Mold Testing

Minneapolis Mold Removal Services offer accurate mold testing services for residential and commercial spaces. We have tested mold areas for several clients in MN and provided a clear outcome after the testing. The outcome was based on scientific backing and knowledge on the job. As a mold consultant, we carry out mold test services to determine the mold growth source, the type of mold, if it’s black mold, more importantly, we observe if the mold would be harmful to the health. We obtain mold samples and transfer them to the laboratory for further analysis, or sometimes we do a manual mold testing right on the spot.

Chemical Tests

Mold formations can be mistaken for dirt formation sometimes. This is a result of the growth's size, which makes the surface where it is formed in dirty. It is sometimes taken as a dirt formation, and the tests must be carried out to confirm what formation it is. A chemical test that could resolve the confusion would be dipping a swab in diluted bleach. Ensure that the bleach mixture is composed of one part of the chemical in sixteen parts of the water. After dipping the swab in bleach, it should be dab on the wall of the surface where the formation occurs. If the spot quickly lightens or keeps coming back after cleaning, then you would know that the formation was truly a mold.

Use of Tools

Another method that could be used to test for the presence of molds would be the screwdriver test method. Mildew molds are molds that are formed on wooden surfaces. These types of molds can be easily ascertained using the screwdriver test method. The screwdriver is used to scratch the surface of the furniture, and if the part being scratched is soft or begins to crumble, you can confirm that the mold began forming, but a rot has started taking rot on the furniture.

Tests Carried out Through Plumbing Leaks

Since molds are known to form moist areas, they probably could be formed on areas where water leaks exist. The chances are that mood near water pipes, water lines, icemakers, or plumbing components have been feeding off nearby water leaks. What is usually done to test for mold formations is to allow the water supply to run while checks are carried out to see if there are damp spots around and if the mold has been formed from the water leak. Since the water can travel in any direction, whether sideways or upwards, it can make its way into any absorbent material. Checks are carried out with a radius of consideration since the leaks may be far from where the mold is formed.

Testing for Outside Leaks

For mold growing on the exteriors of walls or ceilings, the test is carried out to discover leaks on the walls and roofs. Then measurements are carried out from areas of likely mold formation to a reference point, which could be a door. Inspection is then done to see if there are nearby vents, roof flashing, decks, or any show of wood rot. Ground slopes close to the wall should be observed; this can also cause moisture to wick into the foundation and result in mold formation.
