Mold and Lead Consulting


Sigma’s experienced Mold Assessment Consultant will inspect the building to evaluate the existence, location, and extent of mold growth. If mold is readily visible air and surface samples may be collected to determine the amount and types of mold present. Sigma will document results for the building owner and discuss recommendations for solving the problem.

If mold is found to be present in the building Sigma’s Mold Assessment Consultant will develop the mold remediation protocol that will be followed by the Mold Remediation Contractor.  If desired, Sigma is available to represent the building owner in negotiations with remediation contractors.

At the owner’s discretion Sigma will provide on-site project management to ensure that remediation and safety protocols are being followed.

 At the conclusion of a mold remediation project Sigma conducts a post-remediation assessment to ensure that all visible mold and damaged materials have been removed and the underlying cause has been corrected. Air testing may be conducted to comply with clearance criteria.  When the visual inspection and air sampling results show the remediation has been successfully completed a Mold Remediation Certificate will be issued by Sigma’s consultant.










SIGMA can inspect your commercial/industrial facility for the existence of lead. Two different methods are employed for testing suspect materials. XRF (x-ray fluorescence) is an effective non-destructive methods for determining the presence of lead in paint. Bulk sampling is another method that requires taking samples of suspect materials (also soil and water samples) that are sent to a laboratory for analysis.

Removal of lead from a building requires the development of specific guidelines for the abatement contractor to follow. SIGMA’s extensive knowledge of lead removal procedures and regulations ensures that best practices will be used during the abatement to protect the workers and public. 

During the abatement of lead materials SIGMA provides on-site project management to make certain guidelines of the specifications are adhered to. The SIGMA on-site project manager will ensure that the project is properly completed, that the public and workers are protected during the removal process, and hazardous wastes are properly disposed. After the project is completed SIGMA prepares all final reports to document the safety and health aspects of the project, as well as the success and compliance of abatement methods and project completion.
