Expert Tips to Prevent and Remove Mold in Your Properties

Updated: Jan 22


Cleaning up mold

Mold is a serious problem that can cause significant health issues for both property owners, residents, and tenants. As a property owner, it's your obligation to ensure the property is safe from mold, but many don’t know how to do this properly.


In this article, we will discuss best practices for detecting and remedying any potential mold issues on your property. We will cover topics such as the types of tests to conduct, techniques to prevent moisture build-up and steps for proper clean-up if mold is discovered. Taking the time to understand and apply best practices will help protect you from costly damage due to mold infestations in the future.


Overview of Mold and Its Health Risks

Mold is a type of fungus that is especially good at destroying organic materials. That means it's a big problem for people and certain household materials—wood, carpet, wall paper, drywall, and more. Mold infestations can cause expensive damage to structures and furnishings but their potential risks to people are even greater. Exposure to mold can lead to respiratory problems, skin irritation, headaches, fatigue, allergies and asthma attacks.


Mold thrives in damp environments and can spread quickly if left unchecked. According to FEMA, mold colonies can grow and begin spreading on a damp surface within 24-48 hours. Property owners have an obligation to ensure their properties are safe from mold infestations by regularly inspecting for signs of moisture build-up or visible growths.

Testing for mold

Testing for Mold

When it comes to assessing the risk of a potential mold infestation, there are several tests that property owners can conduct. The most common type of test is an air sample test but other tests include: surface sample testing, tape lift testing, and bulk sampling.


Air Sample Testing

An air sample test involves collecting samples of air from the area where you suspect mold growth and sending them off for laboratory analysis. They're the most common type of mold testing because they provide an accurate representation of the types and amounts of mold spores present in the air.


An effective air sample test can identify the presence of different types of mold spores, which allows for a more targeted approach to remediation. Air sample tests require specialized equipment and knowledge to conduct properly, so it's best to consult a professional before attempting them yourself.


Surface Sample Testing

Surface sample testing is a method to assess the presence of mold on an indoor surface such as walls, floors, ceilings, and furnishings. This type of testing involves swabbing affected areas with a moistened swab or collecting dust particles from the air to be tested in a laboratory.


The advantage of this type of testing is that it provides an accurate picture of the mold present on a specific surface. The disadvantage is that the swab or dust samples may not always be representative of the entire area, so a surface sample test should be followed up by an air sample test to ensure accuracy.


Tape Lift Testing

Tape lift testing involves pressing a piece of clear tape onto suspected mold growth and then lifting it off the surface. The tape is then analyzed in a laboratory under a microscope to determine the type and amount of mold present. This method provides an easy way to detect mold and identify the type of mold without having to collect a sample from the affected area.


Bulk Sampling

Bulk sampling requires removing a sample of material from the affected area and sending it off for laboratory analysis. This type of testing usually involves collecting small amounts of materials such as dust or insulation.


The advantage of bulk sampling is that it allows for an accurate assessment of the type and amount of mold present in a specific area. However, it can be difficult to collect an accurate sample due to the difficulty in reaching certain areas such as wall cavities or attics.

Preventing Mold Growth on Your Property

Mold thrives in moist environments so it’s important for property owners to take steps to prevent moisture build-up. These include inspecting gutters and downspouts for proper drainage, ensuring any leaks are addressed immediately, maintaining proper ventilation, and using a dehumidifier in areas with high humidity. Additionally, it’s important to check for any signs of water damage such as peeling paint or discolored walls.


To control moisture levels on a property, it's important to identify any areas that are prone to dampness and actively monitor them for signs of excessive moisture. Common areas where moisture can build up include around windows, under sinks, in basements, and in other areas where water may have leaked or been spilled. If these areas are left unchecked, it can create a perfect environment for mold to thrive.


Good ventilation is also important in preventing moisture build-up and the growth of mold. If your property has poor ventilation, you may need to install additional exhaust fans or open windows when possible. Additionally, using an air purifier with a HEPA filter can help remove airborne mold spores from the indoor environment.


Steps for Proper Clean-Up

Mold removal from a property is an arduous process that requires the expertise of experienced mold remediation specialists. The first step in the process is to identify and address the source of moisture build-up on the property, as this is what allowed the mold to thrive in the first place. This can include repairing plumbing leaks, sealing any cracks in the walls, and making sure ventilation is adequate.


After the source of moisture has been addressed, mold remediation experts can begin to remove the mold from the affected areas. This may involve physically scrubbing down surfaces or using chemical solutions to kill off any lingering spores. It is important to note that this process should only be done by trained professionals, as some mold species can be hazardous to your health and may require special handling.
