Dealing with mold in your bathroom

Posted by Luke Henning on Fri, Mar 16, 2018


San Diego has a big problem in that later half of spring and in the summer...mold. Especially mold in bathrooms. You might notice mold and mildew growing in your bathroom, particularly on the caulk used on your bathtub or shower. This is an even bigger problem for poorly ventilated areas, like in small apartments. 

Why Does Mold and Mildew Grow on the Caulk?

Mold grows in humid areas where the spores can find sufficient moisture. The spores that reside in homes find themselves in the caulking of showers and bathtubs. They doe this because caulk is porous and can retain moisture. Poor ventilated bathrooms allow them to multiply freely in the dark and humid atmosphere.

Removing Mold from Caulk

You can find many home remedies online to fighting the mold that plagues the caulk in your bathroom. From bleach soaked cotton balls to spray bottles with a bleach and water solution. We always recommend calling a professional service that focuses on mold remediation. The main reason we recommend going professional over doing it yourself is the mold that is growing on you caulk might not be all of it. A lot of times the mold is not only growing on the caulk, but growing IN it and UNDER it! If you attempt to remove the mold yourself, and find that it is not easily removed, it is most likely growing inside or under the caulk. If you find this is the case, please call a mold removal specialist.

Mold Under or Within the Caulk

If the mold is under or within the caulk, the caulk needs to be removed and replaced. After the removal of the caulk, the area needs to be sanitized before any caulk can be placed. If left unchecked, this mold can grow deep within the bathroom and will cause more damage, and therefore be far more costly. This can all be done yourself, but for best results, call a mold removal service. A professional will be able to properly sanitize to prevent this problem from reoccurring. They will also replace the caulk with more specific bathroom caulk, because not all caulk is created equal and using the right tools is a big step in the right direction.

Preventing Mold in Your Bathroom

The best advice to keeping mold out of your bathroom is constant surveillance, cleaning, and ventilation. In the hot summers of beautiful San Diego, ventilation is key. So many times after a shower we forgot to turn on the fan and air out our bathroom, we just turn the lights on and leave it be. It is really important in the upcoming months to remember to air out your bathroom after a shower so you don't end up fighting a big mold battle in the future. Always be a look out for black spots, mildew, and possible mold growing in your shower. Anytime you use the bathroom, just have a mental note to give it a quick look over. If you do see any mold problems in the early stages, clean it up! When you do, please always remember to use the proper gear when handling any chemical based cleaning supplies. Wearing googles, gloves, and a mask is strongly encouraged!
