What Is Chimney Waterproofing & Sealing?

Chimney waterproofing involves applying a breathable, penetrating sealant to the exterior masonry of your chimney. Unlike paint or non-breathable coatings, a proper chimney sealant allows moisture vapor to escape from inside the masonry while blocking liquid water from entering.

• Application of professional-grade breathable masonry sealant
• Pre-treatment inspection for existing cracks or damage
• Crown sealing and repair as needed
• Protection from freeze-thaw damage and moss growth
• Extends the life of mortar joints and brick faces

Protecting Your Home

Southwest Washington's wet climate is particularly hard on masonry chimneys. Moisture penetrates brick and mortar, then freezes and expands in winter — a process that accelerates deterioration dramatically. We use ChimneySaver, the industry-standard breathable sealant, which carries a 10-year warranty when professionally applied.
