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.

AfterWhy Newark Homeowners Choose HeatShield Chimney Cleaning
Level Two Chimney Newark provides independent Heatshield repair in Newark, including chimney cleaning and resurfacing service throughout the city, and we’ve worked on SapPHIRE, PRO, and E-Z Fireproofing systems in this city for years. What separates our HeatShield work from a generic sweep is simple: every visit starts with an NFPA 211 Level 2 camera scan, every finding gets written down with a photo attached, and every price is on paper before anyone touches your flue. We are not affiliated with or authorized by HeatShield. We’re an independent HeatShield service provider in Newark, and we recommend and install their materials because the cerfractory formula performs well in the specific conditions Newark chimneys face.
That said, this page explains what actually goes wrong with HeatShield liners in Newark’s housing stock, how we fix it, and what it costs. If you already own a HeatShield system or you’re choosing one and want local service that understands the product line, call (862) 245-4309. We answer live, 24 hours a day.
Why Trust Level Two Chimney Newark for Your HeatShield Chimney Cleaning?
Most Newark companies that service HeatShield systems have never read the manufacturer’s application specs. We have. Corrine Halstead, who runs Level Two Chimney Newark, spent her early trade years at New York City College of Technology in Brooklyn studying masonry and ventilation before turning entirely to chimney work, and she’s serviced HeatShield-lined flues across Newark for years, including Heatshield repair in Harrison and older row houses near Branch Brook Park where original clay tile and century-old mortar make liner work more complicated than a standard suburban flue.
What that means for you is a crew that can tell the difference between a failed HeatShield application and a substrate problem underneath it. A lot of HeatShield failures we see in Newark aren’t the product’s fault. The original application was done over unprepared flue tile, or the wrong primer was used, or the creosote wasn’t fully removed before the coat went on. We don’t guess at that. We camera-scan the flue, document what we find, and write down the diagnosis before we quote a number. Clause 4 of the Haven Standard requires a photo record on every job, and that’s been our practice since 2009, because the camera doesn’t negotiate, it just shows what’s there.
We’re background-checked, uniformed, and licensed, with our license number displayed on every page. You get a text when your tech is on the way, a photo record when the job is done, and a written warranty with a written scope before work begins. That’s Haven Standard Clause 1: Have it in writing, always.
Common HeatShield Chimney Cleaning Problems We Fix in Newark
- Cracked or spalled flue tiles behind a failed HeatShield PRO liner. In Newark homes built before 1940, the original clay flue tiles have spent a century absorbing freeze-thaw cycles. When a HeatShield PRO application delaminates from the tile underneath, the old tile fragments push against the liner and create voids. We remove the failed liner, assess the substrate, and only re-coat when the brick underneath is sound enough to hold a new bond.
- Pinhole leaks at HeatShield Joint Repair System seams. This is almost always a prep failure. The Joint Repair System requires scarifying and priming the seam before application. When that step is skipped or rushed, pinholes form at the seam line and flue gases leak into the chase. In shared-wall Ironbound rowhouses, that leak isn’t just your problem, it’s your neighbor’s too, because the flue often sits against the party wall.
- Eroded HeatShield SapPHIRE coating at the smoke shelf. Acidic creosote collects at the smoke shelf in wood-burning fireplaces, and over a few seasons it eats through the cerfractory coating. This is a very common Newark finding, especially in two-family flats where the fireplace was converted to gas but the original shelf was never properly cleaned. The exposed brick behind the erosion then spalls, and you get grit falling into the firebox.
- Premature peeling of E-Z Fireproofing over glazed creosote. HeatShield E-Z Fireproofing bonds poorly to glazed creosote, and if the flue wasn’t thoroughly cleaned to bare surface before application, the coating peels within a season or two. This is a prep failure, not a product failure, and it’s the most frequent thing we see in Newark because so many flues here are old, coal-converted, and heavily loaded with hardened creosote.
- HeatShield PRO bubbling after the first winter. Bubbling is typically trapped moisture from an inadequately dried substrate, or the liner was applied over mortar joints that were still releasing water vapor. Newark’s freeze-thaw cycle and the ambient moisture from the Passaic River and Newark Bay make this worse. We see it most in chimneys that sit idle between heating seasons and never fully dry out.
BeforeAfterHeatShield Parts & Our Repair-vs-Replace Approach
We install OEM HeatShield materials: SapPHIRE or PRO cerfractory formula, and the E-Z Fireproofing and Joint Repair System products. We don’t mix brands because different cerfractory formulas expand at different rates under heat, and a hybrid liner is a warranty headache and a future failure. DuraFlex and Gelco products are available through our supply network, but we won’t spec them into a job that calls for HeatShield.
