Do I need a new liner, or can my existing one be repaired?

It depends on which liner type you have and how it failed. Clay tile liners with a few cracked tiles near the top or with deteriorated joints between sections can sometimes be repaired in place. Clay tile liners with cracked tiles deeper in the flue, multiple failure points, or evidence of post-fire thermal damage usually need to be relined with stainless steel. Existing stainless steel liners are almost never repaired — they're either fine or replaced. The camera inspection determines the answer; we won't push relining when targeted repair will actually solve the problem.

What's the difference between a clay tile and a stainless steel liner?

Clay tile is the original construction material — terracotta sections stacked inside the chimney during the original build, held with refractory mortar. Stainless steel is a flexible or rigid pipe that gets installed inside the existing flue, usually as a replacement when the clay tile fails. Clay tile is heat-tolerant and long-lasting when intact, but vulnerable to thermal shock from chimney fires. Stainless steel is more flexible (literally and figuratively) — it can be sized to any appliance, requires less work to install in an existing chimney, and has well-defined lifespans by alloy grade. Most relining work we do is clay-tile-to-stainless-steel because the original liner failed.

How long does a stainless steel liner last?

Stainless steel liners commonly last 15–30 years, depending on liner grade, fuel type, moisture, and creosote exposure, and maintenance. 304 or 316 stainless on a wood-burning fireplace, properly insulated, sits at the lower end of that range. 316Ti (titanium-stabilized) stainless steel on a gas appliance often hits the upper end — gas exhaust is less abrasive than wood smoke, but more chemically aggressive (condensate). The biggest predictors of liner lifespan are correct sizing for the appliance, proper insulation per code, and proper installation (no kinks, no over-stretching). Cheaper alloys or lighter-gauge material installed by lower-quality vendors can fail in 5–10 years.

Is a chimney liner required by code in North Carolina?

Yes, for active appliances. NC residential code (which references IRC and NFPA 211) requires every chimney attached to a wood-burning fireplace, wood stove, fireplace insert, gas log set, gas insert, oil furnace, or wood furnace to have a properly-sized, properly-rated liner. Unlined chimneys can exist on inactive or decorative-only chimneys but cannot legally support an active appliance. If you're converting from wood to gas or installing any new appliance, code requires the liner to match the new appliance — this is the most-frequently-skipped step in DIY appliance installs.

I'm converting from wood-burning to gas logs. Do I really need a new liner?

Usually yes. Gas logs produce a different exhaust profile than wood — lower temperature, higher moisture content, sometimes more chemically aggressive, depending on fuel — and the original liner sized for wood-burning is typically wrong for gas. Skipping the reline is a common code violation and can cause condensation problems that damage the masonry behind the liner. The required liner is usually a smaller-diameter stainless steel liner sized to the gas log set's BTU rating. Cost is typically modest compared to a full reline. We coordinate scheduling with your gas log dealer when relevant.

Can a regular chimney inspection find liner problems?

Only sort of — and this is why Level 2 inspections (which include camera scope) are different from Level 1 inspections (visual only). A Level 1 inspection looks at what's visible from the firebox and chimney top. A Level 2 inspection adds camera scoping of the entire flue length, which is the only reliable way to find cracked clay tiles, joint deterioration, kinks in stainless steel, or unlined sections. If your chimney has had a chimney fire, you've changed appliances, or there's a real estate transaction in progress, a Level 2 inspection (with the camera) is what you actually need — not just a Level 1.

Is it safe to use my fireplace if my liner has issues?

Usually, no — and usually depends on the specific issue. A small crack near the top of the flue might be lower risk than a major crack deep in the system; deteriorated joints between tiles can be incrementally worse than a single hairline crack. The honest answer is that without seeing the actual condition on camera, we can't tell you it's safe to use. After we run the camera, we tell you definitively: safe to use as-is, to use with limitations until repair, or do not use until liner is corrected. We won't sign off on a chimney we wouldn't burn in ourselves.

What is a Level 2 inspection?

