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.

Cherry Hill was built almost entirely during a single concentrated suburban boom in the 1960s and 1970s, triggered by the 1961 opening of Cherry Hill Mall and rapid Philadelphia-area flight to Camden County suburbs. That means the township has an unusually dense concentration of similarly-aged masonry chimneys, most now 50-60 years old and hitting the same critical deterioration window simultaneously. A large share of those homes later converted from oil-fired furnaces to natural gas without relining the chimney, leaving original terra cotta flue tiles sized for high-temperature oil exhaust now venting cooler gas appliances - a pattern we also see in Heatshield repair in Camden. The result is condensation, acidic byproduct buildup, and accelerated liner failure - exactly the conditions that sent many Cherry Hill homeowners toward HeatShield Cerfractos resurfacing in the first place.
We know these chimneys. Russell Haines, our owner, has worked them for years, including older colonials over in the Barclay Farm neighborhood where the fireplaces run nearly as old as the subdivision itself. The chimney either draws the way it should, or it does not - and we will not leave until we know which.
Why Trust Hearthstone Chimney Co. for Your HeatShield Chimney Cleaning?
HeatShield products are proprietary. The Cerfractos silicate-ceramic armor and TherMix insulative parge coat use heat-cure chemistry that does not bond correctly with generic refractory cement. We stock genuine HeatShield materials for resurfacing and parge work, and our technicians understand the difference between a liner that needs re-coating and one that needs replacement with stainless steel or a full rebuild.
Russell Haines picked up his trade fundamentals at Los Angeles Trade-Technical College before spending the better part of two decades working chimneys up and down the East Coast. That background shows in how we diagnose. A Level 2 camera inspection ends with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. We do not tell you a liner is failed unless we can show you the delamination, the joint crack, or the condensate damage on camera.
Our independence matters here. Because we are not a HeatShield dealer with manufacturer quotas, we can tell you when your Cerfractos armor still has serviceable life left. We can also tell you when patching is throwing good money after bad. The 90-Day Done Right Promise backs either call - in writing, no arguing.
Every technician is background-checked and uniformed. Most jobs finish in a single visit. A live person answers the phone 24 hours a day, 7 days a week - not a voicemail, not a callback queue.
Common HeatShield Chimney Cleaning Problems We Fix in Cherry Hill
- Cerfractos armor delamination from gas-log condensate. HeatShield Cerfractos was designed to handle the temperatures of wood-burning and oil-fired flues. In Cherry Hill, we regularly see it installed behind gas log sets or high-efficiency inserts that run cooler than the liner was rated for. The result is acidic flue-gas condensate that slowly separates the ceramic armor from the terra-cotta tile face. It looks intact from the firebox. A Level 2 camera reveals the gap.
- TherMix parge coat cracking at fractured tile joints. The insulative parge coat goes on over Cerfractos to meet modern flue-sizing and insulation requirements. But if the underlying terra cotta was already fractured - common in Cherry Hill’s 1960s chimneys after decades of freeze-thaw - the coating hides the break. The surface looks smooth. The tile behind it is moving. We find this with camera inspection and tapping, not guesswork.
- Crown and cap damage softening the ceramic surface. Cherry Hill’s nor’easters drive wind-driven rain into chimney crowns that have never been replaced since original construction. Bulk water sitting against the heat-cured ceramic surface causes the armor to soften. Come winter, the freeze-thaw cycle spalls the tile behind it. We waterproof crowns and caps as part of HeatShield maintenance - not as an upsell, but because the liner will fail again if water keeps getting in.
- HeatShield resurfacing over structurally unsound tile. A previous contractor may have applied the Resurfacing System to a flue that was already compromised. The ceramic shell looks intact from below. Sweeping with a poly brush can fracture it loose. We inspect first, sweep second, and we use hand tools on questionable liners rather than power brushes that tear away the armor.
- Dual-flue cross-contamination in split-level and ranch chimneys. Cherry Hill’s tract developments are full of single-wythe brick chimneys with clay tile liners serving both a living room fireplace and a basement mechanical-room flue in the same chase. If one flue was resurfaced with HeatShield and the other was not, or if the divider tile has failed, flue gases can cross between them. Our camera inspection checks the divider wall and both flue paths.
HeatShield Parts & Our Repair-vs-Replace Approach
HeatShield’s Cerfractos and TherMix products are proprietary formulations. We stock genuine HeatShield materials for resurfacing and parge work rather than generic refractory cement that will not match the heat-cure chemistry or expansion rate. For fast turnaround on Cherry Hill jobs, we keep Cerfractos resurfacing compound, TherMix insulating mix, and compatible primers on hand.
When we find a failed liner, we assess honestly. Re-patch with HeatShield if the tile structure is sound and the delamination is limited. Move to stainless steel - DuraFlex is our preferred line - if the tile is fractured throughout or the flue is improperly sized for the appliance. Quote a rebuild if the chimney structure itself is compromised. Every recommendation comes with camera evidence you can see. Nothing is pushed without documentation.
Call (856) 543-2929 and we will walk you through what we found and what it actually costs.
