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 Boulder Homeowners
Chimney cleaning and sweep service in Boulder, CO typically costs between $189 and $349 for a standard NFPA 211 Level 2 inspection with cleaning, depending on creosote buildup and flue accessibility. Most Boulder appointments are completed in 60 to 90 minutes, and we bring a written price before any work starts. Call (970) 598-0453 to book a slot that fits your schedule.
We’ve cleaned and inspected more than 38,000 chimneys since 2009, and every single one left with a written scope, a written price, and a documented photo record under Clause 4 of the Haven Standard. In Boulder specifically, we see the same patterns year after year: the dry Front Range climate and temperature swings between the plains and the foothills accelerate thermal cycling in masonry flues. That cycling opens hairline cracks that collect creosote faster than chimneys in more humid climates. We’ve documented this in neighborhoods from Mapleton Hill to Martin Acres, and it’s why we include camera-scan inspection as standard, not optional.

What Our Chimney Cleaning & Sweep Service Includes
Level 1 Inspection
A Level 1 Inspection is the visual examination of readily accessible portions of your chimney exterior, interior, and connecting appliance. You need this annually if you’ve kept the same fuel type and your system shows no signs of change, which describes most Boulder homes burning seasoned hardwood through a standard fireplace. At Emberly Chimney Cleaners Boulder, we still bring a flashlight and mirror, but we also run a quick camera check of the first several feet of flue - enough to catch the obvious failures that a pure Level 1 often misses.
Level 2 Inspection
A Level 2 inspection is the NFPA 211 standard we built our name on: camera down the full flue length, inspection of attics and crawl spaces where the chimney passes through, and documented photo record of every surface. You need this before any property sale, after any chimney fire or lightning strike, or if you’ve changed appliances or fuel types - common in Boulder as homeowners switch to gas inserts or pellet stoves. We’ve performed this inspection standard since 2009, and Clause 4 of the Haven Standard requires that photo record on every job. The camera doesn’t lie, and neither do the photos we hand you.
Creosote Removal
Creosote is the tar-like or flaky deposit that forms when wood smoke condenses in a cool flue; it ranges from Class I (sooty dust) to Class III (glazed, hardened, and highly combustible). Boulder homes between 2,000 and 6,000 feet see faster creosote accumulation because colder night temperatures keep flue surfaces below the condensation threshold longer. We remove creosote with Creosote Removal techniques including rotary whips, poly brushes sized to your flue liner, and controlled mechanical scraping for Class III buildup - never chemicals that mask the problem. If we find glazed creosote, we tell you exactly what class it is, show you the camera footage, and explain whether a sweep alone is sufficient or if a chemical conditioning cycle is warranted.
Soot Removal
Soot is the fine carbon powder left by incomplete combustion, and while it’s less hazardous than creosote, it restricts draft and can corrode stainless steel flue liners over time. Gas appliances in Boulder’s newer construction - think the condos near 28th Street or the townhomes in Gunbarrel - produce soot that mixes with condensation to form sulfuric acid. We remove soot with HEPA-contained vacuum systems and soft-bristle tools that won’t score liner surfaces. The vacuum runs continuously during the sweep, so your living room doesn’t smell like a fireplace for three days afterward.
Annual Sweep
An Annual Sweep combines inspection, creosote and soot removal, and a written condition report that satisfies most homeowner insurance requirements. In Boulder, burning season runs roughly October through April, and we recommend scheduling in September before the first cold snap backs up our calendar. We’ve cleaned chimneys in every Boulder neighborhood from Chautauqua to Wonderland Hills, and the homes that sweep annually - every year, without exception - have the fewest emergency calls in January. The 365-Day Done Right Promise covers every annual sweep: if it’s not done right, we make it right.
Fireplace Cleaning
Fireplace Cleaning addresses the firebox, smoke chamber, damper assembly, and hearth extension - the parts you see and the parts you don’t. The smoke chamber, the angled area above the damper that funnels smoke into the flue, is where most Boulder homeowners are surprised by buildup; it’s invisible without a mirror or camera, and NFPA 211 requires it be parged smooth if deterioration exceeds one-quarter inch. We clean the firebox with hand tools, inspect the smoke chamber with a light and mirror or camera extension, and check damper operation and seal. If your damper won’t close fully, you’re losing heated air up the flue every night - and we document that with a photo, not a vague warning.

