First of all, they appeared unannounced a week early before the scheduled appointment and inconvenienced my family since we could get no cars out of the garage while they worked. They haphazardly rushed through the job and left at noon. They assured me that this material was like the last job (from another contractor) which was very good and lasted a number of years. The paving washed away within less than a year...very disappointing and so I had to contract with another company to pave the driveway.
