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 Chimney Repair in Staten Island: What to Know First
We provide independent DuraFlex chimney repair in Staten Island, with most jobs completed in a single visit and upfront pricing agreed before we start. Typical turnaround from call to repair is three to five business days, and we’ll tell you plainly if the fix can wait or if it needs attention now. Our 90-Day Done Right Promise covers every DuraFlex repair in writing - no arguing, no paperwork chase.
This page is for Staten Island homeowners who already have a DuraFlex liner, cap, or chimney component and need it repaired correctly the first time. If you’re in Tottenville, Great Kills, or anywhere across the island and your chimney needs honest attention, call us at (516) 613-3035. A live person answers, 24 hours a day.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW stainless liners in salt-air exposure. The SW series handles most venting well, but in Staten Island’s coastal zones - especially homes near the Arthur Kill or Raritan Bay - the 316Ti alloy can show pinpoint pitting at the flex joints after seven to ten years. We section-scan with our camera, mark the exact spans, and splice in matching-gauge DuraFlex replacement sections rather than selling you a full reline you don’t need.
- DuraFlex AL aluminum liners in oil-fired systems. The AL series is rated for gas and oil, but we’ve found the lower-temp aluminum can sag where it passes through older Staten Island masonry with irregular flue passages - particularly in 1920s bungalows around Westerleigh. We support the sag with DuraFlex-listed support components, or we upgrade to SW stainless if the appliance output warrants it. No guesswork: we measure flue gas temperature at the appliance collar before recommending.
- DuraFlex relining tees in high-sulfur oil setups. The tee body on earlier DuraFlex oil installations can develop creosote bridging at the dead-leg, especially when homeowners switch from #2 to blended fuel without adjusting the barometric damper. We pull the tee, inspect the interior weld seam (a known stress point), and either clean and reseat or replace with a current-spec tee that has the improved interior radius.
- DuraFlex termination caps with mesh degradation. The factory spark arrestor mesh on DuraFlex caps can clog with coastal debris - pine needles from the island’s mature oaks and maples, plus the fine grit that blows in off the water. We clean what we can, but when the mesh is corroded through, we fit a Gelco or Olympia Chimney cap with equivalent or better spark protection and proper overhang for Staten Island wind exposure.
- DuraFlex connector pipes in converted fireplace installations. The flexible connector from appliance to liner can work harden at the bend points in installations where the firebox throat is offset, common in pre-war Staten Island row houses. We replace with fresh DuraFlex connector stock, add a factory support at the bend, and document the installation with photos for your file - and ours.
Our DuraFlex Chimney Repair Process
- 1
Call and schedule. A live person answers, notes your DuraFlex product line if you know it, and books a Level-2 camera inspection. We confirm our $50 Off Any Repair Over $250 offer applies.
- 2
Camera inspection and verdict. Our technician runs a full video scan of the flue, the liner, and the exterior masonry. You see the footage on a tablet as we go. We give you a plain-English verdict: what’s wrong, what caused it, and what happens if you do nothing.
- 3
Parts decision - OEM or quality equivalent. For DuraFlex repairs, we source factory DuraFlex components when they’re the right choice. When lead times stretch or a quality aftermarket part from Olympia Chimney or Famco matches the spec at equal durability, we explain the trade-off and let you decide. No hidden substitutions.
- 4
The repair, documented. Our background-checked, uniformed technician completes the repair, pressure-tests or smoke-tests as appropriate, and photographs the finished work. Most DuraFlex repairs finish in one visit.
- 5
Written guarantee and follow-up. You get the 90-Day Done Right Promise in writing before we leave. The number on the estimate is the number on the invoice. We’ll call in thirty days to confirm everything’s performing.

Why Staten Island Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been servicing Staten Island chimneys for well over a decade, and we’ve learned which DuraFlex installations hold up and which ones need attention before they become bigger problems. Russell Haines and our crew have worked on older masonry fireboxes in Tottenville that have seen generations of hard winters - we know the local brick, the local weather, and the local fuel switching that stresses liners differently than inland markets.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. If the chimney’s sound, I’ll say so. If it isn’t, you’ll hear that too. The 90-Day Done Right Promise means if it’s not right, we come back - in writing, no arguing. And when DuraFlex parts are backordered, we have HeatShield and Gelco solutions that meet the same professional spec, so you’re not left waiting while burning season approaches.
FAQs
No - provided the repair uses DuraFlex-listed components and follows installation guidelines. As an independent DuraFlex service provider, we use factory or equivalent-spec parts and document the work. If your liner is still under original warranty, we note the repair in our report so warranty coverage remains intact. Call (516) 613-3035 and we’ll check your install date against warranty terms.
Most DuraFlex repairs we complete in two to four hours on site, with the job done in a single visit. Full relining takes a full day. We book three to five business days out in normal season; we don’t promise same-day because we’d rather do it right than do it fast. Call for current scheduling.
Repair is the right call when the damage is localized - a failed section, a damaged tee, or a degraded cap. We replace when the liner shows widespread corrosion, multiple seam failures, or when the original installation used undersized or mismaterial stock for the appliance. Our camera inspection shows you exactly which category you’re in, with no pressure either way. Call (516) 613-3035 for an exact quote - estimates are free.
We stock common DuraFlex SW and AL sections, tees, and connectors for Staten Island jobs. For specialty sizes, we source from regional distributors with typical lead times of three to seven business days. When DuraFlex factory lead times stretch, we offer HeatShield or Gelco equivalents that meet the same UL listing and performance spec - your choice, explained upfront.
A damaged DuraFlex liner can allow flue gases, including carbon monoxide, to leak into wall cavities or living space. In oil and wood systems, creosote can accumulate in gaps and create a chimney fire risk. The specific hazard depends on what’s failing - our inspection tells you exactly what you’re facing and whether it can wait. Some issues are watch-and-monitor; others need attention before the next burn. Call (516) 613-3035 and we’ll give you the straight answer.
