Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

We provide independent Chimney Sweep - Alpharetta service for DuraFlex systems across GA, and we do it without the manufacturer’s bias or markup.

Call (762) 600-1468 for a free estimate.
We’re Flint Chimney Co Alpharetta, part of the Garrison Partners family founded in 2002. Hank Delano leads our crew, and he’s spent over two decades pulling creosote out of flues, including the DuraFlex 316L liners common throughout Alpharetta. We’re not manufacturer-affiliated or authorized by DuraFlex. We’re independent. That means we tell you what’s actually in your flue and what it needs, not what a brand rep wants you to buy.
Why Alpharetta Residents Choose Us for DuraFlex Service
Most chimney companies in Alpharetta will clean whatever liner you have. Few can talk about the difference between a corrugated DuraFlex 316L liner and a smooth-wall Pro liner, or why that difference matters in a humid Georgia winter. We can, because we’ve spent years inspecting, cleaning, and repairing these exact systems in homes from Windward to Crabapple to newer builds near Avalon.
Hank learned the trade at Los Angeles Trade-Technical College and has been on roofs long enough to know that a liner’s alloy composition matters as much as how often it’s swept. Our technicians are background-checked, uniformed, and trained on DuraFlex’s specific liner profiles. We stock genuine DuraFlex components locally, so a repair doesn’t wait on a slow parts shipment. And like every Garrison Partners location, we operate under The Garrison Standard: a written price before any work starts, a live person on the phone 24/7, and the 365-Day Done Right Promise on every repair. If a covered repair fails within a year, we come back free. No argument.

Common DuraFlex Chimney Cleaning Problems We Solve in Alpharetta
- Creosote packed into corrugated ridges. DuraFlex’s flexible liners have ridges that trap creosote far more aggressively than smooth-wall models. In Alpharetta, where high humidity keeps that creosote sticky and heavy, we regularly find ridges filled solid after a single burning season. Standard brushing often isn’t enough; we use rotary heads and hand-scraping to clear what a basic sweep leaves behind.
- Pitting corrosion on 316L alloy. The 316L stainless in most DuraFlex liners resists corrosion well, but acidic creosote sitting in humid conditions can still pit the metal. We’ve seen this in Alpharetta homes where fires burn low and slow, producing wet, acidic smoke. The pitting doesn’t always crack the liner, but it weakens it and gives creosote more surface to grip.
- Sagging or ovalized liners in taller chimneys. Improperly supported DuraFlex liners can sag over time, especially in the taller two-story and three-story chimneys common in Alpharetta’s 1990s and 2000s builds. When a liner sags, it creates dead air pockets where smoke cools and creosote drops out of suspension. We check liner tension and support points on every inspection.
- Clogged tee connections at the base. The tee fitting where a DuraFlex liner connects to the appliance is a collection point for soot and creosote, and it’s easy to miss if you’re not looking for it. We see clogged tees often in Alpharetta wood-burning fireplaces, sometimes cutting draft by half before the homeowner notices any problem.
- Rain cap failures above older masonry chimneys. In Alpharetta’s Windward and Crabapple neighborhoods, many original terra cotta flues have been relined with DuraFlex, but the older masonry chimneys often still lack a proper rain cap. Humid air and rainwater dripping onto the liner accelerate creosote glazing and corrosion. We install custom caps sized to the flue, not generic hardware-store fixes.
DuraFlex Service in Alpharetta: What Local Conditions Mean for Your Equipment
Alpharetta sits in a humidity pocket that changes how creosote behaves inside a DuraFlex liner. In drier climates, creosote forms as a flaky, dry deposit that brushes off fairly easily. Here, the moisture in the air keeps creosote at a sticky, tar-like consistency for months. That sticky creosote clings to the corrugated ridges of a DuraFlex 316L liner and literally glazes over, forming a hard, glassy coating that a standard wire brush won’t remove. We see it every winter. Homes in Windward and Crabapple, where many original terra cotta flues were relined with DuraFlex but never got proper rain caps, have it worst. Moisture entering from above combines with humid air from below to cook creosote into a crust that requires rotary cleaning heads and, in some cases, chemical treatment to break down safely. If you own a DuraFlex liner in Alpharetta and you’re burning wood regularly, an annual sweep isn’t a suggestion. It’s the minimum.
We were called to a home in Crabapple for a Level 2 inspection after the homeowner noticed a smoky smell in the living room. Inside the chimney, we found a DuraFlex 316L liner with heavy creosote buildup in the corrugated ridges, plus a cracked terra cotta crown letting moisture drip onto the liner. Our crew brushed the liner thoroughly, repaired the crown with a waterproof coating, and installed a custom multi-flue cap to keep rain out. That stopped both the smell and the corrosion that was already starting on the liner surface. The homeowner didn’t need a new liner. They needed the existing one cleaned correctly and the chimney sealed against the humidity that was quietly wrecking it. That’s the difference between a sweep and a proper DuraFlex service call.
DuraFlex Models & Products We Service in Alpharetta
We service the full range of DuraFlex liner systems: the 316L Flexible Chimney Liner, the Pro Stainless Steel Liner, the Smooth Wall Liner, and the Hybrid Liner. Each has a distinct profile and a different creosote behavior pattern, and we don’t treat them all the same. The corrugated 316L is the most common liner we see in Alpharetta, and it demands the most aggressive brushing. The Smooth Wall and Pro lines shed creosote more readily but still need regular attention in humid conditions.
For repairs, we recommend genuine DuraFlex components. Knock-off stainless steel often lacks the alloy consistency of the real thing and can fail in a fraction of the time. If your liner is heavily corroded or kinked, we’ll usually recommend replacement over patchwork. Repairing one section of a compromised liner rarely restores safe draft, and you’d be paying for a fix that won’t hold. We stock common DuraFlex fittings and caps locally, which cuts turnaround time for Alpharetta jobs.

