Rain, Rain, Go Away: Leaky Chimney Season is Here

Spring has sprung! With the warm weather also comes spring showers. The addition of rain can wreak havoc on your chimney. If water gets into the chimney, several detrimental issues can occur. Concerns of mold and mildew growing, causing possible health issues. Water within the chimney can also cause deterioration. We will outline what to look for and when to contact a professional to resolve the issue.

Is Your Chimney Leaking? Here Are the Warning Signs.

Musty Smells Coming From The Fireplace:

A musty smell coming from the fireplace is often a sign that moisture has entered the chimney. When water mixes with creosote, soot, and debris, it can create a damp, stale odor that seeps into your home, especially during humid or rainy weather.

Rust on Metal Chimney Components:

Rust on metal chimney components is a clear indicator that moisture is entering your chimney system. Parts like the damper, firebox, or chimney cap are especially vulnerable, and once rust forms, it can weaken these components and affect how your fireplace operates.

Deteriorating Mortar Joints:

Deteriorating mortar joints are a common sign that your chimney is being affected by weather and moisture over time. Mortar between the bricks can begin to crack, crumble, or fall out, leaving gaps that allow water to penetrate deeper into the structure. In the winter, when water freezes, the freeze-thaw effect accelerates the deterioration.

White Staining on Exterior Bricks:

When water gets into bricks and dries, you will see a white staining called efflorescence. The water draws out the natural salts in the bricks, forming this chalky white residue.

Sounds of Water Dripping in the Chimney:

A strong sign that there is an issue with water and moisture in your chimney. This often occurs during or after rain and may indicate a missing or damaged chimney cap, cracks in the crown, or compromised flashing around the base.

Spalling or Cracked Chimney Masonry:

A sure sign that moisture has penetrated the brickwork, causing damage. Again, the freeze-thaw concept expands the bricks, leading to cracks.

Water Stains on Walls and Ceiling:

Staining around the chimney on the walls and ceiling is a strong indication that your chimney is leaking. The stains may be yellowish or brown.

A leaky chimney may start as a minor nuisance, but it can quickly escalate into serious, costly damage if left unaddressed.
