Flexible Chimney Liner Installation in Alamo Heights, TX

This one comes down purely to the liner type, and geometry drives it. Flexible corrugated stainless is for flues with offsets, doglegs, or elbows, or tight and out-of-round clay tile where a rigid liner simply will not feed through, and for running a liner down to the collar of a gas or wood insert around an offset. On a straight, accessible flue, rigid gives you smoother walls and slightly better draft, so flexible is not the default; the bends in your chimney settle it.

It is a subset of it. Relining is the broad decision to replace a flue's liner, and a flexible liner is just one of the materials that decision can land on, the bendable kind you would choose when the flue is crooked or you are venting an insert. Reline a straight flue and it might take rigid or cast-in-place instead. If your chimney has offsets or you are venting an appliance, flexible is usually the answer, and that specific option is what this page covers.

Often, yes, and more so than with rigid, because the corrugation runs a bit cooler and drags on the draft. On wood-burning and many other solid-fuel installs, insulation is required both to meet the listed clearance to combustibles and to hold flue temperatures high enough for good draft and less creosote. It does add cost per foot and eats into flue width, so it is not automatic; the appliance listing and the clearance to nearby framing decide it.

That is precisely what it is listed to do. The corrugated wall bends within the manufacturer's listed radius, so we ease it around offsets and elbows instead of forcing it, since a kinked or torn liner no longer seals. Every bend gets camera-mapped up front, an oval profile goes in where a round one will not clear a tight throat, and positive top-plate and collar connectors get locked down so the whole bent run stays gas-tight end to end.

A properly installed liner in the right grade for your fuel commonly runs 15-20 years or more, often with a manufacturer warranty that is tied to annual sweeping and inspection. Because the flexible corrugation carries more surface area than a smooth rigid wall, burning unseasoned wood, trash, or the wrong fuel for the grade eats it up early and can void that warranty.

That's the whole design of it. Older homes interconnect in ways separate contractors miss — the chase that carries your original flue often carries duct runs and wiring too, and an uninsulated attic changes how the entire house breathes. We inspect chimney, ducts, dryer vent, and insulation in one pass and write it up as one prioritized report, so you're not reconciling four different opinions.

Maybe — many pre-war flues here are unlined or have cracked clay tiles, and you can't tell from the hearth. A camera inspection settles it in about twenty minutes. If it's sound, we document that and sweep it. If it needs a liner, we price it plainly and tell you what's safe in the meantime, which is sometimes nothing until it's fixed.

Inspection first, always — it sets the sequence. Typically: chimney safety items before burn season, attic air-sealing and insulation in spring or summer when it pairs naturally with duct sealing, and the dryer vent the same day as everything else since it takes the least time. Masonry repairs cure best in warm, dry months, so we slot those accordingly.
