Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
DuraFlex Chimney Cap & Crown in Atlanta: What to Know First
We provide independent DuraFlex chimney cap and crown service across Atlanta, from Inman Park to Buckhead to Decatur, with most jobs completed in a single visit once parts are confirmed. A written price lands in your inbox before any work starts, and every job carries our 365-Day Done Right Promise under the Haven Standard. If you own a DuraFlex system and you’re seeing rust streaks, crown cracking, or a cap that’s lost its mesh tension, this page is for you. Call (470) 435-7984 to book a camera inspection and get your written estimate.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wrap) liner collars corrode at the cap interface. The 316Ti stainless wrap terminates in a collar that sits directly under the cap’s drip edge. In Atlanta’s humidity cycles, condensation pools where the collar meets the flue tile, and the galvanic reaction between dissimilar metals eats the collar lip in four to six years. We pull the cap, cut back the damaged collar, and install a DuraFlex-compatible stainless termination collar with a bead of high-temp silicone at the seam. The camera goes down after to confirm no debris dropped into the flue.
- DuraFlex Pro multi-flue caps lose mesh tension on south-facing exposures. The expanded stainless mesh on Pro-series caps is held by a crimped frame. Atlanta’s summer UV and thermal cycling fatigue the crimp, and by year five the mesh sags enough that squirrels can push through. We replace with a Gelco multi-flue cap using a welded mesh frame, or source OEM DuraFlex mesh inserts when the frame itself is sound. Corrine Halstead’s crew documents the sag measurement with a photo before quoting, so you see why replacement beats repair.
- DuraFlex DW (double-wall) air-cooled caps clog with pollen and cottonwood seed. The DW series pulls combustion air through the cap’s outer jacket, and Atlanta’s spring pollen load packs that airway solid by June. The cap overheats, the paint blisters, and the inner liner starts seeing flue gas temperatures it wasn’t designed for. We pull the cap, run a borescope through the air channel, and either deep-clean or replace depending on whether the inner baffle has warped. The camera doesn’t negotiate - it just shows you what’s there.
- DuraFlex crown coating delaminates on flat or negative-pitch crowns. DuraFlex’s factory crown coating is a cementitious slurry that needs positive drainage to survive freeze-thaw. Atlanta’s ice events are brief but sharp, and we see spalling on homes in Virginia-Highland and Candler Park where the crown was poured flat in the 1980s. We grind to sound concrete, re-pitch with a Portland-based crown mix, and apply a breathable siloxane sealer rather than re-coating with the same product that failed.
- DuraFlex flex liner termination caps separate at the hose-clamp joint. The flex-to-cap connection on DuraFlex liners uses a stainless hose clamp with a spot-welded screw housing. Vibration from wind across the flue, common on Atlanta’s ridgeline homes in Morningside, works the screw loose over two to three burning seasons. We replace the factory clamp with a constant-tension T-bolt clamp and safety-wire the assembly. It’s a fifteen-dollar part that prevents a thousand-dollar liner collapse.
Our DuraFlex Chimney Cap & Crown Process

- 1
Book the inspection. A live person answers (470) 435-7984, or you text us. We confirm your DuraFlex model if you know it, and we pull your home’s permit history if the system was installed with a city of Atlanta mechanical permit.
- 2
NFPA 211 Level 2 camera inspection. Our tech runs a Chim-Scan or equivalent down the flue, photographs the cap and crown from the roof and the firebox, and records a video of the flue interior. You get the footage same-day via email.
- 3
Written scope and price. Before any work starts, you receive a line-item quote: parts, labor, warranty terms, and what happens if we find additional damage once the cap is off. Haven Standard Clause 1 requires this in writing, and we don’t deviate.
- 4
Parts procurement. We source DuraFlex OEM through Haven’s buying network when the warranty or fit demands it; we quote quality aftermarket from Olympia Chimney or Famco when the OEM part is back-ordered or overpriced for the application. You see both options in writing.
- 5
Repair and test. The tech performs the cap or crown work, runs a smoke-pencil draft test, and sends a second camera pass to confirm flue integrity. The job isn’t closed until the draft reading is documented and the photo record is uploaded.
- 6
Cleanup and documentation. We haul scrap, leave the roof and hearth cleaner than we found them, and email your final packet: before/after photos, camera footage, written warranty, and the 365-Day Done Right Promise stamped and dated.

Why Atlanta Homeowners Call Level Two Chimney Atlanta for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of Atlanta’s inventory runs DuraFlex liners and caps from the 2015-2020 installation boom. Our techs know the difference between a SW collar and a DW termination without checking the manual, and we stock the common failure parts so you’re not waiting three weeks for a back-ordered clamp. When DuraFlex OEM is the right call, we source it through Haven’s buying network at prices that reflect our volume, not retail markup. When HeatShield or Gelco makes more sense for your cap or crown application, we say so plainly and document why. The 365-Day Done Right Promise applies to every job, and Clause 4 of the Haven Standard means your photo record is archived and accessible if you sell the home or need warranty follow-up. We’re independently owned and operated - not a franchise, not a DuraFlex affiliate - and our license number is on every page and every truck.
FAQs
DuraFlex’s limited lifetime warranty covers manufacturing defects in the liner itself, but caps and crowns are wear items excluded after the initial install period. We handle warranty paperwork for manufacturing defects we can document with our camera footage, but most cap and crown failures we see in Atlanta are environmental, not defective. Call (470) 435-7984 and we’ll inspect before you spend time on a claim that won’t pay.
We stock the five most common DuraFlex termination components at our Decatur warehouse, and Haven’s buying network delivers non-stock OEM parts in three to five business days. For urgent jobs, we carry quality aftermarket caps from Gelco and Famco that fit DuraFlex terminations without adapter kits, and we note the warranty trade-off in your written scope. You’ll know exactly what you’re getting before anyone climbs the ladder.
Repair makes sense when the crown damage is superficial spalling under 3/8 inch deep and the cap frame, mesh, and liner connection are sound. We replace the assembly when the crown has lost structural integrity, the cap mesh is breached, or the liner termination shows corrosion that compromises the flue seal. Our camera inspection shows you which category you’re in, with photos, and the written quote breaks out both paths if either is viable.
Most cap replacements and crown repairs run two to four hours on site once parts are in hand. Crown coatings need 24-hour cure time before the flue is fired, so we schedule those for mornings when possible. We don’t promise same-day dispatch, but we do keep common DuraFlex caps in stock for next-business-day scheduling once your inspection is complete.
Water enters through a failed cap or cracked crown, saturates the insulation wrap on DuraFlex liners, and accelerates corrosion of the outer jacket from the outside in. We’ve pulled DuraFlex liners in Atlanta’s Grant Park and Old Fourth Ward that looked fine from the firebox but were perforated above the roofline where water had pooled for seasons. A camera inspection catches this before the liner fails and you’re looking at a full replacement. The inspection is free - call (470) 435-7984 to book.
