The switch from clay to metal liners in old houses around here
When I started twenty years back, almost every job in our historic district was fixing cracked clay tile liners. Now, I'd say eight out of ten of those same repairs are full metal liner inserts. The big shift came around 2010 when the local building code started really pushing for listed liner systems in pre-1940 homes. It changed the whole job; less messy mortar work, but you need to be real careful measuring the old flue. Anyone else notice their repair jobs leaning this way now?

My last five liner jobs in the old Victorian neighborhood were all stainless steel inserts. The code change really did flip the whole trade on its head. It's a cleaner fix, but man, getting those old flue measurements wrong is a costly mistake.

Yeah, those old flues are never square. I always take three measurements, top, middle, and bottom, and go with the smallest one. Even then, I'll add an extra half-inch clearance on the order. It's cheaper to pack a little extra insulation than to eat the cost of a liner that won't drop.
