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 Denver Homeowners
A professional chimney cleaning and sweep in Denver typically costs $189-$349 for a standard single-flue system and includes a Level 1 or Level 2 inspection with a documented photo record. Level Two Chimney Denver has completed more than 38,000 chimney inspections and cleanings since 2009, every one with a written price before work started and a camera-scan archive on completion. We’re independently owned and operated under the Haven Standard, and our live phone line at (720) 674-7312 is answered by a person, not a voicemail, any time you call.
Denver’s semi-arid climate and rapid temperature swings create a specific creosote problem. The dry air pulls moisture through masonry faster than in humid regions, and when homeowners burn their first fire after a 40-degree drop, the thermal shock can loosen existing buildup. We’ve swept chimneys in Baker, Park Hill, Stapleton, Highlands Ranch, and across the metro since 2009. In neighborhoods like Congress Park and Sunnyside, where 1920s bungalows share walls with new construction, we’ve learned to read the flue condition against the age of the home and the fuel type, not just the calendar.
Corrine Halstead leads our operation, and our background-checked, uniformed technicians arrive with license information visible, a text notification when they’re en route, and a written scope and price before any work begins. That’s Haven Standard Clause 1: H.A.V.E.N. means “Have it in writing.” No exceptions.
What Our Chimney Cleaning & Sweep Service Includes
Level 1 Inspection
A Level 1 inspection is a visual examination of the readily accessible portions of your chimney structure and flue, performed without specialized tools. You need this annually if your appliance, fuel type, and venting configuration haven’t changed and you’ve kept up with regular sweeping. At Level Two Chimney Denver, we still document what we can see with dated photos, even on a Level 1, because Clause 4 of the Haven Standard requires a photo record on every job, not just the ones where we bring the camera down the flue.
Level 2 Inspection
A Level 2 inspection is the camera-scan standard we helped make normal in Denver. We run a high-resolution video camera the full length of the flue liner, through the smoke chamber, and into the firebox, recording every joint, every crack, every area of spalling or delamination. You need this when buying or selling a home, after a chimney fire, following a weather event, or when you’ve changed appliances or fuel types. We pioneered this practice in 2009, before regulators or insurers required it, and that archive became Clause 4 of the Haven Standard. You receive the footage and our written findings before we discuss any repair.
Creosote Removal
Creosote is the tar-like condensation product of incomplete wood combustion, and it builds in three classes: flaky soot (Class I), crunchy chips (Class II), or glazed, hardened tar (Class III). Class III creosote is common in Denver because homeowners often burn pine or construction scrap for quick heat, then choke the air supply overnight, creating the cool, smoky conditions that glaze the flue. We remove creosote with rotary chains, whips, or chemical treatment depending on the class and thickness, and we measure what’s removed so you have a baseline for next season.
Soot Removal
Soot is the carbon powder that coats fireboxes, smoke chambers, and flue liners, and in Denver’s dry climate it becomes electrostatically charged, clinging to metal and masonry alike. Heavy soot reduces draft efficiency and can migrate into living spaces through the smallest gaps in the fireplace face. We use HEPA-contained vacuum systems and specialized brushes sized to your flue diameter, and we protect your floors and furnishings with drop cloths and vented containment. The soot volume and condition are noted in your written report.
Annual Sweep
An annual sweep is preventive maintenance scheduled before burning season, typically September through October in the Denver metro, though we work year-round. We recommend booking by early September because demand spikes with the first snow forecast, and the homeowners who wait often find themselves on a three-week backlog while creosote sits in the flue. Your annual sweep includes the inspection appropriate to your situation, debris removal, and a written condition assessment with photo documentation. We also check your cap, crown, and flashing for winter readiness.
Fireplace Cleaning
Fireplace cleaning addresses the firebox, hearth, and visible surround, not the concealed flue. We remove ash buildup, clean glass doors without scratching, and inspect the firebrick for mortar deterioration or thermal cracking. In Denver’s older homes, especially in neighborhoods like Capitol Hill and Whittier, we’ve found fireboxes rebuilt with standard Portland mortar that can’t tolerate the 1,200°F cycling of wood fires. We note this in your report and explain whether it’s cosmetic or structural, and whether it can wait.

Brands We Service for Chimney Cleaning & Sweep
We’ve serviced and cleaned hundreds of DuraFlex stainless steel liner systems in Denver homes, particularly in Stapleton and Lowry where 1940s ranch remodels often need a dropped liner to meet modern clearances. We stock DuraFlex components through Haven’s buying network, which means replacement sections or connector fittings don’t require a two-week order delay.
HeatShield cerfractory flue resurfacing is another specialty. We’ve applied HeatShield in dozens of Denver chimneys where the terra cotta liner is sound structurally but has minor gaps or surface spalling. The material is rated to 2,900°F, and we document the before-and-after camera footage per Haven Standard Clause 4. We also work regularly with Gelco chimney caps, Olympia Chimney stainless steel liners, and we source through our network to keep pricing honest on every component. Whether you have a DuraFlex, HeatShield, Gelco, Olympia Chimney, or any other make, we can inspect, clean, and repair it with OEM-compatible materials and a written warranty.

