Answered knowing full well that this call was a scam.

A "licensed contractor" is the area would like to stop by and give you a free estimate.

When I asked for his CA State Contractors License #...he hung up.  HOW RUDE!!!   :)

Have blocked their future calls.

Buy a call-blocking phone.  

Uniden and Panasonic make wonderful call blocking phones and they're inexpensive.  They also come with at least one wireless handset.  Very handy!!!

These phones also block “Out of Area” and “Private” calls.