Level 2 is a formal industry inspection standard (defined by NFPA 211) that's more thorough than a routine annual cleaning visit. It includes camera scoping of the full flue length, evaluation of the liner condition, evaluation of clearances to combustibles, and a written report. Level 2 is required after a chimney fire, before any appliance change (wood-to-gas conversion, new stove install), and for most real-estate transactions.

Does insurance cover chimney liner replacement?

It depends on the cause. Liner damage from a sudden event — chimney fire, lightning, vehicle impact — is usually covered by homeowner's insurance, and we provide post-fire camera-inspection reports formatted to support insurance claims. Liner deterioration from gradual age, normal wear, or improper original installation is typically not covered (treated as maintenance). For chimney fires specifically, document everything: the fire department report (if you called them), the dispatch record, and our post-fire camera-inspection findings. Insurance claims are easier when the documentation chain is clean.

How long does a typical relining project take?

Camera inspection: 45–60 minutes. Quote: same-day to 48 hours after inspection. Install timing: stainless steel reline (single-wall) — 1 day; stainless steel reline (insulated) — 1–1.5 days; cast-in-place liner — 1–2 days plus cure time; clay tile section repair — half-day to 1 day; appliance-coordinated relining (e.g., for a new wood stove) — scheduling depends on stove install date. Most reline projects from camera inspection to completed installation happen within 1–3 weeks.

Are you certified and insured for liner work?

Yes. Perfect Chimney is CSIA Certified — Chimney Safety Institute of America Certification #12553 — and CSIA's certification program includes specific competency standards for liner installation and code compliance. We carry general liability insurance through Spinnaker Insurance Company and workers' compensation through AM Trust. Documentation is available on request before any work begins. For liner installs that involve appliance coordination, we work with stove and insert dealers to make sure the liner spec matches the appliance manufacturer's installation requirements.

Chimney Liner & Flue Repair | Greensboro & Raleigh, NC

Your chimney liner is the thing that makes your fireplace safe to use. It's the protective shell inside the chimney that contains the heat, channels smoke and combustion gases up and out of the home, and keeps superheated air from contacting the surrounding masonry where it could ignite framing wood or crack the structure. When a liner fails due to cracked clay tiles, deteriorating mortar joints, a corroded steel liner, or no liner at all, the chimney cannot do its job safely. Carbon monoxide can leak into living spaces. Chimney fires become more likely. And in real-estate transactions, an unsafe liner is the most common reason a fireplace gets flagged as do not use until repairs are made.

At Perfect Chimney Cleaning, our CSIA-certified technicians repair, reline, and replace chimney liners across the Piedmont Triad and the Research Triangle. We work on all three liner types — original clay tile, stainless steel relining systems, and cast-in-place insulating liners — and we resize flues when homeowners convert from wood-burning to gas, install wood inserts, or change appliances in ways that require different draft characteristics. Every liner job we do starts and ends with a camera inspection, so you see the actual condition of the flue before work begins and verified results after.

Whether your inspection turned up cracked tiles, you're smelling smoke or odor that suggests a draft problem, you've had a chimney fire and the liner needs evaluation, or you're installing a gas insert or wood stove that requires a properly-sized liner — one call gets you a real CSIA-trained technician, an honest camera-verified diagnosis, and a written quote that breaks down repair vs. relining and explains which option actually fits your chimney and appliance.

Clay Tile · Stainless Steel · Cast-in-Place — All Three Liner Types

Almost every chimney built since the 1920s has a liner of some kind. There are three main types, each with its own materials, lifespan, and failure modes. Knowing which type you have is the first step in deciding whether your liner needs repair or full replacement. Most homeowners don't know their liner type — that's normal — and a camera-verified inspection is what tells us definitively.

Here are the three liner types we work with and how each one tends to fail. Your chimney almost certainly has one of these. (If it has none — which happens on older or improperly-built chimneys — that's its own situation, addressed at the end of this section.)

