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.

AfterTrusted Chimney Cleaning & Sweep for Boston Homeowners
A chimney cleaning and sweep in Boston typically costs between $189 and $349, depending on the size of the flue, how much creosote has built up, and whether you need a Level 1 or Level 2 inspection alongside it. Most homes in neighborhoods like Dorchester, Jamaica Plain, and West Roxbury need a sweep every one to two years, more often if you burn wood daily through a New England winter. Level Two Chimney Boston has completed more than 38,000 inspections and cleanings since 2009, and every single one included a written price before work started and a documented photo record when it was done. That’s the Haven Standard, and it’s how we’ve worked from the beginning. If your fireplace smells musty, your smoke backs up into the room, or you simply can’t remember the last time anyone looked at the flue, call (857) 567-8887 and we’ll get you on the schedule.
Key Takeaways:
- A standard chimney sweep in Boston runs $189 to $349, with written pricing before any work begins.

- The 365-Day Done Right Promise backs every sweep: if it’s not done right, we make it right.
What Our Chimney Cleaning & Sweep Service Includes
Every chimney cleaning and sweep in Boston starts with a camera-scan inspection before a brush ever touches the flue. We follow NFPA 211 Level 2 protocol on every job, which means the camera goes down the flue and into the smoke chamber, not just a flashlight glance from the roof. Here’s what each part of the service covers.
Level 1 Inspection
A Level 1 Inspection is the standard check for chimneys that haven’t changed since the last sweep, with no new appliance, no fuel switch, and no weather event like a lightning strike or chimney fire. Our technician examines the readily accessible portions of the flue, the firebox, the damper, and the exterior masonry, then runs the camera to document what the eye alone can’t reach. If you use the fireplace the same way you always have and nothing has shifted, this is what you need. We write up what we saw and hand you the photo record before we leave.
Level 2 Inspection
A Level 2 inspection is required when you’re buying or selling a home, after a chimney fire or seismic event, or when you’ve changed the appliance or fuel type. It includes everything in Level 1 plus a full camera scan of the interior flue, the smoke chamber, and the crown from the roof side. In Boston, where half the housing stock is brick or stone over a hundred years old, a Level 2 inspection often surfaces spalling brick, cracked flue tiles, or a rusted-out damper that a standard sweep would miss. We’ve been running camera-scan documentation as standard practice since 2009, years before regulators or insurers began asking for it, and that documentation now forms Clause 4 of the Haven Standard.
Creosote Removal
Creosote is the tar-like residue that condenses from wood smoke and coats the inside of your flue. It forms in three stages: Class I is a light, flaky soot that brushes off easily; Class II is a crunchy, granular buildup; Class III is a hardened, glazed tar that’s fuel for a chimney fire. Level Two Chimney Boston uses a combination of mechanical brushing and, when needed, Creosote Removal with chemical treatment to break down Class II and Class III buildup safely. We tell you the class we found and what it means for your burn habits, in plain language, before we recommend any follow-up work.
Soot Removal
Soot is the soft, powdery carbon that clings to the flue walls, especially in oil-fired and gas systems. While it’s less flammable than glazed creosote, soot buildup restricts draft, pushes carbon monoxide back into the living space, and accelerates liner corrosion. Our sweep removes soot thoroughly and documents the before and after with the camera so you can see the difference. If your oil furnace vents through the chimney, this is a non-negotiable annual service.
Annual Sweep
An annual sweep is the baseline service for any home that burns fires regularly during the Boston heating season, which runs from October through April in a typical year. We clean the full flue, the smoke chamber, the damper assembly, and the firebox, then run the camera to verify nothing was missed. The National Fire Protection Association recommends a sweep when creosote reaches 1/8 inch thick, but most Boston homeowners simply book once a year before burning season. The whole visit usually takes 45 to 90 minutes, and you leave with a written record of what was swept and what we found.
Fireplace Cleaning
Fireplace Cleaning goes beyond the flue, addressing the firebox, the hearth, the screen, and the glass doors where soot and ash accumulate. We remove old ash, scrub the firebrick, clean the glass with a non-abrasive cleaner, and make sure the damper opens and closes smoothly. This is the part you see every day, and it’s the part most homeowners notice first. A clean firebox also lets the camera inspection do its job properly, since we’re looking at mortar joints and firebrick integrity rather than last winter’s ash.

