Why should you have your chimney swept and inspected?

One of the primary reasons for chimney sweeping is the removal of creosote, a combustible byproduct created when wood burns.

Creosote builds up on the interior walls of the flue over time. Even a thin layer can ignite if temperatures become high enough, leading to a chimney fire. These fires often go unnoticed by homeowners but can reach temperatures that damage flue liners, crack masonry, and spread fire to surrounding framing.

According to NFPA 211, chimneys should be inspected annually and cleaned as needed to reduce this risk. Regular sweeping removes creosote before it reaches dangerous levels.

Chimneys are designed to safely carry smoke and combustion gases out of the home. When that pathway is compromised, dangerous gases—especially carbon monoxide—can back up into living spaces.

Common causes include:

• Creosote buildup restricting airflow

• Animal nests or debris blocking the flue 

• Damaged or deteriorated flue liners

• Improper draft caused by structural issues

Carbon monoxide is colorless and odorless, making it especially dangerous. A chimney inspection verifies that the system is drafting properly and venting exhaust gases safely out of the home.

Many chimney problems start small and worsen over time if left unaddressed.

An inspection can identify:

• Cracked or damaged chimney crowns
   
• Deteriorated mortar joints
   
• Failing liners
   
• Loose or missing chimney caps
   
• Rusted or malfunctioning dampers
   

Catching these issues early often allows for minor repairs instead of major rebuilds, saving homeowners significant money and preventing further damage.

Water is one of the most destructive forces affecting chimneys. Once moisture enters the chimney system, it can lead to:

• Freeze-thaw cracking
   
• Spalling bricks
   
• Interior leaks and ceiling damage
   
• Accelerated liner deterioration
   

Chimney inspections help identify the most common water entry points, such as damaged crowns, missing caps, or failing flashing. Addressing these issues early helps protect both the chimney and the home itself.

Many insurance providers reference NFPA 211 when evaluating fire-related claims involving fireplaces and chimneys. In some cases, lack of routine inspection or maintenance can complicate or delay claims.

Additionally:

• Home sales often require chimney inspections
   
• Fireplaces being brought back into use should always be inspected
   
• Rental and seasonal properties benefit from documented annual inspections
   

Having a documented inspection provides peace of mind and protection for homeowners.

Even if a fireplace is used only occasionally, annual chimney inspections and regular sweeping are critical for:

• Fire prevention
   
• Indoor air safety
   
• Protecting the structure of the chimney
   
• Preventing costly repairs
   
• Meeting recognized safety standards
   

Following NFPA 211 guidelines isn’t just about compliance—it’s about keeping your home safe.