AfterDuraFlex Service Pricing in Alpharetta
A standard DuraFlex chimney cleaning in Alpharetta typically runs between $180 and $340, depending on liner condition, creosote volume, and whether we’re dealing with glazed deposits that need rotary cleaning. A Chimney Inspection in Alpharetta, which we recommend as a Level 2 check for any DuraFlex liner that hasn’t been camera-checked in the last two years, usually adds $150 to $400 depending on what we find and how accessible the flue is. Damper repair starts around $180 and goes up based on the parts and access.
What drives the cost is creosote density and liner condition. A lightly used fireplace with dry creosote is a fast sweep. A heavily glazed liner in a three-story Alpharetta chimney with a bad rain cap is a different job entirely. Every estimate includes a written price before any work starts, a camera inspection with photo documentation, and a full report of what we found. Nothing gets recommended without photographic evidence you can see yourself. Call (762) 600-1468 for an exact quote. Estimates are free.

FAQs – DuraFlex Chimney Cleaning in Alpharetta
Alpharetta’s high humidity keeps creosote sticky and dense, so it accumulates faster and glazes harder inside the corrugated ridges of a DuraFlex 316L liner than it would in a dry climate like Arizona or Colorado. The same burning habits produce more dangerous buildup here. Annual cleaning is the baseline, and heavy wood burners may need a mid-season check. Call (762) 600-1468 and we’ll inspect your specific liner and give you a real schedule, not a generic one.
You can attempt it, but we don’t recommend it. A store-bought brush often won’t reach the creosote packed into DuraFlex’s corrugated ridges, and without a camera inspection you won’t know what you missed. More importantly, a chimney sweep involves working at height and dealing with fine particulate that’s dangerous to breathe. The risk isn’t worth the $100 you’d save. If you want to see what’s actually in your flue, we’ll camera it for you and show you the footage.
Yes, if the liner is in good condition and the chimney above it is sealed properly. The concern in Crabapple and Windward is the older masonry: cracked crowns, missing rain caps, and spalling brick let moisture into the chimney cavity. That moisture accelerates corrosion on the DuraFlex liner and contributes to creosote glazing. We check both the liner and the masonry because one fails without the other. If you haven’t had a Level 2 inspection, start there.
A Level 2 inspection is a full camera sweep of the liner interior, from the firebox to the top of the flue, plus a visual check of the chimney exterior, crown, flashing, and cap. We document everything with photos and write up exactly what we found, what it means, and what it costs to fix. It’s the inspection we recommend for any DuraFlex liner that’s been in service more than two years without a camera check, or any chimney that’s changed hands recently. The cost depends on access and liner length, but you’ll have a written price before we start.
Tell me what’s in the flue, and I’ll tell you what it takes to fix it. The signs of a failing DuraFlex liner are usually subtle: a smoky smell that lingers after a fire, reduced draft, flaky stainless particles in the firebox, or visible rust staining on the chimney exterior. None of those definitively confirm liner failure without a camera, but all of them justify an inspection. Don’t wait for a chimney fire to be your diagnostic tool. Call (762) 600-1468 and we’ll get a camera in there.
