Professional Chimney Sweeping: Keep Your Home Safe & Efficient

Over time, the combustion of wood and other fuels produces creosote—a sticky, tar-like substance that adheres to flue walls. Even a thin layer of creosote can ignite at high temperatures, causing a chimney fire that spreads to surrounding framing. Regular chimney sweeping removes these deposits, reducing the risk of fire.

A clean flue also improves draft, allowing smoke and gases to vent properly. Poor draft leads to smoke backflow, carbon monoxide buildup, and reduced heating efficiency. By sweeping your chimney annually (or more if heavily used), you maintain healthier indoor air quality and lower energy costs.

Home insurance companies often require proof of professional chimney cleaning for policy renewal. Additionally, real estate transactions typically mandate a certificate from a licensed chimney sweep. Scheduling regular sweeping ensures compliance with insurance and safety codes.

• Brush & Rod System
  Traditional method using a set of flexible rods and a wire brush. The sweep lowers the brush from the top of the chimney and rotates it to scrape off creosote and soot.
• Whiskbroom & Paddle System
  Utilizes a paddle-shaped brush attachment, especially effective for prefabricated metal chimneys. The sweep inserts the paddle from the top and moves it in a sweeping motion to dislodge debris.
• Power Sweeping (Rotary System)
  Employs a motorized drill attachment with rotating brushes or brushes on flexible cables. This method is ideal for removing heavy creosote deposits and cleaning long flue runs efficiently.
• Vacuum & Containment System
  A high-powered vacuum and containment bag capture soot and debris at the chimney base, preventing dust from entering the home. Often used in conjunction with brush-and-rod or rotary systems for a clean workspace.
• Video Flue Inspection
  After sweeping, a video camera probe inspects the liner to confirm all creosote and obstructions are removed and to detect hidden cracks or damage requiring repair.

1. Pre-Sweep Inspection: The sweep examines the firebox, damper, and accessible flue areas to assess creosote levels and chimney condition. They note any structural concerns—like cracks or missing mortar—that need addressing.

2. Containment & Safety Setup: Drop cloths and protective barriers are placed around the hearth to catch falling debris. A high-efficiency vacuum and containment bag are set up to collect soot and dust, preventing it from dispersing into living areas.

3. Sweeping the Flue: The technician climbs onto the roof, lowers a brush and rod system or rotary brush assembly into the chimney, and uses a rotating motion to scrape away creosote and soot. The dislodged debris falls into the firebox for collection.

4. Firebox Cleaning: After sweeping, the technician uses a stiff-bristled brush and vacuum to clear remaining debris from the firebox, smoke shelf, and damper area. Removal of ash and soot prevents future buildup.

5. Video Flue Inspection: A flexible camera probe is inserted into the chimney to verify thorough cleaning. This inspection ensures no hidden creosote pockets or debris remain and helps identify flue liner cracks or leaks.

6. Post-Sweep Assessment: The sweep reviews findings, recommends any necessary chimney repairs—such as creosote removal treatment or masonry restoration—and provides a written service report.

7. Safety Testing: Finally, a draft test is performed to confirm proper airflow. The technician ensures your appliance vents correctly, preventing smoke backflow and carbon monoxide hazards.

Comprehensive Creosote Removal: Certified sweeps use industrial-grade brushes and vacuums to remove all layers of creosote, including hardened deposits that pose the highest fire risk.

Detailed Safety Inspection: A professional inspection identifies hidden flue liner cracks, masonry gaps, or animal nesting, preventing costly repairs and unsafe conditions.

Improved Heating Efficiency: A clean flue promotes optimal draft, reducing smoke spillage and ensuring your fireplace or wood stove burns cleaner, saving on fuel costs.

Guaranteed Code Compliance: Professionals stay up to date with local building and fire codes. Their license and insurance ensure your chimney meets regulatory requirements and that you’re covered in case of accidental damage.

How often should I have my chimney swept?

The National Fire Protection Association (NFPA) recommends sweeping at least once per year. If you burn wood frequently or use a pellet stove, consider a semiannual sweep to remove creosote and debris buildup.

What is creosote and why is it dangerous?

Creosote is a black, tar-like substance created when wood smoke condenses on cooler chimney walls. Highly flammable, it can ignite at high temperatures and cause a devastating chimney fire. Regular chimney sweeping removes creosote before it accumulates.

Can I sweep my own chimney?

Homeowners can perform a basic DIY sweep with hand brushes for minimal buildup. However, a professional chimney sweep has specialized equipment, vacuums, and safety gear to remove stubborn creosote layers and inspect for hidden damage.

How much does professional chimney sweeping cost?

Costs vary by region and chimney complexity. On average, a standard chimney sweep ranges from $100–$200. If extensive creosote removal treatment or video inspection is required, pricing may increase to $200–$300. Always request a written estimate upfront.
