Chimney Waterproofing

Water penetration is the number one cause of chimney damage. The midwestern climate is tough on chimneys. Rain, snow and freezing temperatures can wreak havoc on a masonry chimney, causing cracks in the mortar and structural damage. All masonry chimneys are vulnerable to water damage. In fact, moisture is always present in a masonry chimney. For this reason, we recommend treating your chimney with a water repellent.

ChimneySaver® Water Repellent

Fluesbrothers uses an excellent product — ChimneySaver® water repellent. ChimneySaver® is specifically designed to protect chimney exteriors from harsh weather conditions and is guaranteed to last for 10 years. Just one application of ChimneySaver® will provide about 10 times the water repellant protection of other sealers. This product is a 100% vapor-permeable waterproofing agent that will protect your chimney from the damaging effects of water, including brick flaking, cracks and gaps in mortar.

Some of the benefits of ChimneySaver® include:

  • Minimizes deterioration of brick masonry
  • Blocks water from penetrating into brick masonry
  • Protects homeowners from expensive masonry repairs

Waterproofing your chimney is an investment in the long-term protection of your property. This investment will hopefully save you hundreds or even thousands of dollars down the road.

It is especially important to treat your chimney with a water repellent when a new liner has been installed. If you have recently installed a new chimney liner, now is the time to treat your chimney with ChimneySaver®. Without a water repellent treatment, your chimney will just continue to break down around the new liner and will ultimately have to be rebuilt.

While waterproofing your chimney is a good idea, nothing can take the place of good construction. The Fluesbrothers will inspect your chimney and let you know if there is a problem with the structure that may be causing leaks. Click here to schedule an appointment online.
