What is Mold Remediation?

Mold remediation is the source removal and/or cleaning of media that is contaminated with mold.  Mold consumes organic material such as wood, Sheetrock and cellulose.   Long term growth of mold can degrade wood and Sheetrock which then requires removal and replacement, this is often the case with water damaged material such as carpeting, ceiling tile, Sheetrock and wood framing.  When conditions are right mold will grow on  the surfaces of inorganic material where a thin layer of organic material maybe present, such as HVAC ducts, concrete, furniture and even exercise equipment.   Mold grows on these surface because inorganic material is present on the surface  such as dust or skin cells.

Most mold remediation is not a DIY (Do It Yourself) project, simple because homeowners don't have the training or access to the necessary equipment to remediate the mold.

Mold remediation is often compared to asbestos abatement or asbestos remediation as the process followed to remediate both both mold and asbestos are similar.   When mold remediation is performed the project starts with the containment of the contaminated area, which is performed to ensure that mold does not migrate to other non impacted rooms or areas.  In finished spaces such as homes and offices, negative pressure containment is established to ensure that spores are controlled and contained.

 If you were  to list a summary of the necessary steps you could condense them into ten steps.    While the completion of each step may not be necessary, you may also find that additional steps are required, this is all dependent on the area that requires remediation.

1. Seal off doors, windows, ducts, ect. in the work area from other areas of the building.

2.Establish a negative air environment utilizing HEPA air filtration.  This creates a contained work environment so the mold will not spread while the remediation is occurring.

3. Ensure all workers have PPE including respiratory protection.  Mold remediation can entail controlled demolition of mold impacted building materials.  This can be hard work and workers are more susceptible to the air born mold spores if they do not have proper respiratory protection.

4. Hepa vacuum loose growth on impacted material.  By HEPA vacuuming surfaces before demolition, you are removing the mold spores that would get airborne. For smoother surfaces, wipe  with an EPA approved fungicide.  This cannot be performed (Wiping ) on non smooth surfaces, which are most wood surfaces such as ceilings in attics and crawl spaces.  The wood in these areas typically do not have a smooth finish so wiping is both impractical and ineffective.

5. Remove and double bag impacted building material and contents that cannot be cleaned such as insulation and damaged Sheetrock.  Bagging the material helps ensure that when mold contaminated material is removed from the work area mold spores are not spread to other clean areas.

6. Hepa vacuum each wall and floor of the rooms, including ceiling and walls.  Again mold remediation is about the REMOVAL of the mold, which often times translates into a thorough cleaning of the area.  

7. In conjunction with hep vacuuming a broad spectrum fungicide can be applied to all surfaces in the space.  This step is performed to both ensure that cleaning was effective and to PREVENT future mold growth as the fungicide will kill remnant spores.   Smooth surfaces in the space can be wiped down with the fungicide (wet wiped) such as walls, floors, ect.   It is unrealistic to think that unfinished wood surfaces can be wiped down such as ceiling and rafters due to wood splintering. 

8. After surfaces have been cleaned, a proactive coating is installed to organic surfaces that were previously impacted with mold.  The coating is fungistatic, meaning it will inhibit FUTURE mold growth.   The coating can be either clear or tinted white.  The white tinted coating is by far the most popular as it is visible on surfaces coated.  Anyone who has painted a room know that areas can be missed so applying a color that is distinct from the original surface color ensures that  the desired area is coated. This coating will also encapsulate the porous surfaces (wood) from absorbing moisture and to kill and remaining mold spores. Re clean the walls and floor with HEPA vacuums after the encapsulate has dried.

9.  Remove remediation equipment and install HEPA Air Scrubbers to cleaning the work room air.  This can be performed for several hours or for days AFTER remediation.  The amount of time that air scrubbing is performed is based on the size of the room(s) as well as the size of the scrubber.  HEPA air scrubbers filters airborne contaminants down to the size of a human blood cell. Post remedial air scrubbing is performed to help polish and air in the room remediate and to ensure that you have captured airborne mold spores.

10. Remove filtration equipment and poly barriers that were installed in STEP 1 so the space can be be reoccupied.

Successful mold remediation includes both the removal of the mold as well as finding the source of the moisture that caused the mold growth.  An often overlooked portion of any mold remediation is the evaluation of what caused the mold growth in the first places and the application of measures to prevent the situation from reoccurring.  Simple put, define what was the moisture source (many times it is sources) and remedy the cause.

    This photo series represents a vacant home where water historically infiltrated the unfinished space of the first floor (slab on grade construction).  A water pipe froze and broke and at one point up to 14" of water filled the space, impacting Sheetrock, insulation and carpets.  
  •  The water entry was discovered within a week, which helped prevent mold growth from spreading too far past the high water mark (mold needs 48 to 72 hours of moisture to start to grow and spread). 
  • Only Sheetrock and insulation up to 24" required removal. All impacted building materials were removed under controlled conditions (negative air). 
  • Only Sheetrock and insulation up to 24" required removal. All impacted building materials were removed under controlled conditions (negative air). 
  • Only Sheetrock and insulation up to 24" required removal. All impacted building materials were removed under controlled conditions (negative air). 
  • Only Sheetrock and insulation up to 24" required removal. All impacted building materials were removed under controlled conditions (negative air). 
  • This photo series represents a vacant home where water historically infiltrated the unfinished space of the first floor (slab on grade construction). 
  • Areas were cleaned with HEPA vacuums and a fungicide applied to kill and residual mold spores. The final approach was applying a white encapsulate containing a long acting fungicide to prevent future mold growth (the historic water entry was repaired) and to ensure that any remaining spores were remediated.
  • Only Sheetrock and insulation up to 24" required removal. All impacted building materials were removed under controlled conditions (negative air).

  •  Only Sheetrock and insulation up to 24" required removal thus saving restoration costs as the entire wall did not require new sheetrock.
