Frequently Asked Questions - Chimney Cleaning in New York, NY
Straight answers to the questions New York homeowners ask us most about chimney sweeping, inspections, and repairs. If you don't see your question here, call (315) 644-2982 and we'll talk it through.
Pricing & Cost FAQs
A standard chimney cleaning in New York typically runs $180 to $340, depending on the flue size, the amount of creosote buildup, and whether you have a single fireplace or a multi-flue chimney. Our price includes the sweep itself, a camera inspection, and a written report with photos. You get a written price before any work starts, so there's no surprise at the door. If we find something that needs attention, we'll show you the camera footage and explain what's urgent and what can wait. Call (315) 644-2982 for an exact quote.
Every sweep we do includes a full flue cleaning, a visual inspection of the firebox, damper, cap, and crown, plus a camera scan of the flue interior. We lay drop cloths, run a HEPA vacuum, and leave the hearth cleaner than we found it. Afterward, you get a written report with photos showing exactly what we saw. That's the whole point of the way we work: you should never be asked to trust someone's word about the inside of a chimney you can't see. Call (315) 644-2982 to schedule.
No. The camera inspection is part of every sweep, not an add-on. In a city like New York where many chimneys are 80, 100, or 120 years old, you need to see what's actually inside the flue before anyone tells you to spend money on repairs. We show you the footage and give you a photo report. For old brownstones in neighborhoods like Brooklyn Heights and Morningside Heights, that camera view often reveals issues that a visual-only check would miss.
Three things move the price most: flue height, creosote condition, and roof access. A four-story walk-up in the Upper West Side takes longer to set up than a two-story rowhouse in Greenpoint. Heavy glazed creosote takes more work than light soot. Roof pitch and access matter too, especially on Manhattan brownstones with steep roofs or tight courtyards. We factor all of that into a written price before we start, so you know the number up front. Estimates are free.
We price by the job, not the hour. You get one written number that covers the sweep, the inspection, the report, and the cleanup. If we find repair work while we're in there, that's a separate written quote and we won't touch it until you approve it. The Kingswell Guarantee means the price we give you before the work is the price you pay, period. Call (315) 644-2982 and we'll give you a range over the phone.
For most New York homes with a working fireplace, yes. The standard rule from the National Fire Protection Association is to have your chimney swept at least once a year, and in New York the stakes are real: older flues, shared party walls in neighborhoods like Murray Hill and East Harlem, and long heating seasons. A sweep costs less than a restaurant dinner for four and takes about an hour. The alternative is creosote buildup that becomes a chimney fire risk or a hidden flue crack that turns into a carbon monoxide problem. It's cheap insurance.
Service & Process FAQs
A standard single-flue sweep takes 45 to 90 minutes once we're set up. The total appointment, including roof work, camera inspection, and the walkthrough of what we found, usually runs about two hours. If you have a multi-flue chimney or heavy creosote, it can run longer. We give you a real arrival window when you book and we show up in that window. That's a Kingswell Way commitment, and it's in writing.
Not much. Move anything fragile off the mantel, keep pets out of the room, and make sure there's clear floor space around the fireplace. We bring our own drop cloths, vacuums, and equipment. If your firebox hasn't been used in years, that's fine; don't try to clean it yourself first. We've swept plenty of chimneys in New York that hadn't been touched since the Nixon administration. The mess stays contained.
Yes, though gas chimneys usually need sweeping less often than wood-burning ones. Gas produces less creosote, but it can still produce soot, debris, or blockages from bird nests and mortar fall. In New York, we regularly find gas fireplace flues blocked by pigeon nests, especially in Manhattan neighborhoods where pigeons are a constant. The camera inspection will show you exactly what's in there. We sweep gas, wood, and pellet flues.
A sweep is the cleaning; an inspection is the assessment. We usually do them together. During a sweep, we remove creosote and soot so the flue is safe to use. During the inspection, we look at the structural condition of the flue liner, the masonry, the damper, and the cap. Think of the sweep as changing the oil and the inspection as the whole-car check. Our camera inspection is included with every sweep, so you get both in one visit.
Once a year if you use your fireplace at all during the heating season. The National Fire Protection Association recommends annual inspection and cleaning as needed. New York's winters are long enough that most homeowners burn dozens of fires between November and March, and every fire adds a layer of creosote to the flue. If you burn green or unseasoned wood, you'll need sweeping more often. If you just bought an older home in Brooklyn or Manhattan, get it swept before your first fire.
We usually work from both directions. We start from inside to protect the room and keep the debris contained, then finish from the roof to make sure the cap and crown are clean and the top of the flue is clear. On some New York rowhouses, especially the steep-fronted brownstones in Brooklyn Heights, roof access is tight and we adapt. Either way, the result is the same: a clean flue and a camera report showing it's clean.
