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 Fireplace Services in New York: What to Know First
We service HeatShield fireplace systems across New York as an independent provider, not a HeatShield-authorized shop, which means we are free to tell you when a component can be repaired instead of replaced. Most HeatShield fireplace calls we handle are scheduled within three to five business days, and every job gets a written price before any tool comes off the truck. We will not quote you over the phone without seeing the unit, and we will never start work without putting the number on paper first. If you own a HeatShield fireplace in New York and something is not firing, drafting, or sealing the way it should, call (551) 213-5548 and we will get a camera into it.

How HeatShield Products Fail - and How We Fix Them
HeatShield is primarily known for its proprietary flue and crown repair systems, but their fireplaces and inserts have their own failure patterns that we see regularly across New York. Here is what actually shows up on service calls, by line and symptom.
- HeatShield single-door cassettes with ceramic glass fog - The gaskets on these units compress after two to four seasons of regular use, especially in New York apartments where the fireplace gets almost daily burn use from October through March. When air sneaks past a flattened gasket, the glass clouds up and the burn goes inefficient. We replace the gasket with OEM-spec rope, retension the door, and check the seal with a draft test before we call it done. The fix is under $200 most of the time; the alternative, letting it seal poorly for another season, is a real drafting problem.
- HeatShield zero-clearance fireplaces with cracked refractory panels - That hairline crack running down the back brick panel is not cosmetic. It lets heat reach the steel firebox shell behind it, and eventually that shell warps. We see this a lot on the units installed in the late 2000s, particularly in older New York renovations where the original chimney was no longer safe to vent through. Panels are cheap, usually $80 to $150 each, and we replace them before the damage migrates.
- Air-tube burn baffle failure on HeatShield EPA units - The baffle sits above the fire and directs airflow for secondary combustion. On units that have been run hot or left unserviced, the air tubes burn through and you start seeing soot, weak flame, and smoke rollout. Homeowners often mistake it for a dirty chimney. It is a bad baffle. We source replacements through DuraFlex and Gelco supply channels when the original HeatShield baffle is no longer manufactured, which happens more than you would think.
- Ventless HeatShield units with clogged oxygen depletion sensor ports - These units are sensitive to dust, pet hair, and lint from city air. When the ODS ports clog, the fireplace shuts off mid-burn or will not stay lit. We clean the ODS assembly with compressed air and a fine brush, never a solvent. We also check the wall clearance and room size against the unit’s specs, because a ventless unit installed in too small a room will trip its safety sensors all season long.
- Flue liner interface failures on HeatShield fireplace-to-insert conversions - When a HeatShield fireplace gets converted to an insert, the existing flue liner has to match the insert’s output. A liner that is too large cools the exhaust gas too fast, glazing creosote onto the flue walls. We have pulled Class III creosote - the hardened, shiny, tar-like type that you cannot brush out - from conversions done by other companies. Our fix is to size the liner correctly, usually an insulated DuraFlex liner, and document it with camera footage before and after.
Our HeatShield Fireplace Services Process

- 1
Call and scheduling. You call (551) 213-5548, a live person answers, and we get your address, the fireplace type, and what you are seeing. You get a text when the tech is assigned and another when they are on the way.
- 2
Camera-scan inspection first, always. Before we touch anything, we camera the flue from the firebox to the termination. NFPA 211 Level 2 is the minimum. You see the footage while we are there, not after we have already told you what you need.
- 3
Written price and scope, in that order. Corrine Halstead’s rule is simple: the camera goes down first, then the price goes on paper. Nothing starts until you have a written scope, a written price, and a written warranty in front of you. This is Haven Standard Clause 1: Have it in writing.
- 4
OEM vs. aftermarket parts decision. If HeatShield OEM parts are available and your warranty is still active, we use them. If the OEM part is gone or backordered, we go to DuraFlex or Gelco. We will tell you which one, why, and what it does to your cost. No surprises.
- 5
Repair, test, document. We do the work, fire the unit, and test the draft. You get a photo record of the finished job to keep. Every job, every time - that is Haven Standard Clause 4, and we have done it since 2009.
- 6
365-Day Done Right Promise. If something was not done right, we make it right. It is stamped on every job under the Haven Standard, and Corrine Halstead reads every one of those reports herself before they get filed.

What moves the price in New York: building height, roof access, whether your unit requires scaffolding or a chimney ladder versus a straight-up ladder climb, and whether the OEM HeatShield part is available or we need to bring in a DuraFlex or Gelco equivalent. We itemize all of this in the written estimate, so you see the labor and parts separately. Our estimates are free, and we will hand you the number before we ask for a signature.
Why New York Homeowners Call Level Two Chimney New York for HeatShield Work

Every HeatShield call we take starts with the assumption that you have been told before that something is wrong and you do not trust the person who said it. That is why we lead with the camera, why we hand you the footage, and why we put the price in writing before anything else. We are not interested in selling you a new liner because we already have the scaffold up. We are interested in you seeing exactly what we see. It is the same reason we run live phone answer 24/7 and send a text when the tech is on the way. And it is the reason we keep materials coming through DuraFlex and Gelco channels: when a HeatShield OEM part is no longer made, you need a quality aftermarket option, not a sales pitch for a full rebuild. The camera doesn’t argue with you, and neither does the price sheet.

Frequently Asked Questions
It depends entirely on your home warranty policy and how the fireplace was installed, not on HeatShield itself. Most home warranty plans in New York exclude fireplaces entirely, and those that include them typically cap repair coverage at $500 or less. We cannot file warranty claims for you, but we will hand you a written diagnosis and photo record that you can submit to your warranty company. Call (551) 213-5548 and we will take a look.
For common components like glass gaskets, ODS assemblies for ventless units, and refractory panels, we keep stock in our New York vehicles and install them on the first visit in most cases. For model-specific HeatShield parts that are discontinued or backordered, we typically wait two to three weeks for OEM, or we shift to a DuraFlex or Gelco equivalent that we can often have in under a week. We will give you the lead time and the price before ordering anything.
Repair it if the firebox shell is still structurally sound and the flue has enough integrity to vent the unit safely. Replace it only when the steel shell is warped or the firebox has cracked through, which we confirm with camera footage and will show you on site. A new fireplace is a five-digit project in New York. Most HeatShield units we see are worth fixing. Call (551) 213-5548 for a free estimate and we will show you exactly where your unit stands.
Every service call includes a Level 2 camera-scan inspection of the flue and firebox, a full documentation of what we find, a written price before any repair work starts, the repair itself if you approve it, and a final photo record of the finished job. You also get our 365-Day Done Right Promise. It is not an add-on package; it is how we work. That is Corrine Halstead’s standard, and she has been running her crews on it since the Bronx taught her to look before she leaps.
