Consider Water Repellent for a Chimney

Waterproofing is a great way to add years to your chimney. It helps protect it long term because all masonry chimneys are susceptible to water damage.

Chimney structures are highly exposed to the elements and freeze/thaw conditions. The GOOD NEWS is water damage can be prevented. At Owens Chimney Systems, we use Chimney Saver Water Repellents™. This product comes with a 10-year warranty and has been used by chimney professionals for over 20 years. The active ingredients in Chimney Saver Water Repellents™ will significantly reduce water penetration into the masonry by 99.9 percent and is also 100 percent permeable, which means it won’t trap water vapors.

Why Permeability Matters

Permeability is also important because there is a percentage of smoke that moves through the brick to reach the outside. These are the smallest particles and important to expel through the system because it’s these small particles that can be easily breathed in. If you use a waterproofing material that blocks these pores of the brick, those small particles can flow back down the flue and out into your home through other cracks and gaps that are ever so small.

Knowing the correct materials and installation techniques will not only give you peace of mind that your chimney and family are protected but also comes with some very good guarantees. Contact us today to find out more.
