Why Chimneys Get Dirty

Creosote and soot are natural byproducts of burning fuel, deposited on the inside of your chimney or flue pipe as a solid sticky, black layer that is highly flammable. This needs to be regularly cleaned from your chimney or flue pipe. To reduce build up and use fuel efficiently, keep your fires hot, and provide them with plenty of oxygen. Damping fires to keep them burning longer produces more smoke and solid by-products. On average, your chimney needs to be cleaned after every two cords of wood that are burned. An annual inspection and cleaning is recommended for most average wood stove users.

How the Chimney is Cleaned

Brushes are used to remove creosote and soot from the firebox, smoke shelf, elbows, and connector pipes. This is done from both outside and inside the house. Occasionally there is creosote buildup that cannot be removed by brushing. Professional chimney sweeps use chemicals to alter the composition of the hardened creosote and turn it into a powdery substance that can be easily removed. Chemical chimney cleaning products are available for use by homeowners. The Chimney Safety Institute of America (CSIA) cautions against using these products to replace professional, mechanical cleaning of the chimney. Homeowners should be aware that these products can loosen debris that can fall into hard to reach places in the chimney structure and cause malfunctioning of the chimney. In addition, professional inspection is important because it often reveals hidden problems with the structure of a chimney that would otherwise go unnoticed, and could be potentially hazardous.

Chimney Inspection for Proper Operation

A properly functioning chimney has enough draft to pull smoke out of your home and provide enough oxygen for hot, complete burning of wood to occur. It is important that your chimney is the right type and style for your firebox or stove. In addition, it should be installed properly in your home in compliance with building codes and manufacturer instructions. A well-designed system has the following performance characteristics:

* fires light easily and burn bright and hot.
* draft builds quickly.
* lighting fires does not cause smoke to fill room.
* opening the door does not cause smoke to spill out.
* when not in use, air flows into the stove.
* Cold air and bad smells do not come out.

Chimney inspections are done by certified professionals using state of the art techniques and tools. A malfunctioning chimney can allow carbon monoxide into your living space. It causes illness and death if it is inhaled in large amounts. For the safety of your family and guests is critical to that your chimney is maintained properly with annual inspections. You should also have carbon monoxide detectors installed on each floor of your home, as well as in sleeping areas. Carbon monoxide detectors can let you know if there are possible problems with the venting systems of your furnace, gas hot water heater, or gas stove and will keep you from being harmed from prolonged exposure to low levels of carbon monoxide.

Common repairs

The purpose of your chimney is two-fold. It must remove harmful byproducts created when fuel is burned, and it must carry excessive heat away from combustible items near the fire. Besides being cleaned and inspected each year, your chimney will also need occasional repairs to ensure that it is performing these functions properly. Top Hat has licensed masons on duty to perform these repairs.

* Firebox repointing and rebuilding—the firebox is the brick area where you build your fire; loose bricks and degraded mortar should be repaired.

* Mortar crown repair—the mortar crown is the concrete like surface at the top of your chimney that keeps water out of your flue; a cracked or broken mortar crown should be repaired immediately to avoid serious water damage

* Damper repair—A damper closes the flue when you aren’t using the fireplace so heat doesn’t escape through the chimney

* Flue repair —the flu is the internal part of the chimney that funnels exhaust from your fireplace to the outside; if it cracks, breaks, or is blocked by debris or creosote build up it is a safety hazard that needs to be repaired.
