Water is necessary substances that all needed, in fact, it is one of nature’s building blocks. At the same time, water can also have the power to wreak havoc on unprotected chimneys. This can lead to accelerated structural deterioration and eventually develop into a safety hazard. Even a small leak will grow into a bigger problem. So preventing chimney leaks during the spring rainy season should be a top priority of every homeowner. Herewith steps need to be taken to avoid chimney leaks, especially during spring rainy season.
Steps to Preventing Chimney
1. Inspect masonry for damage
Since water leaks can occur practically anywhere around the chimney. They are frequently difficult to spot, it is vital to inspect the masonry for damage. Although stone chimneys are less prone to water damage, the mortar holding them in place can soften when exposed to water. It is recommended to repair any cracked, missing or spalling bricks and deteriorating mortar joints as soon as possible. Also, be sure to inspect the chimney crown and the flashing (a thin metal strip between the roof and chimney).
2. Install a Chimney Cap
Ever notice water in the firebox or white smoke when putting light the fireplace? This is a common problem that is likely the result of a wet firebox from an uncapped or damaged chimney cap. A chimney or rain cap affixes to the crown. The function of it is like an umbrella to assist prevents chimney leaks and debris from clogging the flue.
3. Replace the damper
The damper is a metal or aluminum cover inside the flue that seals the outside elements and protects the fireplace when it’s not in use. Water, debris and normal wear and tear can cause rusting, warping and other damages that can significantly decrease its usefulness. To prevent leaks, this critical chimney part should be inspected periodically and repaired or replaced when necessary.
4. Apply a waterproof coating
Like a sponge, masonry like bricks and mortar are porous materials that soak up water. And after a few rainy seasons, the bricks and mortar start to soften causing loosened masonry to deteriorate and even fall from the chimney. An effective way to prevent chimney leaks is to apply a waterproof coating specially formulated for masonry. Be sure to repair any damaged masonry or mortar joints before its application for best and maximum results. However, waterproofing will need to be re-applied every 5 to 10 years to maintain its effectiveness.
5. Annual Maintenance
An annual maintenance and inspection by a certified chimney sweep is the best way to prevent chimney leaks is with. Occasionally, homeowners are able to detect water in the chimney, however often they are having trouble finding the source. Water can go through tiny cracks and crevices that are difficult to identify with the naked eye. Having chimney specialists which are trained experts who carry sophisticated tools, allows them to spot and avoid chimney leaks wherever they may be occurring.
