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.

AfterCreosote Removal in Hempstead, NY
Creosote removal in Hempstead, NY typically runs between $150 and $600 depending on how many degrees of buildup your flue has accumulated and how long it has been since your last Chimney Cleaning & Sweep. Most jobs Wendell and his crew handle are finished in a single visit, same day. If you are smelling something sharp and tarry from your fireplace, or you notice a dark, shiny glaze coating the inside of your firebox, do not wait on it.
Creosote is the byproduct of incomplete combustion – wood smoke that cools before it fully exits the flue and condenses on the liner wall. In Hempstead, where a lot of older homes run oil-fired systems and wood-burning fireplaces through a Long Island winter that can push a chimney hard, the buildup happens faster than most homeowners expect. First-degree creosote is a brush job. Third-degree is a glaze – catch it early, and a standard chimney sweep handles it. Let it go, and you are looking at a chemical treatment or, in the worst cases, a liner replacement.
Top Hat Chimney has been working chimneys in Hempstead and the surrounding Nassau County communities since 1999. Wendell Pike founded this company and still runs it – if you call (516) 963-1068 tonight at ten, there is a real chance he answers. Everything we do falls under our broader Chimney Cleaning & Sweep in Hempstead service, and creosote removal is the part of that work that matters most for your family’s safety.
When You Need Creosote Removal
Creosote does not announce itself the way a cracked crown or a missing cap does. It builds quietly. Here are the situations where Hempstead homeowners should stop waiting and make the call:
- You can smell something acrid, smoky, or tarry when the fireplace is not in use. That odor – especially on humid Long Island summer days – is third-degree creosote baking off the walls. Humidity activates it, and Hempstead sits close enough to the water that this is a common complaint we hear starting in June.
- It has been more than a year since your last sweep. The Chimney Safety Institute of America and the NFPA both recommend an annual inspection. Your flue does not care how many fires you actually built last season – creosote deposits and moisture damage accumulate even in a chimney that barely got used.
- You are seeing dark, shiny patches inside the firebox or on the damper. That glaze is second- or third-degree creosote. First-degree is dusty and gray. The moment it gets shiny, you need more than a brush.
- Your fires burn sluggishly, smoke rolls back into the room, or you are going through more wood than usual. Heavy creosote narrows the effective diameter of your flue and chokes the draft. Homes in the Uniondale and Garden City Park edges of Hempstead with older masonry chimneys and clay tile liners are especially prone to this because the tile joints attract buildup at the seams.
- You have just bought a house in Hempstead and do not know the sweep history. We see this constantly. Someone buys a split-level in West Hempstead or a cape in Franklin Square, they are told the chimney “was cleaned two years ago” by whoever, and when Wendell drops the camera in there it looks like the inside of a smoker. Get a baseline inspection before you light the first fire.
- You had a chimney fire, even a small one. Many chimney fires in Hempstead go undetected – a brief, loud roar, a smell, and then nothing obvious. But the creosote that caused it is still there, and the liner may be compromised. A camera inspection after any suspected chimney fire is not optional.
Our Creosote Removal Process
Wendell and his crew work Hempstead and Nassau County the same way every time. No shortcuts, no guessing. Here is what happens from the moment we arrive at your door:
- Pre-work inspection with a chimney camera. Before a single brush comes off the truck, the sweep runs a video camera down your flue from the top and inspects the firebox, smoke chamber, and damper from below. You see the footage. You get a plain-English verdict – what degree of creosote you have, whether there is any structural concern, and exactly what needs to happen. No surprises on the invoice.
- Prep and containment. Drop cloths go down, the area around the firebox is sealed, and the work zone is set up so that ash and debris do not end up in your living room. In Hempstead’s older homes – especially the postwar colonials common in the East Meadow and Elmont sections – the fireplaces are often original masonry, which means more dust potential. We take the prep seriously.
- First- and second-degree removal with rotary brushes. Standard creosote – the dusty, flaky, or crunchy deposits – comes off with professional-grade rotary brush systems run from the top down. This is the core of a chimney sweep, and when the buildup is caught early, it is all you need.
- Chemical treatment for third-degree creosote (glazed deposits). Glazed creosote does not yield to a brush. We apply a professional-grade creosote modifier – applied carefully to break down the hardened glaze so it can be brushed out or expelled safely during subsequent fires. This step is why it matters that the sweep who shows up knows what they are looking at. Using a brush alone on a glazed flue pushes the problem around; it does not solve it. We use products we trust, including Gelco-compatible chemical treatments where applicable, and we explain what we are applying and why before we open the container.
- Post-removal brush pass and vacuuming. After the chemical treatment has done its work, a final brush pass clears loosened material, and the crew vacuums the firebox, smoke shelf, and surrounding area. We do not leave your living room smelling like the inside of a flue.
- Final camera confirmation and written report. The camera goes back down. You see the before-and-after footage side by side. Wendell or the sweep on-site gives you a written summary of what was found, what was done, and whether any follow-up work – a liner repair, a crown patch, anything – is genuinely needed. That report is yours to keep, and the 90-Day Done Right Promise is stamped on it: if something is not right, one call brings us back at no additional cost.
Creosote Removal Pricing in Hempstead
Creosote removal in Hempstead runs across a pretty wide range depending on what degree of buildup you have and what your flue looks like. Here is an honest breakdown of what most homeowners in Nassau County actually pay:
| Creosote Level | What It Means | Typical Price Range |
|---|---|---|
| First-degree (dusty/flaky) | Standard sweep removes it; usually caught during annual cleaning | $150 – $250 |
| Second-degree (crunchy/tar-like) | Heavier brush work, possibly two passes; more time in the flue | $250 – $400 |
| Third-degree (glazed) | Chemical treatment required before brushing; multiple visits sometimes needed | $400 – $600+ |
| Camera inspection (if standalone) | Video inspection with written report, included free with cleaning | $99 – $149 standalone |
A few things affect where your job lands in those ranges. Flue height matters – a two-story chimney in a West Hempstead colonial takes longer to brush than a single-story ranch. The liner material matters too: clay tile liners hold glazed creosote in the joints differently than stainless steel flex liners. And the last time your chimney was cleaned matters most of all. A Hempstead homeowner who cleans every year stays in that first-degree range. Someone who goes four or five years without a sweep is almost certainly looking at second- or third-degree work.
You get the price before any work starts. No exceptions. That is how we have operated since 1999, and it is why homeowners in Hempstead call us back instead of shopping around every fall.
If your job involves a repair over $200 – a liner patch, a smoke chamber repair, a crown rebuild – you get $40 off automatically. Seniors and veterans always get 10% off. And if you have a competing written estimate from another company, we will give you a free second opinion.