Brands We Service for Chimney Cleaning & Sweep
We’ve serviced hundreds of HeatShield systems in Boulder County since 2009, and we stock their Cerfractory Foam and smoothing agents for smoke chamber parging and flue resurfacing. HeatShield’s cerfractory material handles the thermal shock of Boulder’s rapid temperature swings better than traditional refractory cement, which is why we specify it for crown repairs above 5,000 feet. We also maintain strong supply relationships with DuraFlex for stainless steel liner installations and with Copperfield for caps, dampers, and specialty flashing. Our materials come through Haven’s buying network, which keeps customer prices honest by eliminating the markup layers that most independents absorb from distributors.
Whether you have a HeatShield-lined system, a DuraFlex stainless insert, a Copperfield cap, or any other make - including factory-built units from brands we haven’t named here - we can help. Our technicians carry the most common replacement parts on their trucks, and what we don’t stock arrives within 24 hours through our supplier network. We never recommend a part swap without showing you the failure on camera first.
BeforeAfterSigns You Need Chimney Cleaning & Sweep Right Now
- Smoke backing up into the room. If your fireplace sends smoke into your living space instead of up the flue, you have a draft failure, partial blockage, or creosote buildup narrowing the flue passage. In Boulder homes built before 1980, we often find this combined with a smoke chamber that was never properly parged - a repair, not just a sweep, but the camera shows you exactly what’s happening.
- Strong, acrid odors when the fireplace isn’t in use. That sharp smell in summer is creosote off-gassing as temperatures rise; it means deposits are significant enough to react to seasonal humidity changes. Left alone, those deposits attract moisture that accelerates liner corrosion, especially in Boulder’s freeze-thaw cycles.
- Visible black buildup on the damper or firebox walls. Anything more than a thin film of soot indicates your system is running outside optimal combustion parameters - too much moisture in the wood, too little air supply, or a flue that’s oversized for the appliance. We measure, photograph, and explain what the buildup pattern tells us about your burning habits.
- It’s been more than 12 months since your last professional sweep. The National Fire Protection Association recommends annual inspection and cleaning as needed; insurance policies increasingly require documentation of compliance. We date-stamp every photo record, and that documentation has helped Boulder homeowners through claims and property sales.
- You just bought the home or changed your heating appliance. A Level 2 inspection is mandatory per NFPA 211 before property transfer or appliance changeout. We’ve found everything from unlined brick flues in North Boulder Victorians to cracked factory-built chimneys in 1990s Gunbarrel subdivisions - problems the previous owner may never have known existed.
Our Chimney Cleaning & Sweep Process - Step by Step
- 1
Schedule and confirm. Call (970) 598-0453 or speak with our live answering service. We confirm your address, appliance type, and any symptoms you’ve noticed. You’ll receive a text with your technician’s name and photo before arrival day.
- 2
Arrival and protection. Your technician arrives in a marked vehicle, wearing a Emberly Chimney Cleaners Boulder uniform. They lay drop cloths from the entry to the fireplace and set up HEPA-contained vacuum equipment. The license number you saw on our website matches the documentation they carry.
- 3
Camera-scan inspection. Before touching a brush, we run a high-resolution camera the full length of your flue. You watch the live feed on a tablet if you’re present, or we record it for later review. This is Clause 4 of the Haven Standard, and we’ve done it on every job since 2009 - no exceptions, no upsell.
- 4
Written price and scope. Based on what the camera found, we deliver a written price, written scope of work, and written warranty before any cleaning begins. Haven Standard Clause 1 requires this: H.A.V.E.N. stands for “Have it in writing.” If you don’t want to proceed, you pay nothing for the inspection.
- 5
Cleaning, documentation, and walkthrough. We complete the agreed work, run the camera again to verify results, and compile your photo record. The technician reviews every image with you, explains what was found and what was done, and leaves you with printed documentation. The 365-Day Done Right Promise applies automatically.
How Much Does Chimney Cleaning & Sweep Cost in Boulder?
A standard chimney sweep with Level 2 camera inspection in Boulder runs $189 to $349. The lower end covers a single-flue system with Class I or light Class II creosote, accessible from the hearth without roof work. The upper end applies to systems with heavy Class III glazed creosote requiring mechanical conditioning, multi-flue chimneys, or setups where we need to access the crown from the roof to complete the inspection.
Here’s how typical scenarios break down in the Boulder market:
- Annual sweep with Level 2 inspection, single flue, standard access: $189-$249
- Heavy creosote removal requiring rotary mechanical treatment: $279-$349
- Fireplace cleaning with smoke chamber inspection and damper service: $159-$219 (when bundled with flue sweep)
- Multi-flue chimney (common in larger Mapleton Hill or Newlands homes): add $89-$129 per additional flue
Several factors move the price. Roof pitch and height affect access time; Boulder’s historic districts have steep pitches and limited parking that add setup complexity. Creosote class determines tool selection and time on site - Class III glazed buildup can take three times longer than Class I soot. Factory-built metal chimneys clean faster than unlined masonry but may require specialized brushes we carry as standard.
To avoid overpaying, get any competitor’s written estimate in hand and bring it to us. Our Free Second Opinion policy means we’ll review their scope and pricing against what our camera finds, with no obligation to book. What’s included in our free estimate: the full camera-scan inspection, a written price valid for 30 days, and your photo record whether or not you hire us. We don’t believe in “call for a quote” because we don’t believe in surprise charges after the tech is already in your home.

Frequently Asked Questions - Chimney Cleaning & Sweep in Boulder
Chimney cleaning and sweep is the physical removal of creosote, soot, and obstructions from your flue and firebox, while an inspection is the systematic evaluation of the system’s condition. At Emberly Chimney Cleaners Boulder, we don’t separate them meaningfully - every sweep includes at least a Level 2 camera inspection because you can’t judge what you’ve cleaned without seeing it first. The Haven Standard requires both the cleaning and the documentation on every visit.
A standard chimney cleaning and sweep in Boulder takes 60 to 90 minutes from arrival to departure, including the camera inspection and walkthrough. Heavy creosote buildup, multi-flue systems, or accessibility complications can extend this to two hours. We schedule appointments with enough buffer that your technician isn’t rushing to the next call - and we text you if any delay affects your start time.
Chimney cleaning and sweep in Boulder costs between $189 and $349 for most single-flue residential systems, with the exact price depending on creosote class, flue accessibility, and whether additional services like smoke chamber parging or damper repair are needed.

Clear a path from your entry to the fireplace, remove fragile items from the mantel and hearth area, and avoid burning a fire for 24 hours before our arrival so the system is cool enough to work in. You don’t need to move furniture or cover anything - we bring drop cloths and HEPA containment. If you have questions about appliance operation, fuel types, or past repairs, gather that information; it helps us tailor the inspection to your system’s history.
