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.

AfterHow Much Does Chimney Cleaning & Sweep Cost in Cambridge?
Chimney Cleaning & Sweep Near Me in Cambridge, MA typically costs typically costs between $179 and $349 for a standard single-flue fireplace, depending on the level of buildup, the type of appliance, and whether a camera inspection is included. Most Cambridge homeowners who use their fireplace regularly through a New England winter pay somewhere in the middle of that range. A full Level-2 camera inspection with the sweep generally runs $249 to $399 and gives you documented proof of your chimney’s condition – photos you can actually see, not just a technician’s word for it.
Chimney Cleaning & Sweep Cost Breakdown (2026)
The table below reflects what Cambridge homeowners are realistically paying in 2026. These are market ranges based on the Greater Boston area, accounting for local labor costs, the age of Cambridge’s housing stock (a lot of pre-1940 chimneys with original clay tile liners), and the typical amount of work involved in a single-season sweep. Your exact number depends on what the technician finds when they open the firebox – we’ll say more about that below.
| Service | Typical Cambridge Price Range (2026) |
|---|---|
| Standard chimney sweep, single flue (wood fireplace) | $179 – $279 |
| Chimney sweep + Level-1 visual inspection | $199 – $299 |
| Chimney sweep + Level-2 camera inspection | $249 – $399 |
| Gas fireplace cleaning and inspection | $149 – $249 |
| Wood stove or insert cleaning | $199 – $319 |
| Pellet stove cleaning | $179 – $299 |
| Oil furnace flue cleaning (single flue) | $189 – $289 |
| Second flue (added to any sweep) | $99 – $179 additional |
| Heavy creosote buildup (Stage 2 or 3 deposits) | $349 – $599 |
| Chemical creosote treatment (Poultice method) | $299 – $499 |
| Dryer vent cleaning | $109 – $179 |
A few things are worth understanding about how these numbers land in practice. Cambridge has one of the denser concentrations of Victorian and Colonial Revival multi-family homes in Massachusetts – many built between 1880 and 1930 with tall, narrow chimney flues and original clay tile liners. Sweeping a chimney that runs four stories in a triple-decker in the Port neighborhood is simply a different job than sweeping a one-story liner in a newer home. Height, access difficulty, and liner condition all shift the final number.
The other factor that moves the price meaningfully is Creosote Removal stage. Light, first-stage creosote – the dry, flaky kind – sweeps out cleanly in one visit. Second-stage glazed creosote or third-stage tar deposits require specialized chemical treatments and additional labor. At Hearthstone Chimney Co., we document what stage we find with our Level-2 camera inspection before quoting additional work, so you see exactly what we saw. No surprises on the bill.
What Affects Chimney Cleaning & Sweep Pricing in Cambridge
- Chimney height and roof access. Cambridge has a lot of steep-pitched roofs, third-floor flats, and attached row houses in neighborhoods like Mid-Cambridge, Agassiz, and Cambridgeport. When a chimney stack rises above a steeply pitched roof with limited safe footing, technicians need additional time and equipment. That labor is reflected in the price. Any work involving steep roofs or heights should be handled by trained professionals – this isn’t a DIY situation.
- Creosote buildup level. A fireplace used regularly through a Cambridge winter – especially one burning unseasoned or softwood – can accumulate heavy glazed creosote in a single season. Stage-2 and Stage-3 deposits require chemical treatment (we use professional-grade products supplied through Copperfield) and sometimes multiple visits. This is the single biggest variable in final pricing.
- Liner type and condition. Many Cambridge homes still have original clay tile liners. Older liners crack, spall, and sometimes shift at mortar joints. A sweep that uncovers liner damage triggers a separate repair conversation – but we document it with photos and give you a plain-English verdict before anything changes hands.
- Number of flues. Pre-war multi-family buildings in East Cambridge and the Wellington-Harrington neighborhood often have two or three separate flues in one chimney stack – one for each unit’s fireplace or furnace. Each flue is a separate sweep with its own pricing.
- Type of appliance. Wood-burning fireplaces and stoves produce creosote; gas appliances do not, but they still accumulate debris and need burner inspection. Pellet stoves have specific cleaning requirements around the combustion chamber and exhaust components. The appliance type drives both the method and the time required.
- Inspection level included. A Level-1 visual inspection is included in most routine sweep appointments. A Level-2 inspection – required by the NFPA 211 standard any time you’ve had a chimney event like a flue fire, change in appliance, or a home sale – adds camera documentation of the full liner interior. In Cambridge, where many homes change hands and many buyers discover deferred maintenance after closing, Level-2 inspections are more the rule than the exception for chimneys over 40 years old.
Cambridge Chimney Specifics Worth Knowing Before You Book
Cambridge isn’t a generic market, and a pricing guide that ignores the local reality isn’t worth much. Here’s what 42 years of serving Greater Boston has taught us about what makes Cambridge chimneys different from the average.
