Chimney Crown Repair / Replacement

What is a Chimney Crown?

A chimney crown is the masonry top of your chimney. It should extend out more than the rest of the chimney, but yours may be flush with the rest of your chimney. It should also slope out, guiding water away from the chimney and protecting the vertical brick and mortar of the chimney.

Sometimes a chimney will speak to a homeowner and indicate that it has some problems that need to be addressed, but not always. Some symptoms that might indicate you have a problem with your chimney are:

  • Smell coming from the fireplace
  • Water dripping in or around the fireplace
  • White powdery staining in the firebox
  • Smoke drafting into the room rather than up the chimney when you start a fire
  • Broken/chipped bricks near the chimney top
  • Visual cracks in the brick or cement

Other problems might be harder to diagnose without a Certified Chimney Sweep® making a visit to your home for inspection and annual chimney sweeping. And some of these issues might have other solutions as well, hence the reason it is so important to have a chimney sweep diagnose your problem and come up with a chimney repair solution.

A proper chimney crown is built to last years, even in the Illinois weather. However, the chimneys in most homes, especially newer homes, are not usually built with chimney usage in mind and sometimes not built by chimney professionals. A correct cement crown will be cast and formed with a reinforced Portland cement-based mixture with at least a two inch overhang from the vertical chimney. It will have a bond break between the bricks and the cement, and have an expansion joint around the flue tile(s).

  • Sometimes a home inspection will skip the chimney inspection.
  • Sometimes a homeowner will neglect regular chimney inspections.
  • Sometimes the weather is so bad that even the hardiest chimney crown can’t compete with the weather.
  • Sometimes the homeowner over fires the components with too large a fire.

These are all out of your, the current homeowner’s, control. Moving forward, a proper chimney inspection on a regular basis will keep you informed of your chimney’s health.

A Certified Chimney Sweep® will be able to inform a homeowner if a chimney’s crown should be sealed or if a chimney crown needs replacing. If the chimney deterioration is bad enough that there will be a negative effect on your home or chimney system, your chimney sweep will discuss some options with you to properly repair or replace your chimney crown.

Back To Services

“Fantastic service by Terry and his team. I have a wood burning/gas fireplace that needed cleaning and to check for animals that I had heard near the chimney. They did a thorough cleaning (and kept the house clean while doing it!) and found no evidence of animal activity. Terry showed me that the previous owners had tapped into the gas line incorrectly and had used copper pipe for the gas to the fireplace. They removed (at my request) all gas components and the fireplace is now safe and set for wood burning (I can have it changed back to gas in a safe manner later). I'm very grateful that they found and fixed the possibly dangerous situation and did a wonderful job on everything else. I highly recommend Valley Chimney!”
