To begin with the work was done about a year ago, towards the end of the home renovation tax credit so every trade was super busy. I needed to have a portion of my concrete mutual drive replaced so I called Otto. It took two calls to get a quote and they quoted on exactly what I asked for. I obtained a quote from another contractor who insisted I be there for the quote. His price was almost double Otto's so despite what other reviewers have said I found Otto's pricing to be good. I had planned to leave a portion of the driveway intact and the other contractor said it would cost as much to work around as to replace so his consultation was helpful I wished I had listened to him or Otto had made the same suggestion. I accepted Otto's bid and was told my work was scheduled for a few months out. Almost a week later I got a call that they could start today and then a call a couple hours later saying no but tomorrow. They didn't show the next day and they didn't call but it was a rainy day. They did show up on the 3rd day and the work was completed in 2 days. The work is solid, it's not overly pretty, it's higher than the old driveway in spots and in a couple of spots they built little concrete ramps between the old concrete and the new. I fear those ramps will crack, but they haven't yet. I would definately use him again but would ensure I was around for the quote to consult more.
