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.

AfterHeatShield Flue Liner Replacement: The Paterson Owner’s Guide
We stock HeatShield-compatible flue liner sections and ceramic refractory panels on our trucks, and most Paterson replacements run between $1,650 and $3,400 installed depending on the flue length, access, and whether the existing liner needs full removal or can serve as the substrate. The typical symptom that brings owners to this page: a failed level-one cleaning turned up cracked refractory panels, a separated joint, or a corroded lower section that the camera showed in detail. We identify the exact HeatShield panel size and joint configuration before quoting anything, and the written price covers the liner work, the camera re-scan, and the photo record when we’re done.
Which HeatShield Models This Applies To
HeatShield’s flue liner system comes in two installation families that matter for replacement: the cast-in-place Cerfractory system (applied as a slurry around a form) and the pre-cast ceramic refractory panel system (rigid sections assembled in the flue). Most Paterson chimneys we open up have the pre-cast panel version, and within that family there are two panel grades: standard refractory for wood-burning flues and a higher-temperature formulation for coal or heavy-use fireplaces. The compatibility gotcha owners miss: HeatShield panels are sized by flue cross-section, not by fireplace brand, so a HeatShield liner in a Majestic, a Heatilator, or a Marco fireplace all take the same panel if the flue interior measurement is the same. You’ll find the flue dimensions stamped on a small metal tag on the fireplace throat or inside the firebox opening; if it’s gone, we measure the flue with a laser and match from there.
On OEM versus aftermarket: HeatShield’s own panels are the standard we install by default, but for flues with unusual dimensions or discontinued panel sizes, we use Gelco refractory panels cut to spec. Both are ceramic refractory, both meet the same clearance and temperature requirements, and the difference is usually lead time, not longevity. We’ll tell you which one fits your chimney before you spend a dollar.
Signs Your HeatShield Flue Liner Replacement Is Failing
- Pieces of refractory panel in the firebox or on the damper. HeatShield panels are rigid; when a section cracks or spalls near the bottom, gravity brings the debris down. If you see gray, chalky fragments in the firebox after a burn, the liner has already started breaking apart.
- Visible rust staining or corrosion on the firebox walls or damper frame. Panel joints can open slightly over time, letting flue gases and moisture condense behind the liner. The rust you see is the symptom; the open joint is the cause.
- A persistent smoky smell in the house even when the damper is open. A cracked panel or separated seam changes the flue’s draft profile, pulling combustion gases back into the room instead of up and out. This is the symptom that usually starts the conversation with us.
- The fireplace suddenly draws poorly after years of working fine. HeatShield liners fail gradually, but the effect on draft can show up quickly once a panel shifts or a joint opens. A camera scan tells us the difference between a dirty cap and a structural liner failure in about ten minutes.
- You can see light or feel air movement through the flue when the damper is closed. That means the liner has separated from the surrounding flue wall or a panel has fallen out entirely. In Paterson row houses with original masonry, this is the failure mode we see most often.
BeforeAfterReplacement Cost & What’s Included
For Paterson chimneys, the installed range breaks down like this:
- Single-story flue, direct replacement of 2-3 failed panels: $1,650-$2,200
- Two-story flue, full panel replacement, standard access: $2,200-$2,900
- Flue with compromised original masonry or a full cast-in-place re-line: $2,900-$3,400
What drives the spread is rarely the panels themselves. It’s access: a straight run from the roof takes half a day; a flue that requires staging, a pull from the bottom, or removal of a damaged chimney cap adds labor hours. Our prices in Paterson run slightly higher than the South Jersey average because of older masonry and tight roof access on the row house stock near the Great Falls Historic District, where Corrine Halstead and our crew work regularly. Every quote is written before work begins, includes the full parts cost (no markup games on the panels), and carries the 365-Day Done Right Promise. If the new liner doesn’t perform, we make it right.
DIY or Call Us?
What a homeowner can safely check: visually inspect the firebox for fallen panel fragments, note any rust staining, and check whether the damper opens and closes fully. These observations help you describe the problem accurately on the phone. What a homeowner should not attempt: removing or replacing refractory panels from inside the flue. The panels sit in a fire-rated ceramic assembly; the wrong replacement piece, an incorrect joint sealant, or a panel forced into place can block the flue or create a fire hazard that a visual inspection won’t catch. Corrine Halstead and the crew have pulled failed panels out of chimneys where a previous owner had “patched” the flue with fireplace cement, and the camera told the whole story. If you suspect your HeatShield liner has failed, call (862) 356-5229 and we’ll get a camera down the flue before anyone touches anything.
FAQs
A properly installed HeatShield liner replacement typically lasts 15 to 25 years in a Paterson chimney, with the lower end applying to chimneys that see heavy wood-burning use and the upper end to fireplace chimneys used seasonally. The limiting factors in our climate are freeze-thaw cycles on the exterior masonry and moisture entering through a failed crown, which is why we always check the crown and cap before quoting a liner job.
Yes, if the damage is isolated to one or two panels and the surrounding panels are still sound and properly seated. Partial panel replacement runs $700 to $1,400 in Paterson and includes the same camera documentation and written warranty. If the damage is widespread or the panel joints have separated in multiple locations, replacement is the honest recommendation, because patching a liner that’s already failing in several places just moves the problem deeper into the flue. Call (862) 356-5229 and we’ll tell you which situation you have based on the camera footage, not a guess.
A single-story HeatShield flue liner replacement in Paterson is typically a half-day job from setup to final camera scan. Two-story flues or jobs requiring roof staging usually run a full day. We’ll give you a specific time window in the written scope before anyone starts, and you’ll have the photo record in hand before we leave the driveway.
Yes. We stock the most common HeatShield refractory panel sizes for the flue dimensions we see in Paterson chimneys: 8×8, 8×13, and 13×13, along with the matching joint sealant and panel clips. We also carry Gelco and DuraFlex components for chimneys where a flexible stainless liner or a different panel specification is the better fit. If your flue needs a size we don’t have on the truck, we’ll have it from our supplier, usually within two business days, and the quote will say so in writing.
