I hired Dingeman Concrete to put in a patio. What I got was a ramp...they didn't excavate the top part of the area but instead built it up and I now have a steep ramp from my deck to my shed. I wanted a patio that I could put a table on but can't use the RAMP the way it is and am currently getting quotes to have everything ripped out and redone with proper excavation. Total waste of money, I emailed them and have never heard anything but they certainly cashed my check. On their quote it says they will put a lien on your property if you don't pay which in hindsight tells me that they have done poor workmanship in the past. I would never recommend this company for any concrete work and am currently filing a complaint with the Iowa Attorney General's office. Tried to file with the BBB but they are not members which again, in hindsight tells me that I should not have chosen this company.
