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 Chimney Cleaning in Hempstead, NY | Flint Chimney Co Hempstead
We clean and service DuraFlex chimney liners in Hempstead, and here’s the short answer: a standard Hempstead Chimney Sweep for a DuraFlex liner runs $189 – $325 depending on flue condition and liner type. The one thing that makes our DuraFlex work different in Hempstead is that we account for the village’s legacy flue sizing, which is wider and shorter than modern code allows, and that changes how creosote builds on liner walls. Our independent status means we’re not tied to any manufacturer’s sales targets, so if your liner is sound, we’ll tell you that plainly. Call (516) 559-6922 for a written estimate before any work begins.
Why Hempstead Residents Choose Us for DuraFlex Service
Our technicians work on DuraFlex sales & service liners in Hempstead every week, from mid-century capes near the village center to pre-war colonials on the tree-lined streets off Fulton. We know the failure points of their single-wall and double-wall flexible aluminum and stainless systems as installed in oil-fired and wood-burning flues. We’re an independent service company, not affiliated with DuraFlex, which means our recommendations are driven by what’s safest and most durable for each Hempstead home, not by what a manufacturer wants us to push.
Hank Delano leads our crew here. He learned the trade at Los Angeles Trade-Technical College and has spent the better part of two decades running chimney cleaning crews across Nassau County, including steady work in the Fulton neighborhood right here in Hempstead. His approach hasn’t changed: clean inspections, straight answers on liner condition, and no quoting work a chimney doesn’t actually need.

Common DuraFlex Chimney Cleaning Problems We Solve in Hempstead
- Torn or perforated inner walls in DuraFlex SW liners. We see this often in older Hempstead flues with irregular clay tile. Years of creosote removal with metal brushes can wear through the thin aluminum single-wall liner, especially around bends where the liner presses against jagged clay edges. A camera inspection shows the damage before we recommend anything.
- Corrosion pinholes in aluminum liners from damp Hempstead winters. Hempstead’s humid continental climate means condensation inside chimneys is a near-constant from November through March. Where a DuraFlex liner passes through an uninsulated attic, warm flue gas meets cold ambient air, and the resulting moisture eats tiny holes into aluminum over time. We find these routinely during Level 2 inspections on older homes.
- Separation at the liner-to-connector joint in DuraFlex DW systems. Oil burner combustion cycles produce steady thermal expansion and contraction. On double-wall DuraFlex installations in Hempstead, that repeated cycling can loosen the connection where the liner meets the appliance connector, creating a gap that leaks flue gas. We check this joint on every oil-fired system we service.
- Hardened creosote glaze along corrugated liner walls. Hempstead’s older colonials and cape cods in the village center frequently have short, wide flues. That geometry slows draft, and slower draft means more creosote deposition. On DuraFlex aluminum liners, the corrugated walls give glaze a perfect surface to grip. Restricted draft and smokeback are the result.
- Improperly fitted liners from previous installs. We’re regularly called to homes in Hempstead where a previous contractor installed a DuraFlex liner without proper termination at the top plate. Liner sag, unsealed connectors, and missing insulation wraps show up on our camera inspections. We correct these so the liner actually does its job.
DuraFlex Service in Hempstead: What Local Conditions Mean for Your Equipment
Here’s the detail that matters in Hempstead and nowhere else quite the same way: in the village’s historic district, many chimneys still vent oil-fired boilers through flues sized for coal. When those boilers were replaced with modern high-efficiency units, the flue gases became cooler. Add a short, wide flue in a pre-WWII colonial, and that cooler gas condenses on liner walls before it ever clears the chimney. The condensation mixes with creosote and creates a hard glaze that’s difficult to remove and can corrode aluminum liners faster than anything we see on newer construction.
For DuraFlex owners in Hempstead’s older housing stock, this means annual Hempstead Chimney Inspection visits are not a suggestion. On Fulton Avenue, on Front Street, down by the village center, we recommend a more frequent inspection cadence than the standard annual checkup if your oil-fired system still runs through a legacy flue. The flue tells the truth. You just have to know how to read it.
DuraFlex Models & Products We Service in Hempstead
We service every DuraFlex liner regularly installed in Hempstead homes. That includes DuraFlex SW, the single-wall flexible aluminum liner common on older oil-fired systems; DuraFlex DW, the double-wall aluminum liner used where a little more insulation matters; DuraFlex 316Ti, a flexible stainless liner we prefer for wood-burning applications and high-heat exposure; and DuraFlex Pro, their heavier stainless option for long runs or difficult flues.
On parts, we use genuine DuraFlex components such as connectors, caps, and top plates whenever sourcing is quick. When genuine parts aren’t available quickly or a different alloy spec serves the home better, we install equivalent aftermarket parts made to the same dimensions and material specifications. We’ll tell you which is which on the written estimate, before any work starts.

FAQs – DuraFlex Chimney Cleaning in Hempstead
No, and that’s deliberate. We’re an independent DuraFlex service provider in Hempstead. We’re not manufacturer-affiliated, which means we don’t have quotas on liner replacements or pressure to push one product over another. We source genuine DuraFlex parts when they’re the right call and quality aftermarket equivalents when they serve you better.
No, but a yearly Level 1 inspection is still worth doing here. Hempstead’s damp winters bring condensation into chimneys even when the fireplace sits cold, and a short, wide legacy flue can hide creosote you won’t see from the hearth. If you burn even a cord of wood per season, an annual sweep is the safer cadence. Call (516) 559-6922 and we’ll give you a straight answer on your specific setup.
Whenever we can source them quickly, yes. Genuine DuraFlex connectors, caps, and top plates go in where the original liner is in good enough shape to keep. When a DuraFlex liner has more than a few pinholes or a torn section, a patch is a false economy, and we’ll tell you that directly. We recommend replacing that segment or the full liner rather than chasing a repair that won’t hold.
Most DuraFlex sweeps in Hempstead take 60 to 90 minutes for a standard single-family home. If your liner needs a camera inspection, which we recommend on any liner older than five years, add 20 to 30 minutes. We protect the floor and leave the hearth cleaner than we found it.
A standard sweep runs $189 – $325. If the liner is in rough shape, repairs run $350 – $900, and a full liner replacement runs $1,800 – $4,500. Those numbers are written down before any work starts. Call (516) 559-6922 for a free estimate, no inspection fees and no phone-tree runaround.
