Leaky Chimney Repair

Every chimney professional will tell you: water and chimneys don’t mix. But until someone figures out how to run a chimney entirely indoors and out of the rain and snow, we’re going to have to deal with the problems water causes for chimneys, the biggest of which is chimney leaks.

A leaky chimney can lead to expensive damage and unsafe operating conditions. The Chimney Guys has seen just about every type of chimney leak imaginable throughout the Greater Columbus, Ohio, area, and we’ve fixed them all. Here’s what you need to know.

Water spreads, and so does its damage. If ignored, a seemingly “simple” chimney leak can turn into a major problem, affecting many parts and functions of your chimney. This can include the following.


A leaky chimney often leads to masonry deterioration, resulting in a discolored chimney that leans to one side or collapses entirely.

Chimney liner

Water can eventually damage the chimney liner and cause dangerous combustion gases and intense heat to escape from the flue and move into the home.

Metal components

Constant contact with water can cause metal parts and components of the chimney system to become rusty and inoperable. The fireplace damper is one example.

Home building materials

A chimney leak can end up damaging the roof, attic, walls, ceilings, flooring and other parts of the home near the chimney.


Chimney flashing unseated by constant moisture opens a path for water to drain down into your home.


Water in the chimney system can lead to sooty, musty odors that spread throughout the house.

Chimney Leak Inspection and Repair

The first step in resolving a leaky chimney is a proper inspection. Our technicians will determine where the leak is coming from, why it’s happening, how much collateral damage has happened, and how to put an end to the problem.

Repairing a chimney leak may involve:

  • Brick replacement and masonry tuckpointing to restore the strength of the mortar joints
  • Repair or replacement of the chimney cap or chase cover, as well as the flashing that seals the gap between the chimney and roof
  • Chimney crown sealing, repair or rebuilding
  • Sealing the entire masonry surface with a strong water repellant

Why Do Chimneys Leak?

We think of a “chimney leak” as any situation in which water is getting into any part of the chimney system. Using that definition, a leaky chimney can be caused by:

  • Damaged or missing chimney caps
  • Cracked or deteriorated chimney crowns
  • Warped or rusted-out chimney flashing
  • Loose or spalling bricks in the masonry
  • Crumbling mortar joints between the bricks
