Chimney Leaks and Water Damage


There’s almost nothing worse for a chimney than water penetration. A small crack and tiny amount of water can become hundreds and thousands of dollars worth of damage. Consequently, this is over just one burn season. This is because the freeze/thaw process that water experiences widens cracks in the masonry.  Shifting bricks, a weakening mortar, and making way for even more water to enter is just some of what you can expect.

Masonry is constructed of a variety of materials, all of which are adversely affected by water. Brick, mortar, concrete, stone, flue tile, steel, and cast iron all deteriorate. In addition, they become altered when they come into direct contact with water, or are penetrated with water.

Once water is inside the masonry it can cause a host of issues including:

  • Rusted damper assemblies, fireplace accessories, and glass doors
  • Deteriorated metal or masonry firebox assemblies, central heating system, and flue lining system
  • Rotting adjacent wood and ruined wall coverings and ceilings
  • Water stained walls, ceiling, and chimney exterior
  • Clogged clean-out area
  • Decayed exterior mortar and collapsed hearth support
  • Tilted chimney structure and chimney settlement

This type of damage is solely caused by chimney leaks and can be prevented.

Diagnosing Your Chimney Leak

The damage caused by water penetration isn’t noticeable right away. In fact, by the time these things are noticed, there is extensive damage unseen to the homeowner’s eye.

Three signs that mean you may have a leaky chimney include:

  1.  A stinky chimney, especially one that smells musty is cause from a leaky chimney.
  2.  Less efficiency is generally caused because of an issue such as a chimney leak. Water causes parts to work incorrectly as well as the draft is less effective.
  3.  Stains on interior and exterior masonry means that water is causing discoloration and the mortar has been penetrated.
  4.  Leaks and stains on interior of the house including walls and ceilings. The walls and ceilings don’t even have to be near the chimney because water runs to the lowest place, and then leaks through the weakest portion of ceiling or wall. Water can run several feet or rooms away from the chimney leak itself before physically leaking through the ceiling materials.
