Mold Remediation Procedures
Mold remediation procedures differ from case to case. The
following is a sample of procedures we follow when performing a
1. We will install plastic sheeting as per NYC Department of
Health guidelines, Level I-IV Containment.
2. We will clean the interior air with a HEPA air scrubber.
3. We will remove moisture from the air with an industrial
4. We will remove (sheet rock, carpeting, etc.) in the mold
5. We will HEPA vacuum and wipe all surfaces with an EPA
registered hospital disinfectant that inhibits mold growth.
6. We will coat the area where mold was removed with an EPA
registered fungicidal protective coating.
7. We will remove all debris from the site in 6 ml bags.
HVAC Cleaning Procedures
We perform a thorough inspection and cleaning of all air
handlers, including heating/ air conditioning/ ventilation
units, and all connecting main and branch supply return and/or
exhaust ductwork, diffusers, grilles, dampers and turning vanes.
All work is performed in accordance with NADCA-ACR-2005 and OSHA
standards. Source removal methods are used to remove
contaminants from the air conveyance system.
1. All ceiling diffusers, wall and floor registers are cleaned
2. Supply and return main ducts are brushed and/or whipped with
high powered, compressed, air. (175 PSI)
3. Supply and return branch ducts are brushed and/or whipped
with high powered, compressed, air.
4. All bathroom exhaust ducts are brushed and/or whipped with
high powered, compressed, air.
5. A high efficiency particulate collector with 99.97 efficiency
at .03 microns isconnected at selected points throughout the
HVAC system to remove contaminants and debris.
6. All service openings are sealed with airtight access panels
screwed to ducts.
7. All 2 ½ “ holes or smaller are sealed with airtight knockout
8. Filters are checked and air washed.
9. All duct openings, ceiling diffusers and HVAC units will
receive hospital germicidal disinfectant / deodorizer killing

HVAC SOURCE REMOVAL CLEANING METHOD
1. Prior to the cleaning process, supply and/or return openings
are covered with plastic film to fully protect surrounding areas
from possible loosened debris. Plastic film is then be removed
after relevant clearance testing has been completed and before
the system is restarted.
2. The supply and return networks are zoned in order to be
3. A high efficiency particulate collector is connected at
pre-selected points throughout the HVAC system to evacuate under
negative pressure the areas to be cleaned.
4. The areas to be cleaned are then be air washed, swept with
forward or reverse air, power brushed and/or whipped to remove
all visible dust and debris.
5. All flex ducting where found will be cleaned and air washed
with forward or reverse air sweeps only.
6. All registers, grilles and diffusers will be air washed with
high powered, compressed, air.
7. All service openings cut into the HVAC system to allow access
for cleaning will be sealed with re-usable, airtight, sheet
metal access panels with gaskets screwed to ducts. All 2 ½"
holes or smaller are sealed with airtight knockout plugs.
8. Critical barriers are installed at specific points throughout
system as required to protect completed areas from
