Based on real stories that have happened to friends and neighbors, make sure your contractor comes recommended and with the following qualifications:
1- Make sure your contractor knows what a tape measure is and that it should be used before cutting countertops.
2- Make sure your contractor knows that cabinets must be installed as well as assembled. (Happened to an older couple who couldn’t do it themselves)
3- Make sure your contractor is capable of hooking up your sink and gas line if necessary. If he’s really just a handyman who can install IKEA cabinets this isn’t a given.
