Do you have cracks in your chimney?
Chimney damage and chimney cracks aren't something that can be avoided. Your chimney will crack eventually, as the weather continues to affect it year after year and your home may even settle as time goes on. Though inescapable, the cracks in your chimney should never be ignored! You can save yourself from more expensive repairs at a later date by having your chimney and fireplace inspected annually. Not only will you know IF your chimney is cracked (without needing to climb on your roof yourself), but you'll be able to find out what is wrong with it and the preventative maintenance that should be undertaken.
Sometimes, the damage to your chimney isn't visible from the outside. An important part of chimney maintenance is the upkeep of flue tiles. Whether your masonry chimney is used to vent a fireplace, woodstove or furnace, most have sections of clay flue tile stacked one on top of the other to form a liner called the flue. The flue liner should be tightly sealed to protect the integrity and efficiency of your chimney. But over time, hidden dangers can develop that will compromise the safety and efficiency of your chimney.
Gaps Between Flue Tiles
The combustion process in your fireplace creates noxious gases that can contain creosote/soot, carbon monoxide and corrosive chemicals. The purpose of your chimney is to safely vent these hazardous gases from your home. Flue tiles are typically sealed with mortar to keep these gases within the flue. Over time, however, the mixture of heat, moisture and chemicals will erode the mortar, leaving gaps or voids between flue tiles.
Cracked Flue Tiles
Flue tiles can crack due to “sudden occurrences” such as a previous chimney fire, lightning strike, or seismic event. Cracks may also be caused by poor workmanship or the ongoing settling of your home.
Flaking Flue Tiles (Spalling)
Years of exposure to corrosive chemicals and moisture from combustion can attack clay flue tiles, causing pieces of the flue liner to flake off or delaminate, a process called spalling.
Other common causes of chimney damage are:
- Water damage
- Poor design/Improper installation
- Drastic temperature change
- Improper seal on chimney crown
