Its not uncommon to have a repair person knock on your door when they're expected but when one stops by unannounced, a homeowner's guard should go up.
The door-to-door approach is becoming more common for businesses and the Zanesville Police Department wants homeowners to always be wary of those they let in their home.
"I would caution people not to let people inside their residences. Often times what will happen more than one person will enter the residence they'll distract the homeowner then a second person or possibly a third person could go through the home and see whatever valuables may be available that they could steal," said Detective Sergeant Harry Taylor of the Zanesville Police Department.
There are people that do work for reputable companies and perform legitimate services but most homeowners don't always have a way of knowing for sure who they are dealing with.
"The main thing is you don't want to let someone inside your home you don't know. If you're concerned, if someone comes to your door or see them at a neighbors house and you don't think that what is going on is right, call the police," said Detective Taylor.
Detective Taylor says to watch for red flags when dealing with door-to-door salespeople, if they are not wearing an official uniform or driving a company vehicle, don't trust them.
