About This Service
The liner is your chimney's inner conduit — the part that actually contains heat, flame, and exhaust gases. When clay tiles crack, joints gap, or an old flue was never lined at all, relining restores that containment, usually with a continuous stainless steel liner that has no joints to fail.
A compromised liner is the most serious finding a chimney inspection can produce, because gaps in it can expose house framing to flue heat and let carbon monoxide migrate into living space. Relining is how an unsafe flue becomes a safe one without rebuilding the chimney around it.
Signs You Need Chimney Relining
- Camera inspection found cracked or shifted flue tiles
- Tile shards or grit collecting on the smoke shelf
- The home predates ~1940 and may have an unlined flue
- A chimney fire occurred — even briefly
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
How long does a stainless liner last?
The liners we install carry lifetime warranties. Stainless steel handles the corrosive side of combustion byproducts that destroys clay and aluminum, which is why it's the industry's default answer.
Does relining change how my fireplace performs?
Usually for the better — a correctly sized liner often improves draft, especially in oversized old flues where smoke lingered and cooled. We size the liner to the appliance, which is something original construction rarely did.
How soon can you come out?
Routine appointments are usually available within the week, and our 24/7 emergency line handles the situations that can't wait. October and November book fastest — spring and summer scheduling is easiest.
