Protect Your Chimney & Prevent Leaks!

When it comes to keeping water out of your masonry chimney, prevention is better and far cheaper than undertaking repairs necessitated by water damage. Masonry chimneys are extraordinarily vulnerable to the ravages of rainwater, both because chimneys project above the roofline and because brick and mortar are porous. Luckily, you can have your masonry chimney professionally waterproofed with a formula that’s been proven to reduce water penetration into masonry by 99.9 percent, while still allowing your chimney to breathe. If your chimney is riddled with water leaks, liner damage, freeze/thaw damage, or efflorescence, ChimneySaver can help put a stop to the damage.

What Is ChimneySaver?

ChimneySaver water repellent

ChimneySaver’s waterproofing products let Mother Nature know she is not invited into your chimney. Unlike typical concrete sealants that can accelerate damage to your chimney by trapping water vapors inside, ChimneySaver is specially formulated to form a semi-permeable membrane that allows your chimney’s brickwork to breathe.

ChimneySaver contains patented siloxanes small enough to penetrate most masonry pores up to ¼” or more. These siloxanes form a strong bond with the silica in masonry and concrete. Because of this bonding process, one application of ChimneySaver provides up to ten times the water repellent protection of typical sealers.

This 100% vapor-permeable water repellent penetrates and lines the brick’s microscopic masonry pores, keeping new water from penetrating while allowing any water that’s already trapped within the brickwork to escape. This is important because moisture from a variety of sources is always present in masonry and concrete. If these vapors can’t escape, they will likely contribute to brick scaling, spalling, and freeze/thaw damage.

ChimneySaver’s 10 -Year Limited Warranty

Saver Systems warrants that ChimneySaver water repellent will exhibit a water repellent effect for 10 years from the date of application if applied according to label instructions and if minimum application requirements are met. Our chimney technicians will apply ChimneySaver so that you can enjoy the full life of its warranty.

Note, however, that no water repellent is a substitute for good construction and workmanship. The first step in preventing water damage is to make necessary repairs as needed by installing a chimney cap and repairing structural cracks, damaged crowns, flashing, deteriorated bricks, and mortar joints. The second step is to protect porous masonry from further water penetration by applying ChimneySaver Water Repellent. At A to Z Chimney Services we are trained to handle all of these repairs and precautions.

Dear A to Z,

The gentleman you sent to my home to clean my dryer vent was great! He arrived on time and was very careful about cleanliness. Also, he was very helpful and low pressure when I asked him to give me an estimate on Sun Screens for my windows. I’ll definitely be doing business with you in the future!
