Waterproofing Your Chimney

Water damage plays a huge role in shortening the lifespan of a chimney and should be addressed before it is an issue. The quality that makes brick such a durable and excellent material for building fireplaces and chimneys is the same quality that makes it vulnerable to water damage. Brick is porous by nature which means it breathes. This porosity allows smoke and heat to escape, making brick very safe and durable under high temperatures. However, the porosity of brick also allows water to bleed in which can lead to corrosion, lime-leaching and cracks. Anytime water is allowed into the brick, the structural security of the chimney is compromised.

In addition to the corrosive nature of water, it also changes physical states as the temperatures change. When the temperature drops drastically and then warms back up, a cycle of freezing and thawing (constricting and swelling) can take place where the water has penetrated the brick. Over time, this process will lead to the complete crumbling of the penetrated brick. To prevent this from happening and threatening the structural safety of your chimney system, it is important that you have your chimney properly and professionally waterproofed.

What’s Involved In Waterproofing?

There are many waterproofing options out there, but it is important that you have a professional’s advice and application. Many sealers advertised as waterproofing products are actually silicone-based and coat the chimney with a waterproof layer. The problem with these sealers is that they not only keep water out, they keep air out and trap water vapor in. But, as you now know, it is vital that brick be allowed to breathe.

At White Glove, we know the role that porosity plays and only use vapor-permeable sealers such as Chimneysaver’s Solvent-Based Water Repellent. Unlike silicone sealers, ChimneySaver allows air and water vapor to enter and exit the brick while keeping water molecules (which are larger) out.

Chimneysaver’s water repellent products come with a ten-year warranty and promise the following qualities:

  • 100% vapor permeable
  • Matte finish
  • Prevention of efflorescence and staining
  • Prevention of mildew and fungus
  • Protection from the freeze/thaw cycle

"Dear Bob,
Thank you for your gracious handling of our complaint. By way of explanation, as I'm sure you & your staff were curious but were too polite to ask, I will offer this brief tale of the chicken in the duct. Turns out that this was the work of our obviously disgruntled & vindictive ex-renter who we evicted in October after 6 month of proceedings for lack of rent payment (not to mention the large marijuana growing operation had going on our property). We had 2 CA State Troopers supervising & escorting him off the property but he was allowed to return with the Management company employee to get his stuff out the following weekend. At that time he must have taken the store bought chicken & stuffed it down the vent as a final act of vengeance. As it turns out, this is the same creative mind that made headline news in your community (& world wide it turns out) for cooking & feeding the dog to his girlfriend (when you were first called we had no idea of what this character was capable of as his stunt with the dog was more recent). This is certainly "one for the books"! We are probably lucky it was JUST a chicken... I guess, considering this warped individual's history, it could have been worse!"
