Three Signs Your Chimney Has A Moisture Related Problem

Diagnosing a problem with a chimney if you aren't a professional isn't exactly easy. However, as a homeowner, recognizing the signs that there might be a problem isn't very hard. This is especially the case when it comes to a moisture related problem. Being able to notice these signs quickly can help you get the necessary repairs and mitigate further damage. Here are just some of the indications that you might have a moisture related problem taking place within your chimney.


With a properly functioning chimney, you shouldn't see rust anywhere. Signs of rust development along a damper or firebox is often a sign of a problem with your chimney. In short, the presence of rust simply means that moisture is likely getting in through the damper. A broken or worn seal are often to blame.

However, an issue in the flue tiles is also possible, such as cracking. Addressing this problem is important because the rust will only continue to spread and increase the chance of you having to deal with other moisture related problems in your home.  

Mortar Joint Deterioration

If you can clearly see that the chimney's mortar joints are deteriorating, make sure you are addressing this problem promptly. When moisture is not properly being ventilated through the chimney, it ends up settling within the mortar. The reason this is so critical is that as the joints deteriorate, their structural integrity also wears away.

This factor can increase the risk of the bricks caving in and falling down. The risk for this is increased during the winter months when the freezing temperatures can allow this moisture to freeze between the bricks.

Wallpaper Damage

If you have wallpaper installed anywhere near your chimney, any damage might actually be the result of a chimney concern. When a chimney is not functioning correctly, excessive amounts of moisture can enter inside. Once this happens, the moisture gets behind the wallpaper, loosens the adhesive and causes air bubbles to form on the surface.

If the wallpaper was in good condition and this problem suddenly begins in this isolated area, it's time to have the chimney inspected. If you fail to address the issue, the moisture behind the wallpaper can introduce mold growth that can be structurally damaging and harming to your health.

Moisture related chimney problems can range from failed seals to incorrect ventilation. However, no matter the source, being able to recognize the signs of a problem is most important.