AfterSigns You Need Chimney Cleaning & Sweep Right Now
- Smoke backing up into the room. If your fireplace exhausts into the living space instead of up the flue, you likely have a partial blockage from creosote buildup, a bird nest, or structural liner damage. In Denver’s variable pressure systems, a blocked flue can reverse draft entirely during a cold front, pushing carbon monoxide and particulate into your home.
- A strong, acrid odor from the fireplace in warm weather. That sharp, tarry smell is creosote off-gassing as temperatures rise. In Denver’s intense summer sun, a south-facing chimney can heat the flue enough to vaporize accumulated deposits, and the odor means you have significant buildup that will ignite under the right conditions.
- Black, oily residue on the damper or firebox walls. This is Class III glazed creosote, the most combustible form. It cannot be removed with standard brushing and requires rotary chain treatment or chemical application. We’ve removed glazed creosote up to ¾-inch thick in Denver chimneys where the homeowner burned green cottonwood or pine exclusively.
- Visible cracks in the flue liner or pieces of tile in the firebox. Spalling liner tiles indicate thermal shock or age deterioration, and they create a path for heat and combustion gases to reach combustible framing. In Denver’s freeze-thaw climate, moisture penetration accelerates this damage, and a cracked liner turns a routine sweep into a safety-critical repair evaluation.
- It’s been more than 12 months since your last professional sweep. The National Fire Protection Association recommends annual inspection, and for wood-burning systems in regular use, cleaning as needed based on creosote accumulation. Denver’s combination of dry air, altitude, and temperature swings means creosote forms differently here than at sea level, and the one-year interval is a minimum, not a maximum.
Our Chimney Cleaning & Sweep Process - Step by Step
- 1
Schedule and confirm. When you call (720) 674-7312, a live person answers, checks availability for your Denver address, and sends a confirmation with your technician’s name and estimated arrival window. You’ll receive a text when they’re en route.
- 2
Arrival and protection. Your technician arrives in uniform with license information visible, lays protective coverings from the entry to the fireplace, and sets up HEPA-contained vacuum equipment before touching your chimney. We inspect the exterior first for crown, cap, and flashing condition.
- 3
Camera-scan inspection. For Level 2 services, we run the camera down the flue, recording liner condition, joint alignment, creosote class and thickness, and any structural anomalies. You watch the footage with the technician in real time if you’re present, or receive it by email with the written report.
- 4
Written scope and price. Before any cleaning or repair begins, you receive a written price, written scope of work, and written warranty terms. This is Haven Standard Clause 1. If we find conditions that require repair, we explain what the camera shows, what it means for safety and function, and whether it can wait or needs immediate attention. Nothing is recommended without evidence you can see.
- 5
Cleaning, documentation, and closeout. We perform the agreed work, clean all debris, remove our protective materials, and leave your fireplace area cleaner than we found it. You receive a dated photo record, the camera footage if applicable, and a written completion summary. Every job is backed by our 365-Day Done Right Promise.
How Much Does Chimney Cleaning & Sweep Cost in Denver?
A standard chimney sweep with Level 1 inspection in Denver runs $189-$249 for a single-flue, wood-burning fireplace in a home built after 1970. A Level 2 inspection with camera scan adds $60-$100, bringing the typical range to $249-$349. These prices assume normal creosote accumulation, accessible roof conditions, and no structural repairs needed.
Several factors move the price within or above these ranges:
- Fuel type and burning habits. A gas fireplace with minimal soot costs less to clean than a wood burner with Class III creosote. Homeowners who burn 24/7 through Denver winters need more intensive service than occasional weekend users.
- Chimney height and access. Three-story Victorians in Curtis Park or Five Points with steep pitches require additional safety equipment and time. We price this upfront, not as a surprise add-on.
- Insert or stove configuration. A freestanding wood stove with a connector pipe through a masonry chimney takes longer to disassemble, clean, and reassemble than an open hearth.
- Deferred maintenance. If it’s been three or more years since your last sweep, expect heavier buildup and possibly the need for chemical treatment or rotary chain removal, which adds $75-$150.
How to avoid overpaying: get any competitor’s written estimate and bring it to us for a free second opinion.

Frequently Asked Questions - Chimney Cleaning & Sweep in Denver
Chimney cleaning and sweep is the mechanical removal of creosote, soot, and debris from your flue, firebox, and smoke chamber, combined with a structural inspection of the venting system. You need it because creosote is combustible above 451°F, and a typical wood fire reaches 1,100°F, making an unswept flue a significant fire hazard. The NFPA recommends annual inspection, and cleaning as needed based on what the inspection finds. Call (720) 674-7312 for a free estimate.
A standard sweep with Level 1 inspection takes 45-75 minutes for a single-flue fireplace. A Level 2 inspection with camera scan adds 30-45 minutes for setup, filming, and review. Complex systems with inserts, multiple flues, or heavy buildup can run 2-2.5 hours. We schedule realistic windows and text you if your technician is running early or late. Call (720) 674-7312 to book.