Clay tile is the original chimney liner material — terracotta rectangular flue tiles stacked vertically inside the chimney, held together by refractory mortar between each tile section. Most chimneys built between 1920 and 1990 in North Carolina have clay tile liners. When clay tile is intact, it works well — it's heat-resistant, dimensionally stable, and typically lasts 50–100+ years when properly maintained and not exposed to severe moisture or chimney fires. When it fails, it fails in one of three ways: cracked tiles (from thermal shock after a chimney fire, or from a foundation shift), deteriorated mortar joints between tiles (which lets heat and combustion gases escape into the masonry behind the liner), or spalling on the tile face (which roughens the flue and accelerates creosote accumulation). Cracked or joint-failed clay tile is not safely usable until repaired.

Stainless steel liners are the modern relining material — flexible or rigid stainless steel pipe sized to fit inside the existing flue, often wrapped with insulation. They're the default choice when an old clay tile liner has failed beyond repair, when a fireplace is being converted to a wood stove or insert, or when a homeowner is switching from oil heat to gas. A properly-installed stainless steel liner with the right thickness, alloy, and insulation lasts 15–25 years on wood burning use and longer on gas. Stainless steel fails by corrosion (when undersized for the appliance, or when condensate from a gas appliance attacks the alloy), by physical damage during installation (kinked sections from over-aggressive feed), or by inadequate insulation (which creates condensation problems and shortens lifespan). We use 316Ti or better alloy for gas appliances and 316 or 304 for wood-burning use, sized to the appliance manufacturer's specifications.

Cast-in-place liners are a poured-in-place insulating cementitious material that bonds to the inside of the existing flue, forming a smooth, seamless lining without a metal pipe. They're the premium option for older chimneys where stainless relining isn't a good fit, or where the chimney needs structural reinforcement as well as relining. Cast-in-place liners often last 50+ years with proper installation and maintenance, improve chimney structural integrity, but cost more than steel relining and require specialized equipment to install. They fail by sectional cracking (rare, usually due to foundation movement) or by installation defects caused by inexperienced installers.

Some older chimneys (especially pre-1920 construction) were built without any liner — the bare brick or stone interior of the chimney served as the flue. Modern code does not allow this configuration on active appliances; an unlined chimney attached to a wood-burning fireplace, wood stove, or gas appliance is considered unsafe by current standards. If your chimney is unlined and you want to use the fireplace or install a heating appliance, we install a stainless steel or cast-in-place liner sized for the intended use. Until that's done, the chimney should not be used.

North Carolina building code (which follows IRC and NFPA 211 standards) requires a properly-sized, properly-rated liner whenever you change the appliance attached to the chimney. The most common situations: converting a wood-burning fireplace to gas logs (requires a liner sized for the BTU rating of the gas log set), installing a wood stove or fireplace insert (requires a liner sized for the insert's outlet, usually 6 inches), upgrading from gas logs to a direct-vent insert (requires a dedicated stainless steel liner), or converting from oil heat to gas (the chimney often needs a smaller, properly-sized liner because gas combustion produces lower-temperature exhaust than oil).

Skipping this step is one of the most common code violations we see during inspections — and the most expensive one to remediate, because it usually means tearing out improperly installed work and starting over. We make sure liner sizing matches your appliance and current code before we install.

Liner work starts and ends with the chimney camera. You cannot diagnose a liner problem from the outside — every flue is a vertical tube hidden inside masonry, and the only way to actually see what's going on is to lower a camera down it. We document the inspection with high-resolution still photographs (we don't shoot video — photos give us higher detail per frame and a clearer record for written reports), and after the repair or relining, we run the camera again and document the result. Here's our process, step by step.

For routine liner inquiries — annual inspection findings, planning an appliance install, or real-estate closing — you'll hear back from us the same day or within 24 hours, and we'll schedule a camera inspection usually within the same week. For urgent situations — recent chimney fire, active CO alarm activity correlated with appliance use, or a real-estate closing with a tight deadline — call our line directly and we'll prioritize. After-hours fees may apply for non-emergency requests.

