HeatShield Chimney Cleaning in Roswell, GA | Alcott Chimney Marietta
We provide independent HeatShield chimney cleaning and repair across Roswell, and the one thing that sets our HeatShield work apart here is simple: we know what Roswell’s local red clay flue tiles do to ceramic coatings over time. Most HeatShield failures we see aren’t product defects. They’re what happens when a good coating meets Roswell’s humid summers, occasional ice storms, and clay that expands and contracts in ways modern terra cotta doesn’t. Call (229) 350-8952 for a free estimate, and we’ll show you exactly what’s happening inside your flue before recommending anything.
We’re Alcott Chimney Marietta, and we’ve been doing HeatShield sales & service across the north metro since long before most Roswell homeowners had heard of ceramic flue resurfacing. Ruben Castellano leads our crew, and he’s the kind of person who will tell you when a HeatShield repair is the right call, and when it isn’t.
Why Roswell Residents Choose Us for HeatShield Service
HeatShield isn’t a product you want installed by someone who learned it from a brochure. The Cerfractory sealant has to bond to whatever’s already in your flue, and in Roswell, that’s usually dense red clay tile from the old Chattahoochee Brick Company days. Ruben’s spent well over a decade on Chimney Sweep - Roswell and inspection, and his crews have applied HeatShield to enough of Roswell’s 1980s and 90s chimneys that we can usually predict how a liner will behave before we even put a camera up there.
We carry genuine HeatShield Cerfractory sealant, Joint Repair mortar, and CeCure stainless sleeves. We don’t substitute generic refractory coatings, because those don’t bond reliably to Roswell’s particular clay. And we’re independent: we’re not paid or endorsed by the manufacturer, which means we recommend HeatShield only when it’s the right fix for your chimney, not because we have a quota to hit.
Every technician who arrives at your door is background-checked and identity-verified under the Threshold Standard. You’ll know the technician’s name and see their photo before we arrive, and they’ll show a photo ID badge at the door. That’s not an upgrade. It’s how we’ve operated since 2002.

Common HeatShield Chimney Cleaning Problems We Solve in Roswell
- Creosote buildup behind failing HeatShield coatings. Roswell homeowners often burn unseasoned hardwood for ambiance rather than heat, and that wet wood produces heavy creosote. When hairline cracks in the underlying clay tile let that creosote seep behind a HeatShield coating, it creates a fire risk that a standard sweep alone won’t fix. We remove the creosote, then address the coating failure.
- Hairline cracks in original red clay tile liners. This is the Roswell signature. The dense, high-iron clay from the Chattahoochee Brick Company expands and contracts differently than modern terra cotta, and after decades of heating and cooling, hairline fractures appear. HeatShield Cerfractory seals them, but only if the surface is properly prepared first. Skip prep and the coating delaminates within a season.
- Spalling and flaking of older HeatShield coatings. Roswell’s humid subtropical climate means summer condensation sits inside flues for months. Repeated thermal cycling, intermittent fires, then humid idle periods, causes older Cerfractory applications to spall and flake. We see this most often in homes where the fireplace gets used for a few weeks in December, then ignored until March.
- Failed joint repair mortar at flue tile seams. Roswell’s occasional ice storms bring freeze-thaw cycles that punish masonry. If a previous HeatShield Joint Repair System application used the wrong mortar mix, or was applied over a dirty joint, it shrinks and cracks within a year or two. We re-point those joints and re-coat.
- Corrosion at the top of CeCure stainless sleeves. Burning unseasoned wood creates acidic condensate, and that condensate collects at the top termination of a stainless sleeve. Over several Roswell winters, we see pitting and rust at the cap and first few inches of the sleeve. It’s a reminder that even stainless needs an annual look.
HeatShield Service in Roswell: What Local Conditions Mean for Your Equipment
Here’s the Roswell-specific fact that shapes how we schedule HeatShield work: the red clay tile flue liners in your chimney came from the now-defunct Chattahoochee Brick Company, and their dense, high-iron clay expands and contracts on a different schedule than modern terra cotta. The hairline fractures that make HeatShield necessary often open only during Roswell’s humid summer nights, when the clay absorbs moisture and swells. By mid-afternoon, the crack can close up enough that a camera scan misses it entirely. That’s why we schedule Chimney Inspection in Roswell in the early morning, before the day’s heat dries things out. If we’re going to apply Cerfractory to your flue, we want to see every fracture that will be underneath it, not just the ones that happen to be visible at 3 p.m.
This matters for homeowners in neighborhoods like Martin’s Landing and Crabapple, where 1980s masonry chimneys are common. A morning inspection gives us a complete picture, which means the HeatShield application actually lasts. Skip that step and you’re coating over problems you can’t see, and the coating will fail just like the last one did.
Last fall our crew serviced a HeatShield-lined masonry chimney on Canton Street near the Roswell Mill. The homeowner reported a smokey smell during evening fires. A camera inspection revealed a vertical crack in the 1984 red clay tile behind a deteriorating HeatShield CeCure sleeve. We removed the old coating, re-pointed the joint with HeatShield Joint Repair mortar, and re-coated with Cerfractory. No odor since.
HeatShield Models & Products We Service in Roswell
We work with the full HeatShield product line. The Cerfractory Flue Sealant is the workhorse for sealing hairline cracks and minor spalling. The Joint Repair System addresses gaps at flue tile seams where mortar has failed. The Resurfacing System is a full interior re-coat for liners with widespread deterioration. And the CeCure Sleeve Relining System is a stainless steel sleeve installed when the underlying masonry is too far gone for ceramic coating alone.
On the parts side, we stock genuine HeatShield materials locally, which means faster turnaround for Roswell jobs. If your flue needs a re-coat, we’re not waiting on a shipment from a warehouse. We carry OEM Cerfractory and Joint Repair mortar on our trucks because that’s what bonds to Roswell’s dense clay. Generic refractory products don’t, and we won’t use them.
When a liner has multiple failed repairs, or a previous contractor applied HeatShield over an unprepared surface, we recommend full removal and reapplication over spot patching. Patching a patch is how you end up calling us back next year.

