Welcome to Sergio's Construction, here to assist you with all of your remodeling needs. I have done consistent service all of my life. You will not be making the wrong choice when choosing, Sergio's Construction. Give us a call today!
"My request was for a simple curb core. I paid a $106.00 deposit and they sent someone who didn't know what he was doing and he broke the concrete around the hole (pic attached). I called and the owner came out two days later and put on a patch. I was concerned that it wasn't going to last so refused to pay until, at least, the patch had dried. Two days later, I moved the pipe he put through the hole (it was sticking out in the gutter) and the patch fell out. Pictures attached. I called and didn't hear back for 24 hours so have now hired someone else to repair the damage. I want my $106 deposit back. He destroyed my curb and now I have to pay MUCH more to repair it. At this point I don't want him to do anything further. If we end up in court I'm going to ask him to pay for the repair."