Pre-1940 Housing Stock
The Harvard Square, Avon Hill, and Strawberry Hill neighborhoods are dense with pre-war homes – many owner-occupied for decades and, in some cases, never having had a professional chimney inspection. When we work in these areas, we regularly find clay tile liners with offset sections, missing mortar at the smoke chamber, and dampers that stopped sealing properly years ago. None of that is unusual. But it does mean that a “simple sweep” sometimes turns into a documented repair estimate before we leave. We’d rather find it now than after a flue fire.
The Cambridge Winter Burn Season
Cambridge averages around 93 heating degree days in January alone – cold enough that a wood-burning fireplace or stove sees real use from October through March. That’s five to six months of burn time, and at the recommended standard of one cord of hardwood per season, a well-used fireplace can accumulate significant creosote by spring. NFPA 211 recommends annual sweeping for any fireplace in active use – and in a Cambridge winter, “active use” isn’t an exaggeration.
Permit and Code Context
Cambridge follows Massachusetts State Building Code Chapter 10 for solid-fuel appliances and chimney construction, which incorporates NFPA 211 standards. If you’re relining a chimney – something that comes up often in older Cambridge homes where the original liner is deteriorated – the work requires a building permit from the City of Cambridge Inspectional Services Department. Hearthstone handles that process as part of a liner installation job. A sweep alone doesn’t trigger a permit requirement, but any structural repair or liner replacement does.
Multi-Unit Buildings
A significant portion of Cambridge housing is multi-family – two-family owner-occupied houses, three-deckers, and small apartment buildings. If you own one of these, each unit’s appliance and flue should be swept and inspected individually. We work with landlords and property managers throughout Cambridge, including in the dense residential corridors along Massachusetts Avenue and in the Riverside neighborhood, and we’re accustomed to coordinating access across multiple units in a single visit.
How to Save on Chimney Cleaning & Sweep
There’s honest money to be saved on Chimney Cleaning & Sweep services, and there’s false economy that costs more in the end. Here’s the practical version.
Schedule in the Off-Season
Late spring and summer – roughly May through August – are slower for chimney sweeps across Greater Boston. Some companies offer reduced pricing in those months, and availability is wider, which means you’re more likely to get a time slot that actually works for you. The chimney doesn’t care when it gets cleaned; the soot from last winter’s fires will wait. Booking in June rather than October can shave $30 to $50 off your appointment at some companies, and you avoid the fall rush entirely.
Combine Services in One Visit
If you have a fireplace and a dryer vent that needs cleaning, or two flues in the same chimney stack, getting both done in a single visit is almost always cheaper than two separate appointments. The technician is already there, the truck is already parked. Ask when you book.
Use Hearthstone’s Standing Offers
Hearthstone Chimney Co. offers a permanent 5% discount for seniors and veterans – no expiration, no code needed, just mention it when you call. We also offer $50 off any repair over $250 and a Free Second Opinion on any written estimate you’ve received from another company. If you’re not sure whether a competitor’s repair quote is fair, bring it to us. We’ll look at the same chimney and give you our honest read.
Don’t Skip the Inspection to Save Money
A sweep without an inspection is a sweep in the dark. The point of annual chimney cleaning isn’t just removing creosote – it’s catching liner cracks, damaged caps, deteriorated crowns, and separated flue tiles before they become expensive structural problems or, worse, fire hazards. Skipping the inspection to save $40 on today’s bill is how you end up with a $2,000 liner repair that could have been caught and addressed earlier.
Get a Free Estimate
You don’t have to guess what your Cambridge chimney will cost to clean. Call (857) 392-4709 and a live person will answer – not a voicemail, not a callback queue. We’ll talk through your setup, give you a realistic range, and schedule a no-obligation appointment. The number on the estimate is the number on the invoice.
Is It Worth Getting a Level-2 Camera Inspection?
For most Cambridge homeowners, yes – and here’s why. A Level-2 camera inspection runs your total cost up by roughly $70 to $120 compared to a sweep with a basic Level-1 visual check. What you get in return is a documented record of your flue’s interior condition: actual photos of the liner, smoke chamber, and firebox that you can keep and refer to if questions come up with an insurance company, a home buyer, or a contractor years from now.
In a city where many chimneys are 80 to 100 years old, that documentation isn’t a luxury. It’s the difference between knowing your chimney is safe and hoping it is. Our Chimney Cleaning & Sweep in Cambridge service includes Level-2 camera documentation as a standard option, and every inspection ends with photos the homeowner can see and a plain-English verdict – no technical jargon, no vague reassurances.
NFPA 211 also specifically requires a Level-2 inspection when a home changes ownership, when an appliance type is changed, or after any event that may have caused damage to the flue (including a chimney fire, even a small one you weren’t sure about). If any of those apply to your home, a Level-2 isn’t optional – it’s the correct standard of care.
