Interior wall with mold

Modern homeowners are increasingly aware of the dangers of mold infestations. Most molds and fungi are benign. There are thousands of mold spores in the air that people encounter every day with no negative effects.  But if a building becomes infested with mold, it can cause damage to furnishings and surfaces and eventually weaken the building’s structure if it gets into key supports. When mold grows unchecked in indoor living spaces, it can cause health and respiratory problems for some people, especially those suffering from asthma.

While simple mold growth in showers can be handled with household cleaners, once mold has contaminated drywall, carpet padding, or insulation, the job should be handled by professionals. Removing the dead mold is just as crucial as killing live mold. Dead mold particles can have the same negative health effects as living, growing mold.

How do professionals get rid of mold?

1. Identifying and stopping the source of water. Mold cannot grow without water, so whatever is allowing water to enter the space must be fixed, whether it is a leaky pipe, a hole in the roof, failing foundation, or improperly installed downspout or rain gutters.


2. Determining the extent of the mold infestation. It is important to know exactly where the mold is and to make a remediation plan so that you can be sure mold is completely eradicated.


3. Creating a negative air pressure environment. Creating negative air pressure will contain the mold particles and keep them from escaping into other areas.


4. Removal and disposal of all non-salvageable materials. Depending on the severity of the mold contamination, this could include drywall, insulation, carpeting, padding, and soft furnishings.


5. Drying. Mold grows because of excess moisture. Drying out the space is critical to eradicating mold growth.


6. HEPA sanding and vacuuming all surfaces to remove mold. A HEPA vacuum will trap all of the mold particles and ensure that they are removed from the building and do not re-contaminate the space.


7. Washing surfaces with detergent.


8. Cleaning the HVAC system to make sure it is mold free so that you are not breathing in mold or allowing it to re-contaminate the building.

Once the home or business is mold free, it is important to fix the problems that allowed the mold to grow. If the mold growth was due to flooding, flooding is obviously a onetime event. Moisture is always the key to mold growth, so it is important to promptly fix any plumbing leaks and to keep the indoor humidity under 60%. If you live in a damp climate, and your home is prone to condensation, you can help prevent mold growth by installing exhaust fans in bathrooms and kitchens, keeping the building warm, and using a dehumidifier.
