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 White Plains, NY
Creosote removal is the process of clearing the hardened, flammable residue that wood-burning fires deposit inside your flue – residue that, left alone, becomes the leading cause of chimney fires in Westchester County homes. Most White Plains homeowners need at least a standard Chimney Cleaning & Sweep annually, but if you’ve been burning green wood, running slow fires, or haven’t had the flue inspected in a few years, you’re likely looking at heavier buildup that takes more than a brush to clear. Call us at (914) 603-1360 and a live person will pick up, any hour of the day.
Hearthstone Chimney Co. has been removing creosote from White Plains chimneys since 1984 – over 42 years of working in homes just like yours, in a climate that pushes homeowners to light their first fire before October is out. Our Chimney Cleaning & Sweep in White Plains service is the broader picture; this page is specifically about what happens when standard sweeping isn’t enough and the creosote has advanced into second- or third-degree buildup that demands a different approach.
Russell Haines leads every crew that comes through your door. Our technicians are background-checked, uniformed, and carry the tools – and the professional-grade products – to get the job done in a single visit. Every job is covered by our 90-Day Done Right Promise, in writing, no arguing.
When You Need Creosote Removal
A standard annual Level 1 Inspection and sweeping keeps most flues in good shape. But certain habits and conditions common in White Plains accelerate buildup faster than a once-a-year brush can address. Here’s when you’re likely looking at more than routine maintenance:
- You’re smelling something oily or tar-like near the fireplace. That odor – especially noticeable on humid summer days or during the first fires of fall – is third-degree creosote off-gassing. In older colonial and Tudor homes throughout White Plains, where chimneys can run 30 feet or more, that smell travels a long way before you notice it.
- You’ve had a chimney fire, even a small one. Many homeowners in the Gedney Farms and Fisher Hill neighborhoods don’t realize they’ve had one until they see glaze cracking or a tell-tale line of scorched deposits. Any chimney fire, regardless of size, warrants a full inspection and removal before the fireplace is used again.
- You burn hardwood but your fires run low and slow. Fires that smolder – common when someone banks a fire at night to stretch the heat – produce exactly the low-temperature smoke that deposits creosote most aggressively. White Plains winters being what they are, this happens in a lot of households from November through March.
- It’s been three or more seasons since your last professional sweep. Three years of typical use in a Westchester County winter – which averages more than 100 heating days – can move a flue from first-degree to second-degree buildup faster than most homeowners expect.
- You’re seeing black, flaky debris falling into the firebox. Loose flakes that drop into the firebox are a sign that first-degree creosote has dried and is beginning to scale off the liner. It looks harmless. It isn’t, because the layer underneath is often denser and stickier.
- Your Level-2 inspection photos show glazed deposits. Glazed, tar-like creosote is third-degree buildup. It’s dense enough that a standard chimney brush won’t touch it. This is the stage where chemical treatment and mechanical removal are both on the table, and where waiting makes the job – and the risk – considerably worse.
Our Creosote Removal Process
We don’t treat every job the same because every flue is different. A 1940s brick chimney in the Battle Hill neighborhood has different characteristics than a factory-built fireplace insert in a 1980s colonial off North Broadway. What follows is how we work through a creosote removal job from the first moment we arrive.
- Full inspection before we touch a brush. We start with a Level-2 camera inspection, running a live feed through the flue so we can see exactly what we’re dealing with – degree of buildup, location of deposits, condition of the liner, and whether there are any cracks or obstructions that would change how we proceed. You see the same photos we see. You get a plain-English verdict, not a list of codes.
- Setting up correctly so your home stays clean. Our technicians lay drop cloths, seal the firebox opening, and connect a HEPA-filtered vacuum system before any work begins. In White Plains homes with finished hardwood floors and period trim, protecting your space isn’t a courtesy – it’s part of the job.
- Mechanical removal matched to the buildup level. First- and second-degree creosote comes off with professional rotary brushes and hand tools. We use Copperfield brushes and rods that are sized to your specific flue dimensions – not a one-size kit pulled off a van shelf. Heavier deposits in tight masonry flues may require weighted tools or chain flail attachments to break the crust without damaging the liner.
- Chemical treatment for third-degree (glazed) creosote. When we encounter glazed buildup, mechanical tools alone can fracture the surface without removing the underlying layer. We apply a professional-grade chemical desiccant – Olympia Chimney-sourced product lines when available – that dries and depolymerizes the glaze over a defined period. A follow-up visit then clears the treated material fully. We’ll tell you upfront if your job requires two appointments; we won’t promise a one-visit resolution that isn’t realistic.
- Post-removal camera confirmation. Once the work is done, we run the camera again. This is the step most single-truck operators skip. We don’t skip it, because our 90-Day Done Right Promise is only as good as our confidence that the job was actually finished. If the camera shows residue we didn’t get, we get it.
- Written report and plain-English verdict. Before we leave, you receive a written summary of what we found, what we did, and what – if anything – needs attention in the future. If the liner needs repair, we’ll say so plainly and quote it separately. No pressure, no surprise add-ons, no paperwork fog.
Creosote Removal Pricing in White Plains
Creosote removal in White Plains typically runs between $199 and $599, depending on the degree of buildup and the specifics of your chimney. That range is honest, not a bait-and-switch floor. Here is what moves the number:
- First-degree buildup (standard sweep): $199 – $299. Dry, flaky deposits that come off with brush work. Most flues swept annually fall here.
