Is there a crown on your chimney right now? Perhaps you’re asking why this is such an important element of your chimney system and what a crown can execute for you. Or maybe it’s one you already own, but it needs to be in perfect condition. It is essential to maintain the strength of your chimney crown, as it is a crucial component of your chimney system regardless of your circumstances. Neglecting your chimney crown might result in several more severe problems with your chimney. You must understand the nature of chimney crowns and what is required to maintain the beauty of yours.

What are chimney crowns and what is their purpose?

The top masonry component of your chimney is called the chimney crown. It is constructed of mortar, stone, or brick and is positioned above the flue of the chimney. The crown serves as an obstacle against weathering and related problems to the chimney’s top. By covering and sealing the top of the chimney’s entrance along its edges, the crown provides this protection. It also benefits in directing moisture and water away from the chimney, which helps to stop degradation.

With regular upkeep, a well-constructed chimney crown ought to last for many years. However, the impact of rain, snow, ice, and wind may lead it to endure the elements and deteriorate over time.

Indicators That Your Chimney Crown Needs to be Fixed

Apart from soot, fumes, and smoke, there are other signs that your chimney requires repair. Find out about some more problems that should be looked out for in case a chimney collapses or maybe start a fire.


Gathering of Water

Your crown is likely damaged and no longer operating properly if you see water accumulating in your firebox. Call an expert for an examination as soon as possible to identify the cause and propose a suitable method of action if you see pooling water. This could be a sign of other chimney-related problems.



Steel and iron are ferrous metals that can be used to make flue liners, dampers, flashing, and chimney crowns. Rust grows over time when it comes into contact with rain, snow, humidity, and other environmental variables. Rusting is also more prevalent in older and less well-maintained objects. The component will eventually fail due to severe corrosion if it is not addressed.


Deterioration of mortar joints

Because of ice, water, and seasonal expansion, the damage to mortar connections may eventually disappear. When mortar deteriorates, it exposes the masonry to moisture, which worsens the damage. In addition, if you leave a chimney unattended, it may eventually fall as a result of a breakdown. The mortar and joints may need to be fixed by a specialist.


Falling Chimney

Sometimes you see a collection of chimney tiles inside your fireplace, which is not good news. Sliding tile is often an indication of a broken flue lining. While improper building and construction techniques might also be factored in, water damage is usually the main root of the issue. If left untreated, it will only get worse. Cracks let moisture in and have the potential to start a chimney fire. Consequently, if you locate tiles anywhere they shouldn’t be, it’s imperative to fix any damage so it doesn’t happen again. The mortar was damaged by crown cracks, and poor flashing is usually to blame.



Is there white discolouration on your chimney? Efflorescence is the word for this. On faces of natural stone, brick, and concrete, these salt crystallizations are frequently observed. When it occurs, a moisture problem is usually indicated. It is acceptable to have a modest quantity, but if it becomes too much, there should be worry. Efflorescence can speed up the deterioration of the mortar and brick since it frequently suggests a malfunctioning flue liner or a loose flashing. It is therefore necessary to hire a trained chimney specialist like A Step in Time Chimney Sweeps to fix the flashing around the crown or install a new flue or liner to prevent water from entering the chimney.

Which are the two Crown repair types?

Chimney crown restoration comes in two primary varieties: rebuilding and sealing. The type of repair required will vary depending on the extent to which damage has been done.

Chimney Crown Sealant: Sealing a broken chimney crown is a fairly simple and affordable repair procedure. Using a brush or roller, apply the sealant according to the manufacturer’s instructions. Selecting a sealant formulated especially for chimney tops is essential. Waterproofing chemical substances are also included in certain liquid sealants, which may assist in protecting the crown from additional water harm.

Crown rebuilding: Although this is a more complex repair, it needs to be done if the chimney crown is severely cracked. Rebuilding the crown involves removing some or all of it. A robust material, such as concrete, should be used for the replacement crown. To keep water from harming the brickwork, it must also be tilted and have an overhang or drip edge. Repairs should only be performed by a Certified Chimney Professional since rebuilding and repairing chimney crowns necessitate a thorough knowledge of the chimney system, standards in the industry, and building codes.

The Reasons Behind Choosing A Step in Time Chimney Sweeps for Your Chimney Crown Repairs

Because your chimney crown is so important in shielding your chimney from the harm that water can do, you must have it fixed by a qualified, experienced specialist. A crown that is inadequately constructed or repaired, or that is constructed out of the wrong materials, is at risk of cracking and collapsing rapidly. Additionally, as chimney crowns always face the worst of the environment, minor issues can easily turn into major problems if ignored.

With years of experience in the construction, maintenance, testing, and sweeping of chimneys, A Step in Time Chimney Sweeps can complete the task correctly.
