Warning: a 3 foot crack in a flue liner almost ruined my week
Got a call for a standard cleaning in a 1920s house here in town. Everything seemed fine until I ran the camera up and saw a huge vertical crack, about 3 feet long, in the clay liner. The homeowner had no idea. I had to stop the cleaning right there, explain the carbon monoxide risk, and give them a quote for a full liner replacement. It was a tough conversation because the repair cost is over $2,000. What makes you guys decide when a crack is bad enough to stop work and push for a full fix instead of just noting it on the report?
