Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Trusted Chimney Sweep for Yonkers Homeowners
A chimney sweep in Yonkers usually costs between $180 and $340 for a standard cleaning and inspection, and you should expect the entire visit to take 45 to 90 minutes. That’s the straightforward answer most homeowners are looking for. Hadley Chimney Yonkers has been doing this work since 2003, so we’ve swept thousands of flues across Westchester and the Bronx, and we know exactly what Yonkers homes throw at us: older masonry, steep rooflines near the Hudson, and creosote (the flammable tar buildup that makes chimneys a fire risk) that accumulates fast when you burn wood through a Northeast winter. For a full breakdown of what to watch for, see our Chimney Sweep Maintenance Checklist for Yonkers Homeowners. If your fireplace has made it through even one season since its last cleaning, call us today at (914) 233-3156 and we’ll get you on the schedule with a written price before any brush touches your flue.
Cory Mitchell leads our Chimney Sweep in Yonkers crew, and he’s built the whole operation around one idea: you should see exactly what we see. That means photos of your flue before and after, a live arrival window you can track from your phone, and a written quote handed to you before work begins. No vague verbal estimates. No “we’ll see when we get up there” pricing. Just a chimney company that treats your time and money like they’re ours.
Chimney Sweep Services
Chimney Sweep Services cover the mechanical removal of creosote, soot, and debris from your flue liner and smoke chamber, plus a visual inspection of the entire chimney system. Most Yonkers homes need this once a year if you burn wood regularly, or every other year if your fireplace only gets lit on holidays. A standard sweep and inspection from Hadley Chimney Yonkers runs $180 to $340, and that price is written down before we start, not discovered after. We also handle animal nest removal, smoke shelf cleaning, and full camera inspections when a visual check isn’t enough.
Sweep and Level 1 Inspection
This is our bread and butter for the homeowner who burns regularly and wants peace of mind without overpaying. We remove creosote throughout the flue, clean the smoke shelf and damper area, then inspect the firebox, cap, and crown for obvious damage. Most of these visits wrap up in under an hour, and you’ll have a photo report in your inbox before the truck leaves your street.
Heavy Creosote and Glaze Removal
Yonkers sees its share of wet, cold winters, which pushes homeowners to burn more and burn longer. That creates glazed creosote, the hardened third-stage buildup that a basic brush can’t touch without specialized tools and a lot more patience. We charge more for this work because it takes longer, but you’ll know that before we begin, and we’ll show you photos of the glaze so you understand exactly what you’re paying to remove.

Chimney Cleaning
Chimney Cleaning is the physical process of removing creosote, soot, and blockages from the inside of your flue, and it’s the single most effective thing you can do to prevent a chimney fire. If you hear crackling that sounds like a campfire above your firebox, or you notice a thick, tar-like coating on the damper, it’s time. Hadley Chimney Yonkers performs this service as both a standalone job and part of a full sweep, with pricing from $180 for a straightforward single-flue cleaning. Every job includes a before-and-after look inside your flue, because if we can’t show you it’s clean, you shouldn’t believe it’s clean.
Standard Flue Brushing
We run a fitted wire or poly brush down the full length of the flue, sized to your liner’s exact dimensions, not whatever’s already on the truck. That mismatch is how you end up with missed creosote bands and a false sense of security. Once the flue is brushed, we vacuum through the firebox with a HEPA-filtered unit that keeps fine soot out of your living room.
Smoke Chamber and Damper Cleaning
The smoke chamber sits right above the firebox and below the flue, and it’s where creosote likes to hide in Yonkers chimneys built before modern code updates. A thorough cleaning here means removing buildup from the corbeled brick and checking that the damper operates smoothly. Most chimney companies rush past this area; we don’t, because smoke chamber creosote is a leading ignition point in chimney fires.
