6 Ways to Prevent Mold Growth in Your chimney

Mold grows in damp, dark, secluded areas. Unfortunately, without proper maintenance, your chimney can be one of those areas.  Mold can pose many health concerns for homeowners. Mold growth has been linked to asthma and allergies, and more serious conditions like respiratory infections and lung disease. Health issues aside, mold can cause structural damage to your chimney, which could be costly to repair! Fortunately, mold can be easily prevented by following a few best practices for chimney maintenance. Here are 5 simple ways to prevent mold growth in your chimney. 

1. Have a professional chimney inspection every year

If you have been noticing moisture or wetness in your fireplace, it would be a good idea to call a professional chimney service company for an inspection. The professionals can take a look at the area of concern and give you advice on how to fix the problem before moisture becomes more of an issue. 

Chimney experts will first inspect your chimney for any structural damage that needs to be addressed before continuing. They will then use tools such as a video camera or moisture meter to see if there is any water seeping into the masonry. If they find any cracks, leaks, or holes, they can repair them before they become a more serious issue. 

According to the CSIA, it’s recommended that you have your chimney inspected once per year. This way, if there are any issues with moisture or mold growth, you can get them taken care of right away.

2. Clean your chimney regularly to remove any build-up of soot, dust, and debris.

Creosote, soot, and debris in your chimney can lead to moisture build-up and mold growth. If you do not clean your chimney regularly, you might have a fire hazard and health concerns such as allergies, asthma, and more serious conditions. The best way to prevent mold from growing is to sweep the inside of your chimney at least once a year, according to the CSIA recommendations. You can use a brush attachment on your vacuum or a chimney cleaning kit. Make sure to get all of the corners, crevices, and inner walls of the structure. 

If you are not comfortable sweeping your own chimney, or if it has been a while since you have done so, please consider hiring a professional chimney sweep service company to clean your chimney for you during this process so that they can ensure it is done properly. 

3. Check your chimney for any cracks or holes to make sure there are no leaks.

If any moisture or water is entering your chimney, it will start to deteriorate the mortar and other areas of the structure. This could lead to a cracked structure which can cause pieces to fall down inside your fireplace and crack your fireplace glass. Water damage also increases the risk of mold growth which can affect your home’s air quality. 

The best way to prevent this from happening is simply by checking your chimney for any cracks or holes before it becomes a serious problem. The best way to avoid this problem is to check your chimney regularly for any cracks or holes that might let in moisture. A DIY approach might do the trick. However, you can also consider hiring a professional chimney service company. An experienced chimney technician will be able to spot any cracks or holes in your chimney before they become an issue.

4. Waterproof your brick and mortar

Make sure that your chimney service company uses brick and mortar that has been waterproofed.  Proper waterproofing is an essential part of preventing mold from growing. However, it is recommended first to have your chimney inspected for any structural damage before waterproofing. This is because sealing damaged brick in your chimney won’t prevent water from seeping through.

If you want to prevent mold from growing inside your chimney, there are a few things you can do. One of the best ways to do it is to prevent rain from entering your chimney by installing a chimney cap. A chimney cap is designed to keep the rain out of your fireplace and prevent moisture from entering it. This will reduce your chances of mold growth and make sure that rain doesn’t ruin the inside of your home.

Waterproofing and chimney caps are two of the best ways to prevent mold growth in your chimney. If water is not allowed to enter your fireplace, you will eliminate the possibility of mold growing inside your home. If you need help stopping mold from destroying your property, please don’t hesitate to call a professional chimney service company.

6. Keep your chimney well ventilated

One of the best ways to prevent mold growth in your chimney is to keep it well ventilated. If there is not enough ventilation, moisture will build up and create the perfect environment for mold to grow. 

There are a few things you can do to improve ventilation in your chimney. For example, you could check your chimney for any obstructions that may be blocking the airflow. You can also check the size of your fireplace. If your fireplace is too small, this could reduce the amount of air and make it more likely that moisture will build up. Keeping your flue liner free of creosote buildup is another way to improve ventilation. Creosote buildup can slow the rate that smoke exits that chimney.  

This list is not all-inclusive, and there are many other things you can do to improve the ventilation in your chimney. Your local chimney service company can provide you with more information.  

 If you have any more questions or concerns, feel free to contact your local chimney service company either by phone or in person. It may be tempting to go with a DIY approach. However, it is always advisable to hire a professional when it comes to cleaning and inspecting the inside of your fireplace so that they can spot any issues before they become an expensive problem later on.
