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 Huntington Homeowners Choose HeatShield Chimney Cleaning
We provide independent HeatShield chimney cleaning and resurfacing service throughout Huntington, NY, specializing in the ceramic flue restoration system that many North Shore homeowners rely on to avoid full liner replacement. Our crew handles everything from routine maintenance sweeps on HeatShield-coated flues to complete removal and reapplication when the original job was done poorly. Call us at (631) 776-4075 to schedule a Level 2 inspection with photos you can see and a plain-English verdict on whether your HeatShield lining is still protecting your home.
Huntington’s position on the North Shore facing Huntington Bay and Long Island Sound exposes chimneys to persistent salt-laden marine air that accelerates mortar joint erosion and metal flashing corrosion far faster than comparable homes just a few miles inland in central Suffolk County. The large inventory of pre-1960 Colonials and Cape Cods throughout the village and waterfront hamlets - many with multi-flue chimneys originally engineered for coal or fuel-oil furnaces - means a significant share of local homes are running modern gas appliances through oversized, improperly lined flues, a combination that creates both creosote and CO risk and routinely fails Suffolk County inspection. HeatShield’s ceramic resurfacing system was designed precisely for this scenario: restoring a clay tile flue to a smooth, sealed surface without the cost and masonry disruption of a stainless-steel liner install.
We’re not affiliated with or authorized by HeatShield. We’re an independent service provider that has restored hundreds of HeatShield chimney flues across Huntington and Long Island’s North Shore, mastering the brand’s ceramic-based resurfacing process in all its formulations. We’ve seen every failure mode this product can exhibit after years of service. That independence matters because it means we evaluate your flue honestly - if HeatShield is the right fix, we’ll say so; if a stainless-steel liner from DuraFlex or Gelco makes more sense, we’ll tell you that plainly too.
Why Trust Hearthstone Chimney Co. for Your HeatShield Chimney Cleaning?
Russell Haines, our owner, grew up in Los Angeles but it’s the older homes along Huntington’s West Neck Road where he’s spent the better part of the last decade reading fireboxes and flue liners that have a lot of years behind them. He learned the trade at Los Angeles Trade-Technical College, came up doing the kind of repetitive, unglamorous work that teaches you more than any classroom can, and has been cleaning and inspecting chimneys professionally for over twenty years. He keeps a small wood stove at home, which he says is the only honest way to stay accountable to the work. That same standard runs through our crew.
We know HeatShield’s product line cold. The standard ceramic mix, the 2000°F high-temp formula for wood-burning applications that run especially hot, and the Air-Eze formulation designed specifically for gas flues - we’ve applied, removed, and reapplied all three across every kind of Huntington chimney you can find. We understand the prep work that separates a coating that lasts from one that flakes inside two years. We stock HeatShield’s genuine two-part ceramic mix and proprietary additives on our trucks, and we carry the specialty brushes and inflation castings needed for proper application.
Our Level 2 camera inspections end with photos you can see and a plain-English verdict. No engineer-speak, no scare tactics. If your HeatShield lining is sound, we’ll document it. If it’s failing, we’ll show you exactly where and explain why. Our 90-Day Done Right Promise covers every job in writing with no arguing - if it’s not right, we make it right. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it.
Common HeatShield Chimney Cleaning Problems We Fix in Huntington
- Flaking or delamination of the ceramic coating - This happens when HeatShield was applied over a dirty or creosote-contaminated flue surface. The ceramic mix needs clean, sound clay tile to bond to. We see this constantly on Huntington chimneys where a previous sweep skipped the mechanical cleaning step or where the homeowner burned unseasoned oak from local tree services, building up glazed creosote that no brush could fully remove. Our crew removes the failed coating entirely, sweeps the flue with rotary chains and whips, then reapplies only after a clean surface is verified by camera.
- Hairline cracks that reappear at mortar joints - Thermal cycling in Huntington’s older chimneys is brutal. The freeze-thaw cycle along the North Shore, intensified by high ambient humidity off Huntington Bay, drives water into hairline mortar cracks that expand and fracture masonry faster than drier inland climates. When HeatShield is applied over a chimney with active joint movement and no expansion accommodation, cracks reopen within 18-24 months. We address the underlying masonry first, then specify the correct HeatShield formulation and thickness for the expected thermal range.