Brands We Service for Chimney Cleaning & Sweep
We’ve swept and inspected chimneys running HeatShield and Olympia Chimney liners in every Boston neighborhood from Beacon Hill to Hyde Park, and we stock the parts needed to maintain those systems correctly. HeatShield is a ceramic-based lining system we use and service regularly; when the camera shows spalled or cracked clay flue tiles, HeatShield’s resurfacing process is often the least invasive fix. We can assess whether your existing HeatShield application is holding up and document its condition in the photo report you take with you.
Olympia Chimney supplies stainless steel liners and caps we see frequently in Boston, particularly in homes where the original clay tile liner was replaced in the last decade. We source replacement components through Haven’s buying network, which includes Gelco and Famco, specifically to keep customer prices honest. Whether your system runs HeatShield, Olympia, or any other make, the camera doesn’t care about the brand, it just shows us the condition, and we adjust the sweep and maintenance accordingly.
BeforeAfterSigns You Need Chimney Cleaning & Sweep Right Now
- Smoke backing up into the room instead of drawing up the flue. This usually means the flue is partially blocked by creosote, a bird nest, or a collapsed flue tile. Draft failure pushes carbon monoxide into the living space, and that’s not a cosmetic problem.
- A sharp, campfire-like smell that gets stronger on humid days. Creosote absorbs moisture from Boston’s humid summers and off-gasses that acrid smell. If you notice it when the air conditioning runs, the creosote has built up enough to matter.
- Black, flaky or shiny tar deposits visible on the damper or firebox walls. Shiny, glazed creosote is Class III and it’s fuel for a chimney fire. We can tell you the class by looking, but the camera tells us the full extent.
- You haven’t had the chimney swept in over two years, or you just bought the house and have no record. Boston homebuyers frequently inherit chimneys that haven’t been looked at in a decade. A Level 2 inspection is the right first move when there’s no service history.
- A fire that’s hard to start, hard to keep going, or produces less heat than it used to. Poor draft often traces back to creosote narrowing the flue. A clean flue draws air properly, burns more efficiently, and saves you wood.
Our Chimney Cleaning & Sweep Process - Step by Step
- 1
You call, we pick up. A live person answers at (857) 567-8887, 24/7. We’ll ask about your fireplace or stove, how often you use it, and the last time it was swept. Then we give you a written price for the sweep and any inspection before the technician ever schedules the visit. Never a ballpark that changes later.
- 2
Your named technician arrives with the written scope in hand. You’ll get a text when they’re on the way, and the tech shows up in uniform with a background check already on file. Before any work starts, the written scope, written price, and written warranty are in your hands, not the other way around.
- 3
Protection goes down first. We lay drop cloths from the entry to the fireplace, seal the opening with a HEPA filtration setup to keep dust out of the room, and protect the hearth. The flue gets swept from the roof or through the firebox, depending on your chimney’s access.
- 4
The camera goes down the flue. This is the NFPA 211 Level 2 standard we’ve run on every job since 2009. We document creosote class, liner condition, smoke chamber integrity, and crown status. You see what we see, on the screen or after, in the photo record.
- 5
You get the write-up, the photos, and the honest answer. If the flue is clean and the liner is sound, we say so. If there’s spalling, a cracked flue tile, or a crown that needs repointing, we show you the photo and give you a written price for the fix. Nothing is recommended without camera evidence you can see. If it can safely wait, we tell you that too.
How Much Does Chimney Cleaning & Sweep Cost in Boston?
A standard chimney cleaning and sweep in Boston runs $189 to $349 for a single flue, with the higher end typically involving a two-story chimney, a steep roof in neighborhoods like Brighton or Mission Hill, or heavy Class II creosote that takes extra time. Adding a Level 2 inspection to the sweep adds about $75 to $150 depending on access and flue length. Here’s the line-item breakdown by scenario:
- Standard sweep with Level 1 inspection: $189-$279
- Sweep with Level 2 camera inspection: $264-$429
- Creosote removal (Class II or III, chemical treatment added): +$50-$120
- Fireplace cleaning (firebox, glass, hearth): +$40-$90
- Roof access on steep pitches or three-story Boston rows: +$35-$75
What affects the price most is the honesty of the company doing the work. Some Boston sweeps quote low, then “discover” a liner problem once they’re in your living room. We don’t do that. Haven Standard Clause 1 requires a written price, written scope, and written warranty before anyone starts, and Clause 4 requires the camera documentation that proves what we found. You never pay for a repair recommendation you can’t see in the photo record. To avoid overpaying, get the price in writing before the tech arrives, and ask to see the camera footage for any recommended repair. A free estimate from Level Two Chimney Boston includes the inspection itself, the written price for the sweep, and a straight answer about what can wait.

