Chimney Waterproofing

Brick is a sponge. Every rain and snowmelt, it drinks in water that freezes, expands and breaks the masonry apart from the inside. A proper vapor-permeable water repellent stops the brick from absorbing water while still letting it breathe — which is exactly what prevents the freeze-thaw damage so common in Colorado.

Signs you need chimney waterproofing

• Brick looks worn, flaking or spalling
• White efflorescence staining on the surface
• The chimney is exposed to heavy sun, wind and snow
• You just had masonry or crown work done
• You want to prevent damage before it starts

The benefits

• Blocks water absorption that drives freeze-thaw damage
• Vapor-permeable — masonry still dries out, no trapped moisture
• Extends the life of brick, stone and mortar
• Reduces efflorescence staining
• Protects the investment in any recent repairs
