⭐ Common Types Of Mold

At Ultimate Mold  Crew, we’re often called in to remove black mold in the bathroom – it’s one of the most common places that mold grows indoors, but many homeowners don’t understand why or know how they can make simple changes to their home and habits that can help reduce the likelihood it will grow.

Mold spores [Ref: Wikipedia.org] travel indoors on clothing, shopping bags, and even on pets. They also weave their way into a house through windows and leaky roofs. Once the invisible spores settle on a wet surface, they can begin to reproduce within 24 to 48 hours. Researchers have identified over 100,000 different strains of mold, but they all fall into one or more of three categories.

  • Allergenic: This means that they can trigger allergic reactions and asthma attacks in people with allergies and cause mild allergic symptoms in those without allergies.
  • Pathogens: These mold usually only cause symptoms in people with immune system disorders or in those who have or have suffered from a serious illness.
  • Toxigenic: These types of molds are the most dangerous and can cause serious health problems, even in healthy people.

Lets know more about some common types of mold [Ref: Wikipedia.org] or fungi seen in household properties in Toronto, GTA areas.

  • Aspergillus is commonly found on foods and in home air conditioning systems. It is common in many homes and is likely to grow on any wet surface, but is difficult to identify as there are over 180 strains of Aspergillus and many are different colors. Most strains of this allergenic mold are harmless, but a few can cause serious illness or lead to a fungal infection known as aspergillosis in people with weak immune systems. Since testing is the only way to determine if the type of mold in your home is Aspergillus, your best bet is to clean up all types of mold as soon as you spot them.
  • Cladosporium is typically a black or green “pepper like” substance that grows on the back of toilets, painted surfaces and fiberglass air ducts.
  • Fusarium – It thrives and spreads even in temperatures near zero. Fusarium strains can appear almost anywhere. Fusarium likes to grow in soft textiles, such as carpet, upholstery, wallpaper, and draperies, and it often appears as pinkish or reddish spots. Frequent cleaning with a vacuum equipped with a HEPA filter will reduce the risk of Fusarium settling in your home.
  • Penicillium – Strain of Penicillium mold is both allergenic and pathogenic. It produces spores that can trigger allergy-like symptoms such as sinusitis, difficulty breathing, and episodes of asthma. In people with immune system disorders, symptoms can be more severe and lead to chronic health problems. This bluish-green fluffy mold is often found in homes that have experienced flooding or other types of water damage, and it needs constant humidity to thrive. Once Penicillium has spread throughout the house, professional mold treatment is recommended.
  • Trichoderma – Small raised spots of white and olive-green mold growing in damp areas, such as near a leaky window or around a shower, can indicate Trichoderma mold. This type of allergenic mold grows quickly in damp places. Trichoderma in a home can cause coughing, sneezing, and bronchial infections.

Mold [Ref: cdc.gov] that appears to be orange or red in color is typically found outdoors, given its nature to thrive on decaying plants or moist wood. This type of mold,  can appear slimy, is harmless and should only be removed for aesthetic purposes.

There are many types of mold that look black, and not all “black mold” are as toxic as Stachybotrys.

Commonly referred to as “black mold” for its greenish-black color, Stachybotrys is a toxic mold that thrives in humid conditions and is most commonly found on cellulose-like materials, such as wood, drywall or even piles of leaves. wet. It starts with small black spots that get bigger and spread.

Stachybotrys is a dangerous mold that can cause a host of physical symptoms, including severe headaches, unexplained nosebleeds, upper respiratory discomfort, and fatigue. It could also cause bleeding in the lungs of infants. If a family member is showing symptoms and you are concerned your home may be infested with black mold, call our mold decontamination experts who can test for mold and determine the best way to get rid of it.


It is crucial to prevent the growth of mold at early stages to avoid any health issues and inconvenience and a mold remediation professional can easily do this. Lets talk about indoor mold growth at home and other important aspects of mold removal.

⭐ Mold growth in home

Knowing where indoor mold likes to grow in a home environment is an important part of any mold remediation process. If you always feel unwell in a particular room or floor of your home, that may be a good indication of nearby mold growth. But mold has its preferences, and there are a number of common places in your home that it likes to grow. Mold needs three important ingredients: water, dampness, a stable temperature, and an organic material it can feed and grow on. Those things can be found abundantly in our homes, which means that we frequently find:
  • Mold in Attic –  [Also read – What Is The Cost of Attic Mold Removal in Toronto ]
  • Mold in Bathrooms
  • Mold in Basements
  • Mold Around windows and doors
  • Mold in Cold Room/Cold Storage
  • Mold in your Crawlspaces
  • Mold in Kitchen
  • Mold in Bedroom
  • Drywall Mold
  • Plaster Mold
  • Ceiling Mold
  • Mold in Concrete
  • Mold in Foundation
  • Near sinks and drains
  • Behind appliances like washing machines and fridges
This list doesn’t mean that there isn’t mold growing elsewhere in your home, but it makes for a good starting place when it comes to visual mold inspection in toronto. For more detailed information check out our post on Mold in Home – Symptoms, Problems & Prevention

⭐ Mold health problems

Mold growth can be tricky to spot by the health problems it causes, because they can often resemble the common cold or flu, which makes it difficult to differentiate between the two during the winter months. Common reactions to mold spores include:

  • Sneezing
  • Itchy eyes
  • Nasal congestion
  • Headaches
  • Asthma

If you experience any symptoms like these, paying close attention can help you determine whether or not you may need a mold remediation in Toronto.

