Chimney Crown Repairs

Your chimney system has a complex design, with different parts that play different important roles, either to help vent gas and byproducts or to protect your home (and the system itself) against the effects of fire and water. Some of the parts that help your chimney battle water are:

  • the chimney cap, which is installed at the very top of your flue
  • the chimney flashing, which is installed where the chimney meets your roofline
  • the chimney crown, which is installed at the top of your chimney, just below the cap

Although all of these safeguards play key roles in keeping the chimney system dry, the chimney crown is particularly important.

What Is A Chimney Crown?

A chimney crown is generally constructed out of masonry or concrete, and sits horizontally at the top of your chimney, helping to divert rain, sleet and snow away from your flue’s opening. As you can imagine, with the elements constantly attacking it, the crown is under a lot of stress. It’s not uncommon for small cracks to form in the crown — if left unrepaired, water can work its way into these small cracks, making the damage far worse. As water in the masonry expands and contracts, it can turn small cracks into large cracks and cause the brick and mortar to crumble and flake.

A damaged chimney crown is a common cause of chimney system leaks. If you’re experiencing a chimney leak or have noticed cracks in your chimney crown, call Mountain Man Fireplace and Chimney! Our experienced technicians can assess the damage and recommend the appropriate chimney crown repairs.

Different Types Of Chimney Crown Repairs

If your chimney crown damage is less severe (small hairline cracks, for instance), Mountain Man Fireplace and Chimney can apply a crown coat sealant that will create a flexible and water-impermeable layer over the crown. This sealant will also seal the small cracks and equip the crown to properly repel water again.

More extensive crown damage may require more significant repair and even a full crown rebuild. If you do need to have a new crown built, Mountain Man Fireplace and Chimney technicians can build a proper and durable one and apply a waterproofing sealant that will help extend its service life.

If you think you might need to have your chimney crown repaired or rebuilt, call Mountain Man Fireplace and Chimney at 303-679-1601 — we’d love to help!

Not only are they very professional (taking shoes off, putting down floor protectors, etc.) but they were also very personable.
