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.

Why Trust Hearthstone Chimney Co. for Your HeatShield Chimney Cleaning?
Russell Haines learned this trade hands-on through the building trades program at Los Angeles Trade-Technical College, then spent decades working chimneys before starting Hearthstone Chimney Co. in 1984. That background matters when you’re looking at a HeatShield system. We’ve installed, inspected, and repaired HeatShield chimney lining systems across hundreds of Lehigh Valley homes, and we’ve watched how cerfractory sealant and stainless liners respond to Easton’s specific conditions - the persistent valley fog from the Delaware-Lehigh confluence, the heavy freeze-thaw cycling, the moisture that finds every gap in aging mortar.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. We document like engineers, explain like craftsmen. If the flue is clear and the mortar is sound, that’s all the good news you need. When a HeatShield system needs attention, we source genuine HeatShield sealant and liner components when the original installation is intact, and we use UL-listed stainless liner and insulation equivalents only when the existing product has failed or been discontinued. We do not sell a full reline when a proper sweep, crown repair, and recoat will solve the problem. That’s a square deal: no surprises on the bill.
Our technicians are background-checked, uniformed, and complete most jobs in a single visit. A live person answers our phones 24 hours a day, 7 days a week - not a voicemail, not a callback queue.
Common HeatShield Chimney Cleaning Problems We Fix in Easton
- Cerfractory sealant flaking or delaminating at the flue crown. This is the most common HeatShield failure we see in Easton’s West Ward row homes. The original cerfractory coating was applied to a sound flue, but the chimney crown was never sealed afterward. Easton’s above-average ambient moisture and repeated winter freeze-thaw cycles let water migrate through the crown, saturate the top of the flue, and break the bond between sealant and masonry. The coating spalls in sheets. We find this during camera inspection, remove the loose material, repair or seal the crown, and recoat with HeatShield sealant.
- HeatShield stainless liner joints pulling apart or fasteners corroding. The HeatShield/UltraShield stainless-steel flue liner kits perform well when the chimney stays dry. But in Easton’s tightly packed row blocks, chronic water intrusion at the flashing - often hidden behind decades of patched siding - corrodes the fasteners and lets joints separate. Draft drops. Smoke spills. We camera the full liner run, identify the breach, and replace the damaged section with matching HeatShield-compatible components or UL-listed equivalents.
- Misapplied HeatShield sealant over a glazed or heavily creosoted flue. Some homeowners in Easton’s older colonials near the Delaware Canal inherited a “quick fix” where cerfractory sealant was sprayed over thick glazed creosote without proper cleaning first. The sealant never bonded to the masonry. It flakes off in chunks, sometimes blocking the flue. We remove the failed coating entirely, mechanically clean the glazed layer, and reapply HeatShield sealant only to a properly prepared surface. The difference shows on the next camera inspection.
- Liner sized too large for the appliance. Easton’s pre-1930 row homes have oversized coal-era masonry chimneys that were never properly relined when heating systems converted to gas or when fireplaces got modern inserts. A HeatShield liner installed without proper sizing creates a flue too large for the appliance’s exhaust volume. Gases cool prematurely. Draft weakens. Creosote collects at the seams and around the HeatShield surface. We measure the appliance output against the flue volume, then resize or replace with a properly matched HeatShield stainless liner.
- Moisture trapped in abandoned flues damaging adjacent active HeatShield liners. In West Ward row blocks, previous owners often bricked over abandoned coal-furnace flues without caps. Moisture and debris accumulate for decades inside the sealed stack. The saturated masonry transfers that moisture to adjacent active flues, accelerating HeatShield sealant deterioration from the outside in. Only a camera sweep reveals the hidden structural void and explains why the active flue is drafting poorly. We open the abandoned flue, clear the debris, cap it properly, and address the damaged HeatShield lining.
HeatShield Parts & Our Repair-vs-Replace Approach
We stock genuine HeatShield cerfractory sealant, primer, and crown repair materials on our Easton-area trucks, along with HeatShield-compatible stainless liner components and insulation blankets. For most HeatShield systems, we can complete cleaning, spot repair, and recoat work in a single visit.