Fireplace Cleaning
Fireplace Cleaning focuses on the firebox itself: removing ash, hardened soot, and creosote from the brick or refractory panels where your fires actually burn. You’d do this before winter hits, or any time you notice thick black deposits that won’t brush off with a standard fireplace brush. Hadley Chimney Yonkers includes firebox cleaning in our standard sweep at $180 to $340, or as a standalone service if the flue is clean but the firebox has seen better days. You’ll get photos of the cleaned firebox, and we’ll tell you straight if those refractory panels are cracked and need replacement rather than cleaning.
Firebox Ash and Soot Removal
This is the part you could technically do yourself, but most Yonkers homeowners would rather not wrestle a shop vac full of fine ash on a Saturday morning. We remove everything down to the brick or panel surface, then wipe down the surround so your living room doesn’t smell like last February’s fires. It’s quick, it’s clean, and it’s included with every full sweep we perform.
Refractory Panel Inspection
Those gray panels lining your firebox aren’t decorative; they reflect heat back into the room and protect the firebox brick from thermal shock. When they crack, heat reaches places it shouldn’t, and that’s a repair issue, not a cleaning one. During any fireplace cleaning we inspect every panel and flag anything that needs a closer look, with photos so you can see the crack yourself.
Chimney Services
Chimney Services at Hadley Chimney Yonkers go beyond the sweep to cover everything else your chimney needs: crown repair, flashing replacement, liner installation, damper repair, and full camera inspections. Think of the sweep as your annual physical and these services as the treatments when the physical finds something. Prices vary widely by job, but you’ll always get a written number before we start, and every repair carries our 365-Day Done Right Promise with a written guarantee and a free second visit if the repair fails. No exceptions, no fine print.
Crown and Flashing Repair
Your chimney crown is the concrete cap that sheds water away from the flue, and when it cracks, water works its way into the masonry and starts a freeze-thaw cycle that Yonkers winters accelerate. We see this constantly on homes in the Park Hill and Dunwoodie neighborhoods where chimneys are older, and on many of the historic homes near Chimney Sweep in Mount Vernon. Flashing, the metal that seals the chimney to your roofline, is the other common leak point. We fix both with materials built to handle Northeast weather, not a tube of caulk and a handshake.
Camera Inspection and Liner Evaluation
When a visual inspection raises questions, we run a camera from the firebox to the cap and record the whole trip. That footage is yours to keep, and we’ll sit down with you and walk through what it shows. If the liner is cracked or spalled, we’ll tell you honestly whether replacement is urgent or can wait a year, and we’ll quote you options using brands like DuraFlex and HeatShield that chimney pros trust.
Chimney Sweep Certified
Chimney Sweep Certified means the technician who shows up at your Yonkers door has been trained to industry standards, background-checked, and held to protocols that cover safety, tool handling, and inspection methodology. It’s not a marketing buzzword; it’s the difference between someone who brushes your flue and someone who understands flue dynamics, code requirements, and what a failing liner actually looks like. Every Hadley technician arrives uniformed and tracked, and Cory Mitchell personally maintains the training standards for the team. A certified sweep with inspection runs $180 to $340, depending on flue size and condition.
What Certification Means for Your Inspection
A certified sweep knows that a chimney inspection isn’t just looking up the flue and saying “looks fine.” It’s a systematic check: firebox integrity, damper function, smoke chamber buildup, flue liner condition, cap and spark arrestor presence, crown cracks, and exterior masonry. We document every one of those points, and we show you the photos. If we miss something, the 365-Day Done Right Promise covers making it right.
Why Background Checks Are Non-Negotiable
You’re inviting a stranger into your home, often while you’re at work and your family is going about their day. Every Hadley chimney tech passes a background check and wears a uniform with our name on it, so you know who’s coming and you know they’re accountable to us. That might sound basic until you’ve had a no-name subcontractor show up without ID and ask to use your bathroom.
