Chimney Relining in Lockport, IL
The flue liner is the part of your chimney that does the actual work — containing flame-temperature gases and moving them safely past your framing, your bedrooms, and your roof. When clay tiles crack, shift, or lose their mortar joints, the chimney’s looks don’t change but its safety does. Noble Chimney Sweepers installs stainless steel liner systems that restore a continuous, sealed flue in about a day, backed by camera verification before and after.

How a Reline Works
- Camera scan first. We verify the damage, measure the flue, and confirm liner size — you see the footage that justifies the job.
- Liner installation. A continuous stainless steel liner is lowered from the crown and connected to the appliance or firebox with listed components.
- Insulation. The liner is wrapped or poured-in-place insulated to keep flue gases hot and draft strong.
- Top-out and test. Storm collar, top plate, and cap installed; draft tested; camera pass to document the finished flue.
Why This Is the Fix — Not a Band-Aid
Sleeving a damaged flue in stainless steel isn’t a workaround; it’s what the modern standard calls for. A properly sized, insulated, professionally installed liner typically carries a lifetime manufacturer warranty and outperforms the original clay in draft and creosote behavior. It also future-proofs fuel changes — the same chase can later serve a gas insert with the right liner swap. Compare that to tile-by-tile replacement, which costs more, takes longer, and still leaves you with clay. Our starting price for a full stainless reline is published on the pricing page, and the exact quote comes with the camera evidence attached.
We reline everywhere from older Lockport and Lemont housing stock with original unlined flues to Romeoville and Shorewood homes whose builder-grade tiles didn’t survive a chimney fire. If a Level 2 inspection found liner damage, bring us the report — we’ll give you a straight second read at no charge.
Relining FAQs
How do I know if my chimney needs a new liner?
The tell-tale signs: shards of clay tile in the firebox, a failed Level 2 camera inspection showing cracked or gapped tiles, smoke or odor in rooms adjacent to the chimney, or an unlined flue in a pre-1940s home. A camera scan settles the question definitively — we never quote relining without one.
Why stainless steel instead of new clay tiles?
Replacing clay tiles means breaking into the chimney wall at every damaged joint — slow, invasive, and expensive. A stainless liner installs from the top in a day, carries a manufacturer lifetime warranty when professionally installed, and handles both wood and gas applications. It’s the industry-standard fix for damaged flues, not a shortcut.
Does a new liner need insulation?
In most cases, yes — an insulated liner keeps flue gases hot, which improves draft and dramatically slows creosote formation. Insulation is also required for the liner’s listing in many wood-burning applications. We quote the liner and insulation together so there’s no surprise add-on.
How long does relining take?
Most single-flue reline jobs are done in a day: measure and confirm in the morning, drop and connect the liner, insulate, fit the top plate and cap, and test the draft. Complex offsets or smoke chamber work can add a second day — you’ll know before we start.
Can you reline a flue for a gas furnace or water heater?
Yes, and it matters more than most homeowners realize. Modern high-efficiency gas appliances send cooler, wetter exhaust up flues sized for older equipment — the condensation eats clay tile and mortar from the inside. An aluminum or stainless liner sized to the appliance is the correct fix and is required by code in many replacements.
Will a liner change how my fireplace drafts?
Usually for the better. A correctly sized liner often improves draft, especially on oversized older flues that never drew well. Sizing is the critical variable — too small chokes the fire, too big cools the smoke — which is why we measure the firebox opening and flue height rather than guessing.
What happens to the old clay tiles?
In most installs the liner runs inside the existing tiles, damaged or not — they become an outer shell. If tiles are collapsed or offset enough to block the path, we break out the obstruction first. Either way the new liner is a continuous, sealed path from appliance to cap.
Is relining really necessary if I only use the fireplace a few times a year?
If the flue is compromised, yes. A cracked liner leaks combustion gases and heat into the house structure whether you burn nightly or twice a winter — and occasional fires in a cold, damaged flue actually draft worse. The honest alternative to relining is not using the fireplace at all; we’ll tell you plainly which situation you’re in.
