A leaky chimney can be confusing, dangerous and possibly quite expensive to fix if the problem isn’t taken care of in the early stages. When getting estimates to have your chimney leak repaired, consider working with licensed, certified chimney professionals, who bring a wealth of knowledge to every job.
Here’s some of that knowledge.
What causes a leaky chimney?
Chimney technicians generally consider any situation in which water is infiltrating the chimney system a “chimney leak.” This includes water coming in from the top of the chimney due to damaged or missing chimney cap or water getting into bricks and mortar.
Here are some common direct and indirect causes of chimney leaks:
- Damage to the masonry
- Issues with the chimney cap or no cap in place
- Cracked chimney crown
- Warped or deteriorated chimney flashing
- Earthquakes, house-settling, major hail storms
- Improperly built chimney footing
- Chimney fires
- Gale-force winds
- Ice dams around the chimney base
Get chimney leaks fixed quickly
What starts as a small leak in the chimney system will eventually turn into a major problem that could include widespread masonry deterioration as well as damage to building materials of your home near the chimney structure.
Leaky chimneys don’t get better – they get worse. Fortunately, a skilled chimney services professional can perform a thorough inspection and determine why the leak is happening, where it’s centered and what will be required to resolve it.
Spotting a leaky chimney
If you notice any of these common chimney-leak signs, now is the time to address the problem:
Water in the firebox – could be from major leaks in the masonry or water coming into the top of the flue
White staining on exterior bricks – usually means that water is penetrating the bricks, possibly through cracks
Crumbling mortar on the roof near the chimney – mortar-joint damage doesn’t necessarily mean the chimney is leaking, but it means it may start to before long
Damp sections of walls and ceiling – could point to a leak within the chimney system or some part of the roof
Musty smells coming from the fireplace – creosote and soot inside the flue will give off strong odors when excess moisture is present in the chimney liner