Our HeatShield Service Process - Step by Step
- 1
Diagnosis with Level 2 camera inspection. We run a camera the full length of your HeatShield-lined flue, documenting armor condition, joint integrity, and any delamination. You get the photos and a plain-English verdict. In Cherry Hill’s older neighborhoods like Erlton and the streets just off Route 70, we often find oil-to-gas conversions with no relining work - the oversized clay tile flue venting a modern 80% furnace at temperatures too low to prevent condensate buildup.
- 2
Targeted cleaning with HeatShield-safe tools. We hand-sweep glazed creosote with poly brushes on questionable Cerfractos armor to avoid tearing loose sections. HEPA vacuum controls soot in the firebox. If the liner is sound, we use appropriate brushes for the coating type.
- 3
Repair or resurfacing with genuine HeatShield materials. Re-patch delaminated sections with Cerfractos compound, apply TherMix where insulation value is needed, or address crown and cap leaks with waterproofing. We do not use generic substitutes.
- 4
Post-repair camera verification and draft test. We camera the flue again after any resurfacing work to confirm full coverage and proper cure. Draft testing confirms the flue draws correctly for your appliance type - wood, gas, or oil.
- 5
Documentation and 90-Day Done Right Promise. You receive photos, a written report, and our guarantee in writing. If it is not right, we come back. No paperwork to file, no argument.
HeatShield Products We Service & Install in Cherry Hill
We work with the full HeatShield residential line:
- HeatShield Cerfractos - silicate-ceramic armoured flue liner, the most common HeatShield product in Cherry Hill’s 1950s-1980s masonry chimneys
- HeatShield TherMix - insulative parge coat applied over Cerfractos to meet modern flue-sizing and NFPA 211 insulation requirements
- HeatShield Resurfacing System - applied directly to terra-cotta flue tiles, single-flue or multi-flue, as an alternative to full stainless relining when tile structure is sound
We stock Cerfractos resurfacing compound, TherMix insulating mix, and compatible primers locally for Cherry Hill jobs. Most resurfacing work completes in one visit. Full relines with DuraFlex or Gelco stainless liners are quoted separately when HeatShield repair is not the right answer.
We Also Service These Brands
Hearthstone Chimney Co. is not a single-brand shop. We install and service DuraFlex stainless chimney liners, Gelco chimney caps and accessories, and work with Olympia Chimney, Famco, and Copperfield products where they fit the job. Our technicians carry the training and parts to handle mixed-brand systems, which matters when your HeatShield liner needs a DuraFlex replacement or a Gelco cap to keep water out.
FAQs - HeatShield Chimney Cleaning Service in Cherry Hill
No. We are an independent HeatShield service provider, not affiliated with or authorized by the manufacturer. That independence means we assess your liner based on its actual condition, not on warranty quotas or dealer incentives. We use genuine HeatShield materials for repairs, but we make our own calls on whether repair or replacement serves you better.
Yes, with the right technique. We inspect first with a Level 2 camera to locate any delaminated or loose sections. Where the armor is questionable, we hand-sweep with poly brushes rather than power-driven steel or stiff poly that can catch and tear the ceramic surface. A Cerfractos flue in good condition handles standard sweeping. One with hidden delamination does not - and we find the difference before we touch it.
Not necessarily. TherMix parge coat cracking at tile joints often means the underlying terra cotta was already fractured, and the coating is telegraphing that movement. We camera-inspect to see if the tile itself is structurally sound. If it is, re-coating with TherMix may be the right fix. If the tile is shifting or broken through, the liner needs more than surface repair. We show you the camera footage and quote both paths when both are viable.
The schedule is the same - annually for wood-burning, per manufacturer spec for gas - but the technique differs. A HeatShield Resurfacing System creates a smooth, jointless surface that actually sheds creosote better than rough terra cotta, as we explain in our Chimney Cleaning & Sweep services. But if the resurfacing was done over compromised tile, the shell can fracture under aggressive brushing. We adjust our approach based on camera findings each year. Call (856) 543-2929 to schedule your inspection.
Yes, and we pay particular attention to the condensate issue. Gas log sets run cooler than wood fires, and in Cherry Hill’s converted oil-to-gas chimneys, that cool exhaust hits an oversized flue and creates acidic condensate. That condensate is what delaminates Cerfractos armor over time. We check for that damage during every gas-appliance sweep, and we document it with photos.
Yes. Crown and cap waterproofing protects the HeatShield liner by keeping bulk water out of the chimney structure. We use vapor-permeable sealers that let the masonry breathe while blocking liquid water. The liner itself is not exposed to the waterproofing product. In fact, we often recommend crown work alongside HeatShield repairs because water entry is a leading cause of ceramic armor softening and winter spall damage.
A standard sweep and Level 2 inspection for a HeatShield-lined chimney in Cherry Hill typically runs $180-$340. Cerfractos resurfacing or TherMix parge work ranges from $1,200-$2,800 depending on flue height, accessibility, and how much tile prep is needed. Full stainless relining with DuraFlex is quoted separately when HeatShield repair is not viable. We provide no-hassle upfront pricing - the number on the estimate is the number on the invoice. Call (856) 543-2929 for an exact quote; estimates are free.
We cannot guarantee warranty status because we are not an authorized HeatShield dealer. What we can guarantee is that we use genuine HeatShield materials and follow manufacturer-compatible installation practices. If your liner is still under original warranty, you may want to contact HeatShield directly before authorizing independent service. We will tell you honestly if we see signs that previous work may have already compromised warranty coverage.
