The Most Common Chimney Installations & Replacements
The chimney installations and replacements you encounter will depend on the type of furnace, fireplace or wood stove you have. However, we have found that there are several things that come up over and over again and deserve mentioning.
Top 2 Installations & Replacements
The 2 most common installations & replacements are the:
Of course, there are other parts to look at as well. Below you will find 4 additional items that typically need to be replaced from time to time:
Metal Chimney Surrounds
Chimney surrounds are a great solution for covering up that big metal pipe sticking out of your roof. Unfortunately, older chimney surrounds may become deteriorated or rusted over time and need to be replaced.
Smoke Chamber Repair
Inside your masonry fireplace, there is an area called the smoke chamber, which is located above the firebox and at the base of the chimney flue. It is in this area that smoke gathers before it is exhausted up and out the chimney. To protect the integrity and efficiency of your fireplace:
- The smoke chamber should be free of any gaps, cracks or jagged edges.
- The corbelled areas of the smoke chamber should be coated with an insulating, high-temperature mortar to fill any gaps and smooth out any jagged edges.
According to the National Fire Protection Association (NFPA), defective smoke chambers are the third leading cause of chimney-related house fires. Because the smoke chamber is a “high heat” area, any gaps, cracks or holes can allow excessive heat to attack any surrounding wood or combustibles. The jagged corbelling slows the draft and will provide more surface area for highly-combustible creosote and soot to form.
Factory built fireplaces (prefabricated / zero clearance) systems have a covering at the top called a chase cover. It is a good idea to replace it with a stainless steel cover rather than a galvanized steel cover. Over time, some chase covers develop holes allowing water to penetrate the system and causing water damage. At Clean Sweep of Anne Arundel County, we will measure and custom fabricate a new stainless steel chase cover correctly sized and designed to shed water.
