Chimney Waterproofing FAQs

Frequently Asked Questions

How often should I waterproof my chimney?

Quality waterproofing lasts 5–10 years. We recommend reapplication before signs of wear appear, especially in Oregon's wet climate.

Is waterproofing the same as sealing the crown?

No. Waterproofing protects the exterior masonry. Crown sealing addresses the concrete top. Both are important and often done together.

Will waterproofing change the look of my chimney?

No. Our breathable sealants penetrate the masonry and leave a natural, non-glossy finish that doesn't change the appearance.
