For over 25 years, Blacktrail Environmental mold inspectors have worked in all types of buildings and facilities including skyscrapers of Chicago to all types of oil and industrial facilities. We provide the lowest cost comprehensive inspections for residential homes, office buildings, or industrial facilities. We specialize in writing mold removal work plans and specifications for large cleanup projects. 



Our inspectors are college trained Industrial Hygienists with Bachelor Degrees in science with over 25 years of experience, including volunteering to help residents during the Missouri River and Souris River flood events in 2011. Other "mold consulting" companies advertising on the internet use individuals that have only attended a one-day class to become a "certified" mold inspector, and have no long-term practical experience. Blacktrail's professionals have completed college courses in microbiology that included how to identify the different types of fungi and mold, and their impact to human health. 


Blacktrail's main office is located in Bismarck, North Dakota, and we perform inspections anywhere in North Dakota. We are not a company with an out-of-state call center advertising to "cover" North Dakota, and then sub-contracting a local home inspector with only basic knowledge on how to perform routine air and tape sampling for mold. Some company "inspectors" cannot even tell you if it is mold when they see obvious mold growth, then they tell you they can take a sample and send it to a laboratory at an additional cost to you.


Blacktrail professionals work with the N.D. Department of Health and County Health Officials to solve your mold problems at the lowest cost possible. We will also be here to answer questions after you receive the final report at no additional charge to you. We provide mold consulting services because we care about you and your family's health!

All mold should be cleaned and removed, but if the moldy area is less than about two (2) square feet, in most cases, you can handle the job yourself. 


If there has been a lot of water damage, and/or mold growth covers more than 10 square feet, consult EPA's Mold Remediation in Schools and Commercial Buildings. Although focused on schools and commercialbuildings, this document is applicable to other building types. If you choose to hire a contractor (or other professional service provider) to do the cleanup, make sure the contractor has experience cleaning up mold. Check references and ask the contractor to follow the recommendations in EPA's Mold Remediation in Schools and Commercial Buildings, the guidelines of the American Conference of Governmental Industrial Hygenists (ACGIH), or other guidelines from professional or government organizations.


  • If you suspect that the heating/ventilation/air conditioning (HVAC) system may be contaminated with mold (it is part of an identified moisture problem, for instance, or there is mold near the intake to the system), consult EPA's guide Should You Have the Air Ducts in Your Home Cleaned? before taking further action. Do not run the HVAC system if you know or suspect that it is contaminated with mold - it could spread mold throughout the building.


  • If the water and/or mold damage was caused by sewage or other contaminated water, then call in a professional who has experience cleaning and fixing buildings damaged by contaminated water.
