Don’t Let a Damaged Chimney Crown Turn Your Cozy Fireplace into a Costly Nightmare

Your chimney crown sits quietly at the top of your home, working tirelessly to protect your entire chimney system from the elements. This small concrete roof serves as an umbrella to protect the entire chimney and masonry brick from water damage and debris, nests, and other invasive organisms. While it may be out of sight and out of mind, recognizing the warning signs of crown damage early can save you thousands of dollars in repairs and prevent serious safety hazards.

Understanding Your Chimney Crown’s Critical Role

The crown is a concrete slab that sits atop the chimney, preventing water from seeping into the mortar joints and the joints where the roof butts up against the chimney. The chimney crown’s primary function is to guard against water damage. It is intended to prevent snow and water from entering the building because it sits on top of the chimney. When functioning properly, this protective barrier can extend the life of your entire chimney system significantly.

Key Warning Signs Your Chimney Crown Needs Immediate Attention

Visible Cracks and Missing Pieces

The obvious sign of chimney crown damage are visible cracks. If you can see visible cracks, even if they are very small, they need to be filled and fixed or else water can get inside. Another sign that you have a problem is if you see pieces of the crown missing. Even a tiny crack can let water into the system and cause extensive water damage.

Water-Related Issues Inside Your Home

If you notice water pooling in your firebox, it’s a good sign that your crown is damaged and no longer doing its job. Water damage or stains on your home’s interior walls is another sign that your crown may be compromised. If you see noticeable signs of moisture entering the fireplace (aka rust) there’s usually one way it’s getting in…

Deteriorating Masonry and Mortar

If you notice damaged, moist, crumbling mortar joints it’s a clear sign that moisture has gotten inside of your chimney… likely through the crown. When a chimney crown is damaged, it will allow water to seep into bricks and mortar, and during freeze-thaw cycles, the repeated expansion and contraction of the mortar will cause it to break down and fall out.

Spalling Bricks and Structural Issues

If you notice bricks, stones or whatever other material your chimney is made of, actually coming loose damage has gotten pretty bad. When water and salt has a chance to enter the chimney it puts pressure on the bricks until they eventually pop out of place. This is a serious warning sign that requires immediate professional attention.

Algae Growth at the Base

Algae growing at the base of your chimney means that water has come from the top of your chimney and migrated down to the base, which means your whole chimney is at risk of water damage. It is a clear sign your chimney crown is damaged.

The Hidden Dangers of Ignoring Crown Damage

The moment your chimney crown sustains damage, water and moisture will start to seep inside, wreaking havoc by causing your chimney to deteriorate from the inside out. The typical homeowner won’t discover a water leak until it’s already done significant hidden damage. This is why regular inspections are crucial for early detection.

If your chimney does not have enough mortar to hold the bricks in place, they could collapse. In extreme cases, if you don’t fix spalling bricks right away the entire chimney will need to be replaced.

Professional Solutions and Prevention

The best way to deal with a damaged chimney crown is to prevent it from occurring in the first place. By having your chimney inspected regularly by qualified chimney sweeps, you will save time and money by catching an issue with your chimney crown before it worsens.

Repair Options Based on Damage Severity

Minor cracks can often be addressed with professional sealing. If your chimney crown only has a few minor cracks it may be salvageable with a chimney crown sealant, which can be applied directly to the crown. A waterproof sealant prevents water from entering the brick, mortar and concrete and creating serious damage.

For more extensive damage, if your chimney crown has a crack or is missing pieces, it must be repaired with new cement. The chimney sweeps will build a wooden brace that matches the size and shape of the original chimney crown and then pour cement into it.

Why Professional Service Matters