The short answer: creosote accumulates, and creosote is fuel. A thick layer of creosote inside the flue can ignite from a hot ember and start a chimney fire, which can spread into the house through cracked masonry. You can also end up with blocked flues from bird nests or fallen mortar, which push smoke and carbon monoxide back into the living space. The camera footage from years-skipped chimneys in Red Hook and East New York tells the story plainly. We'd rather sweep it now than fix the damage later.
Brands & Parts FAQs
We install parts from established manufacturers like Olympia Chimney, Copperfield, and DuraFlex. These are the same brands used by professional sweeps across the country because the parts hold up and are covered by real warranties. If you need a new cap, a damper, or a stainless liner, we'll quote you the brand we recommend and explain why it's the right fit for your chimney. You'll see the brand name on the written estimate before you approve anything.
When the old clay tile liner is cracked or spalled, yes. Stainless steel liners from brands like DuraFlex are the standard fix for older New York chimneys that can't be safely used with the original clay liner. The liner is sized to your flue and carries a written warranty. We won't tell you to replace a liner unless the camera footage shows it's needed. If the old liner is sound, we'll say so plainly and recommend a sweep instead. That's the whole idea: show you the flue, then tell you the truth.
Yes. A stuck or warped damper is one of the most common problems we see in New York fireplaces, especially in older buildings where the damper hasn't been touched in decades. We install top-mount dampers and traditional throat dampers, and we use brands like Famco and Olympia Chimney when the job calls for it. A working damper matters more than most people think: it keeps drafts out when the fireplace isn't in use and keeps heat from escaping up the flue all winter long.
For New York, you want a stainless steel cap with a spark arrestor and a screen fine enough to keep birds out. Pigeons and starlings are a constant issue in neighborhoods from Maspeth to Midtown Manhattan, and a nest inside the flue is both a blockage and a fire hazard. We install caps from Olympia Chimney and Copperfield, sized to your flue, and we check the cap during every sweep. A good cap lasts years and pays for itself the first time it stops a nest.

Emergency & Response FAQs
If you've had a chimney fire or you suspect carbon monoxide is coming from your flue, stop using the fireplace immediately and call (315) 644-2982 during business hours. Our hours are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM; we're closed Saturdays. We'll assess the situation over the phone and get you scheduled as quickly as we can. If you have smoke actively pouring into your home, treat it as a fire emergency and call 911 first.
A loud popping or cracking sound from the chimney, dense smoke pouring out of the cap, or a roaring sound like a freight train. After a chimney fire, you might see creosote flakes on the roof or in the firebox, warped metal parts, or cracked flue tiles on the camera. Many New York homeowners miss the signs because chimney fires sometimes burn quietly. If anything felt hot, sounded wrong, or smelled like a campfire long after the fire was out, get it inspected before you burn again.
Yes, and if you're buying an older home in New York, you should. A level-two camera inspection will show the condition of the flue liner, the smoke chamber, and the masonry, and we'll give you a written report with photos you can use in negotiations. In neighborhoods like Upper West Side and Murray Hill, pre-purchase chimney inspections frequently find issues that the general home inspector flagged as "recommend further evaluation." We'll show you exactly what needs fixing and what can wait. Call (315) 644-2982 to schedule.
Warranty & Guarantees FAQs
It's four promises, put in writing: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on the work. If a repair fails inside the guarantee period, we come back and fix it at no charge. Nathan Corliss and the New York team work to that standard on every job, no exceptions. It's not marketing language; it's the same guarantee that's stamped on every Ashby Chimney service across the country.
The specific term depends on the repair. Chimney caps, liners, dampers, and masonry work each carry their own written warranty period, and we'll put the exact terms on your estimate before you approve the work. The Kingswell Guarantee covers the workmanship on top of any manufacturer warranty on the parts. If something fails inside the guarantee period, the fix is on us. No pro-rating, no fine print games.
Call us. We'll come back and make it right. That's the guarantee in plain language, and it's why we show you the camera footage before we pack up: you can see the flue is clean with your own eyes. The Kingswell Way says leave the place cleaner than we found it and come back if it fails. We stand behind that in New York, from East New York to Manhattan. You shouldn't have to wonder if the job was done right when you can see it for yourself.
Call (315) 644-2982 and we'll give you a price range over the phone based on your fireplace type, flue height, and what you're seeing. The written estimate you'll get before any work starts is exact, not an estimate. Estimates are free, and there's no obligation. If you're in Manhattan, Brooklyn, Queens, or anywhere else in the five boroughs, we'll get you on the schedule at a time that works.
