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.

AfterHeatShield Chimney Cap & Crown in Alpharetta: What to Know First
We provide independent HeatShield chimney cap and crown service in Alpharetta, typically scheduling within 3-5 business days and completing most jobs in a single visit. Every repair starts with a camera-scan inspection and ends with a written warranty, a photo record, and a price you knew before we touched a tool. As an independent HeatShield service provider, we stock OEM and quality aftermarket parts for the Cerfractory Flue Seal, Joint Repair, and Resurfacing Systems, plus the full HeatShield cap and crown line. If your HeatShield cap is rusting through at the mesh, your crown coating is alligatoring after five Alpharetta freeze-thaw cycles, or you’re not sure what you have, call us at (678) 679-0171. We’ll send a named tech, text you when they’re en route, and quote the work in writing before anything starts.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Seal cap bases crack at the flue collar weld. The 304 stainless collar on early Cerfractory Seal caps work-hardens where it meets the cast refractory base, especially on homes north of Windward Parkway where afternoon sun hits metal at 140°F while interior flue temps swing from ambient to 400°F. We cut the collar, weld in a flex section, or replace with the updated Cerfractory Plus base that carries a wider thermal expansion joint.
- HeatShield mesh screens clog with cottonwood and pine pollen. The 5/8-inch mesh on standard HeatShield caps is correct for ember containment, but Alpharetta’s April-May pollen load mats the screen and chokes draft. We pull the screen, document the blockage with photos, and either clean and reinstall or upsize to a Gelco 3/4-inch mesh where code allows, noting the change on your written record.
- Crown Resurfacing alligators or delaminates within 3-5 years. HeatShield’s CrownCoat applies at 1/8-inch and relies on substrate prep most crews skip. In Alpharetta, the clay cap beneath absorbs monsoon-season moisture through hairline cracks; freeze expansion pops the coating. We grind to sound concrete, apply a bonding agent, then trowel CrownCoat in two lifts with a mesh reinforcement strip at the flue interface.
- Multi-flue cap sidewalls bow from thermal cycling. HeatShield’s multi-flue caps use 24-gauge stainless on spans over 36 inches. On larger Alpharetta homes off Webb Bridge Road with 48-inch+ chimney masses, the sidewalls oil-can in and out until fasteners wallow. We sister in angle stock or spec a heavier-gauge DuraFlex equivalent, transferring the HeatShield mounting pattern so you don’t redrill the crown.
- Joint Repair mortar washes out at the crown-flue joint. HeatShield’s refractory mortar sets hard and strong, but the 3/4-inch expansion gap it bridges on older systems can’t handle Alpharetta’s clay-soil settlement. We open the joint to 1-1/2 inches, pack with ceramic blanket, and cap with a floating seal that moves without cracking.
Our HeatShield Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, checks HeatShield parts availability, and books a two-hour window. You get a text with your tech’s name and photo the morning of.
- 2
Camera-scan inspection. We run the chimney camera per NFPA 211 Level 2, Clause 4 of the Haven Standard. The camera doesn’t soften anything, and neither do I. You see the flue, the crown interior, and the cap mounting condition on a tablet before we quote.
- 3
Written price and scope. We deliver a single-page quote: parts (OEM HeatShield or approved equivalent), labor, warranty term, and what happens if we find additional damage. No work starts until you sign.
- 4
Repair and test. We pull the old cap, prep the crown, install or coat, and run a draft test with a manometer. Smoke chamber, flue, and cap interface are photographed.
- 5
Documentation and cleanup. You receive a printed photo record, the signed warranty, and a digital copy by email. We haul away scrap. Payment is due on completion.
- 6
365-Day Done Right Promise. If the cap leaks, the coating cracks, or the draft drops, we return and make it right. That’s Haven Standard Clause 5.

Why Alpharetta Homeowners Call Emberly Chimney Cleaners Alpharetta for HeatShield Work
We’ve worked Alpharetta chimneys long enough to know which builders spec’d HeatShield in the 2015-2020 build wave and where the shortcuts show up. Corrine Halstead and our crew have done cap and crown jobs off Webb Bridge Road near Wills Park, in the Windward subdivisions, and across the newer developments north of GA-400. When a HeatShield part is backordered, we source equivalent DuraFlex or Gelco components through our Haven buying network rather than leave you exposed through burning season. Every tech is background-checked, uniformed, and carries a license number you can verify. The photo record, the written price, and the 365-Day Done Right Promise are not extras. They’re Clause 1 and Clause 4 of the Haven Standard, and they’ve been standard here since 2009.
FAQs
No, if the work uses OEM parts or equivalent and doesn’t alter the flue system. As an independent HeatShield service provider, we document parts serial numbers and installation methods so any future warranty claim has a clear paper trail. We don’t guess at compatibility. Call (678) 679-0171 and we’ll verify your cap model against current OEM specs before we quote.
A properly applied HeatShield CrownCoat lasts 10-15 years in Alpharetta, but the prep work determines everything. The 25-30 annual freeze-thaw cycles here, combined with clay-crown moisture absorption, destroy coatings applied over dirty or damp substrate in 3-5 years. We grind, bond, and reinforce per manufacturer spec, then photograph each layer. If you’re quoted a CrownCoat job without surface prep in the scope, get a second opinion. Ours is free.
Most common HeatShield caps and CrownCoat kits ship to our Alpharetta warehouse within 2-3 business days. For obsolete series, we cross-reference DuraFlex and Gelco equivalents from our Haven network and quote both options in writing. We don’t leave a flue open while waiting on a backorder. Call (678) 679-0171 and we’ll confirm availability for your specific model before booking.
Replace it if the stainless body is perforated, the mesh is separating at the weld, or the mounting flange is cracked. Repair is viable for clogged screens, loose fasteners, or minor flashing separation. We make the call with the camera footage in front of you, explain the difference in expected service life, and quote both paths if either is reasonable. No replacement gets sold on speculation.
Every 12 months, per NFPA 211, or after any severe weather event. Alpharetta’s March hail and summer wind shear dent caps and loosen fasteners more often than homeowners notice. Our annual sweep includes cap condition in the Level 2 camera scan. Skip the inspection and you’re gambling that pollen, rust, or a bent lid hasn’t compromised draft or spark containment. The camera finds what you can’t see from the ground.