Gas Fireplace Cleaning
Gas Fireplace Cleaning covers the removal of dust, pet hair, and fiberglass particles from gas log sets, plus inspection of the burner, pilot assembly, and venting. Yonkers homeowners sometimes assume gas means no maintenance, but a gas fireplace that hasn’t been cleaned in three years burns inefficiently, can produce soot on the glass, and may push carbon monoxide into the room if the venting is blocked. A gas fireplace cleaning from Hadley runs $130 to $250 depending on the unit, and it includes verification that the pilot and burner are operating correctly. If the unit needs repair beyond cleaning, we’ll quote it and get your written approval before touching a screw.
Log Set and Burner Cleaning
We remove the log set carefully, vacuum the burner ports, and clean the pilot assembly so the flame burns blue and steady, not yellow and lazy. That yellow flame is unburned gas, and it’s a sign the burner needs attention. We’ll also clean the glass with a non-abrasive cleaner that won’t etch the surface, because replacement glass for some of these units costs hundreds.
Vent Inspection for Gas Units
Direct-vent gas fireplaces pull air in and push exhaust out through a coaxial pipe that can clog with debris or, in Yonkers, become a nest site for birds and squirrels. We inspect the termination cap from outside and confirm the vent path is clear. A blocked vent doesn’t just make your fireplace run poorly; it’s a carbon monoxide concern, and it’s one of the most common issues we find during gas fireplace cleaning visits.
Chimney Maintenance
Chimney Maintenance is the year-round practice of keeping your chimney system safe and functional, not just cleaning it once a year and forgetting about it until fall. It covers seasonal prep, waterproofing, cap installation, minor repairs before they become major ones, and knowing when a real problem is developing. Hadley Chimney Yonkers offers maintenance plans for Yonkers homeowners who burn wood regularly, with annual sweep pricing from $180 and priority scheduling for plan members. We also serve nearby communities with the same level of care, including Chimney Sweep in Tuckahoe. The point of maintenance isn’t more visits; it’s fewer expensive surprises.
Waterproofing and Cap Installation
Masonry absorbs water, and water plus a Yonkers freeze-thaw cycle equals spalled brick and expensive repairs. We apply breathable waterproofing to exterior masonry so moisture can’t get in but vapor can escape, and we install stainless caps that keep rain, snow, and raccoons out of the flue. A capped, waterproofed chimney is a chimney that rarely needs unexpected work.
Pre-Season Safety Checks
Every fall, before you light that first fire in November, a quick safety check catches what summer rain and winter freezes did to your chimney. We look for water staining in the firebox, check the damper operation, and run a brush through the flue if needed. It’s a $180 to $340 visit that prevents the $1,200 liner replacement or the fire that ruins the whole season.
Brands We Service
Hadley Chimney Yonkers works with the brands chimney professionals actually install and repair. DuraFlex flexible liner systems are our go-to for relining Yonkers chimneys, because the corrugated stainless handles the thermal expansion your flue goes through every time you burn, and its flexibility means we can get a continuous liner down a chimney that isn’t perfectly straight, which describes most chimneys built before 1990. We also use HeatShield ceramic repair compound for jobs where the flue liner has minor gaps or cracks but doesn’t need full replacement. HeatShield resurfaces the inside of the flue and seals those gaps, which is often a smarter and more affordable move than ripping everything out.
Gelco chimney caps and Olympia Chimney accessories round out our most-used materials, and Famco ducting and chase covers come into play on newer construction and gas unit work. What that means for you: we’re not grabbing the cheapest part from the supply house and hoping it fits. We’re using the same brands a seasoned chimney tech would put on their own house. Whether you have a HeatShield-lined flue or a gas unit that needs Famco parts, we can help.

- Smoke backing up into the room. This means your flue isn’t drawing properly, either because of creosote buildup, a blocked cap, or a damper that’s not fully open. It’s not just annoying; smoke in the living space carries carbon monoxide, and that’s a health issue you shouldn’t wait on.
