(KMOV) -- Be careful if someone comes to your door and offers to pave your driveway.
MoDOT is warning of some paving scams.
In this scam, a person comes to the door, saying they have extra asphalt from a previous job and then offers a cheap price.
The problem is that the workmanship is bad and prices end up higher than initially expected.
Officials say you should ask for references, get multiple bids and never sign a contract that has blank portions.
