How To Identify Mold?

Before checking on the molds behind the shower tiles, you need to be sure of their existence. Fortunately, there are some symptoms by which you can identify where your bathroom has growing molds or not.

Nasty Smell

A terrible odor is the first symptom of having mold. You will notice a wood-rotting smell which is not very pleasant. It’s because of the decomposition of mold spores. Also, this pungent smell may cause health issues.

Muddy Appearance on Floor

When your bathroom has molds under the tiles, you will notice the floor becoming slimy and damp. You’ll also see some black circles on the bathroom floor.

Ants Get Attracted

We all know that ants want to build their nest inside the moist woods. So, when you notice ants in your bathroom, try to locate their nest whether they are under the floor or not.

If you find the nest, it means the molds are decomposing the floor woods.

Damaged Walls

If you see crumbling plaster, discolor or cracked tiles, disassemble tiles, the most apparent reason is moisture, which means growing molds.

Suspicious Floor

It means your floor may feel spongy or unstable if there are molds behind them. Therefore, you need to check for molds immediately.

Check For Mold Behind the Shower

As you have learned how to identify mold, it’s time to check the molds behind your shower tiles and see how much they have spread under your bathroom floor. 

So, let’s dig into the detailed process of checking mold and see which one is suitable for you.

Use Optic Camera

A fiber-optic camera is very handy to check on the molds behind your bathroom tiles. 

You will need to drill a hole in the drywall of your bathroom where you are suspicious of having mold. Then, you can just insert the small wire that contains the camera (or you can say the whole wire is the camera). Now, you can monitor if any molds are growing in your bathroom or not.

However, note that the fiber optic camera covers a tiny area, and they may not be helpful with the view when there is dirt on the lens. On top of that, it can’t move in very congested places. So, it can’t follow the mold branches till the end of the line.

Use Some Home Testing Kit

There are some mold testing kits for homes available in the market. You can use them in your bathroom for a quick test.

First, you need to dig or cut a hole in the bathroom wall. A screwdriver or any sharp tool is helpful to dig a small hole. Then put the home testing kit and check whether any mold is growing behind the wall or not. These kits can also show you which type of mold is attacking your tiles.

However, if the machine malfunctions, it won’t show you proper results.

Monitor the Ductwork

You might have an HVAC unit in our bathroom to control the heating. Growing mold behind the wall is one of the main reasons for a malfunctioning HVAC unit.

So, monitor your HVAC unit regularly and consider it as a mold checking test. Well, it’s because condensed moisture makes the drywall wet by creating water inside the ducts. And it’s the best condition for molds to thrive. Therefore, if you check your HVAC regularly, it will act as a test of checking mold behind your bathroom wall.

There are some other reasons for a malfunctioning HVAC. So, don’t just jump into finding mold before checking the ducts or monitoring other symptoms of having molds.
