Factory Built Chimney Flue

These before and after pictures of a factory built chimney flue. That ugly matierial you see in the before is creosote. Creosote is a byproduct of incomplete combustion of wood, typically most prevalent when first starting a fire and when burning unseasoned wood. Creosote is very flamible and where large deposits accumulate in a chimney, a chimney fire is very possible and extremely dangerous. The normal temperature in a chimney during a regular fire would be around 500 degrees. When a chimney fire occurs the temperature can go as high as 1800 degrees. When they occur, they can destroy the chimney and set the house on fire. Removing the hazardous creosote and inspecting the chimney for safety and integrity are the two main purposes of a chimney sweep.

Chimney with cracked crown and flue

Here is a video chimney inspection we did where we found the chimney with a cracked crown and flue.

 

Chimney reline to address cracks and hazards in the flue

Cracks-and-voids-in-a-flueThere are several methods available.  The method we use has several advantages.  It is less expensive than a metal liner and the spray on solutions some companies use.   It is very strong and durable and cannot be brushed out with steel wire brushes.

Another advantage is that the HeatShield® system does not significantly decrease draft like a steel liner does.  A decrease in draft might cause the combustion gases to spill into the house.  HeatShield® is a specially formulated “Cerfractory®” sealant material that restores the integrity of your chimney’s flue to vent hazardous flue gases from your home. It eliminates the dangers in your chimney caused by gaps, cracks, and spalling for years to come. By using either the Repair System or the CeCure® Sleeve Relining System (depending on the defects found) your chimney will be restored to its original peak level of safety and efficiency.

40 Year old home with 3 cracked chimney flues

This is a video of a home in San Juan Capistrano that is approximately 40 years old.  All 3 chimneys had severe cracks and gaps in the chimney flue.  This is a severe fire hazard if the fireplaces are used to burn wood or gas fires.  If you are purchasing a home that was built over 20 years ago, don’t take a chance that the chimney will not have gaps.

Approximately 40% of the homes that were built in the 1980s and earlier have cracks and gaps within the chimney flues.  Regular home inspectors do not inspect the chimneys with a video camera and as a result most of the cracks are not detected.  Approximately 15,000 homes per year in the U.S. have home fires which start in the fireplace/chimney.

Traditional Masonry Chimney Flue

These before and after pictures of a traditional masonry chimney flue. That ugly matierial you see in the before is creosote. Creosote is a byproduct of incomplete combustion of wood, typically most prevalent when first starting a fire and when burning unseasoned wood. Creosote is very flamible and where large deposits accumulate in a chimney, a chimney fire is very possible and extremely dangerous.

When they occur, they can destroy the chimney and set the house on fire. Removing the hazardous creosote and inspecting the chimney for safety and integrity are the two main purposes of a chimney sweep. I get calls regularly from people who have had a chimney fire. It is commonly observed, when flame is shooting out the top of a chimney like a giant torch, with flame reaching 10 feet in the air. Quite a sight. Another call i get is people thinking a jet engine buzzed their house. When a chimney fire occurs it can make quite a roaring inside the house. I sometimes make the possibly poor joke, that a chimney fire can suck up small animals and children up the flue, so much air flow occurs to support the fire.
