HeatShield Chimney Cleaning in Lawrenceville, GA | Flint Chimney Co Alpharetta
We provide independent HeatShield Chimney Sweep - Lawrenceville and repair across Lawrenceville, GA. Our crew works with HeatShield Cerfractory material daily, and we handle everything from routine sweeps to full liner resurfacing. What makes our HeatShield work different here is simple: we don’t apply more material until we’ve fixed the underlying water problem that caused the failure in the first place. Call (762) 600-1468 for a written quote before anything goes on the calendar.
We’re an independent HeatShield service provider in Lawrenceville. Not manufacturer-affiliated, not authorized, and we don’t pretend otherwise. What we are is a crew that has pulled apart enough failed HeatShield applications in Gwinnett County to know exactly where they go wrong and what it takes to make them right. Hank Delano, our owner, learned the trade at Los Angeles Trade-Technical College and has spent more than two decades on chimneys. He tells every Lawrenceville homeowner the same thing: “Tell me what’s in the flue, and I’ll tell you what it takes to fix it.” That’s the way we run every job, from a basic sweep to a full CeCure reline.
Why Lawrenceville Residents Choose Us for HeatShield Service
HeatShield is not a product you can service well without understanding how it fails in a specific climate. Lawrenceville’s wet, mild winters and summer thunderstorms create a particular set of problems for HeatShield liners, and we see them every week. Our techs have pulled caps off chimneys near the square and in subdivisions off Sugarloaf Parkway, and they can spot the early signs of Cerfractory detachment before a homeowner ever notices grey flakes in the fireplace. That matters because by the time flakes show up, the damage has already traveled further than most people expect.
We run background-checked, uniformed techs on every Lawrenceville call. We hand you a written price before a single tool comes off the truck. And every HeatShield repair carries our 365-Day Done Right Promise: if a covered repair fails within one year, we come back and fix it at no charge. No argument, no invoice. That’s the Garrison Standard, the same code every Garrison Partners location follows, and it’s been in place since 2002.
We also use genuine HeatShield Cerfractory material and mixing kits on every repair. No generic refractory cement that shrinks and cracks after one season. If a Lawrenceville customer asks what we’re putting in their flue, we show them the packaging.

Common HeatShield Chimney Cleaning Problems We Solve in Lawrenceville
- Cerfractory cracking at flue tile gaps. This is the most common HeatShield failure we see in Lawrenceville. The material between flue tiles cracks and falls out, letting moisture and flue gases into the chimney chase. In older downtown Lawrenceville bungalows with original clay tile flues, we often find this around the third or fourth tile joint, right where rain water pools after it enters through an uncracked crown.
- Crumbling, spalled clay tile faces. Before HeatShield can bond properly, the tile surface has to be sound. Years of acidic creosote condensation during Lawrenceville’s humid winters eat at clay tile, and when the face spalls, any joint repair will fail. We wire-brush and rebuild the tile face before applying new Cerfractory. Skipping this step is exactly why so many patches flake off after one rainy season.
- Thin, worn HeatShield resurfacing. Lawrenceville fireplaces get used sporadically through mild winters, which sounds harmless but produces more acidic creosote than steady, hot burns. That creosote condenses on the resurfaced flue wall and slowly wears it down. We see this in 1980s and 1990s homes all over Lawrenceville, particularly where homeowners burn unseasoned wood from the local landscape suppliers.
- Failed top-coat around the smoke chamber. Rain enters through crowns that look fine from the ground, then drips directly onto the resurfaced smoke chamber area. Over a few Lawrenceville rainy seasons, the HeatShield top-coat softens and peels. This is especially common in neighborhoods near the square where many chimneys lack proper crowns altogether.
- Bubbling and detachment from moisture wicking. Lawrenceville’s heavy clay soil holds water against foundation walls. On slab-on-grade homes, that moisture wicks up the chimney mass and pushes against the HeatShield bond from behind. We’ll get to the full explanation below, because this one is the most Lawrenceville-specific failure mode we deal with.
HeatShield Service in Lawrenceville: What Local Conditions Mean for Your Equipment
Lawrenceville sits on clay. Heavy, dense, water-holding clay. And in the 1980s subdivisions off Sugarloaf Parkway, a lot of homes went in on slab-on-grade foundations, which means the chimney masonry sits directly on that clay. When it rains, the soil around the foundation swells and holds water against the concrete. That water doesn’t just sit there. It wicks upward through the masonry, traveling up the chimney mass and into the flue area, where it pushes against the HeatShield Cerfractory from behind. The bond between the Cerfractory and the flue tile fails. The material bubbles and detaches. Homeowners only notice when grey flakes drop into the firebox months later.
This is not a failure mode you’ll see in Alpharetta or Cumming, where the soil drains differently and slab-on-grade construction is less common. It’s a Lawrenceville problem, and it’s why we inspect the foundation-to-chimney connection before we agree to reapply any HeatShield material. If the moisture source isn’t addressed, new Cerfractory will fail the same way. Hank Delano has said it on more than one Lawrenceville job site: the liner is only as good as the chimney behind it.
HeatShield Models & Products We Service in Lawrenceville
We service the full HeatShield line in Lawrenceville, including the HeatShield Cerfractory Flue Sealant, the Joint Repair System, the Resurfacing System, and the CeCure Sleeve Relining system. The first three are repair applications: patching joints, sealing gaps, and recoating worn liner surfaces. CeCure is the full sleeve, installed when the underlying flue tile is too far gone for patching. Our rule is straightforward: if more than 40% of the flue liner surface is spalled or missing, a CeCure sleeve is the honest fix. Patching joints on a liner that’s falling apart costs less today and fails faster tomorrow.
We stock genuine HeatShield Cerfractory material and mixing kits for Lawrenceville jobs. No generic refractory cement in our trucks. For flashings, crowns, and the masonry work that often accompanies HeatShield repair, we use professional-grade materials from trusted chimney trade brands like DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield. What we specify depends on the job, not on the margin.
HeatShield Service Pricing in Lawrenceville
A standard chimney sweep in Lawrenceville typically runs $180 to $340, depending on flue height, buildup, and access. If we find HeatShield damage during the sweep, the repair is quoted separately after a camera inspection. Joint repairs generally run $400 to $900 per joint, and a full HeatShield resurfacing in a standard Lawrenceville flue starts around $2,500. CeCure sleeve relining starts around $3,800, depending on liner length and chimney height. These are ballpark numbers, not shortcuts around the written estimate.
Every Lawrenceville job gets a written price and Chimney Inspection - Lawrenceville before work starts. The number on the invoice is the number you approved. Our estimate includes a camera inspection with a photo report, so you see exactly what we see before deciding anything. Call (762) 600-1468 for an exact quote on your chimney. Estimates are free.

