Paterson’s housing stock was built overwhelmingly during the 1880s-1920s silk industry boom as dense worker row homes, and the original coal-burning masonry chimneys in these buildings have since been converted through oil to gas appliances. Those oversized, often unlined or deteriorated flues-never designed for modern low-temperature gas exhaust-produce chronic draft failures, accelerated liner breakdown, and moisture infiltration that is endemic on virtually every residential block in the city. DuraFlex flexible stainless relining systems are one of the most common solutions we encounter in these stacks, and we’ve learned their failure patterns the hard way: by climbing them, brushing them, and pulling them when they’ve reached end of life.

We’re an independent chimney contractor, not affiliated with, authorized by, or sponsored by DuraFlex. That independence matters. We diagnose the entire venting system, not just the parts we sell. If your crown is cracked, your smoke chamber is corbeled, or your flue is sized wrong for the appliance below it, we’ll tell you before we touch the liner. Russell Haines, our owner, learned the trade at Los Angeles Trade-Technical College and has spent the better part of two decades working chimneys across Passaic County. His crew has handled Duraflex service in Passaic County and cleaned and repaired stacks in Paterson neighborhoods from Eastside to the blocks around Garrett Mountain, where older brick homes keep a sweep busy from September through March.

Why Trust Hearthstone Chimney Co. for Your DuraFlex Chimney Cleaning?

We know the DuraFlex product families because we’ve installed them, cleaned them, and pulled failed ones out of Paterson chimneys for years. The 316L flexible stainless kits, the 304 alloy relines for higher-temp solid-fuel appliances, the Pro and SS double-wall insulated systems, the direct-vent and pellet-vent components in 4″ and 3″ diameters-we’ve worked with all of them in the field. Our technicians carry DuraFlex top plates, appliance adapters, and gasket kits on the truck, so when a gasket dries out or an adapter loosens, we fix it that visit.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. We document the liner condition, the mortar joints, the crown, the smoke chamber, and the appliance connection. If the DuraFlex liner is sound, we clean it and re-gasket it rather than pushing a full reline. When the alloy has pitted through or the corrugation is packed with glaze we can’t safely brush out, we’ll show you the camera footage and tell you it’s time to replace that run. No surprises on the bill. The number on the estimate is the number on the invoice.

Russell built Hearthstone on one straightforward idea: find the problem, say what it is, fix it right. He keeps a small notebook in his truck where he sketches damper problems the way some people sketch floor plans, just to make sure nothing gets missed. His flue inspections are thorough enough that customers say they never worry about their fireplace after he has been through it. Background-checked, uniformed technicians. Most jobs completed in a single visit. And a live person answers the phone 24 hours a day, 7 days a week.

Common DuraFlex Chimney Cleaning Problems We Fix in Paterson

• Top-plate and cap gasket failure. The rubberized gaskets on older DuraFlex relines dry out and crack after years of UV exposure and freeze-thaw cycling. In Paterson’s climate, this is nearly predictable. Rain water tracks down the outside of the liner, past the failed gasket, and into the smoke chamber and firebox. We see this on Eastside row homes where the chimney crown is too flat to shed water quickly. The fix is a genuine DuraFlex top-plate replacement with fresh gaskets, not caulk or tar.
• Appliance adapter loosening. The compression band or appliance adapter on a DuraFlex 316L or 304 liner loosens after years of heat cycling. The liner pulls slightly off the appliance collar and spills smoke at the firebox. Homeowners smell it first, sometimes before they see it. Our crew was called to a two-family on the Eastside after a homeowner smelled smoke in the second-floor unit every time the insert ran; we found a DuraFlex 316L reline whose top-plate gasket had failed and whose appliance adapter had worked loose at the collar. We pulled the insert, removed roughly a gallon of glazed creosote from the liner corrugations, installed a new DuraFlex top plate and adapter gasket kit, and re-set the cap. Draft measured normally and the smoke smell stopped.
• Stage 3 creosote glazing on corrugated walls. The ridges in a DuraFlex flexible liner trap soot that a standard round brush skips. Wood-burning appliances in Paterson’s older homes often run cooler than designed because the chimney is oversized for the insert, and cool flue gases condense into glazed creosote. This is a fire hazard and it chokes draft. We use rotary cleaning systems designed for corrugated stainless to break glaze without damaging the alloy. That same Eastside visit we documented the crack in the crown so the owner could schedule crown coating before the next freeze-thaw cycle.
• Insulation wrap degradation on exterior-chase relines. The insulation wrap on DuraFlex Pro and SS double-wall systems gets torn or compressed during installation or a later cap repair. This degrades the liner’s UL 1777 listing performance and reduces draft, especially in Paterson’s taller three-story row homes where the Passaic River valley wind channeling already compounds downdraft problems. We inspect wrap condition with the camera and replace damaged sections with equivalent UL-listed insulation before re-listing the system.
• Corrosion in multi-flue party-wall chimneys. In Paterson’s attached row homes, a single chimney breast commonly serves multiple flues for two or three adjoining units across separate property lines. A blocked or cracked DuraFlex liner isn’t just one household’s problem. It creates carbon monoxide exposure and legal liability that crosses ownership boundaries, a scenario sweeps in single-family suburban towns almost never encounter. We document shared-flue conditions carefully and explain what we’re seeing to each affected owner.

DuraFlex Parts & Our Repair-vs-Replace Approach

We stock genuine DuraFlex top plates, appliance adapters, and gasket kits so the liner keeps its listed components. For wear items like cap screens, storm collars, and insulation wrap, we use equivalent UL-listed aftermarket parts when the OEM piece is backordered. This keeps your system safe and listed without waiting three weeks for a factory box.

Our rule is simple: if the DuraFlex liner is structurally sound, we clean and re-gasket it. If the alloy has pitted through from acidic condensation, if the corrugation is packed with glaze we can’t safely remove, or if the liner has pulled away from the appliance and can’t be reseated properly, we’ll tell you it’s time to replace that run. We’ll show you the camera footage. We’ll explain why. And we’ll give you an upfront price for either path. Call (973) 604-2986 and we’ll walk you through what we found.

Our DuraFlex Service Process - Step by Step

1. 1
   Diagnosis with Level-2 camera inspection. We run a camera the full length of your DuraFlex liner, looking for gasket condition, adapter seating, creosote buildup pattern, alloy pitting, and insulation wrap integrity. You see the photos. We explain what they mean in plain English.
2. 2
   Repair or install with OEM-compatible parts. We clean with tools matched to your liner’s corrugation pattern, replace failed gaskets and adapters with genuine DuraFlex components or equivalent UL-listed parts, and reseat the liner properly at the appliance collar.
3. 3
   Draft and spillage testing. We fire the appliance and verify draft pressure, check for smoke spillage at the firebox and joints, and confirm the cap is venting properly in Paterson’s localized wind conditions.
4. 4
   Documentation and warranty. You receive photos, a written verdict, and our 90-Day Done Right Promise. If it’s not right, we come back. In writing, no arguing.
