Price factors that will impact cost

Other factors that will influence your total expenditure for the project will include:

Cost of mold testing – Before any remediation process, most experts opt to conduct mold tests to confirm the type of mold in your bathroom. This information then guides them on how to deal with it. You can spend between $300 to $900 extra on this.

Hiring pros or DIY – Hiring experts for the remediation project is usually more expensive than doing it as a DIY. If you know your way around mold remediation, you can significantly cut down your costs.

Cause of the mold – If the mold infestation was caused by a leaking tap, roof, or poor insulation, you’ll spend a lot more on repairs.

Damages and restoration – Replacing the surface structures that the mold may have compromised obviously increase your costs.

Home insurance – While most home insurances don’t cover mold remediation, if you live in an area that’s prone to flooding, you can easily find insurance that covers at least a part of the remediation costs. This helps bring the prices down.

Types of bathroom mold

As you probably know, there are over 300,000 types of molds in the environment. Of these types, there are several molds that are fairly common in the bathroom. This includes the Aspergillus, Penicillium, Cladosporium, and black mold.

They mainly appear dark grey, green, blue, and sometimes brown making them quite easy to distinguish. The Aspergillus mold is the most likely to appear in your bathroom.

If you don’t spot these stains, other common molds you’ll find include:

Pink bathroom mold

When cleaning your bathroom, you might also come across some pink fuzzy patches and stains on the walls. These are known as the pink bathroom mold.

Despite their name, pink molds aren’t actual mold. They’re, in fact, a type of water-borne bacteria known as Serratia Marcescens, which can also appear within red-pigments, or orange.

The good thing about them is that they’re easy to spot and clean.

Black bathroom mold

Another common mold is the black mold. Known by many to be a dangerous and infectious mold, you have to be careful when dealing with it. It appears as a green-black patch that’s common under the showers, sinks, and bathtubs.

Dealing with this mold can be harder and more costly since you might need to spend extra cash on mold testing to ascertain the mold type.

Removing mold from showers

Mold under your shower appears like dark or greenish patches depending on the type of mold. Once you’re sure which type of mold it is, here are some steps you can try to remove the mold:

Step 1: Gather your supplies

Find all the chemicals and tools you’ll need for the job. This may include bleach, white vinegar, a spray bottle, and a course-pad brush. You’ll also need some protective gear such as a face mask, gloves, and eye protection gear since the chemicals you’re using might be toxic.

Step 2: Mix bleach with water and spray

Take some bleach and mix it in water to form a solution. Put the bleach solution into a spray bottle, then spray all the affected areas on the shower. Leave the solution on the moldy surface for about half an hour, and scrub it out using your coarse brush. Use warm water to rinse it. If you choose to use vinegar, the steps are still the same.

Step 3: Use a dry towel to dry cleaned areas

Find a dry towel or piece of cloth and use it to dry the clean areas.

How to remove black mold from shower grout

Your bathroom tile grout is usually the most mold-infested area in your bathroom. There are different ways you can address the situation, e.g., you can use bleach, vinegar, sodium peroxide, and even salt.

Using baking soda

Step 1: Assemble your supplies

To successfully complete the job, you’ll need baking soda, a spray can, cloth, and a brush or toothpaste. You should also always ensure that you have your protective gear on.

Step 2: Mix baking soda and water, then spray

Now mix your baking soda with water and then spray it on the infested areas using a spray bottle. Next, wait for around 30 minutes, then rinse the surfaces with warm water. If the grout is very dirty, you can wait for an hour or two before rinsing.

Alternative: Use baking soda paste

Instead of making a baking soda solution, you can also make a paste from the baking soda and apply it to the moldy grouts. Let it sit for about 10 minutes, then scrub the paste with a soft brush. Finally, rinse with water and repeat the process until the grout is clean.

Using Vinegar

Step 1: Protect yourself

Ensure you have your protective gear on (gloves, face mask, and eye protection gear).

Step 2: Mix and spray the vinegar solution

Mix equal amounts of the white vinegar with water in a spray bottle, then give it around half an hour to settle on the infected surface, then gently scrub it. Your last step will be rinsing the surface and repeating it until it’s clean.

