Anyone who has a chimney featured in their living space knows that their is always the risk of having a leak. While there can be many reasons for the leak, one of the most certain things about it is that is can be extremely costly to fix. While the high cost of fixing the leak may deter people from fixing it as soon as possible, that is not a wise decision at all. The longer the leak goes unattended the worse the situation can escalate. Problems such as water damage, gas hazards, mold growth, and insect infiltration can all stem from the leak.
One of the several reasons for a leak in the chimney can be due to a missing or damaged chimney cap. Many may wonder what a chimney cap is or its purpose. The chimney cap is what helps to keep animals and debris from entering into the chimney. This also assists with keeping out rain and other weather related elements. It is wise to get the chimney cap checked out first for damage, because it is much cheaper to replace the chimney cap then some of the other repairs of a leaky chimney.
A cracked chimney crown may also be causing the leaking in the chimney. As time goes on the chimney crown shrinks, cracks, and can cause potential leaks due to its age. The size of the crack plays a big part in determining whether or not the crack can be sealed or patched. However, if there is severe damage that cannot be patched or sealed it may call for the masonry to be completely redone altogether.
In other cases sometimes a faulty chimney liner can be to blame for the leaking in the chimney. Over time, gas fumes can build up inside the chimney. If the chimney liner doesn’t fit properly or has corroded and produced holes the gas combustion fumes can produce moisture buildup. This moisture can then soak into the bricks since the chimney liner is not protecting it and produce the unwanted leaking.
Most chimney leaks tend to come during the cold and wet parts of the year. It is best to get your chimney checked out during this time frame in order to protect it from any potential further damage.
