Scope of Work

  1. Assess:
    • Provide our customers background consumer information to help you to understandhealth issues, impacts, causes
    • Understand your needs, health, and building symptoms
    • Recommend tests based on your needs, reported symptoms, and home environment type
    • Explain what is being done during the actual testing process
  2. Identify source
    • Create customized report and action plan
      • Provide all results in plain English
    • Provide you with the context to understand your “house health report card”
      • Show your home’s scores against the benchmarks used from historical analysis
      • Identify areas of concern and conduct root cause analysis
  3. Remediate
    • Recommend action plans, incorporating cost-effective  strategies
    • Assist client in making decision
    • Provide remediation protocol and plans
    • Retest to confirm efficacy

Here are some steps during the assessment and indentifying the source

I.  Complete Visual Mold Inspection

A visual inspection is the most important initial step in identifying a possible mold contamination problem.  The extent of any water damage and mold growth shall be visually assessed by a certified mold inspector/remediator.  This assessment is important to determine remedial strategies.  Ventilation systems shall also be visually checked, particularly for damp filters but also for damp conditions elsewhere in the system, and for overall cleanliness.  Ceiling tiles, gypsum wallboard (sheetrock), cardboard, paper and other cellulosic surfaces shall be given careful attention during a visual inspection.  The inspector shall use hygrometers, a boroscope (fiber optics) and a protimiter (moisture meter), where necessary, to detect hidden mold behind the walls, ceilings and floors and to determine the areas of potential mold growth and continuing moisture penetration. Contact Vioclean for a quote or to make an appointment.

II. Bulk/Surface Sampling

A certified inspector, trained in appropriate sampling methodology, shall perform all necessary bulk or surface sampling.  Bulk/Surface sampling is necessary if the building inhabitants are suffering from health problems which are or may be associated with fungal exposure.  Bulk/Surface sampling is also necessary to identify the presence or absence of mold if a visual inspection is equivocal (e.g. discoloration and staining).  Bulk samples are collected from visibly moldy surfaces by scraping or cutting materials with a clean tool into a clean plastic bag.  Surface samples are collected by wiping a measured area with a sterile swab or by stripping the suspect surface with clear tape.  The surface sample is then transferred to a potato dextrose agar petri dish.  The dish is then incubated in a special incubator that is high in humidity and void of all ambient light at a temperature suitable for fungal growth.  The most accurate mold identification is only possible after seven (7) days of live culturing for the mold cultures to reach their maximum identification growth.  After seven (7) days of incubation, the fungal samples are removed and identified down to genus and to species where possible through visual identification under the microscope.  Contact Vioclean for a quote or to make an appointment.

III.  Air Monitoring

A certified inspector, trained in appropriate sampling methodology, shall perform all necessary air monitoring.  Air samples are collected via an Anderson Style Bioaerosol Sampler.  This type of sampler imparts viable spores on potato dextrose agar petri dishes laced in the apparatus at a rate of 28.3 cubic liters of air per minute.  After a three (3) minute sampling period, the impacted fungi petri dishes shall be incubated in a special incubator that is high in humidity and void of all ambient light.  The impacted fungi petri dishes shall be incubated at a temperature suitable for fungal growth.  The most accurate fungal identification is only possible after seven (7) days of live culturing for the mold cultures to reach their maximum identification growth.  After seven (7) days of incubation, the fungal samples shall be removed and identified down to genus and to species where possible through visual identification under the microscope.  Results shall be provided in colony forming units per cubic meter of air.  Air monitoring is necessary if there is evidence from a visual inspection that the ventilation systems may be contaminated.

The purpose of such air monitoring is to assess the extent of contamination throughout the building.  Sampling should be conducted while ventilation systems are operating.  Air monitoring is necessary if the presence of mold is suspected in a particular area of the structure (e.g. a microbial volatile odor is detected) but cannot be identified through a visual inspection or bulk sampling.  The purpose of such air monitoring is to determine the location and/or extent of mold contamination.  Air monitoring is also necessary if the building inhabitants are suffering from health problems which are or may be associated with fungal exposure.  If air monitoring is performed, for comparative purposes, outdoor air samples should be collected concurrently at an air intake, if possible, and at a location representative of outdoor air.  The outdoor control air test is very helpful in evaluating whether there is an internally generated mold problem.  Such a problem may exist if indoor mold tests report mold levels that are either (a) higher than the outdoor control air test or (b) present indoors but absent from the outdoor control test.  Contact Vioclean for a quote or to make an appointment.
