Big shout out to Floyd's crew coming through in a desperate situation here in Cedar Rapids, IA. We had an unbelievable storm come through and demolish our city. We were without power for over a week and when our situation looked bleek they came in and flat out got s*** done!

I reached out to them for a quote on a project. The VP (Jamie) declined the work because it wasn't a good fit for them. He then recommended two other contractors to call AND offered some suggestions to make the project a success. I'm grateful for contractors like this...just trying to make sure of a successful project, whether its their project or not.

They broke my car window and won't contact me back to take care of it. They have safety on their website, however I get the feeling that they would have prefered that the rock had hit a motorcycle so they would have eliminated the witness. Companies with trucks on the road should be far more responsible.
