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.

    Well a new year is upon us and during this time in late Jan the temps are running above normal. This will end I hear the middle of Feb with temps coming back to normal and COLD..

    We still get a lot of folks calling to ask for a second opinion where another local company was call and they found a LOT of stuff wrong with your 20 plus year old chimney most of the time with a quote of 4-5K or more.

    A lot of the things they "recommend" are to bring your chimney up to 2018/2019 code standards which is not necessary unless you are doing major repairs on the chimney or it is being torn down and rebuilt.

    Chimneys built in the 60 and 70's had different code requirement than a chimney built in 2018/2019.


    PS, If you have gotten a quote for chimney repairs, ie.. you need a chimney liner -liner work, parging smoke chamber etc. or you have been told "you might burn your house down" or "this could create a problem" stuff, that seem HIGH give us a call and let see what we can do for you.

  • Woodburning and gas burning fireplaces. Are they ready for winter.

    Is your Fireplace or Gas Logs ready to go.. If not or for a service give us a call.

    In a power outage a fireplace or gas logs may be your only form of heat so make sure they are working in top form. Give us a call to set up appt 919-772-8110

    have a good week

    PS: if you do NOT have a Carbon Monoxide detector and you have gas logs.. GET ONE.. NOW... I recommend the combo CO / Smoke battery powered detectors at Lowe's Home depot or most hardware stores..

    If yours are over 10 yrs old replace it.. (there's a date on back) If there is not a date of manf on back GET rid of it.
