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.

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex DW (double-wall) gas fireplace inserts: The pilot assembly on these units tends to soot up faster than single-wall designs, especially in New City’s older colonials where the firebox depth is shallow and combustion air is limited. We clean the pilot orifice with OEM-spec tools, check the thermopile output in millivolts, and replace the assembly only when it tests below 325 mV - not before.
- DuraFlex AL (aluminum) flexible liners in wood-burning fireplaces: The aluminum reacts with creosote acids over time, particularly when homeowners burn unseasoned hardwood from local suppliers near the Palisades. We see pinholing near the first bend above the smoke chamber. We document it with camera inspection, then replace with DuraFlex stainless or transition to HeatShield cerfractory foam if the flue is structurally sound.
- DuraFlex SS (stainless) chimney liner connections: The collar-to-adapter seal loosens after 8-12 years of thermal cycling in New City’s freeze-thaw climate. Carbon monoxide can leak into the chase before you smell anything. We pull the fireplace surround, reseat the connection with high-temp sealant rated to 2000°F, and pressure-test the joint.
- DuraFlex direct-vent gas fireplace glass fogging: Not a cleaning issue - it’s a failed gasket on the sealed combustion door, common on units installed during the 2005-2012 building boom near New City’s Veterans Memorial Park area. We source the correct DuraFlex gasket by serial number, never generic strip-cut, so the unit maintains its listed efficiency rating.
- DuraFlex damper hardware in wood-to-gas conversions: The original cast-iron throat damper was never meant for the lower exhaust temperatures of a gas insert. It rusts in place. We remove it without dropping debris into the firebox, then install a Gelco top-sealing damper or lock the unit open per code, depending on your venting configuration.
Our DuraFlex Fireplace Services Process
- 1
Call and schedule: A live person answers at (845) 599-0930, 24/7. We book a window that works for you - no app, no callback queue.
- 2
Level-2 camera inspection: Our technician arrives in uniform, runs a camera through the flue or examines the gas components, and takes photos you can see on the spot. You get a plain-English verdict on what’s actually wrong.
- 3
Parts decision: We check DuraFlex OEM availability against quality aftermarket options. Some parts - like the DW pilot assembly - we source OEM. Others, like gaskets, we may use an equivalent from Famco or Copperfield if it meets the same spec and saves you money without voiding your warranty rights.
- 4
The repair: Most DuraFlex fireplace services are completed in one visit. Our technicians are background-checked and trained on DuraFlex-specific clearances and combustion requirements.
- 5
Testing and documentation: We run the unit through a full cycle, check CO levels at the fireplace face, and give you the photos and written report for your records.
- 6
The guarantee: Every job is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we don’t leave until it is.
What DuraFlex Fireplace Services Costs in New City
Pricing depends on access, parts, and whether we need a second technician for liner work. Here’s what DuraFlex fireplace services typically run in the New City market:
- DuraFlex gas fireplace tune-up and safety check: $89 (our seasonal special)
- Pilot assembly cleaning or replacement: $180-$340
- Glass gasket replacement: $220-$390
- Damper repair or conversion lock-open: $280-$520
- Flexible liner inspection with camera: $240-$350
- Liner section replacement (DuraFlex SS or AL): $1,200-$2,800 depending on height and access
Factors that move the price: chase height, whether the fireplace is on an exterior wall with limited roof access, and whether the original installer left adequate connection slack. We always give you the full price before starting - no surprises on the bill. Call (845) 599-0930 for a free estimate.
Why New City Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been serving New City and Rockland County for over 42 years. Russell Haines and our crew know the local housing stock - the 1970s splits near the Tappan Zee corridor, the pre-war brick colonials closer to downtown - and we know how DuraFlex products were installed in each era.
Our Level-2 inspections end with photos you can see and a plain-English verdict. If your DuraFlex unit needs backup from HeatShield for flue resurfacing or Gelco for cap and damper work, we carry those lines too - no calling in a second contractor. The 90-Day Done Right Promise covers every job in writing. Done right - and we stand behind it.
FAQs
No. The Magnuson-Moss Warranty Act prohibits manufacturers from voiding your warranty simply because you chose an independent service provider. We use parts that meet or exceed DuraFlex specifications, and we document everything so you have records if a warranty question ever arises. Call (845) 599-0930 if you’d like us to review your warranty status before we start.
Most common DuraFlex parts - pilot assemblies, gaskets, flex sections - are available within 2-3 business days through our distributors. For older or discontinued series, we sometimes source quality aftermarket equivalents from Copperfield or Famco that meet the same pressure and temperature ratings. We’ll tell you before ordering if there’s any delay.
Repair is usually the better value if the firebox and flue are sound. We replace DuraFlex units when the heat exchanger is cracked, the liner is compromised beyond section repair, or repair costs exceed 60% of a new installed unit. Our camera inspection shows you exactly what you’re dealing with - no guesswork, no pressure. Call (845) 599-0930 for a free estimate.
Once a year, before the heating season. Even clean-burning gas units accumulate dust on the burner, degrade gaskets, and develop pilot issues that won’t show until the first cold night in New City. Our $89 Seasonal Tune-Up includes a full safety check and cleaning.
Carbon monoxide risk increases as combustion components degrade, and small problems become expensive ones. A stuck damper or cracked fireback that we catch early costs a few hundred dollars to fix. Left alone, it can damage the surrounding structure. The inspection itself is the cheap part. Call (845) 599-0930 to schedule - estimates are free.
