The Ultimate Guide to the 5 Mold Remediation Levels

November 30, 2020 at 10:30 PM
There are five levels of mold remediation, most of which require professional invervention.

The square footage affected by contamination establishes the five levels of mold remediation. At Level Five - the most severe contamination - the mold grows in an HVAC system or air conditioner and is, effectively, airborne.

At all levels of remediation, some individuals should take care to stay far away from the contaminated area:

  • Babies under a year old.
  • People who have had surgery and are still recovering.
  • Those who are immuno-compromised.
  • People with allergies or asthma.

By familiarizing yourself with the levels of mold remediation you’ll know when to call in the experts for help.

Level One: Less than 10 square feet.

When mold is this contained, it’s tempting to treat on your own. Level One is common on ceilings, from a roof leak or around baseboards, from flooding. There are some key things to keep in mind if you attempt Level One mold remediation on your own:

  • Wear extensive PPE, including an N95 respirator, goggles, gloves, and disposable Tyvek suit.
  • Dispose of anything moldy in sealed bags to prevent the spread of contamination.
  • Thoroughly clean the area with soapy water following mold removal.

Keep in mind, a Level One contamination can spread to become Level Two or even to a new site in your home. A professional mold remediation company can quickly and permanently stop the contamination.

Level Two: 10 to 30 square feet.

Level Two is typically a mold infestation that has covered a single wall panel. Many homeowners feel tempted to attempt remediation on their own:

  • Use the same precautions at Level One.
  • Moldy materials should be double-wrapped in plastic before disposal.
  • Clean with a high-powered vacuum followed by soapy water.

It’s tough to know when a mold problem has spread beyond what a homeowner can handle. A mold remediation company offers peace of mind by inspecting the moldy area and thoroughly treating it.

Level Three: 30 to 100 square feet.

At this point, the mold has covered anywhere from multiple walls to an entire room. If you’re dealing with this level of mold contamination, take these precautions:

  • Seal off ventilation and heating ducts to prevent the mold from entering the HVAC system.
  • Keep at-risk individuals far away from the area.

It’s easy for mold to spread beyond a single room to an entire home or business. If you’re dealing with Level Three mold remediation, professionals can offer expertise and guidance.

Level Four: Over 100 square feet of contamination.

If substantial parts of your home have mold, isolate them using plastic sheeting. When possible, move out of the house while a professional mold remediation company treats the contamination.

This degree of mold clean-up requires experience handling hazardous material and high-quality PPE. Green Clean Remediation has experience treating all levels of mold remediation with eco-friendly solutions.

Level Five: Air conditioner units and HVAC systems.

A mold remediation company will use an assortment of biocides to prevent the growth of mold spores. These are broad-spectrum antimicrobials designed to both kill current mold and stop the mold from returning. Removing mold from AC and HVAC systems requires professional expertise using HVAC-safe chemicals and agents.
