Lady in Amarillo handed me a handwritten map of her attic and it changed how I do walkthroughs
Last month I was out in Amarillo doing a panel swap on a house built in 1952, and the homeowner, Ms. Delgado, pulled out a folded piece of notebook paper before I even got my ladder off the truck. She had drawn every wall, the two attic access points, and marked where her late husband had run phone lines back in the 80s with a little X. I asked why she kept it, and she said the last installer spent 40 minutes hunting for the crawlspace hatch and put a boot through her ceiling drywall. Now I ask every customer to sketch their layout before I start, and it has saved me from guessing wrong on at least six jobs since. Anybody here doing something like this, or do you just trust your stud finder and hope for the best?
Asking for a sketch is fine but I wouldn't make it a rule, most folks can't draw worth a darn and their "map" just sends you looking in the wrong spot. I still poke around with the stud finder first and treat whatever they hand me as a hint, not gospel.
