Mold Assessment and Moisture Intrusion Services
Health Risks Associated With Mold
Mold is perhaps the most controversial and misunderstood home health concern. Many in my business are eaqer to exaggerate the health risks associated with black mold or molds in general as a way of promoting the business. However, on the other hand many building owners and contractors are too eager to entirely dismiss the health concerns associated with mold. The truth is that mold does not follow the patterns and models associated with other indoor air contaminants. Mold is an evolving concern that does not follow any convenient philosophy. The science of mold testing itself is controversial for those who try to overthink things. Mold is one of those things that is merely a nuisance and irritant for a majority of the population. Yet every once in a while it inconveniently surprises us. For example, I know of an asthmatic that collapsed and died unexpectedly in a grocery store. Based on the variety of food odors and moisture sources, a grocery store that is not well-kept can be a bazaar of different molds.
Tri-Tech brings a balanced "big picture" approach to mold assessment. In reality, much of the concern associated with mold is based on rather mundane allergenic effects rather than risks of infection or other chemical hypersensitive effects, both of which are uncommon. In my experience, too much emphasis is placed on disinfection, which is generally not necessary since the main concern associated with mold is its allergenic potential, which is unrelated to whether mold is "living" or "dead."
Mold Assessment and Abatement
The general approach to dealing with mold is to remove/correct the moisture source and remove the damaged building materials. Most mold projects can be dealt with a restoration projects rather than mold abatement projects. What is the difference? Speed. If you remove the mold and the moisture source, the mold will eventually go away on its own through ventilation, natural degradation and other attenuation mechanisms. However, mold spore counts will likely remain high for days or weeks if mold is removed without special precautions or controls. Mold abatement is appropriate when speed counts and mold needs to be removed and a living space restored quickly for re-occupancy.
There are no mold regulations in Michigan. The lack of mold regulation is beneficial in that it allows a flexible and pragmatic approach to a given mold situation and costs can be balanced against the timetable for completion of the project. In a few circumstances, duct cleaning is performed as part of a mold abatement project.
Mold testing services can fill the following role in restoration and abatement projects:
• Defining the background level of mold in a house when a limited scope project is undertaken and funds are not available to do a full mold cleanup of a building.
• Determining the type of mold present. Homeowners and contractors performing restoration projects will be more at ease knowing the mold is not a high-risk mold type. Many will opt to leave dealing with high-risk mold types to the professionals although this is not necessarily required for non-allergic personnel who take some precautions.
• Defining the mold spore levels in a building following completion of a restoration or abatement project. The air test results can be used to provide assurances that the mold spore levels are "safe" and that no hidden or chronic problem remains.

Sometimes only a visual inspection for mold is required for a property transaction or for other purposes. Sometimes general inspections or appraisers will over-exaggerate mundane mold issues or just want to get a second-opinion on a mold issue. Sometimes a homeowner just wants an able-bodied inspector to go up in an attic and take a look-around to see if there are any problems. Tri-Tech can assist with most mold inspection needs.