- Second-degree buildup (tar-like, porous deposits): $299 – $449. Thicker, stickier residue requiring rotary tools and extended labor. Common in White Plains homes where fires ran low and slow over multiple seasons.
- Third-degree buildup (glazed creosote): $449 – $599, sometimes more for very long or complex flues. Requires chemical treatment and typically a follow-up visit. Homes in neighborhoods like Gedney Farms with original 1930s masonry and tall chimney stacks are the ones we see most often in this category.
- Chemical treatment products, if needed: Priced separately and quoted upfront. We won’t add this charge at the end of the job.
Our $89 Seasonal Tune-Up covers a standard Fireplace Cleaning and inspection and is a good starting point if you’re not sure where your flue stands. Seniors and veterans receive a permanent 5% discount on all services, and we offer $50 off any repair over $250. If you have a written estimate from another company, we’ll give you a free second opinion.
Every price you hear from us before the job is the price on the invoice. That’s what upfront pricing means here – not an estimate that grows once we’re in your home. Call (914) 603-1360 for a free estimate on your specific chimney. A live person will answer.
What White Plains Homeowners Should Know About Creosote
White Plains sits at roughly 300 feet above sea level with a climate that delivers cold, damp winters from late October through March. That combination matters for chimney maintenance because cooler flue temperatures – common when exterior masonry is cold and fires are just getting started – are exactly the conditions that cause smoke to condense and deposit creosote before it exits the chimney.
Homes in the North Broadway corridor and along Mamaroneck Avenue tend to have older masonry chimneys with rougher interior surfaces, and rough surfaces collect creosote faster than smooth clay tile or stainless liner. In our 42 years of work in White Plains, we’ve pulled third-degree glazed creosote out of chimneys whose owners genuinely believed they’d been maintaining them properly – because they had, just not at the frequency the flue actually required.
A note on safety: third-degree creosote is genuinely hazardous to handle and remove. The deposits are flammable, the chemical treatments require proper ventilation and handling protocols, and there is no responsible DIY approach to glazed creosote removal. If you’ve found glazed buildup on your own – or if you’ve seen a sweep describe it without offering a clear plan for removing it – call us before lighting another fire. This is the one area of chimney maintenance where the risk of a wrong step is a house fire, not just a messy cleanup.
Creosote removal is part of the broader picture of keeping your fireplace system safe. Our full home page outlines the complete range of services Hearthstone provides across Westchester County, from liner installation to crown repair, all under the same 90-Day Done Right Promise.
FAQs – Creosote Removal
How do I know if I have creosote in my chimney?
The most reliable way to know is a camera Level 2 Inspection, but there are signs you can observe yourself: a tar-like or sharp, acrid smell from the fireplace (particularly in warm, humid weather), black flakes falling into the firebox, or a noticeably restricted draw when you light a fire. In White Plains homes with older masonry chimneys, that reduced draw is often the first sign homeowners notice. If any of these apply, don’t wait for your annual sweep date – call (914) 603-1360 and we’ll take a look before the heating season gets further along.
How much does creosote removal cost in White Plains?
Creosote removal in White Plains runs $199 to $599 for most jobs. First-degree buildup (dry, flaky) lands at the lower end; third-degree glazed creosote, which requires chemical treatment in addition to mechanical removal, sits at the higher end. The specific layout of your chimney – height, liner material, and years since the last cleaning – all affect the final number. We quote it plainly before we start and the invoice matches the estimate. Call (914) 603-1360 for a free estimate on your specific flue.
Can you remove creosote in a single visit?
Most first- and second-degree creosote jobs are done in a single visit – typically two to three hours. Third-degree glazed creosote almost always requires two appointments: one to apply the chemical treatment, and a follow-up to clear the treated material once it has dried and become removable. We’ll tell you which situation you’re in before we begin, not midway through. Most of our White Plains jobs are completed in one visit because homeowners call us before buildup reaches the glazed stage.
Is creosote removal covered by any guarantee?
Yes. All creosote removal work at Hearthstone Chimney Co. is covered by our 90-Day Done Right Promise – if the job isn’t right, we come back and make it right, in writing, without paperwork or argument. Russell Haines has stood behind that promise since we started serving White Plains in 1984, and it is not a marketing phrase – it is a written commitment you receive before we leave your property.
Why White Plains Homeowners Choose Hearthstone Chimney Co.
There are a few chimney companies working Westchester County. Some are large franchise operations that rotate technicians and don’t remember your chimney from one year to the next. Some are one-truck operators whose insurance and licensing you’re taking on faith. Hearthstone is neither.
We’ve been in White Plains long enough to know that the chimneys on Soundview Avenue run differently than the ones in the newer developments off Mamaroneck. We know that a lot of homeowners in this market are dealing with chimneys built in the 1930s and 1940s that have had four or five different kinds of fuel burned in them over the decades. That history matters when you’re diagnosing buildup and deciding how to treat it.
Russell Haines built this company around the idea that the right way to do a job and the honest way to price it are the same thing. When you call, a person answers. When we give you a number, that’s the number. When we say the job is done, we’ve run the camera to confirm it. And if something isn’t right within 90 days, we come back – no paperwork, no argument.
If you’re in White Plains and you have questions about your chimney – whether it’s creosote buildup, a liner that needs attention, or just a long-overdue inspection – call (914) 603-1360. A live person will pick up, any hour. Estimates are free, and the price we quote is the price you pay.
