It rained and your chimney is leaking. You know you need to have it repaired, but you just haven’t gotten around to it. However, your leaky chimney could be the start of an even bigger problem…chimney mold. Many homeowners often let this go before they realize it is beginning to harm their home. It is important to know the basics about your chimney, what to watch for, and who to call when you think you have a problem. The professionals at Ace Chimney Sweeps can perform a sweep and inspection, as well as many other tasks to make sure you and your family are safe.
What is chimney mold?
Chimney mold is the same idea as you would have anywhere else in your home, only in a different texture or color. If the old is left on your chimney long enough, it will begin to soak into your foundation. Since mold can form in as little as 24 to 48 hours, it is important that you have a trained professional come check out the unit quickly. They will also check when you have your annual inspection.
How do I get rid of my chimney mold?
To begin to remove the mold, you have to first understand where it is coming from. Start by looking at any area that water can collect, usually where flue precipitation goes, damaged flashing, or any cracks that may be in the structure. One way to check for these places is by doing a controlled water test. These should always be done on dry days and in small spots at a time to closely examine where the water enters. If the area is smaller than a 3-foot square, you can remove it on your own. If this is something you do not have experience with, it is still recommended that you call a professional. It is difficult to remove and can be hazardous to your health.
How can I prevent mold from growing in my chimney in the future?
There is no way to prevent mold from ever growing on your chimney. One way to lessen the chance is to have your chimney waterproofed. Technicians will arrive on a dry morning to apply the water-resistant sealant, and will also see if you need a second coat as this is common in some wet environments. Each coat will take at least six hours to dry, so check the forecast ahead.
The Chimney Safety Institute of America (CSIA) also recommends having a chimney cap installed. These are inexpensive and productive ways to not only keep rain out, but animals and debris as well.
