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.

AfterDuraFlex Chimney Liner & Rebuild in Alpharetta: What to Know First
We provide independent DuraFlex chimney liner and rebuild service across Alpharetta, typically scheduling within a week and completing most liner replacements in one day. Every job starts with a written price, a camera-scan inspection, and a documented photo record before any work begins. If you own a DuraFlex liner and are seeing rust flakes in your firebox, draft problems, or a chimney professional has told you the liner needs replacement, call us at (678) 679-0171 for a free estimate with no obligation to book.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless smooth-wall) develops circumferential cracking near the top third of the flue. The 316Ti alloy handles Alpharetta’s humidity swings well, but the expansion joint at the top plate takes stress from summer heat buildup in brick enclosures with poor ventilation. We cut back to sound metal, install a custom-fabricated top assembly with an improved expansion joint, and document the weld with photos.
- DuraFlex AL (aluminum) liners in gas applications suffer bottom-end corrosion from condensate pooling. Aluminum doesn’t tolerate the acidic condensate produced by high-efficiency furnaces when the slope is less than optimal. We replace the damaged lower section with AL-compatible DuraFlex or transition to 316Ti stainless if the appliance mix has changed, always verifying the new slope drains properly.
- DuraFlex Pro and ProXL flexible liners show mortar-joint impressions that progress to actual tears. These heavy-wall liners are built for abuse, but in Alpharetta’s older masonry chimneys with offset flues, the repeated flexing around sharp offsets work-hardens the corrugation. We sleeve with a smooth-wall DuraFlex SW insert or rebuild the offset with a poured smoke chamber to eliminate the abrasion point.
- Top termination corrosion on DuraFlex installations with aftermarket caps. The DuraFlex top plate is designed for specific clearances; an oversized decorative cap traps moisture against the 316Ti collar. We source the correct DuraFlex termination or fabricate a ventilated replacement, and we document the clearance with a photo measurement for your record.
- Multi-story pulls where the original DuraFlex liner was field-cut too short. The resulting gap at the thimble or appliance collar leaks combustion gases into the wall cavity. We don’t patch this with foil tape; we pull a correctly sized replacement and install a proper adapter, with a smoke-pencil test to confirm the seal.
Our DuraFlex Chimney Liner & Rebuild Process
- 1
Camera-scan inspection (NFPA 211 Level 2). We run the camera the full flue length, identify the DuraFlex series and failure mode, and show you the footage on site. The camera doesn’t soften anything, and neither do I.
- 2
Written scope and price. Before any work starts, you receive a written description of what we found, what we’ll do, what parts we’ll use, and the exact price. Clause 1 of the Haven Standard requires it.
- 3
Parts decision: OEM DuraFlex or quality aftermarket. We stock common DuraFlex diameters and source through Haven’s buying network. If your job needs a custom fabrication or a faster turnaround, we’ll explain the aftermarket option and any warranty implications.
- 4
Installation or rebuild. For liner replacement, we pull the new DuraFlex with proper tension, secure the top termination, and seal the bottom adapter. For rebuilds, we reconstruct the chimney structure to factory specifications for liner support.
- 5
Smoke test and documentation. We verify draft and leakage with a smoke pencil, then deliver your photo record and written warranty. Clause 4 of the Haven Standard requires the documented record; we’ve done this on every job since 2009.
- 6
365-Day Done Right Promise follow-up. If anything isn’t performing as specified, we return and make it right. The promise is stamped on every job.

Why Alpharetta Homeowners Call Emberly Chimney Cleaners Alpharetta for DuraFlex Work
Corrine Halstead and her crew have worked chimneys across Alpharetta long enough to recognize which builder installed which liner when, and what typically fails first. We’ve pulled DuraFlex liners from homes off Webb Bridge Road near Wills Park and from newer construction throughout the city, and we know the local permit requirements for liner replacement in Fulton County.
Our technicians are background-checked and uniformed; you’ll get a text when yours is on the way with a name and photo. If your DuraFlex job also needs HeatShield cerfractory sealant for a smoke chamber or a Gelco cap for the termination, we carry those materials too - procured through Haven’s buying network to keep pricing honest. Every job includes the camera-scan inspection, written price, documented photo record, and the 365-Day Done Right Promise. Bring us any competitor’s written estimate for a free second opinion.
FAQs
No, proper repair by a qualified chimney professional does not void DuraFlex’s warranty, but using non-compatible parts or improper installation methods can. As an independent DuraFlex service provider, we use OEM DuraFlex components or document-equivalent aftermarket parts so your warranty remains intact. If warranty coverage matters for your situation, tell us when you call (678) 679-0171 and we’ll specify OEM-only on your written scope.
The camera footage decides: isolated damage to a section, such as a cracked top plate or corroded bottom adapter, often permits partial replacement. Multiple cracks, thinning wall sections, or delamination of the corrugated wall mean full replacement. We show you both options with prices for each when the difference matters. Call (678) 679-0171 for the inspection and a written recommendation.
Most single-story DuraFlex liner replacements in Alpharetta are completed in one working day. Two-story homes, tight flue offsets, or jobs requiring chimney structure repair may extend to two days. We book the time your job actually needs and confirm the schedule in writing before we start.
Yes. We stock common DuraFlex diameters and source through Haven’s buying network with direct relationships to suppliers. Uncommon sizes or custom fabrications typically arrive within three to five business days. We’ll tell you exactly what’s available and when before you book.
A damaged DuraFlex liner can leak combustion gases including carbon monoxide into your home, and gaps in the liner can allow creosote to contact combustible framing. The risk increases with use, not gradually but stepwise when a crack propagates or a corrosion hole opens. We don’t use scare tactics; we show you the camera footage and let you decide based on what you see. Call (678) 679-0171 for a free estimate.
