Chimney Cleaning Frequency

Having been in the chimney business for so long now, it is hard to keep track of the number of people who ask how frequently the chimney needs to cleaned. Many people think that it is based on number of uses. Others think that is has to do with whether or not you can stick your head up and see any debris or nesting. Although there are a few ways to gauge how frequently to have the chimney swept, these are not it.

Another code that sweeps follow is that of the Chimney Safety Institute of America, which states that after having accumulated 1/4″ of creosote build up the chimney should be swept, but sooner if any glazing occurs. This is a fairly difficult way to determine when the chimney should be swept, but is great if you are new to the home and are unsure about the chimney’s use over the years.

Finally, one last method of judging when the chimney should be swept has been procured from the National Fire Protection Association. Clause 211 states that “Chimneys, fireplaces, and vents shall be inspected at least once a year for soundness, freedom from deposits, and correct clearances. Cleaning, maintenance, and repairs shall be done if necessary.” This particular code takes into account that, even if your chimney has a stainless steel chimney cap, critters can still damage the cap enough to enter the chimney and fill it with debris that jeopardizes the integrity of your entire home. There also may be other types of deterioration occurring in the flue system. Generally the rule of thumb is to have it inspected before each burning season that you decide to use your fireplace.

Does my gas fireplace need swept?

Unless there is nesting material or other debris in your flue system, you should not need to have your chimney swept, however, it should still be inspected yearly by a gas fireplace professional according to the National Fire Protection Association (NFPA). While the serviceman is out, he can determine whether the chimney needs to be swept and will also determine the integrity of the flue system and be sure it is suitable for use.

Regular maintenance will keep your gas logs running efficiently longer; this includes yearly inspections and less invasive, at home maintenance. Using ACS Gas Log Carbon & Soot Remover regularly will help prevent odors and creosote build up if your gas logs begin to work inefficiently.

Chimney Sweeping: Importance of Documentation and Pictures

Thankfully, this does not occur frequently, but when it does occur this does not mean that the sweep did not do his job well. Taking digital photos of the flue system, every mortar joint, every flue tile, will help immensely when these problems arise. Often times after sweeping, all the chimney sweep can see is a thin, smooth glazing of creosote in the flue system. Such a thin layer does not seem to warrant rotary cleaning, nor does it allow the sweep to see exactly what is going on with the flue tiles themselves.

Creosote will then curl up into little flakes, making a perfect environment for a chimney fire to occur. If the flue system reaches a certain temperature, the creosote can combust and cause a roaring chimney fire.

Because such a situation is possible, it is absolutely crucial for a sweep to document his work in the home. If you have a sweep come into your home who has no documentation or cameras for pictures, it would be wise to promptly send him home. Remember, you will need pictures of your flue system to get money from your insurance for any repairs of a natural occurrence and you will need documentation of the sweep and procedures done for your own peace of mind.
