Chimney Liner Installation
The liner is the chimney's inner shield — containing heat and gases and protecting the masonry. We install it right.
The liner is the flue's inner surface — the barrier that contains heat and combustion gases and keeps them from reaching the surrounding masonry and your home's framing. A sound liner is fundamental to a safe chimney; a cracked, missing, or improperly sized one is a genuine hazard.
Frank & Sons installs chimney liners — most commonly stainless steel — sized and specified for your appliance and fuel. Whether you're relining an older chimney, correcting an unlined flue, or installing a liner for a new appliance, correct sizing and installation are everything.
When you need a liner installed
- An older chimney with no liner or a deteriorated clay-tile liner.
- Installing a new stove, insert, or furnace that needs proper venting.
- A liner damaged by a chimney fire or long-term moisture.
- Switching fuels or appliances with different venting needs.
- An inspection revealed cracked or gapped flue tiles.
How we install liners
We size the liner to the appliance and fuel — an oversized liner drafts poorly and an undersized one is unsafe. Stainless steel liners suit most wood, gas, and oil applications and, properly installed and insulated, deliver reliable draft and long service life.
Installation includes running the liner the full length of the flue, insulating where appropriate, and connecting it correctly at the appliance and the top, finished with a proper cap. The result is a flue that vents safely and protects both the masonry and your home.
Why it matters in Greater Pittsburgh
Many older Pittsburgh chimneys were built with clay-tile liners — or no liner at all — that no longer meet the needs of modern appliances. Relining with stainless steel is one of the most common upgrades we perform when homeowners add an insert or high-efficiency appliance.

Frequently Asked Questions
An inspection tells you definitively. Warning signs include an unlined older chimney, cracked clay tiles, or installing a new appliance. We scan the flue with a camera to confirm.
Stainless steel liners are versatile and durable, suiting most wood, gas, and oil appliances. The right choice depends on your specific appliance and fuel, which we size for you.
A liner that's too large drafts poorly; one that's too small is unsafe. Correct sizing to the appliance is essential for safe, efficient venting.
