WOOD BURNING FIREPLACE
Masonry/brick fireplaces are found in older homes and upper end homes built today. Typical uses are wood burning, or an installed ceramic gas log set. For your wood burning fireplace, if you burn a cord of dry seasoned wood every year, you should clean every year. For your gas log set if it is used every night, clean every year, if used only on your colder winter nights, clean every 2 to 4 years.
(Rule of thumb on gas logs is, if there is a lot of soot build up on logs and back fire box wall it need’s to be cleaned)
