Everything you need to know about chimney cleaning, inspections, pricing, and keeping your fireplace safe.
A chimney sweep removes soot, creosote, and blockages from chimneys, fireplaces, and flues. The goal is to improve air quality, prevent chimney fires, and keep your heating system efficient.
Most experts recommend cleaning your chimney at least once a year, ideally before the heating season begins. If you use your fireplace heavily, plan on two cleanings each year.
In the United States, chimney cleaning typically costs between $150 and $350. Pricing varies by location, chimney height, and the amount of buildup. Inspections or repairs usually add to the total.
A professional chimney sweep will:
Inspect the chimney and fireplace
Protect surrounding furniture and flooring
Use brushes or vacuums to remove soot and creosote
Check for cracks, blockages, or structural issues
Provide a report on any recommended repairs
Common warning signs include:
A smoky or musty smell even when the fireplace is not in use
Soot or debris falling into the firebox
Smoke that does not draft properly
Thick, tar-like creosote buildup
Animals, nests, or leaves inside the flue
It is possible, but not recommended. Professional chimney sweeps have specialized tools and inspection cameras that ensure a thorough cleaning and help detect hidden safety hazards.
Note: DIY cleaning can miss dangerous buildup or unseen damage.
Most chimney cleanings take between 45 minutes and 90 minutes, depending on the chimney's size and condition.
A chimney sweep focuses on removing soot, creosote, and debris. An inspection evaluates the chimney's safety and structure. Most professionals offer both services together.
Level 1: A basic visual inspection for annual maintenance.
Level 2: Includes a camera scope and is required when selling a home or after a fire or major event.
Level 3: An invasive inspection if serious damage is suspected, which may require removing parts of walls or the chimney.
Schedule a professional inspection each year. Warning signs include cracked mortar, missing bricks, smoke backing into the room, or strong odors. Stop using the fireplace until it is inspected if you notice these issues.
Yes. Gas fireplaces still produce residue, and their venting systems can become blocked by dust, debris, or animal nests.
Creosote is a black, tar-like substance created when wood burns. It is highly flammable, and buildup is one of the leading causes of chimney fires.
Look for the following:
Certification from the Chimney Safety Institute of America (CSIA) or the National Fireplace Institute (NFI)
Verified customer reviews
Proof of insurance and local licensing
Clear, transparent pricing
Late summer or early fall, before you regularly use the fireplace. That timing ensures the flue is clear of blockages and ready for the heating season.

Chimney cap installation
Fireplace and masonry repair
Chimney relining
Dryer vent cleaning
Waterproofing and leak prevention
Reputable chimney sweeps are certified by the CSIA or NFI. Always ask for proof of certification before scheduling service.
Follow these best practices:
Schedule regular cleanings and inspections
Burn only dry, seasoned wood
Install and maintain a chimney cap
Use smoke and carbon monoxide detectors
Avoid overloading the fireplace with fuel
Stop using the fireplace immediately and contact a certified chimney sweep. Blockages are commonly caused by bird nests, leaves, or heavy creosote buildup.
Routine maintenance is usually not covered. However, fire, storm, or accident damage may be covered if those events are included in your policy. Check with your insurance provider for details.
