Cast-In-Place Liner Restoration (GoldenFlue / Supaflu-Style)

A cementitious cast-in-place system with form or bladder and mortar that rebuilds a deteriorated flue in place, restoring a smooth, insulated, code-rated passage inside the existing masonry. It is the lasting answer for a historic or oversized flue where a stainless liner simply cannot be sized in: done right it is permanent and it strengthens the chimney. We never sell it as materials, because this one lives or dies entirely on the install.

Stainless Steel Flexible Liner Kit — Full (316Ti / 304)

A complete 316Ti or 304 stainless flex liner with cap, top plate, tee, connector, and clamps to reline a masonry flue for wood, gas, or oil. Alloy is the whole conversation here: 316Ti for wood and high heat, 304 where the fuel allows, and we will tell you which your appliance requires rather than push the lighter grade to shave a dollar. A Level-2 camera inspection comes first, then we size the liner to the flue and the appliance and insulate it. Supply-and-install only, because a flex liner kinked or under-clamped on a DIY pull is a flue fire waiting to happen.

Liner Insulation Blanket Wrap Kit (¼" / ½", UL 1777)

A ceramic and mineral blanket with mesh and bands to wrap a stainless liner for clearance and draft per UL 1777. We treat this insulation as standard rather than optional: an insulated liner drafts hotter, keeps creosote down, and earns the clearance reduction the listing allows. Skipping it to save a little is the false economy that brings you back with a draft complaint.

Refractory Firebox Panel Set (Prefab / Masonry Replacement)

Pre-cast refractory panels, OEM-matched for factory-built fireboxes, that replace cracked firebox walls and floor and restore the firebox's rating. Cracked refractory is a genuine safety item, not a cosmetic one: once the panel cracks through, the steel shell behind it is exposed to the fire. We match the OEM panel to your firebox model, because a generic panel that is merely close voids the listing.