Do your symptoms disappear when you leave a particular room? When you go to work do they alleviate, and do they worsen when you return home?

Mold can easily grow out of sight behind walls or behind heavy furniture, making it difficult to see. The symptoms it causes may be the only sign that there’s a problem.

⭐ Causes Of Mold

As mentioned major factor responsible for bathroom mold is the level of humidity which increases to higher degree when you take shower. But is this the only cause? No.

There are many other causes associated as poor ventilation. As while showering the doors are usually closed. This raps all the moisture-laden steam produced because of hot shower. With almost negligible air flow during the shower, moisture attached itself to the celling and floor of the bathroom providing a gateway to mold growth.

  • Bathrooms are the wettest areas of the house, except the basement, perhaps. Even if you ventilate the bathroom the dampness penetrates to the sink, showers, even toilets giving way to the mold to grow.
  • Another cause of mold growth is, deteriorating caulk. As grout starts cracking, moist air finds its way easily to the cracks, sides and back of the tiles. Using paint as a source of food, and the darkness behind the tiles becomes the new home to moisture earlier and mold later.

⭐ Getting Rid Of Mold in your Bathroom?

The most obvious reason you may need to remove black mold in the bathroom is moisture and humidity. Naturally, because of bathing and showering, the bathroom is a place in your home with lots of opportunity for water and moisture to go where it isn’t welcome and to linger and cause trouble.

If wet surfaces or puddles aren’t dried out quickly, they can lead to mold growth – the same goes for rooms without adequate ventilation, since humid air can travel and settle in places that water usually doesn’t reach.

All this repeated moisture can help create the ideal conditions for mold growth in your bathroom. The main ingredient for mold growth is some sort of water – an organic material and stable temperature give both food and ideal growing conditions. As you can imagine, the bathroom is full of these three necessary ingredients, making it a prime location for mold growth.

Cleanliness is imperative but it doesn’t give you the guarantee that mold won’t grow in your bathroom. It’s obviously because of high humidity. As level of humidity is the only responsible factor for growth of mold in the bathroom so the best way to prevent the growth of mold in the bathroom is by controlling the level of humidity in the bathroom.

⭐ Common Spots For Bathroom Mold Inspection

If you need to remove black mold in the bathroom, there are a couple of places that it frequently occurs, and good reasons why those places are so commonly affected. Black mold often appears because of:
  • Blocked bathroom drains: Does your shower or sink drain slowly? Is it constantly clogged or create lingering puddles in the basin? If this sounds like your home, this standing or persistent water might be the reason there is mold growing in your bathroom. If you have a big problem with hair or other things blocking up the drain, there are inexpensive plastic and wire drain catchers that can help prevent things from making it in there. Chemical washes and other products available at home improvement stores can help dissolve detritus already in the drain, but they’re not the best for the environment – cleaning out the P or S trap under your sink can help, or having a professional plumber in to ensure there aren’t bigger problems can also make a big difference.
  • Excessive humidity: Do you have a fan in your bathroom? Make sure your fan is on and running when you’re having a shower or a bath – it can have a huge effect on the humidity levels in your bathroom and in your home by sucking that super moist air out before it can condense on surfaces and potentially aid in mold growth. It’s also important to make sure that fan exhausts out of your house and not directly into the attic – and a little yearly maintenance to prevent dust buildup and irritating squeaks will go a long way.
  • Dirt and soap scum: Nobody wants a dirty bathroom, but hospital-level cleanliness isn’t always achievable either. Making sure that dirt, dust, and soap scum are regularly cleaned away can also help prevent mold growth, since these three materials can be all the food mold needs to grow. Make sure you pay attention to all the places in your bathroom – give your shower curtain a wash, look to hard-to-reach corners and underneath the sink too.
  • Leaks and drips: This is the most frequent reason we are called to remove black mold in the bathroom! A leaky pipe, persistent water drip from the corner of the shower, or sweating toilet reservoir are all ways that leaks and drips may be present in your bathroom. Keep an eye out in these important places to catch any problems early.
The major fact about mold growth is that it can grow anywhere in the bathroom from the sides of tiles to the towels, thanks to high levels of humidity. If you want to know the home of mold in your bathroom, you might want to pay attention to following areas. These types of moisture issues are commonly found in most homes, and aren’t indications of a bad housekeeper or messy habits – they’re all part of life. But they can be minimized once you’re aware they’re happening. If you suspect a problem with black mold in your bathroom, you might want to check these common spots that mold grows:
  • Caulks and tiles,
  • plumbing’s,
  • sink, toilet,
  • bathroom window,
  • ceilings, walls,
  • towels,
  • curtains,
  • mats,
  • bathroom robes
  • The bottom edge of the shower curtain
  • Underneath cupboards
  • Between the toilet reservoir and the wall
  • Along tiles, grout, and shower doors
  • In corners and along baseboards
But if you suspect the mold growth in your bathroom or anywhere in your house, seek professionals help for inspecting mould growth in your home, as mold growth is tricky and cannot be spotted easily.

