The severity and depth of chimney crown damage determines how much it will cost to get your chimney crown smoothed out.

Moss Clearing
If your chimney crown has moss growth, the cost to have it cleared away using eco-friendly, human-safe cleaning methods that help to prevent future growth ranges from $250 to $700.
Repairing a Cracking Chimney Crown
If your chimney crown is cracking, the price to fix the problem ranges from $300 to $2,200. The job becomes more expensive with multiple cracks. Expect your contractor to suggest a crown replacement if your estimate for repairing cracks exceeds $2,500.
Resurfacing a Chimney Crown
A resurfacing project that fills thicker cracks to create a smooth finish is an alternative to a full replacement that can cost between $800 and $1,200. Once damaged areas are filled, the entire surface of the crown is coated in a protective paint membrane.
Sealing a Chimney Crown
Chimney crown sealing is typically performed as part of a larger repair project instead of a standalone treatment once all cracks have been addressed. During the process, a waterproof sealant is applied to the crown to provide protection against the elements. Chimney crown sealing services typically cost between $175 and $600.
Replacing a Chimney Crown
If your chimney crown isn't salvageable, the cost for a full replacement is between $1,800 and $3,000.
Cost to Repair or Replace a Chimney Crown Yourself
Some people opt to purchase something called brushable chimney crown repair paint that forms a flexible waterproof membrane over a crown. Typically, this is a cement-based coating intended for repairing cracks and gaps in chimney crowns that sells for between $70 and $100 per gallon.
The cost of a new stainless steel chimney crown ranges from $400 to $600. While forming kits can be purchased for specialty crowns, this is not a common DIY project.

Homeowners can use a store-bought chimney crown repair paint for minor cracks—using safe ladder practices, of course. However, a DIY chimney crown repair may cause a homeowner to overlook serious crown damage that needs a more thorough solution to preserve the chimney and fireplace.
Installing a new chimney crown is a complicated process that involves forming a crown from scratch. It's not considered a DIY job for someone without masonry and concrete experience.
Frequently Asked Questions
Chimney crowns may be stone, concrete, or metal but most crowns are made of concrete. It’s not recommended to build chimney crowns with mortar (which is different from concrete) due to it’s weaker composition (especially when exposed to the outside elements). Most chimney crowns are custom made to fit your home’s specific chimney.
Chimney crowns are located above the final brick layer at the top of a chimney. It’s important to get regular chimney maintenance and inspection, because it is near impossible to spot chimney crown damage without getting on your roof.
No, chimney crowns and chimney caps aren't the same. While chimney crowns protect the area at the top of the chimney flue, an additional cap is still needed.
If properly constructed with the right materials, a chimney crown can last 50 to 70 years. If done poorly, your chimney cap could need replacing in 20 years or less.
Most chimney crowns cannot be seen from the street or yard. As a result, most homeowners are completely unaware that their damaged or deteriorating chimney crowns need repairs or replacements. Chimney inspections offered by contractors can verify any damage.
Cracked chimney crowns can cause leaks, which lead to more costly chimney repairs. Some small cracks in a chimney crown are normal and can be repaired with a sealant, but even small cracks that go ignored can lead to bigger issues. The purpose of a chimney crown is to protect the rest of the chimney from water, but also any other outdoor elements like debris and animals. Failure to fix a crack early could result in larger debris entering your chimney.
