As the saying goes, “hot air rises”, and so does the warm air in your home. The two key signs it’s time to clean your chimney are if you have more than 1/8 inch of soot and if you have any creosote in your chimney.
Conversely, mortar acts as the adhesive that holds the bricks together, forming a tight seal against external elements. Together, bricks and mortar provide the necessary structural support to keep your chimney standing tall and performing efficiently. A chimney crown is the concrete that covers the top of the chimney and prevents water from getting into the chimney system. A chimney crown covers the majority of the chimney, while the chimney cap shelters the flues that remain open for venting. Essentially, a chimney cap is a hat that covers a chimney to protect it against precipitation and debris such as leaves and branches.
If using leftover charcoal, make sure to remove as much of the spent ashes as possible, then fill the chimney half-full with fresh charcoal and add the leftover charcoal on top. This increases airflow in the chimney starter, since used charcoal tends to pack too closely together. Using old newspaper was the original way to light a chimney starter. The only problem with newspaper is that it’s messy…light ash blows out of the chimney around your patio after the paper burns.

After you look for damaged or improperly installed shingles you can look for nearby roof interruptions such as plumbing vents, dormers, attic fans. Any time you have something coming out of your roof, there is a potential leak. The most common cause of chimney leaks is due to what’s called a “sponge effect”. The more it rains, the more water it holds until it is completely saturated. The water eventually makes its way out of the masonry at a lower level – sometimes into your home.

A closed throat damper will cause smoke to fill your house immediately when you start a fire.

What Happens During a Chimney Fire
Extreme temperatures will affect nearby combustible materials if the liner isn’t fully intact. The heat will cause pyrolysis, which lowers the temperature necessary for the materials to ignite.