AfterHeatShield Service Pricing in Roswell
A standard chimney sweep in Roswell typically runs $189 to $329 before any repairs, and that includes creosote removal and a visual check of your flue. A Level 2 camera inspection, which we recommend before any HeatShield application, adds $149 to $249 depending on the chimney’s height and access. HeatShield Joint Repair work generally starts around $400 to $800 per joint, while a full Cerfractory resurfacing for a typical 1980s Roswell masonry chimney runs $2,500 to $4,500. A CeCure stainless sleeve reline typically falls between $3,500 and $6,500 including the sleeve, installation, and a final camera verification.
Those are real ranges we’ve quoted for Roswell homes in the past year. Your exact number depends on flue height, the condition of the existing liner, and how much prep work the surface needs. Every estimate includes a written price before any work starts, and a written guarantee on every repair. If the repair fails within the coverage period, the second visit is free. Call (229) 350-8952 for a free estimate with no obligation.

FAQs – HeatShield Chimney Cleaning in Roswell
Roswell’s humid summers mean moisture sits inside your flue for months at a time, and that moisture works its way into any small gap between the HeatShield coating and the clay tile behind it. Over repeated humid seasons, trapped moisture can cause the coating to lift or delaminate, especially if the original surface wasn’t properly prepped. That’s why we insist on a morning camera inspection before any application, and why we schedule a follow-up look at the one-year mark for every HeatShield job in Roswell. If you’re noticing flaking or a powdery residue inside your firebox, call (229) 350-8952 and we’ll put a camera up there.
Yes, HeatShield Cerfractory sealant is designed specifically for hairline cracks in clay tile liners, and it bonds well to the dense red clay common in Roswell’s 1980s brick chimneys, provided the surface is cleaned and prepped correctly first. The key is catching the cracks when they’re visible. Roswell’s clay tile expands with summer humidity and contracts in dry winter air, so a crack that’s obvious in July might be nearly invisible in January. Call (229) 350-8952 for a free estimate, and we’ll schedule the inspection at the right time of day to see what’s actually there.
Yes, and in some ways Occasional use is the scenario HeatShield handles best. A fireplace near the Chattahoochee in one of Roswell’s historic mill village cottages tends to burn a few fires a year, then sit idle through humid seasons. The ceramic coating seals the flue against moisture intrusion during those idle months, which actually helps prevent the spalling and efflorescence that plague unused chimneys in this climate. We’d still recommend an annual inspection, because intermittent use can hide problems. But HeatShield is a sensible fit for those homes. Call (229) 350-8952 and tell me what you’re seeing, and I’ll tell you exactly what it means, no guesswork, no upsell.
Joint Repair addresses specific gaps at the seams between flue tiles, where mortar has shrunk or cracked. It’s a targeted fix: re-point the joint, seal it, done. A full Resurfacing is a complete interior re-coat of the entire flue, used when deterioration is widespread, not just at the joints. For most Roswell 1980s chimneys with hairline cracks in the tile bodies themselves, not just at the seams, we recommend resurfacing. Joint repair alone would leave those tile-body cracks open. The camera inspection tells us which one you actually need. Call (229) 350-8952 for an exact quote, estimates are free.
Yes. We warranty every HeatShield application we perform with our 365-Day Done Right Promise: if the work isn’t right, we make it right, and if a repair fails within the coverage period, the second visit is free. That’s our written guarantee, and it doesn’t depend on a manufacturer authorization. We’re factory-trained in HeatShield application methods, but we’re independent, which means our accountability is to you, not to a brand. If a HeatShield coating we applied delaminates within the year, you’ll have a crew back here fixing it at no charge. Call (229) 350-8952 for a free estimate.