Our rule is simple: if the existing HeatShield product is intact and the damage is localized, we repair. We clean the flue, remove only the failed material, fix the underlying water intrusion, and recoat. If the liner is corroded through, improperly sized, or discontinued, we replace with genuine HeatShield or UL-listed equivalents and tell you exactly why before we start. No full reline sold for a problem a sweep and recoat will fix. Call (610) 756-1504 for an honest assessment.
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, document every joint, every seam, every area of spalled sealant or corrosion. You see the photos. We explain what we’re looking at in plain English.
- 2
Clean and repair. For cerfractory systems, we mechanically remove loose sealant, sweep creosote and debris, and prep the masonry surface per HeatShield specifications. For stainless liners, we replace damaged sections with matching components. Crown cracks get sealed or rebuilt. Flashing gets addressed.
- 3
Recoat or reinstall. We apply HeatShield cerfractory sealant to manufacturer thickness, or install and secure HeatShield/UltraShield liner sections with proper fasteners and insulation. Every joint is visible on camera before we close up.
- 4
Test and verify. We run the camera again, verify draft performance, and provide a written sweep report with photos. Our 90-Day Done Right Promise covers the work - in writing, no arguing.
HeatShield Products We Service & Install in Easton
We work with all major HeatShield product lines: Cerfractory Flue Sealant for resurfacing sound masonry flues; HeatShield/UltraShield stainless-steel flue liner kits for gas, oil, and wood-burning appliances; cast-in-place refractory lining systems for heavily damaged flues that need structural rebuilding; and insulated chimney liner insulation blankets for improved draft and safety. We carry cerfractory sealant, primer, and crown repair materials on our Easton trucks, and we stock common HeatShield stainless liner diameters and insulation for faster turnaround on replacement jobs.
We Also Service These Brands
HeatShield is one of several professional-grade lining systems we work with. We also service and install DuraFlex stainless liners and Gelco chimney caps and accessories. Our technicians carry the full range because Easton chimneys are not all the same age, condition, or fuel type. The right product for the job depends on what we find in your flue.
FAQs - HeatShield Chimney Cleaning Service in Easton
No. We are an independent chimney service provider, not affiliated with or authorized by HeatShield. This means we diagnose your entire flue system - masonry, crown, flashing, and liner - rather than focusing only on the HeatShield product. Our independence lets us recommend the repair that actually solves the problem, not just the one that matches a brand protocol. Call (610) 756-1504 for a free estimate.
Yes, when the cerfractory sealant is properly bonded and in good condition. We use mechanical brushes and controlled scraping tools designed for lined flues, not the aggressive chain methods that can gouge sealant. If the coating is already failing, we’ll show you on camera before we start and recommend repair or recoat. A properly maintained HeatShield flue in Easton should be swept annually before burning season.
The signs are usually visible once you know what to look for. Grit or flakes in the firebox or on the smoke shelf after burning. A persistent smoky smell when the fireplace is not in use. Draft that used to be strong and now struggles. Water stains on the chimney breast. The only way to confirm is a Level-2 camera inspection - we run a camera the full flue length and show you exactly what we find. Call (610) 756-1504 to schedule.
A cracked crown does not automatically void a HeatShield warranty, but it will destroy the liner if left unrepaired. Water entering through the crown is the leading cause of cerfractory sealant failure we see in Easton. We repair crowns as part of our HeatShield service because the liner cannot survive without it. We document the crown condition in our inspection report and include repair in our recommendation when needed.
Yes. The HeatShield/UltraShield stainless liner kits come in diameters and lengths that match most wood-burning inserts, and we size the liner to the appliance’s exhaust output per NFPA guidelines. Easton’s oversized coal-era chimneys often need a properly sized liner to create adequate draft for a modern insert. We measure, we match, and we test before we leave.
Annually, before the first fire of the season. Easton’s heavy burning season and the creosote potential of local hardwoods mean that even a well-lined flue needs regular cleaning to maintain draft performance and safety. For homeowners who burn daily through the winter, a mid-season inspection is worth considering. Call (610) 756-1504 to book our Chimney Cleaning & Sweep services - estimates are free.
