Chimney Relining
There’s a part of your chimney you’ve probably never seen — and if the liner is cracked, deteriorating, or missing entirely, that’s a problem worth taking seriously. The flue liner is the inner layer that does the real work: it contains the heat from your fire, directs combustion gases safely out of your home, and protects the surrounding masonry from the intense conditions inside the flue. When it fails, those gases — including carbon monoxide — have a path into your living space, and heat can transfer directly to the wood framing around your chimney. It’s one of the most dangerous conditions a home can have, and you’d never know it just by looking at the fireplace. At LKN Chimney Sweep, we handle chimney liner installation throughout Statesville, Mooresville, Troutman, Denver, and the greater Lake Norman area, and everything we do follows NFPA 211 chimney standards.
When Your Flue Liner Needs Replacement
Most homeowners don’t discover a liner problem until a video inspection reveals it. That’s not a flaw in the system — it’s just the nature of what a flue liner is. It sits inside the chimney, hidden from view, and damage to it only shows up when you look with a camera.
The most common reasons we reline a chimney are cracked or broken flue tiles, which can happen gradually from age and moisture or suddenly after a chimney fire. Acidic flue gases from gas appliances are especially hard on older clay tile liners and can eat away at the mortar joints over years. We also see a lot of liner defects come up during home purchase inspections — the previous owners had no idea, and now a buyer in Statesville or Cornelius is facing a repair before they can safely use the fireplace.
Other situations that call for relining include switching from gas to wood-burning, adding a wood stove insert to a previously open fireplace, chronic draft problems like smoke backing into the room, or any time a chimney fire has occurred — even a small, unnoticed one. That’s exactly why we require a Level 2 video inspection for every new client before we do any cleaning or servicing. If there’s a liner issue, the footage makes it completely clear.
Stainless Steel Chimney Liner Options
Stainless steel is the industry standard for relining, and for good reason. It handles high flue temperatures, resists corrosion from acidic gases, and lasts for decades when properly installed. The alloy grade we use is matched to your specific appliance — the requirements for a wood-burning fireplace are different from those for a gas insert or oil furnace, so liner selection isn’t one-size-fits-all.
Rigid Stainless Steel Liners
When your chimney runs straight from firebox to cap with no offsets, a rigid stainless steel liner is typically the right choice. The smooth interior promotes excellent draft, and the rigid construction is extremely durable over time. This is what we install in most newer chimney configurations around Statesville where the flue path is straightforward.
Flexible Stainless Steel Liners
Older homes — and there are plenty of them in the Lake Norman region — were often built with chimneys that have offsets, bends, or interior dimensions that don’t conform to modern standards. A flexible stainless steel liner is designed exactly for these situations. It conforms to the existing flue path without requiring any structural changes to the chimney itself, which makes it the practical choice for a lot of the historic homes we service in and around Statesville.
Regardless of which liner type fits your chimney, we also factor in insulation wrap where required — particularly for wood-burning applications, where the liner needs to maintain higher temperatures to produce a strong draft and reduce creosote buildup. Every installation meets NFPA 211 standards and applicable local building requirements.
Damaged Flue Repair vs. Full Relining
Not every liner problem means a full replacement. When damage is limited to a small section and the rest of the liner is structurally sound, a targeted repair approach — like a sealant-based resurfacing system applied to the interior flue walls — can restore the system without the cost of a complete reline. We use this approach when the inspection shows isolated cracks or minor deterioration that hasn’t spread.
Full relining makes more sense when the damage is widespread, when flue tiles are separating at joints throughout the chimney, or when the original liner was simply the wrong size or type for the appliance currently in use. An undersized or oversized liner causes chronic draft problems that no amount of cleaning will fix.
The inspection footage tells us which path is appropriate. We show homeowners the video so they can see exactly what we’re seeing — there’s no guesswork, and we’re not going to recommend a full relining when a targeted repair is all that’s needed. Either way, the goal is getting your system back to chimney safety code compliance.
