What causes mould growth?

While mould can grow in a variety of conditions, the key component is moisture. Floods are breeding grounds for mould, but a small leak — such as behind the walls, around pipes, etc. — can also lead to fungal growth. Airflow is another factor. If the air is stagnant and no fresh air can enter the space, this fosters the conditions for mould growth.

I found a leak/we just experienced a flood. How long do I have before mould starts to grow?

Mould can start to grow within 48 hours. But if you act fast you can prevent that from happening. If the leak/flood happened before the 48-hour mark, dry the area as thoroughly as possible. We rent dryers that will dry a variety of spaces quickly and efficiently.

I just had a home inspection and the inspector found black discolouration on the sheeting board in the attic? What do I do?

Getting rid of mould will depend on where it’s located and the extent of the growth. Our main concern is identifying the cause. The common reason for mould growth in attics is improper ventilation. This can often result from blocked soffits or blocked gable and ridge vents. Make sure there are enough roof vents in the attic to allow for air to flow. Another reason can be if the bathroom vent is pumping air into the attic. Be sure to use a flex pipe that vents air from the bathroom outside of the home and not into the attic. Finally, leaks can also lead to mould growth. This can result from improper flashing around chimneys or old shingles. Call us immediately should any mould be detected.

My bathtub/toilet flooded my bathroom. What do I do?

Usually in bathrooms mould will start to grow up from the baseboard — because of gravity the water falls, so growth will generally start near the floor. We will have to first remove the baseboard and assess the damage. From there, we will go up two or three feet and remove the drywall and vapour barrier to investigate the extent of the growth. After we determine how extensive the growth is, we can devise a remediation strategy.

We had a flood and now black dots are forming on the baseboard. Help?

After a flood, call us and we’ll give you as much information as possible to allow you to safely navigate the mould removal process. We’re certified by the Workplace Safety and Insurance Board (WSIB) and follow strict guidelines for mould remediation. We’ll help you follow those rules as well. Once you contact us, we’ll send over one of our professionally trained mould experts who will begin the investigation and consultation. This involves taking photographs of the mould growth and measurements of its extent to determine the correct path for remediation. We provide thorough documentation to all our clients to ensure regulations are met and you find peace of mind.

I can’t see any mould but there’s a musty odour. What does that mean?

Just because you can’t see mould doesn’t mean it’s not there. Mould can grow behind walls, under carpet and in ceiling tile. A thorough air quality test will be required to determine what’s present and where it’s growing. We prefer to avoid charging customers for unnecessary services, so before you call us, we recommend that you air out your entire house and give it a top-to-bottom cleaning, which includes your ducts. This may rectify the musty smell and save you money. If you still smell something after all that, give us a call.

You’re WSIB-certified. Why is that important to me?

Our WSIB certification means that you, as a home or property owner, are covered for any mishap that may occur on the job site. If a workplace accident should occur in your home or office and the individual you hired does not have WSIB certification, you can be held liable for the injuries they incur. With our comprehensive insurance and WSIB certification, you can rest assured that you will not be held liable for anything that happens while on your property.

Our professional technicians are also covered by pollution insurance. This is integral for asbestos removal, which is often found in old homes and buildings built in the ’50s, ’60s, ’70s and ’80s.

How can I prevent mould growth?

While it’s impossible to mould-proof your home, you can take steps to lessen the chance of growth, such as using dehumidifiers to mitigate moisture in the air and ensuring there is adequate air flow in your home. Check our Mould Prevention section for a list of steps you can take to prevent mould growth.

I’ve had an insurance company inspect my home after a flood/fire. Do I need anything from them before I call you?

Whenever you have an insurance company inspect your home, be sure to document or get documentation on everything they do. Are they setting up proper containment? Are they following the guidelines for mould remediation? Did they collect air samples? Ask for their references and any other documentation. This will help you cover all your bases should they not preform any of the procedures according to legal guidelines. Once you get these answers from the insurance company, pass that information on to us so we can formulate the correct course of action to remediate your situation.

How long will you be there after I call?

We understand the anxiety that comes with finding mould. As such, generally we’ll be there within one or two hours after you call. At most, we’ll be at your location within 24 hours. If we’re heavily booked during the day, we’ll make arrangements to have a technician examine your property after hours. We’re here to accommodate your needs.
