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 Bloomfield, NJ | Top Hat Chimney
Top Hat Chimney provides independent Chimney Cleaning & Sweep in Bloomfield, DuraFlex inspection, and liner service across Bloomfield, NJ. We’re not factory-affiliated or authorized by DuraFlex, and that’s exactly why homeowners call us: we diagnose what’s actually happening inside your flue without a sales script. What makes our DuraFlex work different here is simple. Bloomfield’s pre-war housing stock carries a specific oil-to-gas conversion legacy that leaves DuraFlex liners vulnerable to acidic condensate and hidden flue damage most companies never look for. Call (551) 368-8859 for a straight answer and a free estimate.
Why Bloomfield Residents Choose Us for DuraFlex Service
Wendell Pike founded Top Hat Chimney back in 1999, and he’s been inside more Bloomfield flues than he can count. He learned the trade at Southwestern College in Chula Vista, then spent years apprenticing under guys who treated every liner like it mattered, because it does. These days Wendell and his crew know the older rowhouses and two-family brick stacks along Bloomfield’s side streets as well as any block they’ve ever swept. If it doesn’t need doing, he’ll tell you so.
We work on DuraFlex sales & service every week, but we answer to you, not a manufacturer. That means we stock genuine DuraFlex components, we know which liner models fail in which flue conditions, and we never upsell a replacement when a sweep and a camera inspection will do. Bloomfield homeowners get a live person on the phone around the clock, upfront pricing before a single tool comes off the truck, and a 90-Day Done Right Promise in writing on every job.
Common DuraFlex Chimney Cleaning Problems We Solve in Bloomfield
Here’s what we actually find when we open up DuraFlex liners in Bloomfield homes:
- Corrosion pitting in DuraFlex 316L liners. Bloomfield’s oil-to-gas conversions left orphaned gas water heaters venting into flues sized for old oil burners. The oversized flue cools exhaust too fast, producing acidic condensate that eats pinholes through 316L stainless. We see this weekly in the two-family corridors off Broad Street.
- Torn liner walls from previous metal-brush sweeps. A homeowner or a prior company runs a steel brush down a DuraFlex liner, tears the inner wall, and creates creosote traps that build up fast. The liner looks fine from the top, but the camera tells another story.
- Missing or undersized rain caps and top plates. Bloomfield’s freeze-thaw cycle, with temperatures cycling above and below freezing from November through March, pushes water into every gap. An improper termination lets rain and debris straight into the liner, accelerates rust, and invites animals into abandoned flue cavities.
- Liner ovalization or collapse in tight multi-flue stacks. Along Broad Street and the Watsessing corridor, single brick stacks carry two or three flues. When a DuraFlex liner gets forced through a tight, deteriorated flue, it can ovalize, restrict draft, and backdraft carbon monoxide into living space. That’s a stop-everything repair.
- Abandoned flue voids destabilizing active liners. When Bloomfield buildings converted from individual oil burners to a single gas system, top-floor flues were often capped and abandoned. The uncapped interior voids collect water and debris, and that internal masonry erosion shifts the brick around your active DuraFlex liner. Adjacent liners crack, separate, and leak. It’s the hidden problem no routine sweep catches.
DuraFlex Service in Bloomfield: What Local Conditions Mean for Your Equipment
Bloomfield’s dense concentration of pre-WWII housing, primarily 1910s through 1940s two- and three-family brick homes, means a large share of chimneys were originally sized for oil-fired boilers and have since been converted to gas. That leaves oversized, unlined or under-lined flues that draft poorly, accumulate acidic condensate, and pose real carbon monoxide risk. In the multi-family neighborhoods along Broad Street and the Watsessing corridor specifically, we frequently find a single exterior chimney stack with two or three separate flues where the top-floor unit’s flue was capped and abandoned when the building switched to one gas system. The uncapped void lets water, debris, and animals into the masonry from the inside. That internal erosion doesn’t just damage the abandoned flue. It destabilizes the brick wythe shared by your active DuraFlex liner, which means a liner that tested fine last year can shift and separate by this winter. No generic chimney cleaning page will tell you that, and neither will a factory brochure. We will, because we’re the ones pulling the camera back out of those flues every week.
