After running into a problem with the company that the dishwasher was purchased, from, i needed to have the unit installed same day and quickly as guests were over for a wedding. I called roto rooter and they sent somebody out withing the hour and removed the old dishwasher and installed the new one. Although i am completely satisfied with the work that was completed, the cost was a lot more than i had expected. Most companies were charging approximately $150, but Roto Rooter charged by the hour and the project took three hours. I was happy that i was able to have my dishwaher installed same day and quickly, but it was so much more expensive than anywhere else.
