Inspections can reveal unsafe and deteriorating conditions due to corrosive gases venting through the chimney. Inspections can also uncover hidden blockages or damages to the inside flue liner, which can cause carbon monoxide to leak into living space or a passage way for fire to spread through your home.
When considering cleaning, there are a lot of variables involving how much creosote forms in a chimney. The type of wood, how seasoned the wood is and how hot you burn your fireplace and woodstove all play a factor. As a general rule, you should not go longer than 3 years without having your chimney looked at. If you burn everyday when it’s cold, your chimney should be checked every year.