FAQs – Creosote Removal
How much does creosote removal cost in Hempstead, NY?
Creosote removal in Hempstead typically costs between $150 and $600. First-degree buildup – the kind caught during a routine annual sweep – usually falls in the $150-$250 range. Third-degree glazed creosote, which needs chemical treatment before it can be brushed out, runs $400 to $600 or more depending on flue length and how long the deposit has been accumulating. Call (516) 963-1068 for a free estimate – we give you the number before a single tool comes off the truck.
Is creosote removal dangerous? Can I do it myself?
Creosote removal – especially third-degree glazed creosote – is genuinely hazardous work and should not be a DIY project. Glazed creosote is highly flammable, and disturbing it without the right chemical treatment and containment can trigger a chimney fire. Working at height on a roof adds its own serious risk. The rotary brush systems professionals use apply controlled downward pressure through a sealed system; improvised tools do not behave the same way and can crack clay tile liners or dislodge sections of a deteriorating flue. First-degree dusty buildup is lower-risk, but you still need a camera to confirm what degree you are actually dealing with before you start. Let a trained sweep make that call.
How often does creosote need to be removed from a Hempstead chimney?
At minimum, once a year – burn season or not. The NFPA recommends annual inspection and cleaning for every fireplace in use, and Long Island’s climate gives creosote an extra reason to be a concern: the humidity off the Sound accelerates the transition from first-degree to second-degree deposits, especially in chimneys that run cooler fires or burn wood that was not fully seasoned. Hempstead homeowners who burn regularly through a full winter should not skip years. Those who use the fireplace occasionally – a few fires at Thanksgiving and Christmas – can often maintain clean flues with a single annual visit, but they still need the camera inspection to confirm it.
What happens if glazed creosote is not removed?
Glazed, third-degree creosote left in a flue is one of the leading causes of house fires in Nassau County. It ignites at around 1,100 degrees Fahrenheit – a temperature a wood fire in a blocked flue can reach easily. Once it catches, a chimney fire burns far hotter than the liner was designed to handle, which cracks clay tiles, warps stainless liners, and can transfer heat directly to wood framing around the flue. Beyond fire risk, a heavily glazed flue restricts airflow to the point where carbon monoxide can back-draft into the living space. If you know your flue has not been cleaned in two or more years and you are burning wood, get the camera in there before the next fire. Call (516) 963-1068 and we will get Wendell or one of his crew out to take a look.
Why Hempstead Homeowners Call Top Hat Chimney
There is no shortage of chimney companies running ads in Nassau County. Most of them quote a low number on the phone and adjust it once they are in your house. That pattern is something Hempstead homeowners have told us about for years – a call to a company with a toll-free number, a price that changed at the door, and no one answerable when something was wrong six weeks later.
Top Hat Chimney is not that. Wendell Pike started this company in 1999, works the same communities he has always worked, and puts his name on every invoice. The home page for Top Hat Chimney has the address, the license number, and the phone number in plain sight – because a company that runs into its customers at the grocery store on Saturday has to stand behind what it did on Tuesday.
The 90-Day Done Right Promise is not marketing language. It is a written commitment on every completed job: if the work is not right, one call brings us back at no charge. We have honored it hundreds of times over 29 years, and we have never charged a return visit when the original work was the issue.

If you are a Hempstead homeowner who has not had your flue looked at in a while, or you moved in recently and do not know the sweep history, do not wait for the first cold snap to find out what is in there. The camera footage and a plain-English verdict – every time, no exceptions.
