UL Listed Liners

Chimney Liner Installation In
Allen, TX

The chimney liner is the inner wall of your flue — it contains heat, combustion gases, and sparks and directs them safely out of your home. When a clay liner cracks or an older chimney has no liner at all, a stainless steel liner insert is the safest and most cost-effective solution. We install UL-listed liners for wood and gas fireplaces across Allen and Collin County. Call (972) 521-7225.

Stainless Steel Liner Install — Starting at $1,500

Why It Matters

Why Your Chimney Needs a Sound Liner

The liner serves three critical functions: it protects the house framing from heat transfer, it contains combustion gases (including carbon monoxide) inside the flue, and it protects the masonry from the corrosive byproducts of combustion. Without a liner — or with a cracked one — all three functions fail.
Most Allen homes built in the 1980s–2000s have clay tile liners. Clay works well when intact, but once a tile cracks, the crack exposes the surrounding mortar and brick to direct heat and combustion gases. A cracked clay liner cannot be repaired — the entire flue needs to be relined.

A Level 2 video inspection is the only way to know the true condition of your liner. Our HD camera scan shows every crack, gap, and deterioration point in the flue. If relining is needed, we install UL-listed stainless steel liners with a lifetime warranty.

When You Need a Liner

Signs Your Liner Is Damaged

A cracked liner is a serious safety hazard. Carbon monoxide can leak through cracks into living spaces. If your liner is compromised, stop using the fireplace and schedule a chimney inspection immediately.

FAQs

Chimney Liner Questions

How much does a chimney liner cost?

Stainless steel flex liner (most common): $1,500–$3,500 installed. Rigid stainless: $1,800–$4,000. Cast-in-place: $3,000–$7,000. Price depends on flue length, diameter, and whether insulation is required. We provide exact quotes after a video inspection of your flue.

Stainless steel liner installation takes 1 day for most Allen homes. Cast-in-place can take 2 days. We schedule the video inspection and installation on separate days so you get a full assessment before committing to the work.

Minor surface cracks can sometimes be patched with HeatShield, a ceramic sealant applied from inside the flue. But if the clay tiles have shifted, separated, or have structural cracks, the only safe solution is relining with stainless steel. We determine this during the Level 2 inspection.

Yes. A properly sized stainless steel liner often improves draft because it’s smooth (less friction than rough clay tiles) and properly sized for your appliance. Many homeowners notice the fireplace draws better, smokes less, and burns more efficiently after relining.
