I have one but they don't always work. I had a contracted sales person from Verizon show up at the door and BANG on it, not just knock or use the doorbell. I opened the door and said 'Don't you see the sign?' and he says 'Oh, i haven't been to your door yet.'sjfcontrol wrote:If you're referring to "No Soliciting" signs, they DO work. I understand that a salesman ignoring that sign is trespassing. I've seen them come up to the door, see the sign, and turn around and leave.rthillusa wrote:and signs do not work, even if printed in Spanish and English.
BUT, I wouldn't expect the sign to turn away criminals -- Perhaps we need a "No Criminals" sign, too.
I respond, 'Then who the heck just pounded on my door? I suggest you leave my property'. 'Well, don't you want Fios?' I said, 'Let me see a copy of your permit to solicit from the city.' He says 'I need a permit?' I told him, 'Yes, you have to have a permit, you need to leave and you will be contacted by the police shortly.' He got mouthy and turned to leave and I closed the door and called the non-emergency line of the police. I also was able to follow up with Verizon and spoke with the manager over the contract door-to door sales team. She advised she has already heard about the incident, and that the 'boss' over that company had released the guy as he did have a copy of the permit and got mouthy with the contract company manager when asked why he didn't show it to me. 
Bottom line, while it does help, even if the sign is there, they may or may not read it or abide to it. I still get door hangers from lawn companies and other sales groups. I usually call and threaten to sue them if they leave anything else. That gets their attention.
