Don’t Let Water Destroy Your Home: The Critical Importance of Chimney Crown and Cap Repair

Your chimney’s crown and cap serve as the first line of defense against water infiltration, yet they’re often the most overlooked components of your home’s protection system. At the highest peak of your home, your chimney cap (what covers the flue opening) and crown (what protects the top of the chimney) keep water, animals, and debris from entering your fireplace. If your cap or crown is missing, damaged, worn, improperly installed, or otherwise ineffective, your chances of incurring water damage and other problems significantly increase.

Understanding Your Chimney’s Protection System

The chimney crown is the upper-most portion of the chimney. Its purpose is to allow smoke and fume to vent through the flue to prevent moisture from getting inside. The lip of the crown is sloped to direct moisture away from the chimney. Meanwhile, chimney caps act as a barrier, preventing rain and debris from entering, essentially functioning like a roof for your chimney – every chimney needs a chimney cap for the same reasons every home needs a roof!

Since your crown and cap is at the very top of your masonry structure, it acts like a helmet or a solid umbrella for the entire fireplace and chimney system. The crown essentially becomes the protector, responsible for keeping the inside of your fireplace and flue safe and dry.

The Hidden Dangers of Crown and Cap Damage

Water damage from compromised chimney crowns and caps can be devastating and expensive. The most typical issue with concrete chimney crowns is cracking. Moisture settles in, and over time, freezing and thawing causes the concrete to crack, which allows more water in, and thus the cycle continues. Mortar cap crowns frequently form hairline cracks the very same night they set up! In no time, these small cracks begin to leak, fill with rainwater, freeze and then widen. Regrettably, a broken crown turns into loose brickwork at the top of the chimney in a few short years.

The financial consequences are significant. A cracked chimney crown or spalling bricks can easily cost $1,000 to repair. And, if left untreated, the damage can accelerate quickly, and cost you upward of $3,000. In addition to causing brick damage, leaks due to a damaged crown will lead to rusted fireplace doors, ruined dampers that cannot be opened or shut because they’re so rusty, or loose bricks in the fireplace’s firebox.

Warning Signs You Need Professional Attention

Homeowners should watch for several key indicators of crown and cap problems. If your chimney’s crown is damaged or your cap is missing or loose, you may notice concrete, pieces of brick, signs of animal activity, or other debris accumulating in your firebox. Of course, if debris enters, water and snow can also. So, if you notice any debris around your chimney’s foundation or in your firebox, it’s important to schedule maintenance and repairs as soon as possible.

Other warning signs include water stains or discoloration both inside and outside of your home, and cracks in the mortar, which is in between the bricks or stones – these serve as prime entry points for water infiltration.

Professional Repair Solutions

The approach to repair depends on the extent of damage. If there are a few small cracks in the chimney crown but it is otherwise intact then sealing the crown is a viable repair option. Sealing the cracks will prevent any more moisture from leaking between the walls and flue inside the chimney. Sealing the chimney crown with crown sealer, a flexible elastomeric coating, is the best way to stop existing cracks from spreading and prevent new ones.

For more extensive damage, repairing the chimney crown is a better option when there are more significant, hairline cracks in the surface. When repairing the crown, a skilled mason carefully fills the cracks with a patch cement material. The entire chimney crown is then sealed with a waterproof sealant to protect the surface.

The Importance of Professional Installation

In most cases, servicing chimney caps and crowns is not recommended except by qualified professionals. Anything performed above a couple of feet in the air is dangerous and can result in serious injury or worse. Additionally, expert masonry companies have specialized training, skills, knowledge, tools, and equipment needed to perform the work correctly and safely.