One job sticks with us. A two-family brick home on Broad Street in Bloomfield came in with the top-floor tenant’s gas boiler venting through a DuraFlex 316L liner. That liner was pitted with acidic condensate, and the abandoned third flue was uncapped, letting rain soak the shared brick wythe. We installed a new DuraFlex liner with a proper rain cap and a multi-flue top plate, then waterproofed the stack to stop the internal masonry erosion as part of our Chimney Repair in Bloomfield. The tenant’s CO readings dropped, and the landlord got camera footage of every fix before we left.
DuraFlex Models & Products We Service in Bloomfield
We service the full range of DuraFlex liner products in Bloomfield homes: the DuraFlex 316L Flexible Chimney Liner, the DuraFlex Pro 316Ti Liner, the DuraFlex 304L Flexible Liner, and the DuraFlex Aluminum Liner for gas-only applications. We always replace liners and components with genuine DuraFlex parts. Tee bodies, rain caps, top plates, connectors, everything. That keeps the UL listing intact and the fit correct. When an older, deformed liner has patching costs that exceed 50% of a new liner, we push for full replacement to restore safe venting. No aftermarket parts, no shortcuts, no “close enough” fittings.
DuraFlex Service Pricing in Bloomfield
DuraFlex chimney cleaning in Bloomfield typically runs between $180 and $340 for a standard sweep and inspection. Camera inspection adds $75 to $150, and a Level 2 inspection, the one you want after a conversion or before buying a multi-family home, runs $250 to $450. If we find liner damage, repairs usually start around $300, while a full DuraFlex reline lands between $1,800 and $4,500 depending on flue length and access. What drives the cost in Bloomfield specifically is height and stack complexity: multi-flue brick stacks from the 1920s take more time to access safely. We have standing offers that help: $40 off any repair over $200, a free second opinion on any competing written estimate, no trip charge inside the county, and 10% off always for seniors and veterans. Call (551) 368-8859 for an exact quote, and you’ll get the same number on the invoice.

FAQs - DuraFlex Chimney Cleaning in Bloomfield
Probably not, and the reason is specific to Bloomfield. Your gas boiler vents into a flue originally sized for an oil burner. The oversized flue cools exhaust too fast, creating acidic condensate that pits even a DuraFlex 316L liner. The only way to know is a camera inspection. If you haven’t had one since the conversion, call (551) 368-8859 and we’ll show you the footage ourselves.
Small tears can sometimes be patched with genuine DuraFlex components, but if the repair cost exceeds half the price of a new liner, we replace it. Pitted 316L liners exposed to years of acidic condensate usually need replacement. The camera verdict comes with plain-English advice either way, and we’ll tell you if you can safely wait another season.
Yes. The uncapped abandoned flue lets water, debris, and animals into the masonry from the inside, which erodes the brick wythe shared by your active liner. That internal erosion can shift and separate the liner even with no visible damage from the top. This is one of the most common hidden problems we find along Broad Street and the Watsessing corridor. Call (551) 368-8859 and we’ll camera the whole stack, not just the active flue.
Once a year, burn or no burn. Chimneys break in the off-season too, and first-degree creosote is a brush job. Third-degree is a glaze. In Bloomfield’s freeze-thaw cycle, moisture gets into any exposed gap and accelerates liner rust well before your first fire of the season. A yearly sweep catches it early.
We back every job with our 90-Day Done Right Promise in writing. If the work isn’t right, one call brings Wendell and his crew back at no additional cost. We’re independent, not factory-affiliated, which means the warranty comes from the people who did the work and answer the phone around the clock. That’s stronger than a sticker.
