Where this work happens

The part of the chimney caps, crowns & flashing deals with

  2. CrownThe concrete slab on top of the stack. Once it cracks, water goes straight into the masonry below. Masonry Restoration →
  3. Flue linerCarries smoke and exhaust safely up and out. Cracked or missing liners are the most common hidden problem. Chimney Liners →
  4. MasonryBrick or stone and mortar. Freeze-thaw cycles open the joints first, then the bricks start to spall. Masonry Restoration →
  5. FlashingMetal that seals the joint between the chimney and the roof, and the source of most leaks. Caps, Crowns & Flashing →

Caps, Crowns & Flashing questions

Before you book

Will waterproofing trap moisture in the brick?
Not with the right product. We use vapor-permeable repellents that let moisture escape as vapor while stopping rain from soaking in. Paint and sealers made for other surfaces do trap water and are not used on chimneys.
Is a cap really necessary?
A cap keeps rain, leaves and animals out of the flue and stops sparks landing on the roof. On an uncapped chimney, rain and animal nests are the most common problems we find.
How do you find a leak?
We check the cap, crown, masonry and flashing from the roof, and the attic side where it is accessible. Most leaks come from one of those four, and the fix depends on which.
