Find top rated chimney repair specialists in your area

If you light fires often, plan on a yearly sweep. Burn wood several nights a week? Ask your sweep whether a biannual schedule makes more sense. Even an idle chimney needs attention—skipping service invites animals, moisture, and hidden creosote that can spark a fire the next time you strike a match. When in doubt, book an inspection and let the pro set the right cadence.

A certified chimney sweep starts with a visual check from the firebox to the chimney cap. Next come flexible rods fitted with wire brushes that scrub soot and creosote from the flue walls. If thick, tar-like layers refuse to budge, the pro may apply a chemical treatment or rotary tool to finish the job. A final pass with a high-powered vacuum keeps debris out of your living room, leaving the system clean and ready for safe use.

A routine sweep with a quick inspection can wrap up in 45 minutes to two hours. If the flue is packed with heavy soot or glazed creosote, expect the pro to stay three hours—or longer—while they scrape, brush, and vacuum every surface. The extra time is worth it: a thorough job keeps smoke flowing out, not into your living room, and helps you avoid expensive repairs down the road.

Watch for thick, shiny creosote, smoke backing into the room, a strong tar-like smell, or fires that struggle to stay lit. Each warning sign points to restricted airflow and a higher risk of chimney fire. Call a sweep as soon as you notice one—or better yet, schedule annual service so these red flags never have a chance to appear.

Chimney sweeping has many benefits for both safety and efficiency. These include preventing chimney fires, improving airflow and ventilation, and preventing carbon monoxide poisoning. Cleaning also helps your fireplace burn wood and heat your home more efficiently, and it keeps smoke out of your living space, protecting your household and belongings.