If you’ve had a recent inspection that flagged liner damage, or if you’re dealing with draft issues that have never been fully explained, give us a call. (704) 610-6388 — we’re happy to talk through what you’ve got before you commit to anything.
The Chimney Relining Process
Most homeowners have never been through a chimney relining, and the biggest concern we hear is “how disruptive is this going to be?” Not very. Most residential relinings are completed in a single day.
Inspection and Assessment
Before any installation, we run a Level 2 video inspection to map the full interior condition of your flue — dimensions, offsets, any obstructions, and the condition of the existing liner. We take precise measurements and review the appliance specifications so the new liner is sized correctly from the start. You’ll see the footage and get a written assessment with photos before any work begins. No surprises.
Installation Day
We protect your home the same way we do during every job — tarps around the hearth, HEPA-filtered vacuums running throughout. If broken flue tiles need to come out, we handle that as part of the process. The new stainless steel liner is fed down through the chimney from the top and connected to the firebox or appliance at the bottom. Where insulation wrap is required, it goes on during this step. We cap the top of the liner with a new chimney cap to seal and protect the termination point. Once everything is in place, we do a final draft test and safety check before we leave.
Chimney Liner Cost Factors
Chimney liner cost in North Carolina varies depending on several things specific to your chimney and home. The liner material and alloy grade affect the base cost, since different fuel types require different specifications. Chimney height, the presence of offsets, and how accessible the roofline is all factor into labor. If the old tile liner needs to be removed, that adds time. Insulation requirements, the cap, and the connector components at the appliance end all contribute to the final number as well.
We offer financing through Wisetack for customers who’d rather spread the cost out — it’s worth asking about when you call. And while we don’t publish set prices because every chimney is different, we provide detailed written estimates after the inspection so you know exactly what you’re getting and what it costs. A properly installed liner protects your home for 15 to 25 years or more, prevents structural damage from heat and moisture, and eliminates the carbon monoxide risk that comes with a compromised flue. Most homeowners, once they see the inspection footage, feel a lot better about the investment.

Frequently Asked Questions
How long does the relining appointment take?
Most residential chimney relinings are completed in a single day. If your chimney is particularly tall, has multiple offsets, or requires significant tile removal before the liner can be installed, it could run longer — we’ll let you know during the estimate process so you can plan accordingly.
Do I need to be home during the relining?
We do ask that someone be home at the start of the job so we can review the work plan and make sure you’re comfortable with the process. Once things are underway, you don’t need to hover — we’ll check in with you when we’re done and walk you through the final inspection before we leave.
How far in advance should I schedule?
Availability varies by season, but it’s always a good idea to call sooner rather than later — especially heading into fall when demand picks up across the Statesville and Mooresville areas. If your liner is already flagged as damaged, don’t wait; using a fireplace with a compromised liner creates real safety risks.
Is there a warranty on the new liner?
Warranty coverage depends on the liner material and alloy grade selected for your installation. Certain stainless steel alloys come with lifetime warranty options from the manufacturer. We’ll go over the specific warranty terms during the estimate so you know exactly what’s covered before you commit.
What should I do to prepare before installation day?
Clear the area around your fireplace and hearth so we have room to work and set up our equipment. If you have fragile items on the mantel, it’s a good idea to move those as well. Beyond that, there’s not much you need to do — we bring everything we need and handle the cleanup before we leave.
Do you offer financing for chimney relining?
Yes — we offer financing through Wisetack, which lets qualified customers spread the cost of larger repairs over time. Ask us about it when you call, or mention it when you request a quote and we’ll send you the prequalification information.
What happens if the inspection finds other issues beyond the liner?
We’ll document everything we find and walk you through it before any work begins. If there are additional concerns — like a damaged crown, flashing issues, or creosote buildup — we’ll explain what they are and what your options are. Nothing gets added to the scope of work without your approval first.
Can a new liner be installed if the old one is partially intact?
It depends on what’s there and its condition. In some cases, we can work around a partial liner; in others, sections need to be cleared before the new liner can be properly seated and connected. The Level 2 video inspection gives us the information we need to answer that specifically for your chimney before we touch anything.
