Chimney Liner Installation in Colorado
Chimney Liner Installation by Donovan Chimney & Fireplace: honest diagnosis, written pricing, and quality work across the Colorado Front Range. Family-owned since 1998 · Licensed & insured · Open 24/7.
About This Service
Liner installation puts a code-compliant flue inside a chimney that never had one, or adds the correctly sized liner a new appliance requires. Thousands of older Colorado chimneys — especially pre-war homes in Denver, Pueblo, and the mountain towns — are bare brick inside, which no modern code or insurer accepts.
We install insulated stainless systems sized to the connected appliance, from wood stoves to furnaces to water heaters. Insulation matters at altitude: it keeps flue gases warm enough to draft strongly and rise clear, which is a genuine performance issue above 5,000 feet.
Signs You Need Chimney Liner Installation
- An unlined flue confirmed by inspection
- Installing a wood stove, insert, or new furnace on an old flue
- Home insurance or a real-estate inspection flagged the flue
- Converting a fireplace between fuels
The Relining Process
Camera scan and measurements confirm liner condition, flue dimensions, and offsets.
The liner system is sized to the connected appliance — this is where performance is decided.
Insulated stainless liner installed full-length, connected, and terminated correctly.
Final camera pass documents the finished system for your records and insurer.
Why It Matters for Safety
The liner is the barrier between 1,000-degree flue events and your home's framing, and the seal that keeps carbon monoxide in the flue where it belongs. It's the single most safety-critical component in the system — which is why liner findings lead our inspection reports.
Maintenance Tips From Our Technicians
- Have liners camera-checked after any suspected chimney fire, full stop.
- Annual sweeping protects liners — corrosive creosote sitting on tile all summer does damage.
- Burning dry wood keeps flue temperatures in the range liners are designed for.
- Keep liner documentation; lifetime warranties transfer and help home sales.

Frequently Asked Questions
Why does the liner need insulation?
Insulation keeps exhaust hot through the full flue run, which improves draft, reduces creosote condensation on wood systems, and prevents acidic condensate on gas systems. At Colorado altitudes, where thinner air already weakens draft, it makes a measurable difference.
Can any chimney be lined?
Nearly all. Offsets and tight flues sometimes call for specific liner profiles or minor masonry access work, which is exactly why we camera-scan and measure before quoting.