Repair vs. Replacement: When Cleaning Finds a Problem
Sometimes a routine sweep uncovers something that needs more than cleaning. In Cambridge, the most common findings are:
- Cracked clay tile liner sections – especially in the straight runs of tall chimneys where thermal cycling has stressed the tile joints over decades.
- Deteriorated mortar at the smoke chamber – common in homes where the fireplace was heavily used through many winters and the original mortar has softened or cracked.
- Missing or damaged chimney caps – Cambridge gets meaningful rainfall and freeze-thaw cycling every winter; a missing cap accelerates interior deterioration quickly.
- Spalling brick at the crown – the flat masonry surface at the top of the chimney stack takes direct weather exposure and is often the first thing to show age.
When we find repair-level work during a sweep, we document it with photos, explain what we found in plain English, and give you a written estimate before anything changes. You decide what to do next. There’s no pressure, no bait-and-switch, no vague “you need a lot of work done” without showing you exactly what we mean. That’s the way Russell Haines built this company, and it’s still how we operate after 42 years.
For repair pricing, our $50 Off Any Repair Over $250 offer applies automatically – mention it when you call, or it’ll be on your estimate.
What You Can Expect on the Day of Your Sweep
Our technicians arrive in uniform, on time, and with their names on file as background-checked. They put down drop cloths before opening the firebox, use commercial-grade rotary brush equipment and a HEPA-filtered vacuum system to contain ash and soot, and document the inspection with camera equipment that shows you real-time footage of your liner if you want to watch.
Most single-flue sweeps in Cambridge take between 45 minutes and an hour and a half, depending on the chimney’s height, condition, and access. A two-flue job or a chimney with significant buildup takes longer – we’ll give you a realistic time estimate when we book. Most jobs are completed in a single visit.
When the work is done, you get a written record of what was swept, what was found, and what – if anything – needs attention. That documentation is part of what the 90-Day Done Right Promise covers: if something wasn’t right, we come back and make it right, in writing, no arguing.
FAQs – Chimney Cleaning & Sweep Cost in Cambridge
How much does chimney cleaning cost in Cambridge, MA in 2026?
A standard single-flue chimney sweep in Cambridge costs between $179 and $279 for a wood-burning fireplace in typical condition. Add a Level-2 camera inspection and the range moves to $249 to $399. Heavy creosote buildup (Stage-2 or Stage-3 deposits) pushes pricing to $349 to $599 and may require a follow-up chemical treatment. Call (857) 392-4709 for a free estimate on your specific setup.
How often should a chimney be cleaned in Cambridge?
Annual cleaning is the NFPA 211 standard for any fireplace or wood stove in regular use. Given Cambridge’s five- to six-month heating season and the heavy-use pattern that comes with it, once a year is the right frequency for most households. A fireplace used only a few times a season can reasonably go every two years, but an annual inspection – even if cleaning isn’t needed – catches developing problems before they become costly ones.
Can you clean a chimney the same day I call?
During off-peak months (roughly May through August), same-day or next-day scheduling is often possible. During the fall sweep season – September through November – Cambridge demand is high and appointments typically book one to two weeks out. Calling early in the season is the simplest way to get the date you want. Our phones are answered by a live person every day of the week, any hour – call (857) 392-4709 and we’ll tell you exactly what’s available.
Is it cheaper to skip the inspection and just get a sweep?
You can skip the camera inspection and pay less upfront, but a sweep without any inspection misses the reason annual cleaning matters: catching liner damage, cap failures, and deteriorated mortar before they become fire hazards or expensive structural repairs. A basic Level-1 visual inspection adds very little to the cost of a sweep and should be included in any professional appointment. Skipping it entirely is a false economy, particularly in Cambridge’s older housing stock where liner problems are common.
Do you offer a guarantee on your chimney cleaning work?
Yes. Every job Hearthstone Chimney Co. completes is covered by our 90-Day Done Right Promise: if the work isn’t right, we come back and make it right. That’s in writing, with no paperwork to fill out and no arguing. It’s not a marketing line – it’s the way Russell Haines has run this company since 1984, and it applies to every sweep, inspection, and repair we do in Cambridge.
What’s the difference between a chimney sweep and a chimney inspection?
A Fireplace Cleaning removes combustion deposits – creosote, soot, ash, and debris – from the flue and firebox. A chimney inspection assesses the structural and functional condition of the chimney system. The two are often done together, but they’re distinct services. A sweep without any inspection cleans the chimney; an inspection without a sweep tells you the condition but doesn’t address buildup. For most Cambridge homeowners, a combined sweep-and-inspection appointment is the right call, both for safety and for getting accurate documentation of the chimney’s condition.

"Swept it, capped it, and fitted a proper damper. The downdraft smell we had lived with every summer is gone."
- Allison Doyle"The cap keeps the birds out now, which after two springs of scratching noises above the bedroom is worth every penny."
- Nisha Gupta"Creosote buildup was worse than I realized. He measured it, put a camera up to show me the glazing on the flue, and was honest that we were closer to a chimney fire than I wanted to hear."
