Chimney Liner Replacement in Colorado

About This Service
Existing liners fail too — clay tiles crack with age and thermal shock, aluminum liners corrode on gas service, and undersized past installs cause chronic draft and creosote problems. Liner replacement removes or bypasses the failed system and installs one engineered for the appliance it serves.
We diagnose on camera first, because 'replace the liner' should be a conclusion, not a sales pitch. When replacement is warranted, we install lifetime-warranted stainless, sized and insulated correctly, and show you the before-and-after footage.
Signs You Need Chimney Liner Replacement
- Existing liner visibly cracked, gapped, or collapsed on camera
- Aluminum gas liner showing corrosion or separation
- Chronic draft problems traced to a wrong-sized liner
- Creosote condensing heavily due to an oversized cold flue
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
My clay tiles are only cracked in one spot — full replacement?
Sometimes localized tile damage can be addressed, but tiles rarely crack alone; thermal events and settling usually affect multiple joints. The camera footage tells the story, and we recommend based on what it shows.
What kills aluminum liners?
Condensate. Gas exhaust is water-heavy and mildly acidic, and in a cool Colorado flue it condenses and eats aluminum within 10–15 years. Stainless replacement ends that cycle.
