Quick AnswerIf your flue liner is cracked, missing, or too small for a new furnace, boiler, or insert, relining restores a sealed, code-compliant path for smoke, gas, and carbon monoxide to exit your home. ASH Chimney installs stainless steel liners, cast-in-place liners, and clay tile liner repairs across Cleveland and the North Coast, each sized to the appliance actually connected to it. Every job starts with a camera inspection and a flat-fee written estimate, so you know the exact cost before any work begins. No liner, or the wrong liner, is one of the most common reasons a chimney fails an inspection.
What We Do
Relining isn't one-size-fits-all. The right fix depends on what's damaged, what fuel you burn, and what's connected to the flue. Below are the three relining and repair services we perform most often for homes across Cleveland, Lakewood, Parma, and the rest of the North Coast — click through to any of them for full details.
- Stainless Steel Liner — flexible or rigid stainless steel liners sized to your furnace, boiler, wood stove, or fireplace and rated for the fuel you actually burn, giving smoke, gas, and carbon monoxide a sealed, code-compliant path out of your home.
- Cast-in-Place Liner — a poured, insulated masonry liner that rebuilds a deteriorated or oversized flue from the inside out, restoring structural strength to crumbling chimneys without demolishing the stack.
- Clay Tile Liner Repair — targeted repair or partial replacement of cracked, spalled, or shifted clay tiles when the rest of the flue is structurally sound, sealing the gaps that let heat and combustion gases reach nearby wood framing.
Signs You Need Chimney Relining
- Visible cracks, gaps, or missing pieces in the clay tile liner during inspection
- No liner at all inside an older Cleveland-area chimney
- Crumbling, spalling, or heavily deteriorated flue masonry
- A new furnace, boiler, or insert installed that needs a different liner size
- Past chimney fire, unexplained CO detector alarms, or poor draft
Our Process
Camera Inspection
We run a video scan the full length of your flue to see exactly where the liner is cracked, missing, or undersized — not guess from the rooftop.
Written Estimate
You get a flat-fee, written estimate that spells out liner type, length, and total cost before we schedule any work.
Relining Work
Our technicians install the stainless steel, cast-in-place, or clay tile repair specified in your estimate, sized correctly for your appliance and flue.
Final Safety Check
We test draft and appliance connection, then walk you through the finished liner so you know your chimney is venting safely.
How Much Does It Cost?
Relining cost depends mainly on liner type, flue length, and how much repair the existing masonry needs — a stainless steel liner for a single furnace flue costs less than a cast-in-place liner rebuilding a full masonry stack, and a partial clay tile repair costs less than either. We never quote a relining job over the phone, because pricing without seeing the actual damage is a guess, not an estimate. Instead, we inspect the flue first and hand you a flat-fee, written estimate before any work starts — the number you see is the number you pay, with no surprise add-ons once the crew arrives. If we find additional damage once work is underway, we stop and get your approval before doing anything not already on the estimate.
FAQs
The clearest signs are visible cracks or missing sections in the flue tiles, no liner at all, a chimney fire in the past, or a new furnace or insert that doesn't match your current liner size. A camera inspection is the only way to confirm what's happening inside the flue, since most liner damage isn't visible from the top or bottom.
A stainless steel liner is a sleeve installed inside the existing flue, ideal for venting a specific furnace, boiler, or stove. A cast-in-place liner is poured in place and bonds to the masonry, which makes it better suited for chimneys with badly deteriorated or oversized flues that need structural rebuilding, not just a sleeve.
Yes. A cracked or missing liner lets combustion gases, including carbon monoxide, leak into the chimney structure instead of venting outside, and it lets heat transfer directly to nearby wood framing, which is a documented house fire risk. This isn't a cosmetic repair — it's the difference between a chimney that vents safely and one that doesn't.