Using Bleach

Step 1: Get your supplies

Confirm you have all the requisite tools to start cleaning your bathroom grout. Ensure you have a bleach (chlorine), gloves, spray bottle, face mask, a brush, and toothbrush.

Step 2: Mix bleach and spray it

Mix the bleach and water in a 1:4 ratio, then use a spray bottle to spread the solution to all the mold-affected areas. Wait for 30 minutes, then use a brush to scrub vigorously and rinse with cold water. Repeat the processes for the best results.

Alternative: Scrub bleach directly

Instead of mixing your bleach with water, you can also scrub bleach directly on the grout using an old toothbrush. Allow the bleach to settle on the grout for around 30 minutes, then rinse it with warm water.

Keep in mind: Using bleach can cause fading and discoloration of your colored tiles.

Use Hydrogen Peroxide

Step 1: Get your supplies

You’ll need to have hydrogen peroxide, baking soda, white flour, and protective gear for yourself like gloves, respiratory mask, and eye protection.

Step 2: Make a Hydrogen peroxide paste

Start by mixing the hydrogen peroxide with white flour until it becomes a paste. Apply that paste to the moldy grout in your bathroom and let it sit overnight, then rinse it with cold water.

Alternative: Use hydrogen peroxide with baking soda

Make a baking soda paste (as explained above), then apply it over the moldy grout. Next, pour the hydrogen peroxide paste over the baking soda paste until it starts fizzing. Now use a coarse brush to scrub the grout and rinse it with water. Repeat the process for best results.

Removing black mold from bathroom silicon

There are two main ways to remove mold from the bathroom silicone; Using vinegar and baking soda and using bleach.

Using vinegar and baking soda

Step 1: Gather your tools

You’ll need some white vinegar, bleach, baking soda, damp rag, coarse-bristle brush, wet sponge, and protective gear.

Step 2: Create a Vinegar and baking soda paste

Mix vinegar and baking soda in a 1:3 ratio, then rub the paste onto the silicone sealant with a thick layer and let it settle for around 5 minutes.

Step 3: Scrub and rinse

Use your course-bristled brush to scrub over the paste, then rinse the spot with cold water and a wet sponge. Repeat this until there’s no remaining mold.

Using bleach

Step 1: Mix bleach with water

Mix bleach and water in a 1:2 ratio, then apply or spray it to your silicone sealant and leave it to evaporate.

Step 2: Clean and Rinse

Use a wet cloth or sponge and cold water to clean and rinse the sealant, then use a dry cloth to dry the silicone sealant.

FAQ's

Yes! According to the Centre for Disease Control (CDC), every type of mold is dangerous for your health – even bathroom mold. With high infestation rates, these molds can result in allergic reactions like nausea, wheezing, coughing, and itchy eyes.

Bathroom mold can also increase the chances of infection among people with severe breathing problems.

Yes! As aforementioned, living in a house with bathroom molds results in allergic reactions such as nasal congestion, coughing, skin rashes, sneezing, and running nose, among other symptoms.

People with lower immunity and respiratory disease might also experience increased infection rates.

Not all of it! Bleach has been in use for many years to kill mold from homes. However, most manufacturers hide the fact that bleach isn’t as effective at killing mold as they advertise.

Bleach can only kill the mold growing on the surface of different materials. Therefore, if mold eats its way through a porous material like wood and concrete, bleach will only kill the surface molds.

White vinegar, on the other hand, has proven to be very effective at killing mold compared to bleach. It can access spores hidden in the porous surfaces and kill mold from their roots.

Yes! Fans can be really helpful tools for improving ventilation in your bathroom. It ensures that moisture doesn’t remain stagnant in the bathroom, providing damp surfaces for molds to grow on.

Nonetheless, having a bathroom fan can also do more harm than good. For instance, if not correctly installed, the fan will drive the bathroom moisture to other parts of the home.

This means more expenses to remove mold from the house. Moreover, the fans will only be effective if the person in the bathroom has switched it on. If anyone forgets, it could attract more mold growth.

However, if you don’t have a bathroom fan, always ensure the window is open when you’re taking a shower, and you’ll be okay.
