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 Fireplace Services in Elizabeth: What to Know First
We provide independent DuraFlex fireplace services in Elizabeth, from gas fireplace tune-ups to firebox repairs and insert conversions. Most DuraFlex jobs we book are completed in a single visit, and you’ll know the full cost before we start. We don’t quote low to get in the door, then find “surprise” problems - our estimate is our invoice.
This page is for Elizabeth homeowners who already have a DuraFlex liner, insert, or venting component and need a technician who understands how these systems differ from standard builder-grade setups. Whether you’re in the older homes near Peterstown or the north-end brick stacks we’ve worked on for years, we’ll tell you straight what’s wrong and what it takes to fix it. Call us at (908) 923-3159.

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wall) liners crack near the thimble in Elizabeth’s freeze-thaw cycles. The 316Ti alloy handles corrosion well, but the expansion joint at the thimble plate sees stress every January when temperatures swing forty degrees in a week. We cut back to sound metal, install a proper DuraFlex-compatible thimble adapter, and seal with high-temp silicone rated for the SW’s operating temperatures - not generic furnace cement that’ll crumble by March.
- DuraFlex AL (aluminum) liners in gas fireplace inserts develop condensation corrosion at the lower elbow. Aluminum doesn’t tolerate wet flue gases the way stainless does, and Elizabeth’s humid summers followed by heating-season startup create a perfect storm. We replace the lower elbow section with OEM DuraFlex AL or, if the homeowner plans to convert to wood later, discuss upgrading to SW during the same visit.
- DuraFlex Pro gas vent connectors separate at the snap-lock joints after years of thermal cycling. The Pro line’s twist-lock is secure when new, but repeated expansion and contraction in a busy fireplace season works the joint loose. We find the separation with our camera, reseat with fresh Pro gaskets, and add a mechanical locking band where the original design relied on friction alone.
- DuraFlex DSA (double-wall air-insulated) chimney systems lose their inner-wall support tabs in older Elizabeth installations. The 1990s-era DSA used a different tab geometry than current production; when tabs fail, the inner pipe drops and blocks draft. We fabricate a stainless support bracket in our shop or source current DuraFlex DSA components that retrofit the existing outer wall - no full system tearout needed.
- DuraFlex relining collars leak at the fireplace throat, especially in converted coal-to-gas fireplaces common in Elizabeth’s pre-war housing stock. The collar is meant to seal a round liner to a rectangular flue; in practice, the Elizabeth clay flue tiles are rarely standard size. We measure with a profile gauge, build a custom transition plate from 24-gauge stainless, and seal with DuraFlex’s own high-temp mesh and refractory mix - no improvised fiberglass packing that’ll smell on first burn.
Our DuraFlex Fireplace Services Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask what you’re burning, what you’re seeing or smelling, and when the system was last inspected. If it’s urgent - carbon monoxide alarm, visible flame rollout - we prioritize.
- 2
Level-2 camera inspection on arrival. Our technician runs a camera through the full DuraFlex liner or vent path, records the video, and shows you the footage on a tablet. You see what we see: cracks, separations, creosote buildup, or corrosion. No guesswork, no “trust me.”
- 3
Parts decision: OEM DuraFlex or quality aftermarket. We stock common DuraFlex SW elbows, Pro connectors, and DSA support components. If your repair needs a factory-only part, we order it with next-day availability from our Union County supplier and reschedule - we don’t substitute inferior fittings and hope.
- 4
The repair, documented. Our techs are background-checked, uniformed, and trained on DuraFlex’s specific torque specs and sealant requirements. We photograph before, during, and after. The work is done once, done right.
- 5
Function test and written report. We fire the system, check draft with a manometer, verify gas pressure at the valve if applicable, and give you a printed report with photos and our plain-English verdict. If the flue is sound, we say so. If it needs more work later, we tell you exactly what and why.
- 6
The 90-Day Done Right Promise. Every DuraFlex job is covered in writing. If it’s not right, we come back. No paperwork to dig up, no argument about whose fault it was.

Why Elizabeth Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been sweeping and repairing chimneys in Elizabeth since 1984. Russell Haines, our owner, spent the better part of two decades on local roofs and in local basements, from Peterstown to the north end, and built this company on thorough cleanings and straight talk. The chimney doesn’t care what you paid for the house - it just needs to be clean and clear.
Our 90-Day Done Right Promise is in writing, no arguing. Our Level-2 camera inspections end with photos you can see and a plain-English verdict. When DuraFlex parts aren’t the right solution, we also work with HeatShield refractory systems and Gelco caps and components - professional-grade materials, no builder-grade substitutes. Most jobs finish in a single visit. A square deal: no surprises on the bill.
FAQs
No, proper maintenance by a qualified technician does not void your DuraFlex warranty. We document our work with photos and written reports, which you’ll need if you ever file a warranty claim. Keep your inspection records with your home files. Call (908) 923-3159 if you’d like us to review what’s covered.
It depends on the component and the system’s age. DuraFlex SW and Pro lines have standardized dimensions where quality aftermarket fittings seal properly; older DSA systems often need factory-specific geometry. We stock both and tell you honestly which route we’d take on our own house. Call (908) 923-3159 and we’ll look up your installation.
Repair is usually the right call if the damage is localized - one cracked elbow, a separated joint, a corroded lower section. We recommend full replacement when we find multiple failure points, the liner is past its rated service life, or you’re converting fuel types and the existing alloy isn’t rated for the new application. Our camera inspection shows you exactly which situation you’re in. Call (908) 923-3159 for a free estimate.
We stock common DuraFlex SW elbows, Pro connectors, and sealants on our trucks. Less common DSA components or special-order sizes arrive next business day from our Union County supplier. We don’t start a job we can’t finish - if we need to order, we schedule the repair for when the part is in hand. Call (908) 923-3159 to check availability for your specific repair.
Gas systems can develop vent blockages or combustion problems that vent carbon monoxide into your living space. Wood and pellet systems accumulate creosote that fuels chimney fires. In Elizabeth’s older housing stock, we’ve also seen neglected DuraFlex liners deteriorate to the point where the original clay flue is exposed and damaged, turning a $300 repair into a $2,000+ relining job. Annual inspection catches this early. Call (908) 923-3159 to schedule - estimates are free.
