Quick Help

  • How do I stop water from entering my chimney during hard rains?
    Let's answer a question with a question! Start at the top: do you have a Chimney Cap or Damper? If not, this will help prevent water from entering the chimney flue. If you already have a cap/damper, inspect the chimney's crown for cracks, cracks or separation around the roof flashing, and inspect mortar joints for severe cracks. Then, pour some water directly on the brick and watch how quickly it's absorbed. If it soaks in within a few seconds you know the chimney is vulnerable and you may need to waterproof your chimney with Water Repellant.


  • If the crown on the top of my chimney is starting to crack and deteriorate what can I use to repair it?
    If the mortar crown is loose, crumbling or severely deteriorated, it should be replaced with a new cast-in place concrete crown. However, if the crown is damaged but structurally sound, larger cracks and voids can be filled with a patching cement or high quality caulk then covered with Crown Coat.


  • What can I use to repair the minor cracks on my brick chimney?
    Crack Magic is a highly durable silicone elastomer (think of it as a paintable caulk) that is perfect for repairing cracks up to 1/8" wide. It's easily applied with a brush and dries in about 6 hours to a milky white film that will not significantly change your chimney's appearance!
