DuraFlex Chimney Cleaning in Flushing, NY | Flint Chimney Co Hempstead
We provide independent DuraFlex chimney cleaning and liner service throughout Flushing. We are not a manufacturer affiliate. What sets our DuraFlex work apart here is the housing: attached rowhouses, shared flues, multi-boiler conversions. Before we sweep a DuraFlex liner in Flushing, we start with our Chimney Sweep in Flushing by checking the drafting across every connected flue. Call (516) 559-6922 for a written estimate before any work begins.
Why Flushing Residents Choose Us for DuraFlex Service
Flushing has a lot of chimneys squeezed into a small footprint. Prewar rowhouses on streets like 45th Avenue and frame homes converted to multi-unit rentals all share walls and sometimes share flues. That changes how a DuraFlex liner gets cleaned. Hank Delano, who runs Flint Chimney Co Hempstead, has spent the better part of two decades running chimney crews across Nassau County, including steady work in the Fulton neighborhood in Hempstead. He learned the trade at Los Angeles Trade-Technical College and brings that trade-school discipline to every Flushing job. We know DuraFlex 316L and 304 liners, ProConnect fittings, and Xtreme components from field use, not from a sales brochure.
We carry OEM DuraFlex connectors, clamps, and couplers for common sizes. When a Flushing homeowner has an older or discontinued liner size, we source certified 316L stainless aftermarket equivalents that meet the same UL listing. We evaluate the liner’s remaining lifespan before recommending repair or replacement, especially in party-wall chimneys where your neighbor’s flue shares the load. Our techs arrive background-checked and uniformed. The price is in writing before a tool comes off the truck. Every repair carries a written one-year guarantee. If a covered repair fails within that year, we return at no charge.

Common DuraFlex Chimney Cleaning Problems We Solve in Flushing
- Salt-air corrosion and pitting on DuraFlex 316L liners. Flushing Bay sits close enough that damp, salt-laden air works into chimney systems and accelerates corrosion on stainless steel that would stay clean further inland. We inspect for pitting at the liner’s upper sections and around the termination cap during every cleaning.
- Creosote packed into the corrugated walls of multi-flue rowhouse chimneys. Flushing’s attached brick rowhouses often run multiple DuraFlex liners in one masonry chase, each serving a separate boiler. Long heating cycles in converted multi-unit rentals build creosote faster in the liner’s ridges. Our rotary brush work is sized to the liner diameter, not the masonry opening.
- Slipped or disconnected liner sections at offsets in prewar conversions. Flushing has thousands of pre-1930 rowhouses where a clay tile flue was later relined with DuraFlex. Offsets above boiler connections are a common failure point. A slipped section lets flue gases leak into wall cavities, which becomes a carbon monoxide risk when the wall is shared.
- Cracked mortar joints around the liner termination. Flushing’s freeze-thaw cycles open up mortar at the crown faster than homeowners expect. Water gets behind the liner and freezes, widening the gap. We repair the crown and confirm the liner is still seated before we sweep.
- Drafting imbalance in shared chimneys. When one attached neighbor relines only their side, the unlined side can pull flue gases back toward the adjacent home. We see this consistently in Murray Hill and Broadway-Flushing. Our cleaning always begins with a drafting check at each connected flue outlet.
DuraFlex Service in Flushing: What Local Conditions Mean for Your Equipment
The block-level reality of Flushing’s Murray Hill and Broadway-Flushing rowhouse belts is this: many pre-1930 chimneys are shared between attached units, and many now carry separate DuraFlex liners installed at different times, by different contractors, under different permits. When one neighbor relines only their side, the resulting pressure imbalance can pull carbon monoxide into the adjacent home. It is not theoretical. We have measured backdraft at party-wall outlets in Flushing homes where the liner itself was fine. That is why our cleaning always starts with a shared-flue drafting assessment before any sweeping. If the system does not draft correctly, the cleanest liner in Queens will not keep a family safe.
On a 1920s brick rowhouse on 45th Avenue in Murray Hill, our tech found a DuraFlex 316L liner that had slipped at the offset above the boiler connection. Flue gases were leaking into a wall cavity shared with the attached neighbor. We re-secured the liner with a stainless coupler, swept three seasons of creosote from the corrugated interior, and confirmed zero backdraft at every party-wall outlet before sealing the access. The flue tells the truth. You just have to know how to read it.
DuraFlex Models & Products We Service in Flushing
We service four DuraFlex product families in Flushing: the DuraFlex 316L stainless steel flexible liner, the DuraFlex 304 stainless steel flexible liner, the DuraFlex ProConnect liner, and the DuraFlex Xtreme liner. The 316L is the common choice for Flushing because of its molybdenum content, which resists the salt-air corrosion we see near the bay. ProConnect and Xtreme lines show up most often in post-war apartment conversions where the original clay tile failed.
We stock common OEM DuraFlex couplers, clamps, and termination caps for faster Flushing turnaround. When an older liner size is no longer manufactured, we fit certified 316L stainless aftermarket parts that preserve the UL listing. Every repair or replacement decision is based on what the liner actually needs, not what is easiest to bill. See our broader DuraFlex sales & service page for the full product discussion.

