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.
HeatShield Chimney Liner & Rebuild in Clifton: What to Know First
HeatShield chimney liner repair and rebuild in Clifton typically runs between $1,200 and $3,400 depending on whether we’re resurfacing a liner with the HeatShield Cerfractory system or replacing it outright with a stainless steel liner. Most jobs are completed in one day, and you’ll get a written price before anything starts. As an independent HeatShield service provider, we’re not affiliated with the manufacturer, which means we call it straight: if the liner can be saved, we’ll tell you. If it can’t, we’ll show you the camera footage proving it.
This page is for Clifton homeowners who already have a HeatShield liner or Cerfractory repair and are being told it needs attention, or who had a sweep flag the liner and want a second opinion before spending real money. If that’s you, call (551) 282-9640 and Corrine Halstead or one of our techs will walk you through what to expect.
How HeatShield Products Fail - and How We Fix Them
HeatShield makes a legitimate product. The Cerfractory flue sealant system does what it claims in the right conditions. But we’ve pulled enough cameras through Clifton flues to know exactly where the product reaches its limits, and where installers cut corners.
- Cerfractory delamination at the flue tile joints. HeatShield’s Cerfractory material is a blend of ceramic and refractory cement, and it bonds to the clay tile surface. On homes in the Athenia and Richfield sections of Clifton where the chimney runs cold in winter, the freeze-thaw cycle works the bond loose over five to seven years. The material doesn’t fail first; the tile surface it’s stuck to does. Our fix depends on how much has let go. Small patches, we reapply with proper surface prep. Wide delamination means the old material has to come out and a stainless liner goes in.
- Gaps at the smoke chamber transition. HeatShield works on the vertical flue, but the smoke chamber below it is where we see problems on 1950s and 1960s Clifton homes. If the installer didn’t parge the smoke chamber before the Cerfractory was applied above it, smoke and heat spill into the gap between the chamber and the flue offset. We find this on camera because the Cerfractory looks fine, but the smoke chamber behind it is cracked. The fix is a full smoke chamber parge plus liner work, quoted as a single job so there are no surprises.
- Improper installation over glazed tile. Cerfractory won’t bond to glazed clay tile without mechanical profiling first. Some installers skip that step. The result looks fine for two seasons, then hairline cracks appear running vertically along the tile seams. When we pull the camera up a flue and see glazed tile under cracked Cerfractory, we know what happened. Fix is usually a stainless liner; there’s no reliable way to re-bond over failed glaze once the surface is compromised.
- HeatShield Joint Repair System failures at the flue offsets. On taller Clifton chimneys, the flue doesn’t run straight. There’s an offset where the vertical section shifts to clear framing. HeatShield’s joint repair works on the straight runs but we’ve seen the material fail at the offset points because the installer applied it too thick under the smoke shelf and it sagged before it cured. The camera shows a bulge and a crack right at the offset. That’s a candidate for a full liner, not a patch.
- Cerfractory over a existing sloppy liner. If a previous owner had a cheap stainless liner installed by a trunk-slammer and then someone put HeatShield over the top sections, you end up with a hybrid system where two materials expand at different rates. The thermal cycling in Clifton’s winters and humid summers eventually separates them. We see this in split-levels and raised ranches all over Clifton, and the only fix that holds is pulling both and installing one properly sized liner.
Our HeatShield Chimney Liner & Rebuild Process

Every HeatShield job in Clifton follows the same sequence. No shortcuts, no surprises, and you get documentation at every step.
- 1
Call and schedule. You call (551) 282-9640, talk to a live person, and we book a camera-scan inspection. We text you when the tech is on the way.
- 2
Level 2 camera scan. We send the camera down the flue and record everything. You see the footage on the spot, and we tell you in plain terms what we’re looking at: hairline cracks, delaminated Cerfractory, missing mortar, proper clearances.
- 3
Written scope and price. Before any work starts, we hand you a written scope that names the exact product we’ll install, the measurements, the warranty terms, and a flat price. Haven Standard Clause 1, no verbal estimates.
- 4
The work. If it’s a HeatShield respray, we prep the surface mechanically and apply per manufacturer spec. If it’s a full replacement, we pull the old liner or failed material and install the correct-sized stainless system, sourced through our buying network from HeatShield, DuraFlex, or Gelco depending on what’s actually right for your flue.
- 5
Post-install camera pass and photo record. We send the camera back down, record the finished flue, and hand you the photo record. That’s Haven Standard Clause 4, standard on every job since 2009.
- 6
Written warranty and the 365-Day Done Right Promise. If it’s not right within a year, we come back and make it right. In writing, stamped on the job.

