Flexible Chimney Liner Installation in San Marcos, TX

Geometry decides this one, nothing else. Flexible corrugated stainless earns its place in flues with offsets, doglegs, elbows, or tight or out-of-round clay tile, anywhere a rigid liner physically cannot be fed through, and it is also how a liner gets dropped to a gas or wood insert's collar around the offset. In a straight, accessible flue, rigid wins on its smoother walls and slightly better draft. So we never default to flexible; the bends in your chimney make the call.

Think of it as one branch of the same decision. Relining is the broad call to replace a flue's liner; flexible-liner installation is one of the materials that call can land on, the bendable option chosen when the flue runs crooked or you are venting an insert. A reline of a straight flue might land on rigid or cast-in-place instead. Chimneys with offsets, or any appliance being vented, usually point to flexible, and this page covers exactly that option.

Usually it should be, and more than a rigid liner needs — the corrugated wall runs a touch cooler and drags on the draft. On wood-burning and most solid-fuel setups, insulation is what lets the run meet its listed clearance to combustibles and hold flue temperatures high enough to draft well and lay down less creosote. It does add cost per foot and eats into flue width, so we never call for it by default; the appliance listing and the clearance to the framing nearby are what settle it.

That is precisely what a flexible liner is listed to do. Its corrugated wall flexes within the maker's listed bend radius, so we coax it around offsets and elbows instead of forcing it, since a kinked or torn liner no longer seals. We camera-map every bend before anything goes in, drop to an oval profile where a round one will not clear a tight throat, and lock positive top-plate and collar connectors so the whole bent run stays gas-tight end to end.

Sized to the right grade for the fuel and installed properly, a stainless liner routinely gives 15-20 years and often much longer, usually under a manufacturer warranty that holds only if you keep up annual sweeping and inspection. The flexible corrugation carries more surface area than a smooth rigid wall, so burning unseasoned wood, trash, or a fuel the grade was never rated for eats it away early and can void that warranty.

More readily than a dense stone — it is porous and soot marks it. Whether that is patina or damage is a decision to make deliberately rather than discover.

If you want it to stay pale, yes, with a breathable stone sealer. If you want it to age, leave it — both are legitimate and they lead to very different rooms in ten years.

A firebrick or metal reveal at the immediate opening, where soot concentrates. It keeps the marking away from the face you chose the stone for.