AfterFlashing Repair, Crown Repair, and Spalling Brick Repair in Lawrenceville
HeatShield work rarely exists in isolation in Lawrenceville. The liner is one part of a system, and when we find HeatShield failure, we almost always find the entry point for the water that caused it. Flashing repair, crown repair, and spalling brick repair are the three services we pair most often with HeatShield work here.
Flashing repair: The metal flashing where the chimney meets the roofline is a frequent leak point in Lawrenceville’s 1980s-2000s suburban homes. Rain driven by summer thunderstorms works its way under old flashing, runs down the chimney chase, and compromises the liner from the outside. We replace flashing with new material and proper step-and-counter flashing so water goes where it should.
Crown repair: A lot of Lawrenceville chimneys, especially in the older downtown neighborhoods near the square, have crowns that were poured too thin or pitched inward. That pitch funnels rainwater directly down the flue and onto the HeatShield material. We rebuild crowns with a proper overhang and a positive slope, then seal them. A crown that sheds water correctly extends the life of any liner repair.
Spalling brick repair: When brick faces pop and crumble, it’s a sign water has been freezing and thawing inside the masonry. Spalling brick on a Lawrenceville chimney means the structure itself is compromised, and no amount of HeatShield material will perform well in a chimney that’s falling apart. We cut out and replace damaged brick, then repoint the mortar with a mix matched to the surrounding work.

FAQs – HeatShield Chimney Cleaning in Lawrenceville
The most common reason in Lawrenceville is moisture wicking up through the masonry from the clay soil around your foundation, particularly on slab-on-grade homes off Sugarloaf Parkway. No HeatShield material will bond permanently to a flue that’s constantly damp from behind. We’ll trace the moisture source, fix the masonry or drainage issue, and only then reapply Cerfractory to a dry, prepared surface. Call (762) 600-1468 if you’re tired of watching flakes fall into your firebox every spring.
In most cases, yes. HeatShield is designed to repair flues from the inside, which means we don’t have to demo your brick to fix the liner. We’ll need to camera-inspect the flue first to confirm the tile surface is sound enough to hold a bond. If the clay tile has spalled too heavily, we may recommend a CeCure sleeve instead. Either way, your downtown Lawrenceville brick stays intact.
Yes, HeatShield Cerfractory is rated for use in flues serving gas appliances, and we recommend it for older Lawrenceville gas flues where the clay tile has started to spall or the joints have opened. The material seals out the acidic condensation that gas combustion produces, which is especially hard on older clay tile. We’ll verify your appliance and venting setup before specifying the repair.
HeatShield Cerfractory needs a full cure before it sees heat. We typically recommend 48 hours of cure time, and in Lawrenceville’s humid winter conditions, we may add an extra day if the chimney interior is slow to dry. Using the fireplace before the material cures can crack the new application and void the repair. We’ll give you a specific burn date before we leave.
It depends on what the camera shows. A small crown crack in a Lawrenceville chimney can be sealed without touching the flue, and that’s the cheaper fix if the liner is sound. But if water has been dripping down the flue through that crack, you may have hidden HeatShield damage near the smoke chamber that needs attention. We’ll camera the flue and show you the footage before recommending anything. Call (762) 600-1468 to schedule the inspection.
