Staten Island’s salt-laden air - coming off New York Harbor, the Kill Van Kull, and the Arthur Kill - eats at chimney masonry faster than anywhere else in the five boroughs. We’ve restored HeatShield fireboxes in Tottenville Victorians and reparged smoke chambers in postwar Cape Cods from Great Kills to New Dorp Beach. The coating works when it’s applied right. It fails when it isn’t. We know the difference because we’ve fixed other people’s mistakes.

We’re not affiliated with or authorized by HeatShield. We’re an independent service provider that chooses to work with their materials because the cementitious formulas bond properly to compromised masonry when the prep is done correctly. That’s the standard we hold ourselves to.

Why Trust Hearthstone Chimney Co. for Your HeatShield Chimney Cleaning?

Russell Haines, our owner, grew up in Los Angeles and learned his first trade skills at Los Angeles Trade-Technical College before following work east and building Hearthstone Chimney Co. into what it is today. He and our crew have been servicing Staten Island homes for well over a decade, including older masonry fireboxes in the Tottenville area that have seen generations of hard winters. If the chimney’s sound, he’ll say so. If it isn’t, you’ll hear that too.

Our technicians are background-checked, uniformed, and trained specifically on HeatShield application protocols - surface preparation, mixing ratios, cure times, and the reinforcing fiber placement that prevents cracking under thermal cycling. We document every inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics.

We stock genuine HeatShield cementitious mix, bonding agents, and reinforcing fibers locally, so we’re not waiting on shipments while your fireplace sits out of commission. Our 90-Day Done Right Promise covers every job in writing with no arguing - if it’s not right, we come back. That’s been our way for over 42 years.

Common HeatShield Chimney Cleaning Problems We Fix in Staten Island

• Flaking firebox resurfacing from skipped bonding agent. HeatShield Firebox Resurfacing System requires a proprietary bonding agent applied to clean, dry masonry before the cementitious mix goes on. We’ve found multiple Staten Island homes where the previous contractor skipped this step, applied the mix over soot or creosote, and the new surface started peeling within two to three years. The salt air here accelerates the failure once moisture gets behind the coating.
• Smoke chamber parging cracked too thin. HeatShield Smoke Chamber Repair needs adequate thickness - typically 1/4 to 1/2 inch - to withstand the thermal expansion and contraction of regular firing. When it’s troweled on too thin, especially in the corbelled transition area, it cracks under thermal cycling and exposes the original masonry to creosote buildup and moisture intrusion. We remove the failed parging and reapply to proper depth with reinforcing fibers.
• Crown coating failure at the flue collar. HeatShield Crown Repair & Waterproofing fails prematurely when the substrate isn’t pressure-washed and primed. Water seeps behind the coating at the flue collar, freezes in Staten Island’s freeze-thaw cycles, and pushes the coating off in sheets. We always clean and prime before application, and we check the collar flashing separately.
• Firebox spalling over unremoved creosote. HeatShield resurfacing applied over glazed creosote or soot layers cannot achieve a mechanical bond. The new surface looks fine for a season, then spalls and falls away. Our cleaning protocol includes mechanical brushing and chemical treatment of glazed creosote before any resurfacing begins.
• Salt-air corrosion of underlying metal components. In Staten Island’s tidal environment, we’ve found that HeatShield applications over chase covers or metal fireboxes sometimes outlast the metal beneath them. We inspect the substrate thoroughly - if the metal is pitted through, resurfacing is a waste of your money and we’ll tell you so.

HeatShield Parts & Our Repair-vs-Replace Approach

We use genuine HeatShield materials - cementitious resurfacing mix, bonding agents, and reinforcing fibers - because generic substitutes lack the flexibility and adhesion that let the coating move with the masonry as it heats and cools. We keep these materials stocked for fast turnaround on Staten Island calls.

When damage exceeds what resurfacing can solve - spalled brick, crumbling crown substrate, or a firebox with structural cracks that compromise the wall - we recommend our Chimney Cleaning & Sweep services or rebuild or repointing instead of a patch that will fail. We’ll show you the camera footage and explain exactly why. No surprises on the bill, and no short-term fixes sold as permanent solutions. Call (516) 613-3035 and we’ll give you an honest assessment.

Our HeatShield Service Process - Step by Step

1. 1
   Diagnosis with camera inspection. We run a Level-2 camera inspection to document the condition of your firebox, smoke chamber, or crown. You see the photos. We explain what’s damaged, what’s sound, and whether HeatShield resurfacing is appropriate or if the structure needs rebuilding.
2. 2
   Surface preparation. For HeatShield to bond, the masonry must be clean, dry, and free of creosote, soot, and loose material. We mechanically brush, pressure-wash where applicable, and apply the proprietary HeatShield bonding agent. This step cannot be rushed. We’ve fixed too many jobs where it was.
3. 3
   Application and cure. We mix HeatShield cementitious resurfacing to specification, apply to proper thickness with reinforcing fibers embedded, and allow controlled cure time before any firing. Smoke chamber parging gets particular attention at the corbelled area where thermal stress concentrates.
4. 4
   Testing and documentation. After cure, we verify adhesion, check for voids or thin spots with the camera, and provide you with photos and a written report. The 90-Day Done Right Promise goes into effect. Done right - and we stand behind it.

FAQs - HeatShield Chimney Cleaning Service in Staten Island

Is Hearthstone Chimney Co. authorized by HeatShield?

No. We’re an independent HeatShield service provider in Staten Island with no manufacturer affiliation or authorization. We choose to work with HeatShield materials because their cementitious formulas perform well when applied correctly, and we answer to our customers, not to a brand.

Do you use genuine HeatShield/OEM parts?

Yes. We use genuine HeatShield cementitious resurfacing mix, bonding agents, and reinforcing fibers. Generic substitutes lack the tested flexibility and adhesion properties, and we’ve seen them fail prematurely in Staten Island’s salt-air, freeze-thaw environment.

How long does HeatShield service take?

Most HeatShield firebox resurfacing and smoke chamber repairs are completed in a single visit of four to six hours, including surface preparation and controlled cure time. Crown coatings may require additional cure time before exposure to rain. We’ll give you a clear timeline when we see the job.

What HeatShield models/series do you cover?

We service and install all HeatShield system applications: Firebox Resurfacing System, Smoke Chamber Repair, Crown Repair & Waterproofing, and Flue Tile Resurfacing. If you’re unsure which system your chimney needs, our camera inspection will show us both.

Will service void my HeatShield warranty?
