Mold Testing

Mold Testing 2018-05-21T18:04:45+00:00

The reason to do mold testing is if you want to know what kind of mold species are found in your house. This is important for toxic molds, with which you must be very careful and to remove them safely from the house.

Two well-known toxic fungi are Stachybotrys (often called toxic black mold) and Aspergillus.

If you see a mold that looks like a toxic species or if you are suffering from toxic symptoms, then you should do the tests before trying to eliminate it. The only way to identify the species of a mold colony for sure is hiring a mold professional to make an observation of a sample under a microscope.

Tests to find mold

Mold tests will not only tell you if you have a mold problem somewhere in your home, but they can also help you find it.

Mold often grows hidden behind walls and other places. Mold tests can help limit the location of hidden mold by indicating where there are more mold spores in your home.

Mold tests for indoor air quality

At Green Environment Testing we can perform mold tests to know the amount of spores in the air.

Sometimes, you may be suffering from the symptoms of mold allergies, even if there is no mold in your home. This may be due to the mold spores that fly into your home from the outside or because previously there was mold growing in your house and left behind an accumulation of spores.

By doing the mold tests we can find out if there is an unhealthy level of spores in your home and find out if any allergy you may have is caused by mold or by some other cause.

Mold tests after removing mold

The tests can be useful after removing the mold from your home. Thanks to the tests, we can make sure that the elimination of the mold was a success.

Samples taken from surfaces can show if an area has been properly cleaned of mold. Check the air some time after the removal of the mold, we can also confirm that the mold spores in the air of your house have been reduced to a safe level.

Multiple tests

A mold test gives you a snapshot of the amount of mold particles in a given area at a given time. But the amount of mold spores fluctuates in time and from place to place.

Because of this, it is a good idea to take tests at different times and in different places in your home. This way you will get a more complete and accurate picture of the mold problem in your home.

By doing mold tests, we can know if you have a problem at home. Mold tests also measure the amount of spores in your home’s air and can identify which species you have.

The three main types of tests that can be done are the following:

  • Air tests.
  • Tests on surfaces.
  • Massive tests

The ideal is to use the three types of tests since each one has its own advantages and disadvantages.

Test in the air

Air sampling tests the concentration of mold spores in your home’s air. Air samples are taken and then examined under a microscope.

The tests in the air can tell you if you have a mold problem, even if you can not find the mold growing. However, the amount of mold spores in the air can change drastically in a short time, giving different results at different times.

Mold inspection before testing

Before resorting to mold tests, you should have made a thorough inspection of the mold in your home. If mold appears during the inspection, it is usually not necessary to perform any mold test. Instead, we can move on to the mold removal stage.

But if you have not been able to find any mold but you still think that you have a mold problem, or if you have found some mold but you think there is more hidden or toxic, then it is time to resort to mold testing.

Tests On Surfaces

Surface testing involves taking samples from home surfaces to find the amount of mold growth and spores deposited around the home. The samples are collected with a swab (rubbing), lifting tapes or other methods. Then the samples are examined in a laboratory.

As with air testing, the results may vary, because the growth of mold and spores is not distributed evenly across surfaces in the home and may change over time. Unlike air tests, however, the tests on the surfaces can not identify the exact concentration of mold spores in the air.

Massive Tests

Massive tests include the collection of pieces of material from the house. The material is taken to a laboratory where the mold particles of the material are examined under a microscope. Massive tests can tell you if you have a mold problem and give you an idea of ​​the concentration of mold particles in your home.

Mold culture tests

Cultivation tests are those that are made by taking a sample of the mold particles from the house and cultivating them in a laboratory until they become large mold colonies. In this way, with the culture tests identify the mold species that are in the house.

Only mold particles that are still alive can be grown. However, the dead mold particles in the house still cause allergies and health problems. There are other tests that can detect both live and dead mold in a house, but they can not always identify the mold species.