- Bond failure and spalling from moisture intrusion - A missing chimney cap or crown crack lets water sit behind the ceramic layer, and HeatShield is not designed to be a waterproofing system. It’s a flue lining. Technicians working the Lloyd Harbor and Centerport waterfront regularly find that salt air has eaten the repointing mortar on chimney stacks down to near-void joints within 8-10 years of a repair - a timeline that surprises homeowners used to mainland standards. Before we ever mix HeatShield, we repair the crown, verify cap and flashing integrity, and specify salt-resistant mortar mixes where the chimney faces direct marine exposure.
- Complete separation at the smoke chamber transition - This is the telltale sign of the wrong mix or thickness applied during a past repair. The smoke chamber is the most complex geometry in any flue, and HeatShield requires precise application technique there. Too thin, and it won’t insulate; too thick, and it sags before curing. We’ve removed and re-done smoke chamber coatings where the previous installer clearly rushed the inflation casting or used an expired batch of ceramic mix. Our crew checks batch dates and mixes fresh on site.
- Creosote accumulation on HeatShield surfaces - A properly applied HeatShield coating should present a smooth, non-porous surface that resists creosote adhesion better than rough clay tile. But when the surface is uneven or partially failed, creosote traps in the irregularities and builds to hazardous levels. Huntington’s older housing stock, with substantial concentrations of 1920s-1950s Colonials and Cape Cods originally built for coal, often has flue sizing that encourages sluggish draft and incomplete combustion. We remove the creosote, assess whether the HeatShield surface can be restored, and advise honestly on whether the underlying flue geometry is part of the problem.
HeatShield Parts & Our Repair-vs-Replace Approach
We use HeatShield’s genuine two-part ceramic mix and proprietary additives - the same materials the manufacturer specifies, not generic refractory cement dressed up to look similar. Our trucks carry standard mix, 2000°F high-temp formula, and Air-Eze for gas applications, plus the inflation casting bladders and specialty tools that proper application requires.
But we’re plain about this: when the flue is too far gone for resurfacing, we recommend a stainless-steel liner instead of patch repairs. HeatShield is an excellent product in the right application. It is not a miracle. If your clay tiles are shifting, if the flue is actively leaking combustion gases into surrounding masonry, or if the chimney structure itself is compromised, we’ll tell you. No coating, however well applied, fixes a chimney that needs rebuilding. We’ll always tell you if a HeatShield repair will realistically last or if replacement is the smarter long-term investment. A square deal: no surprises on the bill.
Call (631) 776-4075 and we’ll walk you through what your flue actually needs.
Our HeatShield Service Process - Step by Step
- 1
Diagnosis with Level 2 camera inspection. We run a high-resolution camera the full length of your flue, documenting every crack, delamination, and creosote deposit. You see the photos. We explain what we’re looking at in plain English. If we find a failed HeatShield application, we note the failure mode - flaking, cracking, bond loss, or separation - because that determines the repair strategy.
- 2
Mechanical cleaning and surface prep. Failed coating comes off. Creosote comes out. We use rotary chains, poly whips, and hand tools as appropriate for your flue’s condition. The surface must be clean, dry, and structurally sound before any new HeatShield touches it. We repair crown cracks and verify cap function at this stage - moisture is the enemy of every ceramic coating.
- 3
Repair or reapplication. For sound flues needing resurfacing, we apply HeatShield using the manufacturer’s specified inflation casting method, ensuring uniform thickness and complete coverage at joints and transitions. For smoke chambers, we use the specialized techniques this geometry demands. We select the correct formulation: standard mix for typical wood-burning, 2000°F for high-output appliances, Air-Eze for gas.
- 4
Post-application testing and documentation. We camera the flue again to verify coverage quality. We perform a smoke test or draft test as appropriate to confirm proper venting. You receive photos, our written verdict, and documentation of the work performed. Our 90-Day Done Right Promise covers the job in writing with no arguing.
Our crew was called to a 1920s colonial near Huntington Village where the homeowner had a HeatShield resurfacing done five years ago by another company. We found the ceramic layer flaking off in sheets above the damper, with heavy creosote hiding underneath. We removed the failed coating, swept the flue, and reapplied HeatShield’s standard mix after repairing a cracked crown that had been letting water in for years. Done right - and we stand behind it.

