Caps, Crowns & Waterproofing 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.
