemma tore up part of the asphalt street. They patched the asphalt but it did not hold up. It took MANY telephone calls but the job was not repaired for over 6 months. It has not held up and I dread starting the process again to have them repair it. It was not really the amount of time it took for the repairs to be made -- what was so frustrating was that the office contact, Barbara Cogen, stopped answering my phone calls; I was always transferred over to her voicemail. And, of course, she stopped returning my calls. Finally one day after I left ANOTHER message for her, I immediately called Ms. Cogen using a friend's telephone and she answered the phone -- so I was quite convinced that she was avoiding me. Also, shortly after the driveway and sidewalk were done, the on-site project manager, Frank Diaz, stopped by my house. He took note of several insignificant items that were to be corrected but no one ever contacted me about them and I never complained about this. I have recommended Hemma to neighbors and Hemma was given a job by two neighbors with adjoining driveways. The job cost roughly $25,000. They have had issues and, to my knowledge, have not gotten satisfactory answers or correction of their problems. No, I cannot use Hemma again, despite the fact that they did a very good job initially. Their customer service stinks and the warranty is barely worth the paper it is written on. Not to mention that I so regret having recommended them to anyone.
