Mold Types & Removal Cost In Toronto

Which are the Most common types of mold found in homes? Mold growth is a hazard. Thats why mold removal in toronto is required at large scale.

Certain types of mold are more dangerous to human health than others.

Mold is an indispensable part of the Earth’s natural recycling process, and because it is so prevalent in the environment, it’s impossible to keep all molds out of a home.

Mold spores 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. This makes mold inspection a very crucial during the whole mold removal process explained in detail in this post.

While some types of mold are more likely to infect a home than others, they all need a humid environment in which to thrive. Consistently damp areas, such as a poorly ventilated bathroom or a vanity unit with a leaking drain pipe, are more likely to develop mold. 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.

Environmental agency guidelines for mold control recommend homeowners clean up small areas themselves, but advise bringing in a mold remediation expert like Batiprosecwhen mold growth exceeds 1 square meter or accompanies water damage.

Mold decontamination involves professional cleaning and removing mold from the home. It may also involve the demolition and removal of building materials, such as partitions and carpet, if these materials cannot be successfully disinfected. It is also a good idea to call in an expert if the mold turns out to be a poisonous variety, if the ventilation has been contaminated with mold, or if sewage has contributed to water damage and mold growth.

Some people are more exposed to health effects. People with mold allergies or asthma may have more severe symptoms.

The following 8 types of mold can be found in and around homes, whether they are visible or not

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, callour mold decontamination experts who can test for mold and determine the best way to get rid of it. On the plus side, many types of mold are black, but most are not actually Stachybotrys.

Aspergillus 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.

This type of allergenic mold often appears under wallpaper when it is removed from walls; it can also grow on bare wood and painted surfaces. Aureobasidium may irritate the skin on contact. When it begins to grow it is light pink or gray, but as it matures it turns deep brownish-black.

Touching Aureobasidium mold and then touching the eyes or face can transfer irritants and cause infection. This type of mold most commonly appears in damp areas, including kitchens and bathrooms, or on porous tile joints. Inhaling the spores can cause typical allergic symptoms such as sneezing and watery eyes.

Acremonium is nearly 100 strains of toxigenic molds that can be found in the pipes and drains of air conditioners and humidifiers. Mold can be difficult to diagnose without testing because it appears in several different colors, including white, pink, or gray. As mold grows, it begins to appear dry and powdery.

Symptoms of exposure to acremonium spores include eye irritation, breathing problems, pneumonia, and even arthritis or fungal infections. If family members have any of these symptoms and you suspect your home has Acremonium mold, call our mold remediation experts to test and eradicate it.

This allergenic and pathogenic mold is more likely to grow after water damage or flooding. Because they thrive in both humidity and darkness, Chaetomium spores often begin to grow in the interior spaces of partitions and may not be visible until the mold has spread to outside the wall. By this time, the fungus has often invaded large areas inside the wall.

Inhaling Chaetomium spores can trigger typical allergic reactions, including watery eyes, sneezing and itchy throat in healthy people, and more severe respiratory symptoms in people with weakened immune systems. The best way to avoid chaetomium is to dry out a house quickly after a flood. Once Chaetomium spreads through interior walls, it usually requires an expert in mold decontamination for its removal.

Some types of mold need heat to survive, but Fusarium thrives and spreads even in temperatures near zero. Fusarium strains can appear almost anywhere. Most strains are allergenic and only cause hay fever-like symptoms, but a few strains can be highly toxic, causing nervous system disorders and internal bleeding. Fusarium is a common risk to garden plants and agricultural crops, and many tomato plants today have been hybridized to reduce Fusarium wilt.

Indoors, 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. Homeowners who live in damp areas can use a dehumidifier.

Penicillin is a valuable antibiotic, but a 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 gets a foothold indoors, it can quickly spread through damp wall panels, soggy carpets, and wallpaper.

An ounce of prevention is worth a pound of cure for this mold. Dry flooded homes as quickly as possible and fix plumbing leaks quickly. Once Penicillium has spread throughout the house, professional mold treatment is recommended.

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.

Some strains can produce mycotoxins, which are volatile organic compounds that can cause serious problems such as lung infections, liver and kidney problems, nervous system problems, and even some types of cancer. Trichoderma mold also releases an enzyme that can cause wood to rot. If your home is compromised by Trichoderma mold, our mold decontamination company is at your service.
