Why Westwood Residents Choose Us for DuraFlex Service
Westwood’s pre-war brick housing stock isn’t forgiving to generic chimney work. Gary Murphy grew up in Yonkers’ Nodine Hill neighborhood, trained through Westchester Community College’s Building Trades program, and has spent 11 years specializing exclusively in chimney systems—no roofing, no gutters, no handoffs. He leads every job himself.
That matters in Westwood. The borough’s 1920s–1950s Colonials and Cape Cods near the Pascack Valley rail corridor have chimneys sized for coal, then oil, now gas—each conversion leaving a bigger problem in the flue. We’ve installed and maintained thousands of DuraFlex stainless steel liners in these exact conditions. Our 1,142 verified reviews at 4.7 stars reflect homeowners who got the decision-maker on their roof, not a dispatched crew working under a brand name.
We use genuine DuraFlex components—AL 31-6, ProConnect, Double-Wall—because off-brand liners fail in Westwood’s irregular flues. “I’ll tell you what I see, not what sells.” That’s the standard Gary learned from his finish-carpenter father: look a homeowner in the eye and explain exactly what you found.
Common DuraFlex Chimney Cleaning Problems We Solve in Westwood
- Acidic condensation eating 316L liners in 5–7 years. Westwood’s near-universal gas conversions dump condensing exhaust into oversized coal-era flues. Standard 316L stainless can’t handle the chemistry. We upgrade to AL 31-6 or 316Ti alloys that survive Bergen County’s wet winters.
- Oval liner buckling at the crown. Westwood’s 1920s brick chimneys settle unevenly after a century of freeze-thaw. DuraFlex AL 31-6 Oval liners crush at the shoulder where mortar has deteriorated. Our inspections catch this before the draft fails completely.
- Insulation breakdown in annular gaps over 2 inches. Common in 8×12 flues converted from oil to gas. The gap traps moisture, rots the liner from the outside in. We pack with DuraFlex-certified insulation wraps sized to Westwood’s actual flue dimensions.
- Multi-flue cross-contamination. On Broadway-adjacent blocks, deteriorated terra-cotta partitions between furnace and fireplace chases let soot migrate. Cleaning one flue without checking the other violates Bergen County code—and we’ve found creosote damming gas appliance flues because of it.
- Soot dams at first bends in uninsulated liners. Westwood’s low-pitched roofs and persistent Pascack Brook valley humidity accelerate condensation. Uninsulated DuraFlex liners in 8×8 flues build hard-packed soot dams that choke draft and back-dump CO. We remove the obstruction and fix the insulation gap.
DuraFlex Service in Westwood: What Local Conditions Mean for Your Equipment
Westwood developed as a Pascack Valley railroad suburb, its core built between the 1920s and early 1950s. The result is a dense concentration of brick Colonials and Cape Cods whose masonry chimneys were sized for coal, adapted for oil, and now struggle with natural gas. This isn’t a footnote—it’s the defining reality of chimney work in the 07675 ZIP.
On a recent job on Third Avenue near the Pascack Brook, we swept a DuraFlex AL 31-6 liner serving a 1950s gas conversion in a Dutch Colonial. The homeowner reported poor draft, and our Level 2 camera inspection revealed a 2-inch-thick soot dam at the first bend, caused by the oversized 8×8 flue left uninsulated—a classic Westwood issue. We removed the dam, installed a DuraFlex insulation wrap around the liner, and sealed the abandoned fireplace flue cap above, restoring draft and preventing future condensation buildup.
In Westwood’s Broadway-adjacent blocks, many chimneys were built with a single brick stack that houses both a fireplace flue and a furnace flue separated by a single course of deteriorated terra-cotta tiles—a configuration nearly unique to this railroad suburb, where our camera inspections regularly find creosote and soot cross-contaminating the furnace side, requiring two separate DuraFlex liners with an insulated partition. Most contractors don’t own the equipment to diagnose this. We do, because Westwood’s housing stock demands it.
DuraFlex Models & Products We Service in Westwood
We work with the full DuraFlex professional line, stocked for same-day Westwood turnaround:
- DuraFlex AL 31-6 — Our standard for gas appliance relining in Westwood’s oversized flues. The aluminum-enhanced alloy resists acidic condensation better than basic 316L, critical given the borough’s humid valley climate and repeated freeze-thaw cycles.
- DuraFlex AL 31-6 Oval — For tight chimneys where round liners won’t fit. Common in Westwood’s narrower 1920s flues near downtown Broadway, where brick dimensions weren’t standardized.
- DuraFlex ProConnect — Single-connector system for faster, more secure installation. We use this when Westwood homeowners need minimal disruption to occupied homes.
- DuraFlex Double-Wall — Required for wood-burning applications. Some Westwood homeowners still burn cordwood in original fireplaces; this meets NFPA 211 for solid fuel.
No off-brand substitutes. Westwood’s irregular flues—settled, spalled, often modified twice over—need the tight tolerances genuine DuraFlex provides. We carry OEM connectors, caps, and insulation wraps on our truck.
DuraFlex Service Pricing in Westwood
Costs reflect Westwood’s specific challenges: oversized flues need more liner material, shared-stack configurations take longer to inspect properly, and Bergen County’s wet climate means we don’t cut corners on alloy selection.

| Standard DuraFlex sweep + Level 2 inspection | $280 – $520 |
| Multi-flue cap installation | $340 – $680 |

FAQs — DuraFlex Chimney Cleaning in Westwood
Yes. We do this regularly on Broadway-adjacent blocks where shared-stack configurations are common. The key is installing an insulated partition between the two DuraFlex liners and verifying with a Level 2 camera inspection that no cross-contamination exists. Each flue gets its own properly sized AL 31-6 liner—typically 4-inch for the gas furnace, 6-inch for the fireplace—with independent terminations. Call (844) 660-6590 for a free inspection; we’ll show you exactly what your stack configuration requires.
Possibly, but the culprit is more often a failed terra-cotta partition in a shared-stack chimney than a breach in the DuraFlex liner itself. In Westwood’s pre-war housing stock, deteriorated clay tiles between flues let furnace exhaust migrate into the fireplace chase. Our camera inspection identifies whether the problem is partition failure, liner damage, or both. Call (844) 660-6590—soot odor indicates combustion byproducts where they shouldn’t be, and we treat it as urgent.
AL 31-6 or 316Ti. Standard 316L fails prematurely in Westwood’s conditions: condensing gas exhaust in oversized flues, plus Bergen County’s persistent humidity and freeze-thaw cycling. AL 31-6’s aluminum content resists the acidic condensation that destroys lesser alloys within 5–7 years. We’ve replaced too many prematurely failed 316L liners in Westwood Dutch Colonials to recommend anything less.
Yes. Our Level 2 inspection—standard with every DuraFlex sweep—includes video scanning the full liner length. We look for pinholes, corrosion patterns, joint separation, and insulation gaps. In Westwood’s gas-conversion chimneys, pinholes cluster at the first bend and crown shoulder where condensation pools. We document everything and explain what we found before recommending repair or replacement.
Almost always a new liner. Oil exhaust is dry and hot; gas exhaust is cool and condensing. An existing liner sized for oil is typically oversized for gas, creating the exact condensation problems we see constantly in Westwood’s 1950s conversions. The alloy may also be wrong—316L instead of AL 31-6. We assess your specific flue during our free estimate, but plan on replacement for safety. Call (844) 660-6590 to schedule; oil-to-gas conversions are time-sensitive and we prioritize them.
