If your chimney is left exposed to elements with no treatment, it will be susceptible to deterioration and may need masonry repairs. You should have this problem address by a professional chimney sweep before any serious damage can occur.
Here are some of the advantages of using a masonry waterproofing solution:
- Minimizes/eliminates/retards brick masonry deterioration.
- Prevents water penetration & absorption from saturating brick masonry.
- Preserves & maintains existing & restored brick masonry.
- Eliminates future brick chimney repair costs.
Chimney need protections from water to prevent costly damage to your stack and other components from above the roofline. There should plan to completely protect your chimney as much as possible. The program should include repairing the crown with Crown Saver, along with a treatment of Chimney Saver water Repellant. Your flue tiles should have a chimney caps to stop any water from reaching you chimney’s interior. Also pay close attention to your chimney’s flashing around the base of your chimney. Make sure that all of the visible points of water entry have been repaired.
SaverSystems, the manufacturer of ChimneySaver products, warrants that CrownSaver, when used to coat or repair masonry chimney crowns, will remain intact and in place for 10 years from the date of application to an residential chimney crown according to label instructions when properly applied by a professional contractor. This warranty does not cover spalling, abrading, faulty construction and/or other defects which might erode coated surfaces.
The crown of the chimney can sometimes become cracked and allows water to flow into the chimney. The Fireplace Doctor can cover the crown with an elastomeric substance that looks like a rubberized cement. If the cracks are extensive a new crown can be formed.
Chimney CrownSaver is a flexible waterproof sealant that is applied over the entire chimney crown. A professionally installed CrownCoat application stops further water intrusion through the crown.
It’s specifically formulated to withstand the severe weather and thermal stress to which chimneys are exposed. It is flexible, forms a continuous, seamless coating with a smooth flat finish. Flexible Crown is designed for use over exterior masonry, stucco, poured concrete, precast concrete, and concrete block.
According to the Brick Industry Association, chimneys require special attention and maintenance to prevent costly damage caused by water penetration. Because chimneys project above the roof line, they are vulnerable to the elements. Nearly every chimney you encounter has signs of water damage! The first step is to determine the cause and then find the best corrective measures. ChimneySaver, the first product developed specifically for chimneys, has been used successfully by leading chimney professionals for nearly 20 years. It reduces water penetration into the masonry by 99.9%, according to ASTM tests conducted at the University of Wyoming.
It’s also 100% vapor permeable, which means it won’t trap water vapors that may pass through the bricks when the chimney is in use, unlike other products found in most hardware or home improvement stores. Those products when applied to a masonry chimney can actually slow down water vapors as they pass through the chimney leading to water damage.
Moisture from a variety of sources is always present in masonry and concrete. Sealers and silicone coatings form a water resistant surface film which trap water vapors inside. If these vapors cannot escape, they will contribute to spalling, scaling, deterioration, and freeze-thaw damage. ChimneySaver is 100% vapor permeable – a non film-forming water repellent that penetrates and lines masonry pores.
