From The Experts At St. John Environmental Consulting

Asbestos is a natural mineral that is found in some building materials, and is known to be a hazardous carcinogen. Building owners and contractors must perform testing or site surveys prior to disturbing or demolishing a building or building materials that may contain asbestos. Although most people are aware of the potential for asbestos content in pipe insulation, 9×9 floor tile, transite siding, and floor mastic; any building material that is not made of wood, metal, or glass may contain asbestos.

The Process Of Testing For Asbestos



Any time you are remodeling, demolishing, repairing or otherwise disturbing materials that may contain asbestos, an asbestos inspection is required.


Asbestos Testing

An AHERA accredited inspector will help you to determine the appropriate asbestos sampling plan and protocol to ensure that you protect yourself from health impacts and liabilities of asbestos, without wasting money on abating unnecessary materials.



It is always better to hire a qualified professional for the removal and remediation process.  We can provide you with a list of qualified remediation companies and consult with them for an additional fee.

Types Of Air Testing For Asbestos Fibers

Asbestos fibers in air are generally tested by one of two methods, either PCM (phase contrast microscopy) or TEM (transmission electron microscopy). These two methods are drastically different, and should be understood before the testing begins.

Phase contrast microscopy (PCM) is a method that measures only the total number of fibers in the air and does not differentiate between asbestos and other types of fibers. Additionally, PCM testing does not measure the smallest fibers and can miss significant asbestos hazards

Transmission Electron Microscopy (TEM) is a method that captures even very fine fibers and reports only on those that are asbestos fibers. This method allows us to truly assess the hazards that may be present due to asbestos fibers in the air.

When You Need An Asbestos Inspection:

Any time you are remodeling, demolishing, repairing or otherwise disturbing materials that may contain asbestos, an asbestos inspection is required. Asbestos is not illegal in other countries and can even be in modern building supplies.

Floor-Plans & Sampling

A good survey will include floor-plans with the locations of all suspect materials clearly labeled. This takes time, but is invaluable to the client. With this detailed information it is easy to get pricing on abatement and walk regulators through the project. Any samples taken of a suspect material should be taken in either 3, 5, or 7 samples for each material. An accredited lab will read the results and anything over 1% asbestos is considered asbestos containing. A good report will list all of the samples tested weather positive or negative.

Asbestos Air Monitoring

Many clients become concerned that asbestos fibers or asbestos containing dust may be present in their buildings. This dust may be due to damaged materials that contain asbestos, left-over from an abatement project, or created by remodeling or demolition work. When these concerns arise, we are often asked to perform asbestos air sampling or asbestos monitoring. Below you will find some general information about how these services can be performed.

"This company is great and goes above and beyond for their clients. I had researched other companies and heard about St. John Environmental and gave it a try. To say this company exceeded my expectations is an understatement. The owner goes over every last detail and leaves nothing untouched. If it’s not absolutely %150 up to standard he is not satisfied whatsoever. I love a company that can leave a job knowing there was nothing unfinished and did an awesome job. Highly recommended. If I could give more stars I would..”