AfterWhat HeatShield Chimney Liner & Rebuild Costs in Clifton
For a typical single-flue chimney in Clifton, here’s what HeatShield work currently runs:
- HeatShield Cerfractory respray, single flue: $1,200 to $1,800
- HeatShield Cerfractory respray with smoke chamber parge: $1,800 to $2,400
- Full stainless steel liner replacement (6-inch), single story: $2,200 to $3,400
- Full stainless liner with partial rebuild (crown and top courses): $3,000 to $4,800
- Full chimney rebuild with new liner: $5,500 and up depending on height and masonry condition
What moves the price in Clifton: flue height, roof pitch and access, whether the existing clay tile needs to be removed for a properly sized liner, and how much of the smoke chamber needs work. We name the exact price in writing before any work begins. If another company has given you a written estimate, bring it in. We’ll give you a free second opinion on whether the scope is honest. Call (551) 282-9640 and we’ll put you on the schedule.
Why Clifton Homeowners Call Level Two Chimney Clifton for HeatShield Work

Corrine Halstead grew up in Queens and learned this trade through the building trades program at CUNY Kingsborough Community College before putting in years on job sites across the metro area. She and her crew have been working Clifton for several years now, and you’ll find the van parked near the Athenia neighborhood as often as anywhere, running cameras and writing up findings before a single brush hits a flue. The camera doesn’t guess. Neither do we.
We service HeatShield because we know it, not because we’re bound to it. If a HeatShield respray is the right call, that’s what we recommend. If a DuraFlex or Gelco liner will outlast it in your particular flue, we tell you that too. Our only material loyalty is to what the camera shows and what the math says will hold. Every job ends with a written price, a written scope, and a documented photo record, and the 365-Day Done Right Promise means we’re on the hook if it’s not right. That’s not a marketing line. That’s Clause 2 of the Haven Standard, in writing on every job.
FAQs
In our experience across Clifton’s housing stock, a properly installed HeatShield Cerfractory application lasts 7 to 12 years before needing meaningful repair, while a stainless steel liner lasts 20 to 30. The freeze-thaw cycles in northeast New Jersey shorten the useful life of any surface-applied product versus an independent liner. The camera footage from your initial scan will show us which timeline applies to your flue. If you’ve been told your HeatShield liner is failing and want a straight answer on remaining life, call (551) 282-9640.
It depends entirely on where the failure is and how far it’s spread. Small areas of delamination from glazed tile can be addressed with a respray after proper surface profiling. Widespread bond failure, material that’s sagged at flue offsets, or damage behind the smoke chamber usually means full replacement is cheaper long-term than repeated patchwork. We’ll show you the camera footage and explain the condition in one plain clause, then put the decision in writing with a price for both options if applicable. Call (551) 282-9640 for an exact assessment.
HeatShield’s warranty is tied to the material, not the installer, and as an independent HeatShield service provider we follow manufacturer spec so you retain whatever coverage applies. That said, our own obligation is the 365-Day Done Right Promise, which covers the workmanship regardless of the material used. If the product fails within a year because of something we did or should have caught, we make it right at our cost. Get the full details in writing when we quote the job.
An NFPA 211 Level 2 camera scan is the only reliable way to see what’s happening inside a flue. We routinely find hairline cracks in the Cerfractory, failed bonding at tile joints, or smoke-chamber damage that a top-down flashlight looks at and misses entirely. HeatShield failures in particular start as internal bonding issues that aren’t visible from the top of the chimney. That’s why the camera-scan documentation is standard on every Level Two Clifton job, not an upsell. Clause 4 of the Haven Standard has required it since 2009.
A Cerfractory respray on a typical single-flue Clifton chimney is a same-day job, usually 3 to 5 hours from setup to cleanup. A full stainless liner replacement with smoke chamber work is also a one-day job in most cases. Full rebuilds with masonry take longer, and we’ll put a realistic timeline in writing before we start. We text you when the tech is on the way, and the photo record plus written warranty are in your hands before we leave the property.
