A change in how I check for hidden cracks in flue tiles
For a long time, I just used a bright flashlight and looked straight up. About eight months ago on a job in Tacoma, I missed a hairline crack in the back of a clay liner that a home inspector later found. Now I always use a mirror on an extension pole, or a cheap inspection camera from Harbor Freight, to slowly turn and check all four sides of every tile. The old way just doesn't catch everything, especially in older chimneys. Has anyone else switched up their inspection method after a close call?
