Masonry Chimneys: Chimney crown is a concrete slab on top of your chimney. This keeps water from entering the top and helps seal off the flue. The crown should be angled down from the chimney cap to the edges of the chimney top.

Chimney Crown Repair: Keeping Your Home Safe

When you look at your chimney, the first thing you notice at the top is the metal chimney cap, right beneath it is the chimney crown. Both are crucial for protecting your chimney and fireplace from water damage.

The chimney crown takes a beating since it’s made of masonry and is directly exposed to the elements. During the summer, it deals with intense heat and heavy rains, while in winter, it’s buried under snow.

Masonry is tough, but it can absorb water. Over time, moisture combined with heat and sunlight can lead to small cracks. These cracks can trap water, which then freezes and expands, making the cracks bigger. Before you know it, your chimney crown is compromised, allowing leaks and damage to creep in.

If you start seeing signs of damage on your chimney crown, that’s where Guaranteed Chimney Service comes in. We offer the right repair options tailored to your chimney and budget.

Types of Chimney Crown Damage and Repairs

Minimal Damage: Crown Coat Repair and Sealant

Your annual chimney inspection is key to catching damage early when repairs are still affordable. Our technicians might find minor issues like hairline cracks or early spalling. In these cases, we can make masonry repairs and seal it with a waterproof coat to fill those cracks and keep water out.

Extensive Damage: Rebuilding the Chimney Crown

If the damage is more severe—think large cracks or significant spalling—it’s often best to rebuild the chimney crown. Our team can construct a new crown designed to direct water away from your flue and chimney surfaces, ensuring it flows onto the roof and into your gutters. We’ll also apply a waterproof sealant to help it last longer.