FAQs - HeatShield Chimney Cleaning Service in Huntington
No. We are an independent HeatShield service provider, not affiliated with or authorized by the manufacturer. We’ve restored hundreds of HeatShield flues across Huntington and Long Island’s North Shore through hands-on experience with the product’s full formulation range. Our independence means we evaluate your flue without manufacturer bias - if HeatShield is right for your situation, we’ll say so; if a stainless-steel liner from DuraFlex or Gelco is the better long-term solution, we’ll tell you that plainly.
Yes. We use HeatShield’s genuine two-part ceramic mix and proprietary additives, the same materials specified by the manufacturer for proper bonding and heat resistance. We do not substitute generic refractory cements or aftermarket equivalents that lack the controlled particle size and bonding agents that make HeatShield perform. Our trucks stock standard mix, 2000°F high-temp formula, and Air-Eze for gas flues.
Most HeatShield cleaning, inspection, and repair jobs are completed in a single visit of three to five hours. Removal of a failed previous application adds time, as does crown repair or masonry work that must precede recoating. We’ll give you a clear time estimate when we see your flue condition during the initial camera inspection. Call (631) 776-4075 to schedule - estimates are free.
We service and install all HeatShield ceramic resurfacing formulations: the standard mix for general clay tile restoration, the 2000°F high-temp formula for wood-burning applications with sustained high heat output, and HeatShield Air-Eze specifically engineered for gas fireplace and furnace flues. We also handle removal and reapplication of previous HeatShield work done by other contractors, which represents a significant portion of our Heatshield in Oyster Bay and Huntington call volume.
HeatShield warranties are typically issued by the installing contractor and cover defects in application. As an independent provider, our work does not extend or transfer manufacturer warranties, but our own 90-Day Done Right Promise covers every job we perform in writing with no arguing. If you’re concerned about warranty status, we can assess whether your existing coating was properly applied and document its condition for your records. For warranty claims on original installation, you would need to contact the contractor who performed the work.
HeatShield chimney cleaning and inspection in Huntington typically runs between $275 and $450 for a standard sweep and Level 2 camera evaluation of an existing coating. Removal and reapplication of a failed HeatShield surface ranges from $1,800 to $3,200 depending on flue height, accessibility, and whether crown or masonry repair is needed beforehand. We provide no-hassle upfront pricing before any work begins - the number on the estimate is the number on the invoice. Call (631) 776-4075 for an exact quote on your specific flue; estimates are free.
The signs are usually visible during a Level 2 camera inspection: flaking or peeling ceramic material, hairline cracks reopening at mortar joints, discoloration from moisture behind the coating, or pieces of HeatShield material visible in the firebox or cleanout. You may also notice draft problems, smoke odor, or increased creosote buildup. We document everything with photos you can see and give you a plain-English verdict on whether repair or replacement is warranted. Call (631) 776-4075 to schedule.
Sometimes. HeatShield is designed to resurface sound clay tile with minor cracking, not to structurally repair a flue with shifting, spalling, or missing tiles. We evaluate each flue individually. Hairline cracks in otherwise stable tile are good candidates. Active tile movement, gaps large enough to see daylight through, or tiles that sound hollow when tapped usually mean a stainless-steel liner is the appropriate solution. We’ll show you the camera footage and explain where your flue falls on that spectrum.
Yes, but only with the correct formulation. HeatShield Air-Eze is specifically engineered for gas appliance flues, with properties matched to the lower temperatures and different condensation patterns of gas combustion. Using standard HeatShield mix or high-temp formula in a gas flue is a mismatch that leads to premature failure. We specify Air-Eze for all gas applications and verify proper sizing for your appliance’s BTU output and draft requirements.
A properly applied HeatShield coating on a well-maintained chimney should last 15 to 20 years. In Huntington’s marine climate, that lifespan depends heavily on keeping water out - intact crown, proper cap, sound flashing. The freeze-thaw cycle along the North Shore, intensified by humidity off Huntington Bay, will find any weakness in your chimney’s weather protection and exploit it. Annual inspection and sweeping are genuinely necessary here, not just precautionary. We’ll be there when we say.
No. We’re straight with people - if a chimney needs a repair, we say so plainly and price it fairly; if it doesn’t, we’ll tell you that too. Russell Haines is known around Huntington for exactly this. HeatShield is less expensive than a stainless-steel liner, and when your flue is a good candidate, it’s the right recommendation. We only advise liner replacement when the flue structure won’t support a coating long-term or when your heating appliance requires the performance characteristics only metal can provide. Photos you can see, a plain-English verdict. That’s how we work.
