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.
DuraFlex Fireplace Services in Paterson: What to Know First
We provide independent DuraFlex fireplace services across Paterson, from gas fireplace tune-ups to wood-burning firebox repairs and insert conversions. Most DuraFlex jobs we book are completed in a single visit, with upfront pricing agreed before we start. You’re not buying a mystery, you’re buying the repair done right.
This page is for Paterson homeowners who already have a DuraFlex liner, insert, or chimney component in their fireplace system and need service from someone who knows the product line without upselling you into a full replacement you may not need. If you live in the Eastside, the Hillcrest area, or near the older brick homes around Garrett Mountain, we’ve likely worked on a stack just like yours.

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (Stainless Wall) liners crack at the flex points after thermal cycling. In Paterson’s freeze-thaw climate, the expansion and contraction between the inner stainless wall and the outer corrugated layer creates fatigue at the elbows. We’ve replaced sections in the 316Ti alloy where the creosote corrosion accelerated the split. We cut in a new DuraFlex SW section with factory-compatible couplings, not generic clamp-togethers that void your existing warranty.
- DuraFlex Pro inserts develop draft issues when the refractory panels shift. The Pro series uses lighter refractory cement than some competitors, which saves weight on installation but can settle after five to seven heating seasons. We see this in Paterson’s 1920s and 1950s homes where the original firebox dimensions weren’t perfectly square to begin with. We reset the panels with high-temp refractory mortar and check the flue collar seal, which is where the real draft loss usually hides.
- DuraFlex AL (Aluminum) gas vent connectors corrode at the drip leg. The AL series is rated for gas appliances only, but we still find them in Paterson basements where a previous owner ran a gas log set off an old oil-burner chimney. The aluminum reacts with condensate at the low point. We replace with DuraFlex AL where the appliance rating allows, or upgrade to a proper stainless gas vent if the BTU load demands it. We document the appliance plate before we spec anything.
- DuraFlex Tee connectors separate at the snout joint on exterior chimney runs. Paterson’s wet winters and the salt air off the Passaic Valley accelerate exterior corrosion at the tee body where the snout meets the main barrel. The tee is the most expensive fitting in the system, so we inspect with a camera before condemning it. Often we can reseal with a DuraFlex-compatible high-temp silicone and add a proper storm collar where the previous installer skipped it.
- DuraFlex relining systems lose insulation integrity when the mesh wrap degrades. The DuraFlex relining system depends on a ceramic blanket held by stainless mesh. After fifteen to twenty years, the mesh can sag, creating cold spots that condense flue gases into creosote. In Paterson’s older homes with exterior chimneys on the north face, this happens faster. We assess with a level-2 camera inspection and can re-insulate with fresh DuraFlex-compatible blanket or recommend a HeatShield Cerfractory seal if the liner body itself is still sound.
Our DuraFlex Fireplace Services Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask for your appliance model, the symptoms, and whether you’ve had previous liner work. No app, no callback queue.
- 2
Level-2 camera inspection on arrival. Our technician runs a camera the full length of the flue and photographs every joint, tee, and transition. You see the images on the screen while we explain what we’re looking at.
- 3
Parts diagnosis: OEM DuraFlex or quality aftermarket. We check what’s in stock from our DuraFlex, HeatShield, and Gelco suppliers. If your warranty is still active, we use OEM couplings and factory-spec gaskets. If the warranty has aged out, we may recommend a Gelco or Olympia Chimney equivalent that meets the same UL 1777 standard at lower cost. You decide before we order.
- 4
The repair, done in one visit when possible. Our trucks carry common DuraFlex fittings, refractory mortars, and gas vent connectors. Most Paterson jobs finish the same day. If we need to order a specialty tee or custom-length liner section, we schedule the return before we leave and lock in the price.
- 5
Combustion test and draft check. For gas fireplaces, we verify CO levels and manifold pressure against the appliance rating plate. For wood-burning systems, we check draft with a digital manometer and do a smoke-pencil test at the firebox opening.
- 6
Written documentation and the 90-Day Done Right Promise. You get photos, a plain-English verdict, and our guarantee in writing. If it’s not right, we make it right. No paperwork to find, no arguing.

Why Paterson Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been answering the phone in Passaic County for over 42 years. Russell Haines learned this trade at Los Angeles Trade-Technical College and has spent the better part of two decades on Paterson chimneys from Eastside to Garrett Mountain. His crew knows the difference between a DuraFlex SW elbow that can be patched and one that needs replacement because they’ve pulled enough of each to tell by the crack pattern.
We document everything with photos you can see and a plain-English verdict you can understand. Our 90-Day Done Right Promise is in writing with no arguing. If we install a DuraFlex tee and it leaks, we come back. Most jobs complete in one visit because our trucks carry the parts. And when DuraFlex stock is backordered, we have HeatShield and Gelco equivalents that meet the same standards, so you’re not held hostage by a supply chain.
Find the problem, say what it is, fix it right. That’s how we work.
FAQs
No. As an independent DuraFlex service provider, we use OEM-spec parts and follow UL 1777 installation standards, which preserves manufacturer warranty coverage. We are not affiliated with or authorized by DuraFlex, but we know their product line well enough to keep your warranty intact. If your warranty claim requires documentation, we provide detailed photos and written reports from our inspection. Call (973) 604-2986 if you need warranty paperwork for a recent install.
Most common DuraFlex SW and AL fittings ship to us within three to five business days. Specialty tees and custom liner lengths can take seven to ten days. We keep HeatShield and Gelco equivalents in stock for urgent situations where the flue is unsafe to use, and we’ll explain the trade-offs before we substitute. We schedule your return visit before we leave the first call so you’re not waiting on a callback.
Replace if the liner has multiple cracked sections, the insulation blanket is saturated with creosote, or the appliance has been changed to a higher-BTU unit the original liner wasn’t sized for. Repair if the damage is localized to one elbow or tee, the insulation is still dry and properly positioned, and the sizing matches your current appliance. We make this call with camera evidence you can see, not a sales pitch. Sometimes the honest answer is that it can wait a season. When that’s true, we say so.
Annually for wood-burning systems, every two years for gas fireplaces that see regular use. Paterson’s wet winters and the freeze-thaw cycles off the Passaic Valley accelerate exterior corrosion and interior condensation. Older homes with unlined original chimneys that were retrofitted with DuraFlex in the 1990s or 2000s should be checked yearly regardless of fuel type. The $89 seasonal tune-up catches problems before they become $800 repairs. Call (973) 604-2986 to book.
Delayed service on a DuraFlex AL gas vent risks carbon monoxide leakage through corroded joints, and delayed service on a DuraFlex Pro wood insert risks creosote buildup that can ignite in the liner. Gas systems can also develop manifold pressure drift that wastes fuel and produces excess moisture, accelerating corrosion. Neither failure happens overnight, which is why the annual check matters. We find the problems early, say what they are, and fix them before they become dangerous. Call (973) 604-2986 for a free estimate.
