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 Cleaning & Sweep in Ewing: What to Know First
We provide independent HeatShield chimney cleaning and sweep services in Ewing, with most jobs completed in a single visit and upfront pricing agreed before we start. A standard HeatShield system inspection and sweep runs $89-$240 depending on access and condition, and we do not recommend work you cannot see for yourself on camera. This page is for Ewing homeowners who have a HeatShield liner, crown coating, or refractory product installed and need it cleaned, inspected, or checked before burning season. Call (856) 388-5580 - a live person answers, 24 hours a day.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Flue Sealant (CFS) liner coating cracks in freeze-thaw cycles. Ewing sits in the transition zone between coastal moisture and inland cold snaps. Water gets behind the CFS layer, freezes, and spiders the surface. We see this most in homes near the Delaware River basin where humidity lingers. We camera-map the crack pattern, remove loose material with rotary tools sized for HeatShield’s 5/16″ nominal thickness, and reapply only where the substrate is sound. If the underlying terra cotta is spalled, we tell you plainly - no coating hides that.
- HeatShield ProLiner corrugated sleeves separate at the overlap seams. The ProLiner’s interlock joint relies on tension fit and refractory bonding. After a decade of Ewing heating cycles, the corrugations fatigue and the seam gaps open. Our crew spots this with a forward-view camera before the sweep, because brushing a separated ProLiner can wedge creosote into the gap and make the repair worse. We mark the seam location, clean above and below separately, then re-secure or replace the section with OEM-compatible sleeve stock.
- Joint Repair (JR) mortar degrades from improper original mix ratios. Some Ewing installations from the 2008-2014 period used batch-mixed JR that was too wet for our climate’s cure rate. The result is a crumbly, porous surface that soaks up creosote and accelerates buildup. We test the JR hardness with a scratch pick during inspection. If it powders, we remove it to sound substrate and repack with fresh HeatShield JR mixed to the current spec - drier, packed harder, cured slower.
- Crown Coat (CC-100) alligatoring on south-facing Ewing exposures. The CC-100 acrylic-modified cement reflects UV well when new, but after 12-15 summers on a south or west pitch, surface checking lets water in. We find this during the Level 2 inspection when water staining appears on the exterior brick below the crown. Cleaning the flue first prevents debris from contaminating the crown repair. We grind the checked areas, prime with HeatShield’s specified bonding agent, and reapply CC-100 in two thin lifts - never one thick coat that traps moisture.
- Factory-built metal chimney chase covers with HeatShield inserts rust at the collar. Not a HeatShield product failure per se, but we see it paired often in Ewing’s 1980s-1990s split-levels near Parkway View. The chase cover is galvanized or cheap aluminum; the HeatShield insert is fine, but the collar seal fails and water runs down onto the refractory top. We document the rust with photos, clean the flue, and replace the chase cover with a proper stainless unit from Olympia Chimney or Famco - not another galvanized piece that fails in five years.
Our HeatShield Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, 24/7. We ask the HeatShield product line if you know it, the installation year, and any symptoms. We quote the inspection fee upfront - $89 for the Seasonal Tune-Up if no repair is needed.
- 2
Level 2 camera inspection on arrival. Our technician runs a forward-view camera the full flue length before touching a brush. We photograph every HeatShield seam, crack, and interface. You see the screen. We explain what we see in plain English.
- 3
Cleaning protocol matched to the product. CFS coatings get soft poly brushes, not steel. ProLiner sleeves get sectional rods with controlled torque. JR mortar joints get hand tools to avoid fracture. We collect debris in a HEPA vac - no mess in your Ewing home.
- 4
Parts decision with options. If we find damage, we show you the photo and explain OEM HeatShield versus quality aftermarket alternatives from our stock. No recommendation without evidence you can see.
- 5
Repair, test, and document. We complete most repairs in the same visit. Afterward, we smoke-test or draft-test the assembly. You get photos, a written condition report, and the 90-Day Done Right Promise in writing - no arguing, no paperwork chase.
- 6
Cleanup and final walkthrough. We leave the work area as we found it. The technician reviews the report with you, notes any maintenance timing, and schedules follow-up if needed.

FAQs
No - the original HeatShield warranty covers manufacturing defects and is not contingent on using a specific service network. We document our work with photos and written reports, which actually strengthens any future warranty claim by establishing maintenance history. Keep your records. If you have questions about a specific warranty term, we review it with you during the inspection. Call (856) 388-5580 to schedule.
You know after a Level 2 camera inspection. We run the camera before brushing, show you the footage, and explain whether what we see is surface staining, minor checking that can be monitored, or active damage that needs addressing. If the flue is right, the fire takes care of itself. If it’s not right, we tell you exactly why and show you the evidence. Estimates are free - call (856) 388-5580.
We stock and can order OEM HeatShield materials - CFS, JR, ProLiner sleeves, CC-100. We also carry compatible professional-grade alternatives from DuraFlex and Gelco. We recommend based on what your system needs, not what we have in the truck. You’ll see the part and the price before we start.
Once per burning season for wood-burning systems, per NFPA 211. Gas systems with HeatShield inserts get a Level 1 inspection annually and cleaning as needed. Ewing’s mixed hardwoods - oak and maple common in the area - burn cleaner than softwoods but still produce creosote. If you burn more than three cords per winter, consider a mid-season check. Call (856) 388-5580 to book.
Creosote accumulates on any surface, including HeatShield’s refractory coatings. Once the layer exceeds 1/8 inch, it becomes a combustion hazard. HeatShield liners are rated for high temperatures, but they are not magic - sustained chimney fires damage any system. Carbon monoxide risk rises if creosote or debris obstructs draft. The $89 Seasonal Tune-Up is cheaper than finding out the hard way. Call (856) 388-5580.
Ready to have your HeatShield system checked before burning season? Call (856) 388-5580 for a free estimate. A live person answers, 24 hours a day, 7 days a week. We’ll be there when we say - and we’ll show you exactly what we find.
