Recognize the Staining

Stains on your chimney? Then you need chimney services. The hue of the chimney stain indicates the cause. If your chimney has white, black, red, green, or brown stains, you require chimney services.

Black Stains
One of the most prevalent kinds of stains is a stain that is black in color and is scattered throughout both the inside and exterior of the chimney. The majority of black stains are caused by a buildup of soot, which indicates that the chimney has not been properly cleaned and maintained on a regular basis.

On the other hand, if black stains are observed on the exterior of the chimney, this may be an indication of a more significant problem. These dark black and dark brown stains are the result of too much creosote being present. Creosote, on the other hand, is produced when unseasoned wood is burned in flames that are kept at low temperatures and smolder.

Creosote can also be caused by a flue that is improperly sized for the firebox and by not having your chimney professionally swept when there is a 1/8″ of sooty buildup, as recommended by the Chimney Safety Institute of America. Both of these factors can lead to a buildup of creosote in your chimney (CSIA).

Creosote accumulation and black stains on the interior and outside of your home may cause you concern for the following reason: chimney fires. Fires that start in chimneys tend to start unexpectedly and spread rapidly, soon consuming the entire house. It is not normal for gas-burning fireplaces to leave soot marks on the outside of the chimney, and if this does happen, it may indicate a dangerous carbon monoxide leak.

Dark Green Stains
On the outside of the chimney, a discoloration that looks like a dark green is often visible. It’s also possible that you saw these splotches of a dark green color on your roof. These stains are formed by the growth of algae, and they appear as streak-like patterns. People sometimes mistake them for signs of degradation, but the truth is that they are generated by algae.

Because of the dark color of this stain, it may be difficult to detect the difference between soot markings and algae development; thus, it is recommended that a professional examination be carried out in order to make an accurate distinction.

When there is a steady flow of water present for the algae to feed off of, then the algae will begin to grow. This may occur if the crown of the chimney does not have an overhang, if water has found a place on the chimney where it may pool and gather, or if there is a spot on the chimney that is prone to water run-off.

If you let the algae growth continue, it may cause damage to the brick and mortar that make up the construction of your chimney; nevertheless, the growth itself is not damaging to the workings of your chimney.

Red Stains
On the external surfaces of chimneys that are prefabricated or constructed of metal, stains with a reddish tint can be seen. The corrosion of the metal that makes up the chimney chase cover has caused the red stains to appear. When a piece of metal is exposed to water, rust will develop, and red spots will start to appear on the surface.

If there are stains of a reddish color on the exterior of your chimney, it is possible that there is a leak in the chase cover that is allowing water to enter the chimney and the fireplace. It is imperative that you promptly replace the corroded chimney chase cover, as water damage is extremely detrimental, not just to chimneys but to any property.

White Stains
And last but not least, there are the white spots. The white mineral salt that is left behind as water evaporates is known as efflorescence, and it appears in the form of this powdery discolouration. Rain, ground water, sprinklers, and run-off are some of the many various types of water sources that can leave efflorescence behind. Since your chimney is continuously being exposed to water and the outside elements, it is normal to observe efflorescence on the exterior of your chimney.

Efflorescence on the inside of anything, on the other hand, is not a healthy indication. If there are white stains on the interior of your chimney, this indicates that water has made its way inside, which it most certainly should not be doing. Your chimney has a leak somewhere on the interior, and you have to find and fix it as soon as possible to prevent more severe water damage from occurring.
