Junk King in Reno/Sparks is very professional - they call roughly 20 minutes before they are due to arrive and get the job done quickly. I have used them to remove junk, trash, and recyclables twice now and highly recommend them.
I had used Junk King in the past so I was not surprised that they showed up on time and quoted a most reasonable price for the materials I wanted hauled away. They worked quickly and were very courteous. There is no reason to consider using any other company than Junk King.