Frequently Asked Questions - Chimney Cleaning & Sweep in Boston
Chimney cleaning and sweep is the removal of creosote, soot, and debris from the inside of your flue, smoke chamber, and firebox. It’s the only way to prevent chimney fires, which occur when creosote ignites and burns at temperatures that can crack flue liners and spread to the house. A proper sweep in Boston also includes a camera inspection of the flue and a written record of what was found. That’s the standard we’ve worked to since 2009.
A standard chimney sweep takes 45 to 90 minutes from setup to photo record. If you’ve added a Level 2 inspection, fireplace cleaning, or there’s heavy Class III creosote that needs chemical treatment, the visit runs closer to two hours. We’ll tell you the expected duration when you book, based on what we know about your system. Call (857) 567-8887 and we’ll give you a time window and a written price up front.
A chimney cleaning in Boston costs $189 to $349 for a standard single-flue sweep. The variables are roof access, flue length, creosote class, and whether you add a Level 2 camera inspection or fireplace cleaning. Every job at Level Two Chimney Boston includes a written price before we start, so you know the exact number before the technician arrives. For a free estimate, call (857) 567-8887.
Only a camera scan can tell you definitively. If the flue tiles are cracked, spalled, or missing, the liner is compromised and the sweep alone won’t make the chimney safe. If the liner is intact and the creosote is manageable, you don’t need a new liner, plain and simple. We never recommend a liner or any other repair without showing you the camera evidence, per Haven Standard Clause 4. If it can safely wait, we write that down too.
Burn wood regularly through a Boston winter? Sweep once a year, before burning season kicks in around October. Burn occasionally or run a gas insert? Every two years is typically adequate. The National Fire Protection Association says sweep when creosote reaches 1/8 inch thick, but the practical answer for most Boston homeowners is a yearly sweep as part of pre-season prep. Call (857) 567-8887 and we’ll help you set a cadence that matches how you burn.
Creosote builds up, the flue narrows, and the chimney can’t remove smoke and carbon monoxide efficiently. Glazed Class III creosote becomes fuel for a chimney fire, which burns hot enough to crack the flue liner and spread into the house framing. Even without a fire, a blocked flue pushes CO back into the living space, and that’s odorless, invisible, and potentially fatal. A $189 sweep is the cheapest insurance you’ll buy this year.
We do, and we see more pre-1900 brick chimneys in Boston than anywhere else in New England. Historic chimneys have their own failure patterns: lime mortar, unlined flues, shallow fireboxes, and deteriorated crowns. The camera scan tells us exactly what condition yours is in, and we write the repair recommendation, if any, in plain language with photos to back it up. Whether it’s a South End brownstone or a triple-decker in Dorchester, we’ve swept it.
We answer calls live, 24/7, at (857) 567-8887, and we’ll get a technician out for urgent situations like water coming through the chimney, a chimney fire, or a strong carbon monoxide alarm event. If the situation is life-threatening, call 911 first, then call us. For non-emergency sweeps, we’ll schedule you for the soonest available window and put the price in writing before we arrive. No answering service, no voicemail, no web form.
Every job at Level Two Chimney Boston is backed by the 365-Day Done Right Promise, stamped on every job under the Haven Standard. If the sweep or inspection isn’t done right, we make it right, no argument and no charge. You also leave with a written warranty covering the work performed, not a verbal assurance. That’s how we’ve handled all 38,000+ cleanings since 2009.
Keep the area around the fireplace clear of furniture, decor, and anything delicate, and stop using the fireplace at least 24 hours before the appointment so everything is cold. If there are ashes in the firebox, leave them; we’ll remove them as part of the fireplace cleaning. Move any vehicles out of the driveway if the chimney is accessed from the roof, since we may need ladder placement. We’ll text you when we’re on the way, with the name of the technician assigned to your job.
