Chimney Flue Relining with Thermocrete

A sound masonry flue with cracks or gaps can be relined in place. Thermocrete forms a smooth, seamless liner inside the existing flue.

Chimney relining restores a masonry flue without tearing it out. When a flue has cracks or gaps, or has failed an inspection, but the masonry is still sound, Eco Grizzly relines it with Thermocrete. It forms a smooth, seamless liner inside the existing flue, and our own trained technicians install it.

Flue Relining

Warranty and Recent Work

Thermocrete carries a lifetime manufacturer warranty. Our own trained technicians install it, never subcontractors. Recent Thermocrete relines include Beverly Hills in October 2026 and South Pasadena in September 2026.

When Thermocrete Is the Right Reline

Thermocrete fits a sound masonry flue that has cracks or gaps, or has failed an inspection. It suits wood-burning fireplaces, and it works in odd-shaped or oversized flues.

When Stainless Steel Is the Better Fit

If the flue is too damaged to reline in place, or it serves a gas appliance or an insert, a stainless steel liner is the right repair. We handle that through chimney flue liner installation.

Camera Inspection First

Every reline starts with a camera inspection of the flue. It shows whether the flue suits Thermocrete, needs a stainless steel liner, or only needs its joints sealed. Cracked tiles and joint sealing are covered on our chimney flue repair page.

Flue Relining FAQs


Common questions answered by our certified technicians.

Thermocrete fits a sound masonry flue that has cracks or gaps or has failed an inspection, wood-burning fireplaces, and odd-shaped or oversized flues. Stainless steel fits a flue that is too damaged, and gas appliances and inserts. We inspect the flue with a camera first and tell you which one it needs.
Thermocrete carries a lifetime manufacturer warranty and is installed by our own trained technicians.
Yes. Thermocrete suits wood-burning fireplaces, as long as the masonry flue is sound. Gas appliances and inserts get a stainless steel liner instead.
It depends on the flue. Chimney height, the flue's size and shape, and what the camera finds all change the scope, so we inspect first and quote the real job rather than a guess.
