Cracked Crown? EverCrown® to the Rescue!
If your home has a fireplace and chimney, you probably don’t think much, if at all, about the components. After all, the chimney sits way up there and is often out of sight and out of mind. But the chimney crown is a vital part of your chimney system, and when it falls into disrepair, you can end up with water damage, brick deterioration, and more. Knowing what your crown does and how products like EverCrown® can restore it is essential to protecting your chimney and home.

What is a Chimney Crown?
The crown is a concrete slab that sits atop the chimney. It covers and seals the masonry while leaving an opening for the flue liner to vent smoke and gases. Its main job is to shed water away from the chimney.
A properly built crown has a slight slope and overhang that directs rain and melting snow away from the brickwork below. When it’s intact, it acts like a roof for the chimney. But if it’s cracked or damaged, it becomes an entryway for water intrusion.
What Causes Crowns to Crack?
In a word: weather, particularly harsh winter weather. Common causes of cracking include freeze-thaw cycles, in which water seeps into pores and small cracks in the concrete, freezes, and expands, worsening the cracks. Improper construction is another problem. Crowns made from basic mortar instead of proper concrete are more likely to fall apart. Age and weathering can contribute to crown cracking. Ultraviolet rays, rain, wind, and snow weaken the crown over time.
What Happens if You Ignore a Cracked Crown?
Water entering through a cracked chimney crown can cause serious problems, including:
- Spalling bricks (flaking or crumbling masonry)
- Deteriorated flue liners
- Interior ceiling or wall stains
- Rusted damper
- Mold growth
In many cases, what starts as a small crack turns into a full chimney repair if you don’t fix the damage ASAP.
How EverCrown® Helps
EverCrown® is a professional sealant designed to protect and restore masonry crowns with minor damage. Applying this sealant to the crown’s surface creates a flexible, waterproof shield that seals cracks and gaps, giving you long-lasting protection. Instead of demolishing and rebuilding the entire crown, this product creates a seamless, durable membrane over the existing surface.
Here’s how it works.
Seals Existing Cracks
EverCrown® is elastomeric, which means it can flex with temperature changes. Unlike rigid patch materials that might crack again, EverCrown® moves with the chimney. It fills hairline cracks and bridges larger fractures, deterring water intrusion.
Waterproof Protection
Once applied, EverCrown® forms a waterproof barrier that prevents rain and snow from penetrating the masonry. This dramatically reduces the damage caused by the freeze-thaw cycle.
Extends Chimney Life
When you stop water and the damage caused by freezing and thawing, you eliminate many of the problems that happen with your chimney, problems that can significantly reduce its lifespan. EverCrown® can add years to the life of your chimney system for a fraction of the cost of major repairs.

Is EverCrown® the Right Solution?
EverCrown® works best when:
- The crown is cracked but not severely deteriorated
- There are no large missing sections of concrete
- The structure underneath is stable
If the crown is crumbling or improperly built, a full rebuild may still be necessary. A professional chimney inspection can determine the best approach.
