4 Plumbing Issues to Watch out for That Cause Mold & Mildew – What to Know

Mold and mildew are detrimental to any household. It gives off a nasty smell, and its presence makes your house look dirty and unpresentable. If you noticed that your home is suffering from what seems to be a fast-spreading fungus, then it’s time to get those water lines checked. Usually, it’s your plumbing system that’s the primary culprit behind mold and mildew infestations.

Here are some of the plumbing issues that cause mold and mildew in your home:

1. Concealed Leaks

The worst leaks are the ones that you don’t know are there! These types of leaks are the ones that usually cause mold and mildew, especially leaks inside the ceilings and walls, as these are breeding ground for mold.

How can you spot these leaks? Check for a sudden rise in your water bills, be on the lookout for discolored spots on the walls and ceilings, and observe your water heating. Often, if there’s a leak, water heating will turn on and off at random intervals. Also, a good preventive measure to check for leaks is to have a routine leak detection conducted every once in a while.

2. Standing Water

One significant cause of mold is standing water. If you leave too much standing water out in your bathroom, then don’t be surprised if an accumulation of mold starts to show, despite you continually wiping down the shower or your tub.

A slow drain often causes standing water in the shower or bathtub, which is a common problem for homeowners. If you notice that your shower area or tub takes too long to dry out completely, then you might have issues with your drain. Call a plumber right away to have it fixed.

3. Sink Leaks

The leaks under your sinks may be hard to distinguish because these areas are also where you store some of your cleaning products and materials. Watch out for an odd smell below your sink or keep an eye on any water spillage. If you find out that there’s a leak, clear out the area and call your plumber to have it fixed.

4. Flooding

Any house can suffer flood damage due to a plumbing disaster. Don’t consider yourself exempted from, especially if you have no regular plumbing maintenance, as you will likely experience a broken pipe at least once in your lifetime.

Most homeowners would merely clean the mess up, especially if it’s not obstructive, only to find out a few weeks later that it’s a mold infestation causing the damage. In the event of flooding, no matter how minor it looks, call a plumbing company right away to have the issue diagnosed and resolved.


The last thing you want is a house filled with mold. However, regardless of how clean your home is, there will always be invisible mold spores out there and disinfectants can only do so much. While it’s impossible to eliminate the presence of mild microscopic spores, you can definitely prevent a full-blown mold infestation from happening in your home through preventative measures.

Keep in mind that much of the mold and mildew issues come from your plumbing system. As such, you need to have your water lines checked regularly and routine maintenance performed on your pipe system every so often.
