Shoutout to the old guy in Burlington who told me to use a mirror on a stick
I mean, I thought it was a dumb gimmick for years, like why not just use a camera? But last month I had a real bad creosote buildup in a tricky offset flue on a house in Essex Junction. My camera died, so I dug out this cheap mirror on a pole I got at a yard sale. Idk, seeing the actual reflection, not a screen, let me spot a hairline crack in the clay liner I would've totally missed. Has anyone else had a simple tool surprise them like that?