A CSIA-certified technician arrives on time and lowers a high-resolution chimney camera through the full length of the flue, capturing detailed still photographs of every joint, every section of liner material, and every condition we find. We document liner type (clay tile, stainless steel, cast-in-place, or unlined), specific failure points (cracked tiles, joint deterioration, corrosion, kinks, gaps), and any other safety issues we encounter (chimney fire damage, animal nesting, creosote glaze). The full camera inspection typically takes 45–60 minutes and produces a photo report you keep — regardless of whether you proceed with repair through us.

Not every liner problem requires full relining. Sometimes, targeted repair — replacing a few cracked clay tiles, re-mortaring deteriorated joints, or patching a localized corrosion spot — is the right answer and saves thousands of dollars. Other times, the liner is failed enough that relining is genuinely the only safe option. After the camera inspection, we walk you through what we saw, which liner type you have, what each repair option would address, what each option would cost, and which one we'd recommend if it were our chimney. The recommendation is yours to accept, modify, or reject.

If relining is the right path, the written quote includes the exact liner specification we'd install — diameter, length, alloy or material, insulation type, and the appliance it's sized to. This level of detail matters because the wrong liner spec for your appliance is a code violation and a safety problem; the right spec is documented in the quote so you (and any home inspector or insurance adjuster) can verify it later. We also list the safety codes the spec satisfies (NFPA 211 most commonly, plus any local Greensboro or Raleigh municipal amendments).

If you proceed, we install the liner system, complete any associated work (smoke chamber correction, top-plate sealing, appliance connector verification), and then run the camera back through the new liner top to bottom and document the result with a fresh set of photographs. The post-install photo report is yours — you can show it to a home inspector, attach it to your insurance file, or just keep it for future reference if you ever sell the home. Camera-photo verification is not standard industry practice; we do it because it's the only way to actually prove the install was done right.

Repair Type	What's Done	Typical Scope	Notes
Clay Tile Mortar Joint Repair	Re-mortar deteriorated joints between existing clay tile sections using refractory mortar; verify result with camera.	Half-day to 1 day, depending on access.	Works only when the tiles themselves are intact. Failed tiles require relining.
Clay Tile Section Replacement	Remove and replace individual cracked clay tile sections, re-mortar to adjacent sound tiles.	1–2 days; sometimes requires masonry access to chimney exterior.	Realistic only for tiles near the top of the flue; deep tile replacement usually means relining.
Stainless Steel Relining — Single-Wall	Install flexible or rigid single-wall stainless steel liner sized to existing flue and intended appliance.	1 day for most installs.	Best for wood-burning fireplaces and gas appliances where insulation isn't required by code.
Stainless Steel Relining — Insulated	Install stainless steel liner with insulation wrap or pour-in vermiculite insulation.	1–1.5 days depending on insulation method.	Required for most wood stove and insert installs. Extends liner lifespan.
Post-Install Camera Verification	Camera-photograph the completed liner from top to bottom; produce photo report for homeowner records.	30–45 minutes after install.	Included with every liner job — your verification, not standard industry practice.

In some cases, smoke chamber or flue defects can be corrected using HeatShield® resurfacing or repair methods instead of a full chimney relining system. Our certified technicians evaluate the condition of the chimney to determine the safest and most cost-effective repair option.

Most liner projects combine 2–4 of these items — for example, a wood stove install typically includes: insulated stainless steel relining + smoke chamber correction + top plate + termination cap + post-install camera verification. The written estimate breaks down each line item separately so you see exactly what you're paying for.

We schedule the camera inspection first. The inspection produces a photo report and a recommendation (repair vs. relining, with specific liner spec if relining). The written quote is delivered after the inspection (typically same-day or within 48 hours) and includes exact specs: liner type, diameter, length, alloy, insulation method, and the appliance it's sized to. There is no obligation to use Perfect Chimney Cleaning for the work — the inspection findings and photo report are yours regardless. For relining work that involves an appliance install, we coordinate scheduling with your stove or insert dealer.
