Chimney Crown Repair

A lot of chimneys crowns we see have cracks in the crown mortar which are in need of repair, that can allow water to enter the chimney structure.

When a brick chimney is built the masons use a type “S” or “N” motor which is good for building the chimney structure.

The problem with most chimneys is the crown or top of chimney is formed with the same mortar they were using to build the chimney.

The proper mixture for a chimney crown is Portland cement product. I have almost NEVER seen this used, most of the time it’s the regular brick mortar mix.

The problem is regular mortar will get shrink cracks about day 10 of drying. If built during summer it can happen quicker.


his is a standard chimney we see.



his is what they look like after years of exposure to
sun, rain, freeze thaw cycles etc. the rust is from cheap
chimney cap.

ere you see the mortar missing on crown.





We use a product called Crown Coat. Its a flexible product that sticks to the mortar and allows the crown to expand and contract as needed during the heating of the day.

Your chimney has 5 sides.. 4 vertical and 1 horizontal “side”.

Think how the sun moves across you home during the day. The chimney can get sun on one side in the morning, the top around noon and the other side in the afternoon. The crown is the only “side” attached to all sides.

    Sarah and Will Gilfillan

    Owning and operating Chimney Keepers for 27 years has been a very rewarding experience, and we have enjoyed the relationships we have built with our customers. We are now starting a new chapter and are selling the business to one of our Technicians. Though we will miss the many relationships and friendships we have built over the years, Karen and I are looking forward to traveling full time in our Airstream as we explore the nooks and crannies of North America.

    We would like to take this opportunity to introduce you to Will and Sarah Gilfillan, who will be taking over Chimney Keepers as of March 30, 2020. Rest assured, Will has been well trained (by Carl!) and is very competent, with nearly four years of experience in the gas log/fireplace/ chimney service industry and over ten years as a firefighter. Sarah, the Office Manager/wife is a fast learner, and will do wonders in assisting you with scheduling appointments and answering questions. It was important to us to find a good fit for our customers, and we feel confident that you will find Will and Sarah to be knowledgeable and a pleasure to work with.

    Thank you for your business over the years. It was my distinct pleasure to have been of service to you, and I wish you continued success and prosperity in the years to come.

    Sincerely, Karen and Carl Newton

  • Is Your Wood-burning or Gas-burning Fireplaces ready for Winter?

    Is your Fireplace or Gas Log unit ready to go? If not, or for a service, give us a call.

    During a power outage, a fireplace or gas log unit may be your only form of heat, so make sure they are working in top form. Give us a call to set up an appointment, 919-772-8110.

    PS: If you do NOT have a Carbon Monoxide detector and you have gas logs, GET ONE… NOW… We recommend the combination CO/Smoke, battery-powered, detectors found at Lowe’s, Home Depot, or most hardware stores.

    If yours are over 10 years old, replace them (there’s a date on back). If there is not a date of manufacture on the back, GET rid of it.