AfterDuraFlex Service Pricing in Flushing
A standard DuraFlex chimney cleaning with a Flushing Chimney Inspection Level 1 in Flushing typically runs between $225 and $350, depending on liner diameter, roof access, and whether the flue is shared. A Level 2 inspection with camera runs higher, usually $400 to $600, because it involves rooftop access, interior wall evaluation at the party wall, and full video documentation of the liner interior. Creosote removal on a heavily fouled multi-flue rowhouse chimney can push a cleaning into the $350 to $475 range. Damper repair on a DuraFlex-equipped Flushing chimney typically adds $180 to $325 depending on the damper type and access.
Those are honest ranges, not teasers. The written estimate we give you before work starts includes the exact price, the scope, and the guarantee terms. If a covered repair fails within one year, we return free. Call (516) 559-6922 and we will put it in writing.

FAQs – DuraFlex Chimney Cleaning in Flushing
Stainless steel resists corrosion, but it is not immune to it. Flushing’s damp, salt-laden air from Flushing Bay works into the chimney system and settles on the liner’s inner and outer walls. Over years, that moisture film eats at the liner’s surface, especially where condensation collects after long boiler cycles. We see it most on 304 liners and on the upper sections of 316L liners where the termination cap has failed. We inspect for pitting at every cleaning and tell you plainly if the liner has years left or needs replacement.
We isolate the flue we are working on and run our brushes only inside that liner’s diameter. Before we touch anything, we map which liner serves which unit and verify the drafting at each party-wall outlet. That drafting check is the part most chimney companies skip. In Flushing’s attached rowhouses, skipping it is how you pull smoke or carbon monoxide into someone else’s kitchen. We do not skip it. Call (516) 559-6922 to schedule a Flushing shared-flue assessment.
In most cases, yes. We use a camera system that runs through the liner from the roof or from the boiler connection. The camera shows us the liner’s interior condition, any disconnected sections, and any creosote buildup without opening a wall. There are exceptions. Some prewar Flushing conversions have offsets so tight the camera cannot pass, and some liner failures are only visible where the wall cavity is open. We tell you before the inspection starts what we expect to see, and we show you the footage when we are done.
Yes. A stainless liner still accumulates creosote, sometimes faster than a smooth clay tile because the corrugated walls catch more particulate. In Flushing’s attached rowhouses, where multiple boilers run long cycles and the liner cools unevenly, we recommend an annual cleaning and inspection. Clay tile chimneys can sometimes stretch to 18 months. A DuraFlex liner in a multi-unit Flushing conversion should not. The inspection is where we catch corrosion and slipped sections before they become a carbon monoxide problem. Call (516) 559-6922 for a Flushing-specific cleaning schedule and a written quote.
We repair the crown first when the damage is letting water into the flue. Sweeping a liner while water is actively entering through a failed crown wastes the cleaning. The crown is what keeps rain and snow out of the liner’s upper section. Once the crown is repaired and cured, we sweep the liner and inspect it for the moisture damage that already occurred. If the crown failure has been going on for years, we may recommend a Level 2 camera inspection to check for corrosion or separation. We will show you the footage. Call (516) 559-6922 and we will put the repair sequence and price in writing before any work starts.
