I'd give this zero stars if I could. They don't answer their office phone. You call their "contact" cell-phone line and some guy answers it, but never tells you the name of his business or his own name.
You ask to make an appointment to get an estimate, and he just gives you a price. He's not interested in either meeting with you or seeing the proposed job.
If you decide to go with this company, he gives you his office e-mail address and asks you to send an e-mail to that address with your address and what kind of job you want.
You do that and you never hear back. So after a while, you send another e-mail asking if they got the first one (because you happened to notice that their website has been hacked).
You get a response to your second e-mail telling you they'll start tomorrow. No capitalization, no punctuation, just "tomorrow thanks"
A crew shows up the following day and without even letting you know they're there, starts tearing up things. Things you didn't want torn up!! Since you just happened to be home in the middle of the day, you go rushing outside to tell them to stop! You explain what you actually wanted them to do, and suggest to the guy that seems to be the head of the crew that maybe, in future, his boss should actually talk to customers first. He gives you a "thumbs up" sign and says, "Good idea."
You go back inside, grateful as all get-out that you happened to be home and looking out the window when they showed up.
Another crew comes back a few days later with a cement truck. They finish pouring your project (including fixing what they tore up that you didn't want torn up) and then the cement truck turns around and washes out the chute on your next-door neighbor's front lawn.
And that's the way things stand right now. I'll edit/update if further difficulties crop up with the cement drying and/or billing/payment.
Almost three months later, you receive another one line e-mail telling you to send a check for $XXX made out to him personally. No actual invoice.
Two DAYS after that, you get a threatening text telling you that he "still owns" that concrete and will come rip it up if you don't pay.
