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.

AfterDuraFlex Chimney Liner & Rebuild in Ewing: What to Know First
We provide independent DuraFlex chimney liner and rebuild service in Ewing, New Jersey, with most jobs completed in a single visit and upfront pricing that matches the final invoice. A typical DuraFlex liner replacement runs $2,800-$4,500 depending on flue height and condition, and we stock common DuraFlex diameters so we’re not waiting on freight while your fireplace sits cold. This page is for Ewing homeowners who already have a DuraFlex stainless steel or flexible liner installed and need it repaired, replaced, or rebuilt into a sound chimney system. Call (856) 388-5580 - a live person answers, 24 hours a day.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW 304/316 rigid liners crack at the collar weld in Ewing’s freeze-thaw climate. Water gets between the chimney crown and the flue tile, freezes, and pushes the liner collar until the weld separates. We cut back to sound metal, install a factory-grade expansion joint, and reseal the crown with a Gelco crown coat so the joint can move without breaking again.
- DuraFlex Pro 316Ti flexible liners pancake in offset flues common in Ewing’s 1950s-1970s ranch homes near the Ewing Lawrence border. The previous installer pulled the liner too tight through a 45-degree offset, and the creases trap creosote. We pull a new Pro 316Ti with proper slack, support it at the offset with a fabricated stainless cradle, and document the before-and-after with camera photos you can see.
- DuraFlex AL29-4C condensing liner develops pinholes at the waterline in high-efficiency gas installations. The alloy resists acid but not standing water from a blocked drain tee. We replace the failed section with AL29-4C matched to the appliance BTU rating, install a proper condensate drain, and verify slope with a level - not by eye.
- DuraFlex relining tees burn through at the snout when connected to wood inserts over-fired for Ewing’s longer heating season. The 304 stainless snout can’t take the peak temps that the 316Ti body handles. We upgrade to a 316Ti or AL29-4C tee matched to the appliance, and we check the insert air control settings so it doesn’t happen again next winter.
- DuraFlex smooth-wall liners lose their top termination in the wind exposure along Bear Tavern Road and higher ground near Mercer County Community College. The standard screw-band clamp loosens, the cap lifts, and rain enters the annular space. We install a Gelco locking-band termination with storm collar and sealant bed, and we torque to spec - not “tight enough.”
Our DuraFlex Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, asks what you’re burning, what you’re seeing, and when you’re free. We don’t use apps or callback queues.
- 2
Level-2 camera inspection. Our tech runs a camera the full length of your DuraFlex liner, photographs every joint, offset, and termination, and explains what we found in plain English. You see the same images we see.
- 3
Parts decision. We match replacement sections to your existing DuraFlex series - OEM when it matters for warranty, quality aftermarket when the spec is identical and the price is fair. No substitutions you didn’t agree to.
- 4
The repair or rebuild. Background-checked, uniformed technicians complete most DuraFlex liner replacements and partial rebuilds in one visit. Full chimney rebuilds may need a second day for mortar cure.
- 5
Post-job test and documentation. We run another camera pass, perform a smoke or draft test depending on the appliance, and leave you with photos, a written verdict, and the 90-Day Done Right Promise in writing.
- 6
Cleanup and closeout. We haul away old liner sections, tarp and sweep the work area, and review the invoice with you before you pay. The number on the estimate is the number on the invoice.

Why Ewing Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been sweeping and rebuilding chimneys in Ewing long enough that some of our customers’ children now own the houses we first worked on. Russell Haines and our crew know DuraFlex products the way a mechanic knows an engine - quietly, carefully, without making things worse than they are. When a DuraFlex part is discontinued or back-ordered, we draw on our relationships with HeatShield, Gelco, and Olympia Chimney to keep your system safe and code-compliant, not to upsell you into something you don’t need.
The 90-Day Done Right Promise covers every liner and rebuild job in writing. If it’s not right, we come back. No paperwork to find, no argument about whose fault it was. We also offer a free second opinion on any written estimate you’ve received, a $89 seasonal tune-up, and a permanent 5% senior and veteran discount. Calls are answered by a live person 24 hours a day, 7 days a week - not a voicemail, not a callback queue.
FAQs
No, provided the repair uses DuraFlex-compatible materials and follows the installation manual clearances. As an independent DuraFlex service provider, we document every part number and installation detail so any future warranty claim has the paper trail it needs. We don’t cut corners on alloy grades or joint methods that would give DuraFlex a reason to deny coverage. Call (856) 388-5580 if you want us to review your original installation paperwork.
We stock common DuraFlex diameters and termination components, and our suppliers in the Mid-Atlantic region typically deliver specialty items within 3-5 business days. For Ewing homeowners heading into burning season, we prioritize liner jobs and can often complete them before the first sustained cold snap. Call (856) 388-5580 to check current stock on your specific diameter.
A localized failure - one cracked section, a burned tee, a loose termination - usually means repair. Multiple seam failures, widespread corrosion, or a liner pulled through a deteriorating clay flue that no longer supports it means replacement. Our Level-2 camera inspection shows you exactly which category you’re in, and we’ll tell you plainly when work can safely wait a season. Call (856) 388-5580 to schedule the inspection - estimates are free.
Carbon monoxide can leak through cracked seams or a failed termination, and creosote buildup in a damaged liner increases chimney fire risk. In Ewing’s older homes with tighter construction, a blocked or leaking flue also depressurizes the house and can pull combustion gases back through the water heater or furnace. We don’t scare-sell, but we do document what we find and explain what it means for your family’s safety. Call (856) 388-5580 for a camera inspection and a plain-English verdict.
We service and install DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield products. If your chimney has a mixed system - say, a DuraFlex liner with a Gelco cap or a HeatShield smoke chamber seal - we understand how those components interact and we stock parts accordingly. Call (856) 388-5580 to discuss your specific setup.
If the flue is right, the fire takes care of itself. When your DuraFlex liner isn’t right, we’ll tell you exactly what’s wrong, what it costs to fix, and how long the repair will last. No flash, no shortcuts, just the thing done correctly.
