Spam call from "Justin" who claims to be a stone mason (using the number 940-220-6500 he claims to be a landscaper); calls repeatedly says he is in the neighborhood (really, how would he get my phone number from the front of my house?)

Same - except claimed to be "Del" or "Dale" - claimed he was driving around and noticed I had a "telltale signs" of a foundation problem and want to give me and my friends a foundation evaluation.  Scare tactic scam.  CallerID comes up as GrandPrairie, probably a cell number.

Got a similar call... "working in the neighborhood"

Same as above. Saying foundation issues. If I wanted foundation evaluation I would call a reputable company myself and not wait for any Tom, Dick or Harry to contact me.
