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 Sweep in Marietta: What to Know First
We provide independent HeatShield chimney sweep in Marietta with a written price before any work starts and a camera-scan inspection included on every visit. Most HeatShield liner jobs in Cobb County run $280-$520 for a standard sweep and Level 2 inspection, with scheduling typically available within 3-5 business days during non-peak months. This page is for Marietta homeowners with a HeatShield flue liner, cast-in-place system, or refractory seal who need cleaning, inspection, or repair - and want to know what it costs before a truck rolls.
Call us at (470) 288-2763 for a free estimate. Corrine Halstead and our team have cleaned and inspected HeatShield systems across Marietta since 2009, from newer installs in East Cobb to older cast-in-place jobs in the Whitlock Avenue corridor where freeze-thaw cycles hit hard.
How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Flue Liner: thermal shock cracking at the smoke chamber junction. The cerfractory blend expands and contracts differently than surrounding masonry. In Marietta, we see this most on north-facing chimneys where temperature swings are sharpest. We map the crack with a camera, then resurface with HeatShield’s factory-matched cerfractory slurry or recommend a partial reline if the damage exceeds 25% of the surface area.
- HeatShield Cast-In-Place System: delamination from moisture intrusion behind the liner. This shows up as a hollow sound when we tap the flue wall, or as flakes in the soot pile during sweeping. The cause is almost always a failed crown or missing cap letting water sit behind the cast layer. We clean the flue, locate the breach with a camera, and repair the crown or cap before touching the liner - otherwise the delamination returns within two seasons.
- HeatShield Joint Repair (Resurfacing System): premature wear at offset flue joints. Older Marietta homes with shifted clay flue tiles often get a HeatShield resurfacing to bridge the gaps. The weak point is the offset itself, where creosote accumulates in a ridge and the resurfacing material wears thin. We pull the camera back to measure the remaining thickness, then spot-repair with OEM HeatShield slurry or recommend a full cerfractory liner if the offset exceeds 1/2 inch.
- HeatShield Smoke Chamber Repair: slurry failure from improper original application. We find this in DIY or cut-rate installs where the surface wasn’t properly scarified first. The slurry separates in sheets during routine sweeping. Our fix is removal of the failed material, mechanical scarification with a needle gun, and reapplication to factory spec - documented with before-and-after photos under Haven Standard Clause 4.
- HeatShield Refractory Seal: spalling from sulfuric acid condensation. Gas appliances with marginal draft produce acidic moisture that eats the seal surface. We detect this as a chalky, pitted texture during camera inspection. The repair is a full reseal with HeatShield’s gas-rated formulation, plus draft testing to confirm the root cause is solved. We won’t reseal without that test - it’s a waste of your money.
Our HeatShield Chimney Sweep Process
- 1
Call and schedule. A live person answers, 24/7. We ask the appliance type, fuel, last service date, and any symptoms. We quote a flat inspection fee over the phone - no surprises.
- 2
Camera-first inspection. Our tech arrives in uniform, license visible, and runs a Level 2 camera scan before touching a brush. We document liner condition, creosote class, and any HeatShield-specific wear. Camera first, quote second, work third - in that order, every time.
- 3
Written price and scope. You get a single-page document with findings, recommended work, parts specified (OEM HeatShield or quality aftermarket from our Haven buying network), and total cost. No work starts until you sign.
- 4
Sweep and repair. We use rotary brushes sized to your HeatShield liner diameter, HEPA containment, and drop cloths. Repairs use factory-specified materials sourced through our DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield supply chain.
- 5
Post-work testing and documentation. We run a final camera pass, draft test where applicable, and compile your photo record. Haven Standard Clause 4 requires this archive - you get a copy, we keep a backup.
- 6
365-Day Done Right Promise. If anything in our scope fails, we return and make it right. The promise is stamped on every job record.

FAQs
No, professional cleaning by a qualified chimney sweep does not void a HeatShield warranty, but using wire brushes or improper tools can damage the surface and void coverage. We use rotary poly brushes sized to your liner diameter and document the method in your photo record. If your system is still under original warranty, we note the serial number and installation date in our report to protect your claim. Call (470) 288-2763 if you need help locating your warranty paperwork.
HeatShield cerfractory slurry requires 24-48 hours of no-fire curing time, depending on ambient temperature and humidity. In Marietta’s spring and fall, we schedule 36 hours minimum; summer humidity can push this to 48. We build this into your appointment timing and mark the safe restart date on your written completion document. Plan your burning season accordingly - we see a rush every October from homeowners who waited too long.
We stock HeatShield-compatible materials through our Haven buying network and can match spec on most repairs without factory delays. For warranty claims requiring genuine HeatShield serial-numbered components, we order direct and keep you informed on lead time. We never substitute without your written approval - that’s Haven Standard Clause 1. Call for current availability on your specific system.
The camera tells the story. Cracks under 1/8 inch in a single location typically qualify for spot repair; multiple cracks, delamination over 25% of surface area, or exposed substrate means reline. We show you the footage, measure the damage, and explain both options with prices before you decide. No camera evidence, no recommendation - that’s our rule. Call (470) 288-2763 to schedule the inspection.
NFPA 211 recommends annual inspection for all chimney systems, and sweeping when creosote exceeds 1/8 inch. In Marietta, oak and hickory - our most common firewood - produce Class II creosote that typically needs removal every 1-2 cord-burning seasons. Gas-fired HeatShield systems need less frequent sweeping but still require annual inspection for condensation damage, which we see more often than most homeowners expect. Call (470) 288-2763 to set a schedule based on your fuel and usage.