⭐ How To Keep Your Bathroom Mold Free?

Mold resistant bathroom can be created by dealing with the issue of ventilation and controlling the level of humidity in the bathroom. This can be done by using dehumidifiers. It’s also possible if one might find a way to get rid of excess water by evaporators and thoroughly cleaning the bathroom tub and sink. This can also be done by taking proper care of bathtubs, and everything that is involved in the showering process.

The key to protecting your bathroom from mold is to keep everything dry. Paying close attention to the shower curtains, mats and other cloth pieces. It is important to take care of grouts in the bathroom to prevent mold growth. It is important to consult the professionals to create mold resistant bathrooms.

⭐ DIY Mold Removal Process

Are you considering for professional mold removal in Toronto, if you want to remove black mold in the bathroom, many people’s first thought is to go the DIY route. There are many websites, blogs, and home improvement sites with suggestions, tips, and other information on removing mold with bleach, vinegar, baking soda, household cleaners, and other products. The bad news is they’re nearly all ineffective, can spread or increase your mold problem, and don’t address the root of the situation.

Having a Checklist at hand and proper planning is critical to the success of your do it yourself mold removal process. There are many chemicals that are readily available in the market and can help kill mold in your home. To help you out we have updated a mold inspection checklist here which can help you go through the elaborate process of mold inspection and removal easily.

The DIY approach may save you some money initially, but in the long run it leads to bigger problems and increasingly aggressive products to try and get the situation under control. The biggest problem with DIY bathroom mould removal approaches is that it’s frighteningly easy to inadvertently spread the mold to other areas of the room or your home. Reusing sponges is the most obvious problem, but mold is motivated to survive – spores may hitch a ride on your clothes, shoes, bottles, and as you enter and exit the room.

Removing bathroom mold promptly is so important because it causes adverse health effects and can cause serious long and short term harm. Scrubbing away at a moldy spot can release more of the harmful mycotoxins into the air, harming you and anyone else present.

The last reason we never recommend trying to remove mold on your own is that none of the popular DIY removal methods actually work – they’re either too weak to kill the mold, or so toxic they might hurt you or damage your home, while not really harming the mold at all. Bleach is a common household chemical that is more dangerous than most people know – and totally ineffectual at doing more than injuring the surface layer of mold growth.

Hiring an inspector with extensive experience is an important step ahead. You must find one who is well aware of how mold removal works , how to identify various types of mold and their presence in your home, as well as what causes mold growth. 

⭐ How To Identify Mold In Your Home

In-Depth Inspection is a must. This helps to identify the possible areas of concern, where moisture or water may enter the property. Knowing what to look for is the first step in identifying mold, if you want to remove mold yourself.

  • The first is through a visual identification.
  • A Detailed visual inspections inside key areas & air quality tests and reporting will give you the total picture when it comes to mold.
  • While we’ve all had an unfortunate run in with the kind of mold that grows on lunches forgotten in backpacks, household mold can appear very differently. It can resemble a stain or it can be fuzzy; it can be coloured black, white, or green – or even red or blue.
  • Household mold can also be found in many different textures, appearing furry or slick. If you can see mold, it may only be the tip of a much larger problem, and you should call a mold removal professional near you immediately.

The other way to identify mold in your home is by the effects it causes.

  • Mold allergies can strike even the most resilient of people who’ve never taken a sick day or who suffer no other allergies.
  • Mold reproduces by creating airborne spores, and these spores lodge in our respiratory tract, eyes, and nose, and cause cause a great deal of irritation and illness.

Steps for Mold Detection & Removal At Home

✅ Deep scrubbing of soap and water is the your most effective method to remove mold.

✅ You must use a stiff brush on porous surfaces. This is the best way to scrub and disinfect the area by ensuring deep penetration.

✅ Controlling and removing the moisture can also help prevent future outbreaks of mold since the spores can lie dormant until conditions for reproduction become ideal.

✅ Regular air quality testing is essential to maintain your own desired level of air quality for healthy living. The fungus can take hold and grow in many different areas of the home.

✅ The excess wetness turns into humidity and increases the possibility of mold. It makes sense to frequently check and maintain the humidity in your basement.

✅ You can use Hygrometers to gauge and maintain humidity below 50%.

In case you find out that mold presence is causing changes in your health or lifestyle, then, hiring a professional mold inspection expert is your next best step. Trusting the right team for taking care of your your mold issues Is very important.

A detailed air quality test by professionals is the surest way to determine if mold exists in your home. Dark spaces and surfaces like wooden attics basements, drywall and even fabrics are ideal spots for mold development.