Here’s how we decide whether to repair or replace. If the existing HeatShield liner is thin or eroded in isolated spots and the substrate underneath is sound, a re-coat makes sense. If the original application was done over unprepared flue tile, or the tile has spalled so badly it’s pushing against the existing liner, a partial rebuild may outlast another coat. We tell you that plainly, with the camera images in hand, and the price for each option written down. A written price before any work starts is non-negotiable on every job, no exceptions. Call (862) 245-4309 if you want an honest read on a HeatShield liner in Newark.
Our HeatShield Service Process - Step by Step
- 1
Camera-scan diagnosis. We run a Level 2 camera down the flue and document every finding in writing with a photo or frame capture. You see what we see, and the diagnosis is on the page before any money changes hands.
- 2
Surface preparation. For HeatShield re-coats, this is where most jobs are won or lost. We scarify the existing surface, fully remove any glazed creosote, address spalled tile or failed prior liner material, and confirm moisture levels in the substrate before any application.
- 3
HeatShield application or repair. Whether it’s a SapPHIRE re-coat, a PRO application over repaired masonry, or a Joint Repair System treatment at seam locations, we install per manufacturer spec with the correct primers and the right cure window.
- 4
Post-application test. We run our draft gauge and verify the flue pulls correctly before we call the job done. On a Newark rowhouse with shared flues, we also check the neighbor’s side if the stack serves both properties.
- 5
Written warranty and photo record. You get a written scope, a written warranty, and a documented photo record of the finished work. Haven Standard Clause 4. If it’s not done right, our 365-Day Done Right Promise means we make it right.
HeatShield Products We Service & Install in Newark
- HeatShield SapPHIRE - the cerfractory coating we use most often for Newark wood-burning fireplaces that need a flue resurfacing rather than a full liner replacement.
- HeatShield PRO - the heavier-duty formulation we spec for oil-to-gas conversion flues and for chimneys serving heating appliances where the flue gas chemistry is harsher.
- HeatShield E-Z Fireproofing - for flues with sound structure that need a protective coat, applied only after we’ve verified the surface is genuinely clean and ready.
- HeatShield Joint Repair System - for sealing seam failures and preventing the pinhole leaks that plague older Newark flues.
We keep OEM HeatShield materials available locally for fast turnaround, and we can source anything we don’t carry through our supply network. 38,000-plus chimneys inspected and cleaned since 2009, including Heatshield repair in Kearny,, every one with a written price before work started and a documented record when it was done.
We Also Service These Brands
HeatShield is a strong product, but it’s not the only one we work with. We install and service DuraFlex and Gelco liners too, and we’ll recommend whichever material actually fits your flue, your appliance, and your budget. Our loyalty is to the chimney, not the label on the box.
FAQs - HeatShield Chimney Cleaning Service in Newark
No. We are an independent HeatShield service provider in Newark, not an authorized dealer or manufacturer affiliate. That independence is intentional: we recommend what’s right for your flue, not what a brand program tells us to sell. You get the same OEM HeatShield materials and manufacturer-spec installation, but our written diagnosis comes from our own camera work, not a manufacturer’s sales sheet.
Yes, we use OEM HeatShield materials, SapPHIRE and PRO cerfractory formula, and the Joint Repair System components. We don’t substitute aftermarket cerfractory from another brand because thermal expansion rates differ between formulas, and mixing them creates exactly the kind of seam failure Newark flues can’t afford. If a HeatShield product isn’t the right call for your chimney, we’ll tell you that too, in writing, with the camera images to back it up.
A full HeatShield re-coat on a typical Newark rowhouse flue, from camera scan to final draft test, takes one to two days depending on how much surface preparation the substrate needs. A flue that needs spalled tile removal and masonry repointing before the coat goes on will take longer. We’ll give you a written timeline with the written price, so you know what to expect before we start.
We service and install the SapPHIRE, PRO, E-Z Fireproofing, and Joint Repair System lines. That covers everything from a simple flue resurfacing on a wood-burning fireplace to a full PRO application over a converted heating flue in a pre-1940 Newark two-family.
If you have a valid HeatShield manufacturer warranty and the work performed on your liner was done by an independent contractor without manufacturer authorization, the warranty terms may or may not be affected depending on how the original application was documented and what the warranty language actually says. We can’t speak for the manufacturer on that. What we can do is perform all work to manufacturer spec with OEM materials and give you a complete written and photographic record, which puts you in the strongest position to make a warranty claim if one applies. Call (862) 245-4309 and we’ll walk you through what your paperwork actually says.
A HeatShield-lined chimney cleaning in Newark typically runs $180 to $340 for our Chimney Cleaning & Sweep services on a standard flue with camera scan, creosote removal, and the written photo record. If the liner needs spot repair or re-coating, that’s priced separately after the camera shows us what’s actually there, always in writing before any work begins. The price depends on flue height, condition of the existing liner, and how much creosote or spalling we’re dealing with. Call (862) 245-4309 for an exact quote, estimates are free.
