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 Cleaning in Ewing, NJ | Hearthstone Chimney Co.
Chimney Cleaning & Sweep - Ewing for DuraFlex systems typically runs $180-$340 for a standard sweep with Level 2 inspection, and most jobs are completed in a single visit. What sets our DuraFlex work apart in Ewing is our familiarity with the township’s post-war housing stock - ranch and Cape Cod homes whose original coal-era flues create liner sizing and creosote problems you simply don’t see in newer construction. We’re an independent DuraFlex service provider, not manufacturer-authorized, which means our loyalty is to getting your flue right, not to pushing product. Call (856) 388-5580 for a free estimate.
Why Ewing Residents Choose Us for DuraFlex Service
Russell Haines, our owner, found his way into chimney work through a masonry program at Los Angeles Trade-Technical College, then spent more than a decade learning flues up and down the East Coast. His crew has been providing our Chimney Repair in Ewing and cleaning throughout the area - including older homes near the Ewing-Lawrence border along Bear Tavern Road - long enough that some of those families now call us in for their children’s homes before the cold sets in.
We know our Duraflex services because we’ve installed and serviced them for over a decade across Mercer County. Our technicians have logged hundreds of hours on DuraFlex components, so we can diagnose liner sizing, insulation, and connection issues without guesswork. We stock genuine DuraFlex OEM parts - adapters, tees, top plates, insulation wraps - because aftermarket alternatives often carry thinner gauge steel and inconsistent diameters that compromise the liner’s UL listing.
Every inspection ends with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing, with no arguing. A live person answers the phone 24 hours a day, 7 days a week. Most jobs finish in one visit. And the number on your estimate is the number on your invoice.
Common DuraFlex Chimney Cleaning Problems We Solve in Ewing
- Premature corrosion of 304-grade liners - Ewing’s position adjacent to the Delaware River valley adds atmospheric moisture that intensifies Central New Jersey’s freeze-thaw cycle. An uninsulated DuraFlex 304 liner in an exterior chase absorbs that humidity and degrades faster than it should. We catch this during inspection and can upgrade to 316L or insulated DuraFlex before the liner fails.
- Compression or kinking at the liner top - The tight, offset flues common in 1950s-1970s Ewing ranch and Cape Cod chimneys don’t give installers much room. A kinked liner restricts draft and creates a creosote trap. Our crew knows how to assess whether a kink can be relieved or if the run needs replacement.
- Disconnected liner-to-appliance adapters - Ewing’s punishing freeze-thaw cycle spalls mortar and shifts chimney crowns. That movement works adapters loose over time, letting flue gases leak into the home. We reseat with OEM hardware and address the crown damage that caused it.
- Pinhole leaks and joint separation from improper brushing - Years of the wrong size sweep brush wear on DuraFlex seams. In Ewing’s older neighborhoods, where liners were often retrofitted into flues never designed for them, this damage shows up sooner. We match the tool to the liner and document condition with camera footage.
- Heavy glazed creosote fouling new liners - In the older Ewing neighborhoods bordering Trenton, pre-1950 clay-tile flues built for coal furnaces were never relined. When a DuraFlex liner goes in for a wood insert without proper pre-cleaning, glazed creosote quickly fouls the new system and fails inspection. We remove the old buildup first, then install.
DuraFlex Service in Ewing: What Local Conditions Mean for Your Equipment
Ewing’s residential boom ran from the 1950s through the 1970s, producing a dense stock of ranch and Cape Cod homes whose original masonry chimneys were sized and built for oil or coal furnaces. As households across the township converted to gas heat in subsequent decades, the vast majority of these flues were never relined to the smaller diameter gas appliances require. This matters for DuraFlex owners because chimney sweeps in Ewing routinely encounter improperly sized, unlined, or residue-coated flues that create both carbon monoxide risk and NJ Uniform Construction Code violations - violations that surface constantly during the active real estate turnover driven by proximity to TCNJ and Trenton.
In the Wilburtha section of Ewing, we were called to a 1960s ranch where the homeowner had a DuraFlex 316L liner installed for a new wood insert, but the flue had never been cleaned. Our crew removed nearly a gallon of glazed creosote from the original clay tiles before we could even inspect the liner; we then found the liner’s top adapter was disconnected from the cap and re-secured it with OEM DuraFlex hardware. After a Level 2 inspection and a fresh waterproofing coat on the crown, the insert drafted properly and passed the township’s code check. If the flue is right, the fire takes care of itself.

Our Ewing-area trucks carry OEM adapters, tees, top plates, and insulation wraps for same-day repairs when possible.

FAQs - DuraFlex Chimney Cleaning in Ewing
A properly sized and installed DuraFlex liner will contain flue gases and vent them safely, which directly addresses the carbon monoxide risk from an unlined or improperly sized flue. But the liner must be the correct diameter for your appliance, fully connected, and paired with a sound chimney crown and cap. In Ewing’s post-war housing, we often find original flues that are too large for modern gas appliances, so sizing is critical. Call (856) 388-5580 and we’ll measure before recommending anything.
Yes, but each flue needs its own properly sized DuraFlex liner. Shared chases in Ewing’s ranch and Cape Cod stock are common, and they complicate cleaning because cross-contamination of flue gases is a real hazard if one liner fails or connects improperly. We inspect both flues with camera equipment and document separation before any work begins. Call (856) 388-5580 for a free assessment of your chase configuration.
Ewing’s river-valley location amplifies moisture exposure, and that moisture penetrates masonry cracks, freezes, expands, and spalls brick and mortar. The resulting crown and chase damage can shift or disconnect liner tops, and uninsulated liners in exterior chases corrode faster. Insulated DuraFlex or proper chase enclosure extends life significantly. We evaluate this during every Level 2 inspection and tell you plainly whether your current setup is adequate.
Sometimes. A minor kink at the top of the liner can sometimes be relieved if the liner hasn’t been permanently deformed and the surrounding flue allows access. If the kink exceeds 20% of the run or has caused creosote accumulation that threatens the liner wall, replacement is the safer and more code-compliant path. We make this determination with camera evidence you can see, not a sales pitch. Call (856) 388-5580 for an inspection.
Yes. We stock genuine DuraFlex OEM components because aftermarket parts often have thinner gauge steel and inconsistent diameters that compromise the liner’s UL listing. This matters for insurance coverage and resale inspections in Ewing’s active market near TCNJ. We are an independent service provider - not manufacturer-authorized - so our only interest is getting your flue right with parts that fit and last.
