The Complete Guide to Chimney Inspection + Checklist

It’s easy to overlook chimney inspection when you’re inspecting the house. You probably think, “It’s standing straight, so it’s fine.” But that’s just the façade. There’s a lot more to a fully functional chimney. Also, a broken chimney can cause safety hazards, so you must take chimney inspection seriously. Let’s dive into the process of inspecting a chimney.

What is a Chimney Inspection?

A chimney inspection is the examination of all parts of a chimney to ensure its full functionality. The inspection prevents chimney-related hazards such as chimney fires or carbon monoxide intrusion.

Importance of a Chimney Inspection

The importance of chimney inspection lies in the prevention of chimney-related incidents and the overall efficiency of your home. Aside from the safety hazards, ignoring chimney inspection can be subject to the violation of regulatory standards. These incidents include:

• Poor ventilation due to blockage
• Rain water leaks
• Structural damages such as cracks or missing mortars
• Malfunction in the heating system

Different Levels of Chimney Inspection

Depending on thoroughness and difficulty, a chimney inspection is categorized into three levels.

Chimney Inspection Level 1

Level 1 chimney inspection is the simplest of all levels. You don’t need any particular equipment for level one inspection as the inspection is limited to readily accessible chimney components such as the exterior, chimney connectors, and other visible chimney appliances.

Chimney Inspection Level 2

Level 2 chimney inspection is performed when you’re inspecting the chimney for the first time, as in the case of moving into a new home. Also, if the house has experienced extreme weather events or an earthquake, it needs level 2 inspection. At this level, inaccessible and inaccessible parts, such as the flues, are tested using a camera.

Chimney Inspection Level 3

Level 3 chimney inspection is required when the chimney structure is severely damaged. This level involves the most complete inspection which is followed by rapid and extensive repair. You would need different tools for level 3 chimney inspection, depending on how badly the chimney is damaged.

Main Points of Chimney Maintenance

Regular chimney maintenance can ensure the longevity of your heating system and prevent costly repairs. By addressing the following points, you can keep your chimney in good condition.

• Clear obstructions: Bird nests, leaves, and other debris can block the airflow and push the smoke back into the house.
• Creosote removal: Creosote is a flammable substance in the form of thick liquid that builds up inside the liner over time. Regular cleaning avoids the risk of chimney fires caused by creosote abundance.
• Repair cracks in the chimney liner: Even small cracks in the chimney liner can lead to structural damage and gas leaks.
• Check the chimney cap and flashing installation: The cap protects the chimney against rain or snow, and the flashing prevents water from seeping into the structure around the chimney base.
• Monitor moisture levels: Look for signs of water damage, such as staining, crumbling bricks, or mortar deterioration. Waterproofing the chimney can extend its lifetime.
