The Dangers of a Leaking Chimney

We use the term “chimney leak” to refer to any situation in which outside water is getting into a chimney system. After 30+ years in business, our team has seen the worst possible water damage to chimneys and homes. We know the causes of leaky chimneys and what leaks can do. We also know how to fix the problem.

How Water Invades a Chimney

Water is pretty sneaky. It has many ways to infiltrate a chimney system, such as:

  • Through a damaged chimney cap at the top of the chimney
  • Through a cracked chimney crown below the cap
  • Through broken bricks in the masonry
  • Through decayed mortar joints between the bricks
  • Through warped or rusted-out flashing that covers the gap between the chimney and the roof

One of the problems with water intrusion is that you may not know about it until a lot of unseen damage has happened. This is why it’s a smart idea to have our licensed chimney inspectors look at your chimney and fireplace system once a year. We know how to spot early signs of a leaky chimney and resolve them correctly.

What Water Does to Chimneys

Incoming water can lead to many problems. Here are four of the most common:

1. Ongoing deterioration of masonry, possibly resulting in a leaning or collapsed chimney.
2. Rotting in roofs, attics, walls and ceilings that requires costly repair work.
3. Damage to the chimney liner that safeguards your home from smoke, flames and deadly carbon monoxide.
4. Mold outbreaks that spread away from the chimney and through the house.