- A crackling, rumble sound above the firebox. That noise is creosote igniting in the flue, and a chimney fire is actively happening. You should close the damper if possible, get everyone out, call 911, and then call us once the fire department has cleared the scene.
- Black, tar-like glaze on the damper or firebox walls. Third-stage creosote can’t be removed with a drugstore brush, and attempting to burn it off will start the fire we just described. This needs professional chemical or mechanical treatment, and it needs it before your next fire.
- Water staining on the ceiling or walls near the chimney. That’s a flashing or crown leak working its way into your home’s structure. Every rainstorm makes it worse, and Yonkers gets plenty of rain. Water damage plus the freeze-thaw cycle in winter means the repair cost compounds quickly.
- You can’t remember the last time the chimney was cleaned. If you bought the house and the previous owner “definitely had it swept,” you should still get a camera inspection before your first fire. We’ve found everything from bird carcasses to abandoned tools to full squirrel nests in flues that homeowners were about to light.
Our Process, Step by Step
Step 1: Book Your Window
Call (914) 233-3156 and a live person answers, any hour of the day or night. We’ll ask about your fireplace type, when it was last cleaned, and what you’ve noticed. You pick a window that works for you, and you’ll get live arrival tracking once the tech is en route, so there’s no four-hour guessing game.
Step 2: Walkthrough and Written Price
When your uniformed technician arrives, they’ll look at the fireplace, the chimney exterior, and the roof access point. Then they hand you a written price before any work starts. If you don’t like the number, you can say no and there’s no charge for the visit. That’s how it works at Hadley, every time.
Step 3: The Sweep and Inspection
The tech protects your living space with drop cloths and runs a HEPA vacuum throughout the process so soot stays in the chimney, not in your furniture. They brush the full flue, clean the smoke chamber and firebox, and perform a systematic inspection of the liner, cap, crown, flashing, and damper. Photos are taken throughout.
Step 4: Photo Review and Recommendations
Before the tech packs up, you’ll see the before-and-after photos on their tablet, and they’ll walk you through anything they found. No recommendations are made without camera evidence you can see with your own eyes. If there’s a problem that can wait, they’ll say so. If there’s something urgent, you’ll know exactly why.
Step 5: Digital Invoice and Guarantee
You pay from a link on your phone, no paper checks or “the card reader isn’t working.” Your invoice includes the written guarantee on any repair work, and you’re covered by the 365-Day Done Right Promise: if it’s not done right, we make it right, with a free second visit if the repair fails. The whole thing is wrapped up before the truck leaves your street.
How Much Does Chimney Sweep Cost in Yonkers?
A standard chimney sweep in Yonkers runs $180 to $340 for a single flue with a Level 1 inspection included. If you have a two-flue chimney, which is common in the larger colonials in the Crestwood and Lawrence Park areas, you’re looking at $300 to $500 for both. A gas fireplace cleaning is less, usually $130 to $250. Heavy creosote glaze removal can push the price higher because it requires chemical treatments and significantly more labor, and if a camera inspection reveals liner damage, a DuraFlex relining job in Yonkers typically starts around $2,200 and goes up based on flue height and access. We know that’s a wide range, so here’s what affects it: flue size and height, the amount of creosote buildup, whether there are animals or debris in the chimney, and how easy it is to access the roof from your property. To avoid overpaying, get a written quote before work starts and ask for photos of whatever the technician claims needs fixing. That’s standard with us. Your free estimate from Hadley includes the full inspection, the written price, and the photo documentation.

Frequently Asked Questions About Chimney Sweep in Yonkers
A chimney sweep is the professional cleaning of your flue, smoke chamber, and firebox to remove creosote, soot, and debris. The term also refers to the person who does the work, but for our purposes it’s the service: brushing the flue, vacuuming the residue, and inspecting the entire system. In Yonkers, an annual sweep is the standard recommendation for homes that burn wood regularly, and it costs $180 to $340 at Hadley. Call (914) 233-3156 to book yours.
