When it comes to chimney and fireplace repairs – big or small – we can handle it all.

What Is a Chimney Crown?

The chimney crown covers the top of your chimney from its edge to the flue liner, and directs water, snow, and sleet away from the chimney, protecting its brick and mortar. That means your chimney’s crown is bearing the brunt of the elements, and cracks, crumbling mortar, and other problems can arise over time.

Those cracks might look small, but they’re allowing water to leak into the masonry below – and if crown repairs aren’t done promptly, small issues can lead to major damage to your chimney and home.

How Can I Tell if My Chimney Crown Needs Repairing?

If you can see cracks, crumbled masonry, or chipping and flaking (known as spalling), or if you’re noticing chimney leaks, your chimney crown should be inspected by a certified Billy Sweet Chimney Sweep technician who can assess and explain the extent of the damage.

Crown repairs can vary widely, depending on the damage. Billy Sweet Chimney Sweep technicians can recommend the best course of action to ensure a long life for your crown – and your chimney.

What Are the Types of Chimney Crown Repairs?

A chimney crown that is still structurally intact with only moderate damage could benefit from a simple crown coat repair with a sealant, which is applied over the whole chimney crown to create a waterproof, long-lasting barrier.

If an inspection reveals more serious chimney crown damage, a high-quality repair can require a lot more work, possibly requiring the construction of a new chimney crown. In the past, many builders would simply use the leftover mortar from the chimney to add the crown on top. Now, we know that this is far from best practice, as mortar can wear down and crumble quite easily.

But no worries – if it’s needed, Billy Sweet Chimney Sweep technicians can construct a durable new crown that will protect your chimney for many years to come.

Our licensed and certified technicians will walk you through the state of your chimney crown’s damage, and share the best options for your home and a safe, fully functional chimney crown to protect it.

An improperly designed or poorly repaired crown – or one that’s constructed or repaired with improper materials – can quickly crack and fail. And because chimney crowns are always bearing the brunt of the elements, small problems can very quickly become major ones if left unaddressed.
